Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a video information processing apparatus that performs moving image editing, and in particular, a video information processing apparatus capable of generating a title for editing during recording and performing the editing process in parallel with the recording process, and The present invention relates to a video information processing method.
[0002]
[Prior art]
In recent years, DVD video recorders using recordable DVDs have been put into practical use. An HDD video recorder using an HDD has also been developed. Furthermore, hybrid recorders that have both a removable removable DVD and a large-capacity HDD have also appeared.
[0003]
In conventional video tape recorders using magnetic tape, it is necessary to edit multiple recorded video tape recorders or edit them to perform operations such as editing recorded content, such as deleting unnecessary scenes or extracting necessary scenes. Equipment etc. are necessary. This is due to the characteristic of the tape media that recording is performed in a straight line in the running direction of the tape.
[0004]
On the other hand, disk media such as DVDs and HDDs have a feature of excellent random accessibility. For this reason, video recorders using these disk media can incorporate the editing function of the recorded content in the video recorder main body without using a special editing device. Specifically, what is called playlist editing, in which partial reference information indicating a part of recorded content is bundled, is generally used.
[0005]
The recorded content is recorded as a title having audio information and video information itself. This is called the original title. On the other hand, there is a title that does not have unique audio / video information and is composed only of reproduction order information for audio / video information of other original titles. This is a title created by an editing operation called a playlist title (or simply a playlist).
[0006]
Since this playlist editing is for constructing playback order information for content that has already been recorded on a disk medium such as a DVD or HDD, it is basically premised that it is performed after the recording is completed. Therefore, in order to create a playlist that refers to an original title that is currently being recorded, it is necessary to wait until the recording of the original title is completed.
[0007]
However, for example, when air-check recording a TV program, it takes a relatively long time to complete the recording. Therefore, it is inconvenient that no editing operation can be performed on the title being recorded. is there.
[0008]
That is, as a process performed by the user for the recorded title, for example, an unnecessary scene such as a CM is cut and only a necessary main video is left. In this case, even if the recording is in progress, if the processing such as cutting unnecessary scenes can be realized for the already recorded part at any time, the user's usability is improved. However, such processing must be performed after the end of recording.
[0009]
As a conventional technique using such a playlist, there is known a video editing system in which the concept of a temporary playlist for confirming a state after editing while recording is in progress (see, for example, Patent Document 1). . In such a video editing system, although it is different from a DVD recorder, it seems that a playlist editing of a title in progress of recording can be realized by diverting the concept of the temporary playlist described here.
[0010]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 11-146334.
[0011]
[Problems to be solved by the invention]
However, this prior art is premised on recording from the VTR to the HDD, and after setting the necessary range by editing operation on the VTR for which recording has been completed in advance, recording to the HDD is performed. Thus, a playlist using the range information is created. That is, it is necessary to select only necessary information at the level of source information such as a VTR and then record it on the HDD. Therefore, in the prior art, while recording a broadcast in a state where necessary scenes and unnecessary scenes are mixed as in air check recording, the user records one by one for such video information during recording. Therefore, there is a problem in that it is impossible to perform an editing operation such as determining whether it is necessary or not and leaving a necessary part.
[0012]
The present invention has been made to solve such a problem, and relates to a title in progress of video recording, and a video information processing apparatus and video information processing method capable of performing playlist editing without waiting for the end of the recording. The purpose is to provide.
[0013]
[Means for Solving the Problems]
The present invention provides recording means for recording input video and audio information on a recording medium as a first title including actual information of the video and audio, and recording is already performed during recording of the first title. Editing means for generating a second title including reference information to the actual video and audio information of the first title of the portion that has been recorded, and editing the second title. This is a video information processing apparatus.
[0014]
In the video information processing apparatus according to the present invention, a playlist which is an editing title is generated in parallel with the recording process before the recording process is completed, and the editing title is played during the recording. The list is edited. When recording progresses, for example, every time the editing operation screen is opened, the editing title is updated in accordance with the progress of the title until the recording progresses. is there.
[0015]
As a result, even before all the recording is finished, for example, editing processing such as deleting CMs of the broadcasted program is performed by the user's operation in parallel with the recording processing within the recording finished range. be able to. Therefore, according to the present invention, it is possible to provide a video information processing apparatus capable of performing very efficient editing processing without waiting for the end of recording.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0017]
<Outline of Video Information Processing Apparatus According to the Present Invention>
FIG. 1 is a block diagram showing a schematic configuration of a video information processing apparatus according to an embodiment of the present invention. In this embodiment, an apparatus capable of handling both a DVD-RAM and a hard disk as a recording medium is shown. However, the hard disk or the DVD-RAM may be replaced with a recording medium such as a semiconductor memory.
[0018]
When the blocks in FIG. 1 are roughly divided, the main block of the recording unit is shown on the left side, and the main block of the playback unit is shown on the right side.
[0019]
The video information processing apparatus in FIG. 1 has two types of disk drive units. First, it has a disk drive unit 23 that rotationally drives an optical disk D as a first medium, which is an information recording medium that can construct a video file, and executes reading and writing of information. Further, it has a hard disk drive unit 21 for driving a hard disk as a second medium. The data processor unit 22 can supply recording information to the disk drive unit 23 and the hard disk drive unit 21 and can receive a reproduced signal. The disk drive unit 23 includes a rotation control system, a laser drive system, an optical system, and the like for the optical disk D.
[0020]
The data processor unit 22 handles information of recording or reproduction units, and includes a buffer circuit, a modulation / demodulation circuit, an error correction unit, and the like.
[0021]
Further, the video information processing apparatus of FIG. 1 mainly includes an encoder unit 50 that constitutes a recording side, a decoder unit 60 that constitutes a reproduction side, and a microcomputer block 30 that controls the operation of the apparatus body.
[0022]
The encoder unit 50 includes a video and audio analog-to-digital converter that digitizes an input analog video signal or analog audio signal, a video encoder, and an audio encoder. Furthermore, a sub-picture encoder is also included.
[0023]
The output of the encoder unit 50 is converted into a predetermined DVD-RAM format by a formatter 51 including a buffer memory and supplied to the data processor unit 22.
[0024]
The encoder unit 50 receives an external analog video signal and an external analog audio signal from the AV input unit 41 or an analog video signal and an analog audio signal from the TV tuner 42.
[0025]
The encoder unit 50 can also supply the compressed digital video signal or digital audio signal directly to the formatter 51 when a directly compressed digital video signal or digital audio signal is directly input. The encoder unit 50 can also directly supply a digital video signal or audio signal that has been subjected to analog-digital conversion to the video mixing unit 71 or the audio selector 76.
[0026]
In the video encoder included in the encoder unit 50, the digital video signal is converted into a digital video signal compressed at a variable bit rate based on the MPEG2 or MPEG1 standard. The digital audio signal is converted into a digital audio signal compressed at a fixed bit rate based on the MPEG or AC-3 standard, or a linear PCM digital audio signal.
[0027]
When a sub-video signal is input from the AV input unit 41 (for example, a signal from a DVD video player with an independent output terminal of a sub-video signal), or a DVD video signal having such a data structure is broadcast and is transmitted to a TV tuner. When received at 42, the sub-video signal in the DVD video signal is encoded (run-length encoded) by the sub-video encoder to become a sub-picture bitmap.
[0028]
The encoded digital video signal, digital audio signal, and sub-picture information are packed by the formatter 51 to become a video pack, an audio pack, and a sub-picture pack, and these are assembled to form a DVD-recording standard (for example, DVD-RAM). , DVD-R, DVD-RW, etc.).
[0029]
Here, the apparatus of FIG. 1 uses the data processor unit 22 to send information (packs of video, audio, sub-picture information, etc.) formatted by the formatter 51 and the created management information to the hard disk drive unit 21 or the data disk. It can be supplied to the drive unit 23 and recorded on the hard disk or the optical disk D. Further, information recorded on the hard disk or the optical disk D can be recorded on the optical disk D or the hard disk via the data processor unit 22 and the disk drive unit 23.
[0030]
It is also possible to perform an editing process such as deleting a part of video objects of a plurality of programs recorded on the hard disk or the optical disk D or connecting objects of different programs. This is because the information unit handled by the format according to the present invention is defined to facilitate editing.
[0031]
The microcomputer block 30 includes an MPU (micro processing unit) or CPU (central processing unit), a ROM in which a control program and the like are written, and a RAM for providing a work area necessary for program execution. It is out.
[0032]
The MPU of the microcomputer block 30 executes defect location detection, unrecorded area detection, recording information recording position setting, UDF recording, AV address setting, etc., using the RAM as a work area according to the control program stored in the ROM. To do.
[0033]
The microcomputer block 30 has an information processing unit necessary for controlling the entire system, and includes a work RAM 31, a directory detection unit 32, a VMG (total video management information) information creation unit, and a copy related information detection unit. A copy and scrambling information processing unit (RDI processing unit), a packet header processing unit, a sequence header processing unit, an aspect ratio information processing unit, and the like.
[0034]
The microcomputer block 30 also includes a control unit 34 for management information when executing recording, and a control unit 33 for management information when executing editing, which can perform editing processing during recording. Various features, which are the features of the present invention, will be described later as the first to eighth embodiments, and are executed in the form of a control program by the control unit for management information when executing this editing.
[0035]
Among the execution results of the MPU, the contents to be notified to the user are displayed on the display unit 43 of the video information processing apparatus or displayed on the monitor display as OSD (on-screen display). The microcomputer block 30 has a key input unit 44 for giving an operation signal for operating this apparatus.
[0036]
The timing at which the microcomputer block 30 controls the disk drive unit 23, the hard disk drive unit 21, the data processor unit 22, the encoder unit 50 and / or the decoder unit 60 is time information from an STC (system time clock) 38. Can be performed based on. Recording and playback operations are normally executed in synchronization with the time clock from the STC 38, but other processes may be executed at a timing independent of the STC 38.
[0037]
The decoder unit 60 separates and extracts each pack from a DVD format signal having a pack structure, a memory used when pack separation or other signal processing is performed, and main video information (video pack of the video pack) separated by the separator. A V decoder that decodes the content), an SP decoder that decodes the sub-picture information (sub-picture pack contents) separated by the separator, and an A decoder that decodes the audio information (the contents of the audio pack) separated by the separator. Have In addition, a video processor is provided that appropriately synthesizes the decoded sub-video with the decoded main video, and outputs the menu, highlight button, subtitles, and other sub-videos superimposed on the main video.
[0038]
The output video signal of the decoder unit 60 is input to the video mixing unit 71. In the video mixing unit 71, text information is synthesized. The video mixing unit 71 is also connected to a line that directly takes in signals from the TV tuner 42 and the A / V input unit 41. A frame memory 72 used as a buffer is connected to the video mixing unit 71. When the output of the video mixing unit 71 is an analog output, it is output to the outside via an I / F (interface) 73, and when it is a digital output, it is output to the outside via a digital / analog converter 74.
[0039]
The output audio signal of the decoder unit 60 is analog-converted by the digital-analog converter 77 via the selector 76 and output to the outside. The selector 76 is controlled by a select signal from the microcomputer block 30. Accordingly, the selector 76 can directly select a signal that has passed through the encoder unit 50 when directly monitoring a digital signal from the TV tuner 42 or the A / V input unit 41.
[0040]
Note that the formatter of the encoder unit 50 creates segmentation information during recording and periodically sends it to the MPU of the microcomputer block 30 (information at the time of GOP head interrupt, etc.). The segmentation information includes the number of VOBU packs, the end address of the I picture from the beginning of the VOBU, and the playback time of the VOBU.
[0041]
At the same time, information from the aspect information processing unit is sent to the MPU at the start of recording, and the MPU creates VOB stream information (STI). Here, the STI stores resolution information, aspect information, and the like, and at the time of reproduction, each decoder unit is initialized based on this information.
[0042]
In this apparatus, one video file is recorded on one disc. Further, in order to continue reproduction without interruption while accessing (seeking) information, a minimum continuous information unit (size) is determined. This unit is called CDA (Contiguous Data Area). The CDA size is a multiple of an ECC (error correction code) block (16 sectors), and the file system records in this CDA unit.
[0043]
The data processor unit 22 receives information in units of VOBU from the formatter of the encoder unit 50 and supplies information in units of CDA to the disk drive unit 23 or the hard disk drive unit 21. Also, the MPU of the microcomputer block 30 creates management information necessary for reproducing the recorded information. When the MPU recognizes a recording end command, the MPU sends the created management information to the data processor unit 22. Thereby, the management information is recorded on the disc. Therefore, when encoding is performed, the MPU of the microcomputer block 30 receives information unit information (eg, segmentation information) from the encoder unit 50. The MPU of the microcomputer block 30 recognizes the management information (file system) read from the optical disk and the hard disk at the start of recording, recognizes the unrecorded area of each disk, and sets the recording area on the information to the data processor unit 22. Is set to disk via.
[0044]
Next, the relationship between the management information and the actual video information that is the content will be briefly described with reference to FIG. FIG. 2 is a diagram showing a relationship between management information of content recorded by the video information processing apparatus according to the embodiment of the present invention and real video information.
[0045]
In FIG. 2, the actual video information 80 will be described first. Here, it is assumed that the real video information 80 is collected into one file on the recording medium. One file is composed of one or a plurality of actual video information streams 81. Each actual video information stream 81 may be a unit recorded by one recording process, for example. This corresponds to, for example, VOB (video object) in the DVD recording standard. One real video information stream 81 is composed of one or a plurality of stream partial areas 82. This corresponds to, for example, VOBU (video object unit) in the DVD recording standard, GOP (group of picture) in the MPEG2 standard, and the like. One stream partial area 82 is composed of a plurality of packs. As the plurality of packs, there are an information pack 83, a video pack 84, an audio pack 85, and the like. Further, a sub-picture pack 86 may exist.
[0046]
The information pack 83 corresponds to, for example, an RDI pack in the DVD recording standard. In this case, this pack includes information indicating the start time when the first field of the VOBU to which the pack belongs is reproduced, information indicating the recording time of the VOBU, manufacturer information (MNFI), and the like. It also includes display control information (DCI) and copy control information (CCI). The display control information indicates aspect ratio information, subtitle mode information, and film camera mode information. The copy control information includes copy permission information or copy prohibition (non-permission) information.
[0047]
The video pack 84 is obtained by compressing video information by the MPEG2 system and includes a pack header, a packet header, and a video information section.
[0048]
The audio pack 85 is obtained by processing audio information by a method such as linear PCM, MPEG, or AC-3, and includes a pack header, a packet header, and an audio information section.
[0049]
Next, the management information 90 will be described.
[0050]
In the management information 90, original title (program) information T1 which is information (playback order information) for managing the playback order of the real video information 80 is defined. This corresponds to, for example, programs 93-1 to 9-n in the DVD recording standard. Reference information 94-1 to 9-n is defined in each original title information (or program information) 93-1 to 93-n, which is information about the actual video information 80 to be reproduced. The video information 91 is linked. These correspond to, for example, cells and video object information (VOBI) in the DVD recording standard.
[0051]
Thus, the original title information T1 (programs 93-1 to 9-n) has its own real video information, and this title is usually created during recording.
[0052]
On the other hand, some information is composed only of information for managing the reproduction order (reproduction order information). This is playlist information T2, for example, a playlist in the DVD recording standard. This playlist information T2 does not have its own real video information, and edits (deletes) the reference information 95-1 to 95-n linked to the real video information 91 of the original title information T1, as shown in FIG. , Add) to create a playlist.
[0053]
In the actual video information 91, time map information 92 is described. This time map information 92 designates a partial area 82 constituting the actual video information stream 81 corresponding to the actual video information 91. Links from the reference information 94-1 to n of the original title information T1 of the management information 90 or the reference information 95-1 to 95-n of the playlist information T2 to the actual video information 91 are specified by logical addresses. The link from the time map information 92 to the real video information stream 81 and its partial area 82 includes the number of the real video information stream 81, the number of partial areas 82 in the stream, the entry number for each partial area 82, individual This is performed based on the logical address to the partial area 82. With such a configuration, not only normal playback of recorded video information but also special playback such as double speed / slow playback and reverse playback, and scene search can be supported.
[0054]
<Operation of Video Information Processing Apparatus According to the Present Invention>
Hereinafter, the operation of the present invention will be described with reference to FIG. 3 and subsequent drawings. In the following description, the video information processing apparatus of the present invention is configured as follows.
[0055]
The features of the present invention are referred to as the first to eighth embodiments in the following description. Here, each embodiment will be briefly described in advance.
The first embodiment shows “when editing is performed using video / audio information being recorded”. Thus, it is possible to create and edit a playlist that refers to an already recorded part of the original title that is being recorded on the recording medium without waiting for the end of the recording process. Can be provided.
[0056]
The second embodiment shows “when a playlist used for editing is updated according to the progress of recording”. As a result, a playlist that refers to a part of the original title that is already being recorded, that has already been recorded on the recording medium, has been newly recorded, for example, by a timing such as re-editing or a call to a dedicated command. It becomes possible to reflect the continuation part.
[0057]
The third embodiment shows “when a playlist is specified without using unique information”. In other words, by limiting the number of playlists that can be created to refer to a recorded part of a title that is already being recorded on a recording medium to one, it is possible to use unique information outside the DVD recording standard. The playlist that reflects the progress of recording the original title can be specified.
[0058]
The fourth embodiment shows “when a playlist is specified using unique information”. In other words, by using unique information outside the DVD recording standard, it is possible to create a plurality of playlists that refer to recorded portions of a title that is currently being recorded on a recording medium, and to record the original title. A playlist that reflects the progress can be specified.
[0059]
The fifth embodiment shows “when the playlist is updated according to the progress of recording by rewriting the end of the playlist”. That is, by rejecting the editing process for the end of the playlist and rewriting the description at the end, the progress of recording the original title can be reflected in the playlist without using original information outside the DVD recording standard. it can.
[0060]
In the sixth embodiment, “when recording progress is inserted into a playlist as a new cell” is shown. In other words, by reflecting the part that has not yet been reflected in the playlist as new reference information in the playlist, it is possible to edit the end of the playlist while reflecting the progress of recording the original title in the playlist. can do.
[0061]
The seventh embodiment shows “when the insertion position is not specified and a new cell is inserted into the playlist”. In other words, when reflecting a part that has not yet been reflected in the playlist as new reference information in the playlist, it can be placed at a fixed position such as the end or the top of the playlist without using unique information outside the DVD recording standard. New reference information can be inserted.
[0062]
The eighth embodiment shows “when the insertion position is specified and a new cell is inserted into the playlist”. That is, when reflecting a part that has not yet been reflected in the playlist as new reference information to the playlist, by using unique information outside the DVD recording standard, new reference information can be placed at any position in the playlist. Can be inserted. This is the insertion of a new cell for recording progress at an arbitrary position by using special insertion position information. Means the form to be reflected in front of it.
[0063]
First, it is assumed that the video information processing apparatus of the present invention is a DVD recorder based on the DVD recording standard (DVD-VR standard). Further, it is assumed that the recording device is a hybrid recorder having two recording media of DVD and HDD, and video information can be dubbed between the DVD and HDD. In addition to having a function of recording to a DVD-RAM or the like based on the DVD-VR standard, recording to a DVD has a function of recording to a DVD-R based on the DVD video standard (DVD-Video standard). And
[0064]
(First embodiment)
Here, in the case of “editing using video / audio information being recorded” which is the first embodiment, the title having actual video and audio information is a DVD-VR standard program, It is assumed that a virtual title consisting only of reference information with respect to actual information on a recording medium is a DVD-VR standard playlist. This program is sometimes called an original title. The management information portion of the program (original title), which is information for managing the reproduction order (reproduction order information), and the playlist include reference information linked to the actual video information. This reference information is assumed to be a cell of the DVD-VR standard. The actual video information is assumed to be DVD-VR standard video object information (VOBI).
[0065]
Although not shown in FIG. 2, the management information portion of the program (original title), which is information for managing the playback order (playback order information), and the play list include a partial area called a chapter. It can be defined. An entry point of the DVD-VR standard is given as marking information at a position indicating the chapter boundary. That is, a position where an entry point is hit is defined as a chapter boundary, and a range from the position of one entry point to the next entry point is referred to as a chapter. However, since it is obvious that the first chapter in the title starts from the start position of the title, there may be an entry point at the front boundary position of chapter 1, that is, at the start position of the title. , May not exist.
[0066]
FIG. 3 is a diagram showing a relationship diagram between management information and actual video information, which is a concept of one embodiment of the present invention. FIG. 3 shows the relationship between the management information and the real video information as in FIG. 2 above, but the description of the subordinate information from the real video information stream is omitted.
[0067]
Here, it is assumed that recording of an original title “program #A” is currently in progress. This program #A includes “reference information #a” which is a cell of the DVD-VR standard. “Real video information # α” linked to the reference information #a is VOBI of the DVD-VR standard. The description of the time map information included in the actual video information # α is updated according to the recording progress of the actual video information stream to the recording medium, and the description of the end time information of the linked reference information #a is also updated.
[0068]
In the video information processing apparatus and video information processing method of the present invention, a playlist reflecting the contents of the program #A can be created while the recording of the program #A is in progress. “Playlist #B” in FIG. 3 is a playlist created while recording of program #A is in progress, and cell “reference information # 1” included in playlist #B is VOBI of program #A “ Reference is made to real image information # α ”.
[0069]
Here, even after the playlist #B is created and edited, the recording of the program #A proceeds, and the progress of the recording is, for example, at the timing of re-editing the playlist #B. Is reflected in playlist #B. This mechanism will be described in detail below in an embodiment using FIG.
[0070]
FIGS. 4 to 15 are flowcharts showing a process for creating a new playlist reflecting the contents of the original title while the recording of the original title is in progress.
[0071]
That is, a playlist that reflects the contents of the original title that is being recorded is created by the method described in the present invention, and the progress of the new recording is reflected in the playlist, and further edited in the playlist. These flowcharts show cases where various processes are performed.
[0072]
FIG. 4 is a flowchart of processing for newly creating a playlist that reflects the contents of the original title while recording the original title. FIG. 4 corresponds to the first embodiment, in which the first title described here corresponds to the original title, and the virtual second title corresponds to the playlist.
[0073]
Hereinafter, each step of the flowchart of FIG. 4 will be described.
[0074]
In step S11, the number of the original title that is currently being recorded is acquired. This is used to insert the original title as a part into the playlist.
[0075]
In step S12, time information # T1 of the VOBI time map when the recording of the original title in progress of recording to the recording medium is started is acquired. This corresponds to time information of the start point of the original title cell.
[0076]
In subsequent step S13, VOBI time map time information # T2 indicating that the original title has been recorded on the recording medium at the present time is acquired. At this time, the time information of the end point of the original title cell corresponds to this, but the recording is in progress during the processing of the subsequent steps, and the end point of the original title cell is sequentially continued until the recording process is completed. The time information will be updated.
[0077]
In the next step S14, a playlist for reflecting the contents of the original title during recording is created. Here, it is still in the form of securing a playlist as a container. The contents of step S14 will be described later with reference to the flowchart of FIG. 6 in the third embodiment and the flowchart of FIG. 7 in the fourth embodiment.
[0078]
If an error occurs in this step S14, in the subsequent step S15, all the subsequent steps S16 and thereafter are branched in a direction to skip, and the process is terminated. On the other hand, if the process of step S14 is normally completed, the process branches in a direction to proceed to the next step S16 in step S15.
[0079]
In step S16, a cell that refers to the previously acquired time information # T1 to # T2 is configured, and this cell is registered in the playlist as a container created in step S14. As a result, a playlist is created that reflects the portion of the original title that is being recorded that has already been recorded on the recording medium. Note that step S16 will be described later using the flowchart of FIG. 15 when the eighth embodiment is shown.
[0080]
Steps up to step S16 correspond to steps for creating a playlist that reflects the content of the recording ongoing title described in the first embodiment. The subsequent step S17 and subsequent steps correspond to steps for editing the playlist.
[0081]
If no editing process is performed on the playlist created by the process up to step S16, the process branches to step S19, skipping step S18 for performing the edit process, and proceeds to step S19. When editing a playlist, the process branches in the direction to proceed to step S18.
[0082]
In step S18, various editing processes are performed on the playlist that reflects the contents of the original title that is created by the above-described recording process. Examples of the editing processing performed here include chapter boundary setting (chapter division), chapter boundary deletion (chapter combination), registration of new parts to the playlist, and deletion of parts from the playlist. Is given as an example. Of course, it is not necessary to be able to perform all of the editing processes described here, and it is needless to say that editing processes other than those described here can also be performed. In addition, about this step S18, the process in the case of 5th Embodiment is later mentioned using the flowchart of FIG.
[0083]
When the editing process for the playlist is repeatedly executed, the process branches back to step S17 in the subsequent step S19, and the editing process is executed again. When the playlist editing is to be ended, the process branches in the direction to proceed to step S20.
[0084]
In step S20, the playlist reflecting the contents of the original title being recorded, which has been edited, is stored, and the series of processing ends.
[0085]
(Second Embodiment)
Next, FIG. 5 is a flowchart for explaining the process of updating the playlist created in the flowchart of FIG. 4 according to the recording progress state according to the second embodiment. Here, the first title described here corresponds to the original title, and the virtual second title corresponds to the play list.
[0086]
Hereinafter, each step of the flowchart of FIG. 5 will be described.
[0087]
In step S31, the number of the original title currently being recorded is acquired. This is used to insert the recording progress of the original title as a part into the playlist.
[0088]
In step S32, the playlist number that reflects the contents of the original title whose recording is in progress is acquired. This is to determine the re-edit target. The contents of step S32 will be described later using the flowchart of FIG. 8 when showing the third embodiment and the flowchart of FIG. 9 when showing the fourth embodiment.
[0089]
If an error occurs in this step S32, in the following step S33, all the subsequent steps S34 and after are branched in a direction to skip, and the process is terminated. On the other hand, when the process of step S32 is normally completed, the process branches in a direction to proceed to the next step S34 in step S33.
[0090]
In the subsequent step S34, VOBI time map time information # T3 indicating that the recording of the original title being recorded is currently recorded on the recording medium is acquired. At this time, the time information of the end point of the original title cell corresponds to this, but the recording is in progress during the processing of the subsequent steps, and the end point of the original title cell is sequentially continued until the recording process is completed. The time information will be updated.
[0091]
In the next step S35, the range from # T2 that has been recorded on the recording medium when the playlist was created last time according to the flowchart shown in FIG. 4 to # T3 acquired in step S34, that is, a new recording is performed. Is reflected in the playlist to be re-edited determined in step S32. Regarding the contents of this step S35, in the case of “if the playlist is updated according to the progress of recording by rewriting the end of the playlist” in the fifth embodiment, the flowchart of FIG. A case of “inserting the progress of recording into a playlist as a new cell” will be described later with reference to the flowchart of FIG.
In addition to these two cases, there are many methods for reflecting the progress of recording in the playlist, and all of them are included in the present invention. For example, it is preferable that the timing to be reflected is determined when the playlist to be re-edited is confirmed and the playlist editing operation screen is opened. Furthermore, for example, it is preferable to reflect the progress of recording in the playlist at predetermined time intervals such as every 5 minutes.
[0092]
Up to step S35 corresponds to the step of reflecting the recording progress state of the recording in progress title described in the second embodiment in the playlist. The subsequent steps S36 and subsequent steps correspond to steps for re-editing the playlist.
[0093]
If no editing process is performed on the playlist that reflects the recording progress state by the process up to step S35, the process branches to step S38 in step S36 so that step S37 in which the edit process is performed is skipped. move on. When editing a playlist, the process branches in a direction to proceed to step S37.
[0094]
In step S37, various editing processes are performed on the playlist reflecting the recording progress state by the above process. Examples of the editing processing performed here include chapter boundary setting (chapter division), chapter boundary deletion (chapter combination), registration of new parts to the playlist, and deletion of parts from the playlist. Is given as an example. Of course, it is not necessary to be able to perform all of the editing processes described here, and it is needless to say that editing processes other than those described here can also be performed. This step S37 will be described later with reference to the flowchart of FIG. 10 in the fifth embodiment, which is the case where the playlist is updated according to the recording progress by rewriting the end of the playlist. To do.
[0095]
When the editing process for the playlist is repeatedly executed, the process branches back to step S36 in the subsequent step S38, and the editing process is executed again. When the playlist editing is to be ended, the process branches in the direction of proceeding to step S39.
[0096]
In step S39, the playlist reflecting the recording progress state, which has been the object of editing so far, is saved, and the series of processing ends.
[0097]
(Third embodiment)
FIG. 6 is a third embodiment of the step S14 for creating a new playlist reflecting the contents of the original title whose recording is in progress in FIG. 19 is a flowchart illustrating a case where a play list is specified.
[0098]
Here, first, in step S41, it is determined whether or not there is already a playlist that reflects the contents of the original title whose recording is in progress. When the third embodiment is applied, only one such playlist can be created. Therefore, in this case, it is preferable to make a determination based on whether or not all the playlists that currently exist include cells that refer to the VOBI of the original title that is currently being recorded. .
[0099]
If it is determined in step S41 that there is already a playlist that reflects the content of the original title that is being recorded, the process branches to step S43. In step S43, an error code indicating that such a playlist can no longer be created is set, and the series of processing ends.
[0100]
On the other hand, if it is determined in step S41 that there is no playlist that reflects the contents of the original title whose recording is in progress, the process branches to step S42. In step S42, a new playlist is newly created, and the series of processes is terminated.
[0101]
In this way, by applying the third embodiment and limiting the creation of a playlist that reflects the contents of the original title that is being recorded, the recording can be performed without requiring special information. It is possible to create a playlist that reflects the contents of the ongoing original title.
[0102]
(Fourth embodiment)
FIG. 7 shows a fourth embodiment in which “use unique information” is used in step S14 for creating a new playlist reflecting the contents of the original title whose recording is in progress in FIG. Is a flowchart showing “when a playlist is specified”.
[0103]
Here, first, in step S44, it is determined whether or not there is already a playlist associated with the contents of the original title whose recording is in progress. When the fourth embodiment is applied, it is possible to create a plurality of playlists that refer to an original title that is being recorded, but the number of playlists that reflects the progress of recording is limited to one. . Therefore, in this case, it is preferable to determine whether or not there is a playlist that is associated with the original title as a playlist that reflects the recording progress state.
[0104]
If it is determined in step S44 that there is already a playlist associated with the original title, the process branches to step S47. In step S47, an error code indicating that such a playlist can no longer be created is set, and the series of processing ends.
[0105]
On the other hand, if it is determined in step S44 that there is no playlist associated with the original title, the process branches to step S45. In step S45, a new playlist is newly created.
[0106]
In the subsequent step S46, the newly created playlist is associated with the original title that is currently being recorded as a playlist reflecting the progress of the recording, the information is retained, and a series of processing is performed. finish.
[0107]
As described above, by applying the fourth embodiment and using special information for associating the original title with the playlist, it is possible to create a plurality of playlists that refer to the original title whose recording is in progress. In addition, it is possible to reliably correspond to a playlist that reflects the progress of recording.
[0108]
FIG. 7 is a flowchart for creating a playlist that reflects the progress of recording. In the case of creating a playlist that does not reflect the progress of recording and simply refers to the recorded part of the original title being recorded on the recording medium, the processing in steps S44 and S46 in FIG. Needless to say, it becomes unnecessary.
[0109]
FIG. 8 shows the third embodiment, in which “unique information is obtained” in step S32 for obtaining the playlist number that reflects the recording progress of the original title recording in FIG. 5 described above. It is a flowchart which shows a case where a play list is specified without being used.
[0110]
Here, first, in step S48, it is determined whether or not there are a plurality of playlists reflecting the contents of the original title whose recording is in progress. When the third embodiment is applied, only one such playlist can be created. Therefore, in this case, it is preferable to make a determination based on whether or not there are a plurality of cells that refer to the VOBI of the original title that is currently being recorded among all the playlists that currently exist. is there.
[0111]
If it is determined in step S48 that there are a plurality of playlists reflecting the contents of the original title whose recording is in progress, the process branches to step S51. In step S51, an error code indicating that the target playlist number cannot be acquired is set, and the series of processing ends.
[0112]
On the other hand, if it is determined in step S48 that there are not a plurality of playlists reflecting the contents of the original title whose recording is in progress, the process branches to step S49.
[0113]
In step S49, it is determined whether or not there is a playlist that reflects the contents of the original title whose recording is in progress. When the third embodiment is applied, only one such playlist can be created. Therefore, in this case, it is preferable to make a determination based on whether or not all the playlists that currently exist include cells that refer to the VOBI of the original title that is currently being recorded. .
[0114]
If it is determined in step S49 that there is no playlist reflecting the contents of the original title whose recording is in progress, the process branches to step S51. In step S51, an error code indicating that the target playlist number cannot be acquired is set, and the series of processing ends.
[0115]
On the other hand, if it is determined in step S49 that there is a playlist that reflects the contents of the original title whose recording is in progress, the process branches to step S50.
[0116]
When step S50 is reached, it means that there is only one playlist including a cell that refers to the VOBI of the original title that is currently being recorded. Therefore, in step S50, the playlist number is acquired as the playlist number reflecting the progress of recording of the original title whose recording is in progress, and the series of processing ends.
[0117]
In this way, by applying the third embodiment and limiting the creation of a playlist that reflects the contents of the original title whose recording is in progress, recording can be performed without requiring special information. It is possible to acquire a playlist number that reflects the progress of the recording of the ongoing original title.
[0118]
FIG. 9 shows a fourth embodiment, in which “play using unique information is performed” in step S32 for obtaining the playlist number reflecting the recording progress of the recording of the original title in progress in FIG. It is a flowchart which shows a case where a list is specified.
[0119]
Here, first, in step S52, it is determined whether or not there is a playlist reflecting the contents of the original title whose recording is in progress. When the fourth embodiment is applied, a plurality of such playlists can be created. However, if there is no such playlist in the first place, there is no need to perform subsequent processing. In this case, it is preferable to make a determination based on whether or not all the playlists that currently exist include a cell that refers to the VOBI of the original title that is currently being recorded.
[0120]
If it is determined in step S52 that there is no playlist reflecting the contents of the original title whose recording is in progress, the process branches to step S55. In step S55, an error code indicating that the target playlist number cannot be acquired is set, and the series of processing ends.
[0121]
On the other hand, if it is determined in step S52 that there is a playlist reflecting the contents of the original title whose recording is in progress, the process branches to step S53.
[0122]
In step S53, it is determined whether there is a playlist associated with the original title whose recording is in progress. When the fourth embodiment is applied, it is possible to create a plurality of playlists that refer to an original title that is being recorded, but the number of playlists that reflects the progress of recording is limited to one. . Therefore, in this case, it is preferable to check the contents described in the special information and specify the target playlist.
[0123]
If it is determined in step S53 that the playlist number associated with the original title cannot be acquired, for example, there is no description of the association information because no such playlist exists. However, if there is an invalid description that points to a non-existing playlist, the process branches to step S55. In step S55, an error code indicating that the target playlist number cannot be acquired is set, and the series of processing ends.
[0124]
On the other hand, if it is determined in step S53 that the playlist number associated with the original title can be acquired, the process branches to step S54.
[0125]
When step S54 is reached, there is a playlist associated with the original title. Therefore, the playlist number is acquired as the playlist number reflecting the recording progress status of the original title whose recording is in progress, and the series of processing ends.
[0126]
As described above, by applying the fourth embodiment and using special information for associating the original title with the playlist, it is possible to create a plurality of playlists that refer to the original title whose recording is in progress. In addition, it is possible to acquire a playlist number that reflects the progress of recording.
[0127]
(Fifth embodiment)
FIG. 10 shows a fifth embodiment in which step S18 in FIG. 4 and step S37 in FIG. 5 are steps for performing an editing process on the playlist that reflects the contents of the original title whose recording is in progress. 19 is a flowchart illustrating a case where the playlist is updated according to the progress of recording by rewriting the end of the playlist.
[0128]
Here, first, in step S61, the content of the editing process to be performed on the playlist is determined.
[0129]
In step S61, if the editing process to be performed on the playlist is either the deletion of the chapter at the end of the playlist title or the part registration at the end of the playlist, the process branches to step S63. To do. In step S63, these two editing processes are rejected, and the series of processes is terminated.
[0130]
On the other hand, if the editing process to be performed on the playlist is other than the two editing processes in step S61, the process branches to step S62. In step S62, the editing process for the playlist is executed, and the series of processes is terminated.
[0131]
In this way, by applying the fifth embodiment, it is possible to continue to hold the last cell of the playlist at the time of starting playlist editing and the end time information of the cell. Specifically, for example, in the flowchart of FIG. 4, it is possible to continue to hold # T2, which is time information of the time map of VOBI where the recording on the recording medium has been completed. As a result, it is possible to reflect the recording progress state by rewriting the end time information at the end of the playlist. In the above example, the value of # T2 is rewritten.
[0132]
FIG. 11 shows the fifth embodiment, which is a step for newly reflecting the recording progress state in the play list reflecting the contents of the original title whose recording is in progress. 19 is a flowchart illustrating a case where a playlist is updated according to the progress of recording by rewriting the end of the list.
[0133]
Here, first, in step S64, the last cell of the target playlist is specified as a processing target. The cell at the end of the playlist continues to hold the cell at the end of the title and the end time information of the cell when the playlist was last edited according to the flowchart described above with reference to FIG. Specifically, in the flowchart of FIG. 4, for example, # T2 that is time information of the time map of VOBI where the recording on the recording medium has been continued is held.
[0134]
In step S65, the end time information of the target cell is rewritten. Specifically, in the flowchart of FIG. 5, for example, the value of # T2 is rewritten to # T3, which is time information of the VOBI time map where recording has newly proceeded. After the rewriting is completed, the series of processing ends.
[0135]
In this way, by applying the fifth embodiment, it is possible to reflect the recording progress state in such a manner that the end time of the last cell in the playlist that has been rejected and held in the editing process is rewritten.
[0136]
(Sixth embodiment)
FIG. 12 shows “recording” in step S35 of FIG. 5 which is a step of newly reflecting the recording progress state in the playlist reflecting the contents of the original title whose recording is in progress, which is the sixth embodiment. Is a flow chart showing a case where the progress of is inserted into a playlist as a new cell.
[0137]
Here, first, in step S66, a cell that covers the progress of recording is newly constructed. Specifically, for example, in the flowchart of FIG. 4, # T2 that is the time information of the time map of VOBI where the recording on the recording medium has been completed is the starting point, and the recording has subsequently progressed in the flowchart of FIG. A cell is newly constructed such that # T3, which is time information in the time map of VOBI, is the end point.
[0138]
In step S67, the newly configured cell is inserted into the playlist. The contents of step S67 will be described later using the flowchart of FIG. 13 for the process when the seventh embodiment is applied, and the flowchart of FIG. 14 for the process when the eighth embodiment is applied. .
[0139]
In this way, by applying the sixth embodiment, even if the last cell of the playlist or the end time information of the cell is not retained by the editing process, a new cell is configured and inserted into the playlist. It is possible to reflect the progress of recording in the form.
[0140]
(Seventh embodiment)
FIG. 13 is a step of reflecting the progress of recording as a new cell in the playlist, which is the seventh embodiment, with respect to step S67 of FIG. It is a flowchart which shows a case where it inserts.
[0141]
Here, in step S68, a new cell that covers the progress of recording is inserted at a fixed position on the playlist. This insertion position is determined as the product specification of the video information processing apparatus of the present invention. For example, the insertion position is always inserted at the end of the playlist, or is always inserted at the beginning of the playlist.
[0142]
As described above, by applying the seventh embodiment, even if the last cell of the playlist or the end time information of the cell is not retained by the editing process, a new cell is configured and a special cell is created. It is possible to reflect the recording progress state by inserting it at a fixed position in the playlist without using information.
[0143]
(Eighth embodiment)
FIG. 14 is a step of reflecting the progress of recording in the eighth embodiment as a new cell in the playlist. In step S67 of FIG. 12, “specify the insertion position and make the new cell into the playlist. It is a flowchart which shows a case where it inserts.
[0144]
Here, first, in step S69, position information on the playlist for inserting a new cell is acquired. A process for setting the position information prior to this process will be described later with reference to FIG.
[0145]
In step S70, a new cell that covers the progress of recording is inserted at the insertion position on the playlist from which the position information has been acquired.
[0146]
In this way, by applying the eighth embodiment, even if the last cell of the playlist or the end time information of the cell is not retained by the editing process, a new cell is configured and a special cell is created. By using the information, it is possible to reflect the progress of recording in such a way that the insertion position in the playlist has a certain degree of freedom.
[0147]
FIG. 15 is a process for setting the position information of the insertion position acquired in step S69 of FIG. 14, which is performed prior to the process of inserting the progress of recording into the playlist as a new cell according to the flowchart described in FIG. It is a flowchart explaining about. The flowchart of FIG. 15 shows the information on the insertion position in the playlist in the processing contents of step S16 in FIG. 4 and step S35 in FIG. 5 when the contents described in the sixth embodiment and the eighth embodiment are applied. Is added to the process to set and hold.
[0148]
First, in step S71, the part already recorded on the recording medium is reflected in the playlist. This is because when the range from # T1 to # T2 is reflected in the playlist in step S16 of FIG. 4 described above, or from # T2 to # T3 which is the progress of recording in step S35 of FIG. This corresponds to reflecting the range in the playlist.
[0149]
Next, in step S72, the position immediately after the part reflecting the recorded part is held as insertion position information. Here, based on the idea of reflecting the progress of the new recording in the position after the time of the part that has already been recorded, the insertion position information is the position immediately after the recorded part, Needless to say, the insertion position is not restricted to this position.
[0150]
In this way, by using special information, it is possible to reflect the progress of recording in such a way that the insertion position in the playlist has a certain degree of freedom.
[0151]
From FIG. 16 to FIG. 32, the video information processing apparatus according to the present invention creates a playlist that reflects the contents of the original title that is being recorded, and also displays the new recording progress in the playlist. It is explanatory drawing explaining the transition of management information when various processes of reflecting and also performing edit processing to the play list are performed. Here, as an example, FIGS. 16 to 22 show cases of the video information processing apparatus to which the first to third embodiments and the fifth embodiment are applied.
[0152]
Further, FIGS. 23 to 32 show cases of the video information processing apparatus to which the first embodiment, the second embodiment, the fourth embodiment, the sixth embodiment, and the eighth embodiment are applied. Needless to say, combinations after the third embodiment are not limited to those shown here.
[0153]
<Transition of Management Information of Video Information Processing Device According to the Present Invention>
FIG. 16 to FIG. 22 are cases of the video information processing apparatus to which the first to third embodiments and the fifth embodiment are applied, and a playlist reflecting the contents of the original title that is being recorded. , The reflection of the progress of the new recording for the playlist, and the transition of the management information when the editing process is performed for the playlist. In this series of examples, the gist of the present invention can be achieved without using any special information.
[0154]
First, the explanatory diagram of FIG. 16 shows a state in which recording of an original title “program # A1” is in progress. “Reference information # a1” included in the program # A1 corresponds to a cell, in which chapter division is performed by editing processing performed during recording, and there are three chapters as shown in the figure. Yes. The reference information # a1 is linked to “real video information # α1” which is VOBI. The initial value of the time information of the VOBI time map is # T1, and it is assumed that the recording has progressed to the position where the time information of the VOBI time map is # T2.
[0155]
Next, FIG. 17 shows the creation of a playlist that reflects the portion of the program # A1 that has been recorded on the recording medium when the time information of the time map of the VOBI has reached # T2. Shows the state. Here, the newly created “playlist # B1” is a playlist that reflects the contents of the program # A1 during recording, and the cell “reference information # b1” included in this playlist # B1 is the program # A1. The range from # T1 to # T2 of VOBI of A1 is referenced. The reference information # b1 also inherits the three chapters included in the program # A1. During this time, the recording of the program # A1 is in progress, and although it is very short, it takes a certain amount of time to create a playlist. Therefore, the recording of the program # A1 actually starts from the position of # T2 at this time. It is progressing but omitted here.
[0156]
Here, the third embodiment is applied, and a playlist reflecting the contents of the program # A1 in which recording is in progress is limited to this playlist # B1 only. Therefore, no other playlist that reflects the contents of the program # A1 can be created until the recording process is completed.
[0157]
FIG. 18 shows a state where the editing process is performed on the playlist # B1. Here, an example is shown in which chapter # 3 of playlist # B1 is further divided into chapters, and playlist # B1 includes four chapters. At this time, the recording of the program # A1 further proceeds from the position of # T2.
[0158]
FIG. 19 shows a state where the playlist # B1 is further edited. Here, an example is shown in which chapter # 2 of playlist # B1 is deleted, and the original chapter numbers # 3 and # 4 are moved up to numbers # 2 and # 3, respectively. In addition, the cell included in the playlist # B1 is divided into two for the process of deleting the middle of the cell. The cell in the first half is newly “reference information # b1”, and the cell in the second half is “reference information # b2”. In addition, the area on VOBI that was referred to by the deleted original chapter 2 is not referred to from the playlist # B1 due to this chapter deletion. At this point, recording of program # A1 is still in progress.
[0159]
Here, the fifth embodiment is applied, and deletion of the last chapter 3 of the playlist # B1 and registration of parts after chapter 3 are rejected.
[0160]
FIG. 20 shows a state in which the editing process for the playlist # B1 is closed and a while has passed. At this time, the recording of the program # A1 is further advanced to the position of # T3.
[0161]
FIG. 21 shows a state in which the progress of the new recording of the program # A1 is reflected in the playlist # B1 when the recording progresses until the time information of the time map of this VOBI is # T3. . Here, the fifth embodiment is applied, and the end time of the reference information # b2, which is the last cell of the playlist # B1, is rewritten from # T2 to # T3, from # T2, which is the progress of the new recording. The range up to # T3 is reflected in the playlist # B1. During this time, the recording of the program # A1 is in progress, and although it is very short, it takes a certain amount of time to rewrite the time information at the end of the reference information # b2. At that time, it further progresses from the position of # T3, but it is omitted here.
[0162]
FIG. 22 shows a state where the playlist # B1 is re-edited. Here, an example is shown in which parts that refer to other original titles are registered between chapters 2 and 3 of playlist # B1. At this time, the recording of the program # A1 further proceeds from the position of # T3.
[0163]
Thereafter, the recording progress status can be reflected in the playlist # B1 and editing can be performed in the same manner.
[0164]
FIGS. 23 to 32 show cases of the video information processing apparatus to which the first embodiment, the second embodiment, the fourth embodiment, the sixth embodiment, and the eighth embodiment are applied, and recording is in progress. Explains the creation of a playlist that reflects the contents of the original title, the reflection of the progress of the new recording for the playlist, and the transition of management information when editing processing is performed for the playlist. .
[0165]
In this series of examples, by using special information together, it is possible to achieve the gist of the present invention while increasing the degree of freedom by eliminating restrictions on editing operations and creating playlists.
[0166]
First, FIG. 23 shows a state in which recording of an original title “program # A2” is in progress. “Reference information # a2” included in the program # A2 corresponds to a cell, in which chapter division is performed by editing processing performed during recording, and there are two chapters as shown in the figure. Yes. The reference information # a2 is linked to “real video information # α2” which is VOBI. It is assumed that the initial value of the time information of the VOBI time map is # T1, and at the time shown in FIG. 23, recording is progressing to the position where the time information of the VOBI time map is # T2.
[0167]
Next, FIG. 24 shows the creation of a playlist that reflects the portion of the program # A2 that has already been recorded on the recording medium when the recording has progressed to the time information in the time map of VOBI # T2. Shows the state. Here, the newly created “playlist # C1” is a playlist that reflects the contents of the program # A2 in progress of recording, and the cell “reference information # c1” included in the playlist # C1 is the program #A. The range from # T1 to # T2 of VOBI of A2 is referred to. The reference information # c1 also inherits two chapters included in the program # A2. During this time, the recording of the program # A2 is progressing, and although it is very short, it takes a certain amount of time to create the playlist. Therefore, the recording of the program # A2 is actually further started from the position of # T2 at this time. It is progressing but omitted here.
[0168]
Next, FIG. 25 shows a state in which various processes are performed based on the application of the fourth and eighth embodiments. Here, according to the fourth embodiment, information for associating the program # A2 in progress of recording with the playlist # C1 reflecting this content is described and held. Further, by applying the eighth embodiment, here, the position immediately after the reference information # c1 of the playlist # C1 is held as the cell insertion position when reflecting the recording progress. During this time, the recording of the program # A2 is in progress, but since the time is very short, the illustration of the progress state is omitted here.
[0169]
FIG. 26 shows a state where the editing process is performed on the playlist # C1. Here, an example is shown in which chapter # 2 of playlist # C1 is further divided into chapters, and the playlist # C1 includes three chapters. At this time, the recording of the program # A2 further proceeds from the position of # T2.
[0170]
FIG. 27 shows a state where the playlist # C1 has been further edited. Here, an example is shown in which chapter # 3 of playlist # C1 is deleted. Here, unlike the case where the third embodiment and the fifth embodiment described above with reference to FIGS. 16 to 22 are applied, the end of the playlist # C1 that refers to the position of # T2 is used. Information is lost. However, in this example, according to the contents of the eighth embodiment, there is information on the position where the cell reflecting the progress of the recording is inserted, and it is shifted forward by the deleted amount of chapter 3 and immediately after chapter 2. The position is held as insertion position information. At this point, recording of program # A2 is still in progress.
[0171]
FIG. 28 shows a state in which the editing process for the playlist # C1 is closed and a while has passed. At this point, recording of program # A2 is further in progress.
[0172]
FIG. 29 shows a state where a new “playlist D1” that refers to the contents of the program # A2 during recording is created. Here, unlike the case where the third embodiment and the fifth embodiment described above with reference to FIGS. 16 to 22 are applied, a plurality of playlists that refer to the original title during recording are created. Is possible. However, by applying the contents of the fourth embodiment, the playlist that reflects the recording progress state can be identified as “playlist # C1”. At this point, the recording of program # A2 is still in progress.
[0173]
FIG. 30 shows a state in which editing of the new playlist D1 referring to the content of the program # A2 in progress of recording is closed and a while has passed. At this point, the recording of program # A2 has progressed to the position of # T3.
[0174]
FIG. 31 shows a state in which the progress of the new recording of the program # A2 is reflected in the playlist # C1 when the recording progresses to the time information of the time map of this VOBI at # T3. . Here, the sixth embodiment is applied, a new cell “reference information # c2” that refers to the range from # T2 to # T3 is configured, and this cell is inserted into the playlist # C1 for new recording. The range from # T2 to # T3, which is the amount of progress, is reflected in the playlist # C1. At that time, the reference information # c2 is inserted at the insertion position held in advance by the eighth embodiment. The range of the reference information # c2 inserted here is chapter # 3 on the playlist # C1. In addition, when this reference information # c2 is inserted, the cell insertion position when the recording progress state is reflected again next time is newly set immediately after the reference information # c2. Note that the playlist that reflects the progress of the recording is specified as “playlist # C1” based on the association information that has been held in advance by applying the fourth embodiment. While these processes are being performed, the recording of the program # A2 is progressing. Actually, the recording of the program # A2 is proceeding further from the position of # T3 at this point, but it is omitted here. Yes.
[0175]
FIG. 32 shows a state where the playlist # C1 has been re-edited. Here, an example is shown in which chapter # 3 of playlist # C1 is further divided into chapters, and the playlist # C1 includes four chapters. At this time, the recording of the program # A2 further proceeds from the position of # T3.
[0176]
Thereafter, the recording progress status can be reflected on the playlist # C1 and editing can be performed in the same manner.
[0177]
As mentioned above, although embodiment of this invention was described using drawing, this invention is not limited to what was described here, It cannot be overemphasized that various forms can be taken within the range which does not deviate from the main point. Yes.
[0178]
For example, in the embodiment described with reference to FIGS. 23 to 32, the video information obtained by applying the characteristics of the fourth embodiment, the sixth embodiment, and the eighth embodiment to the first embodiment and the second embodiment. A processing device is shown. However, this applies the features of the fourth embodiment, the sixth embodiment, and the seventh embodiment to the first embodiment and the second embodiment, and the cell that refers to the recording progress is set as the set specification of the apparatus. It is also preferable to insert it at a set fixed position (for example, always at the end of the playlist).
[0179]
Further, the content further applied to the first embodiment and the second embodiment may be a combination of the features of the fourth embodiment and the fifth embodiment.
[0180]
Further, the content further applied to the first embodiment and the second embodiment may be a combination of the features of the third embodiment, the sixth embodiment, the seventh embodiment, or the eighth embodiment. In this case, depending on the editing process for the playlist that reflects the contents of the original title that is being recorded, there is a possibility that the cell that refers to the VOBI of the original title that is being recorded does not exist on the playlist. In this case, the present invention may be applied under the condition that such a cell exists on the playlist. At this time, if necessary, a mechanism may be provided to warn the user by displaying an alert that the editing progress may not be reflected in the playlist. Or a function to apply such an editing restriction that such a cell always exists on the playlist (a chapter including the last cell referring to the original title in progress of recording rejects deletion, etc.) It is also possible to adopt a mechanism in which the correspondence between the original title that is being recorded and the playlist that reflects the progress of the recording is always kept.
[0181]
In addition, an editing process for deleting the playlist itself from the playlist reflecting the progress of recording is also an option. In that case, for example, such a form may be adopted that such processing is rejected in step S61 of FIG. Alternatively, a new playlist that reflects the progress of recording may be newly created. In that case, it may be in the form of creating a playlist that reflects all of the recorded part of the original title that is already recorded on the recording medium from the beginning, or to the playlist that was deleted earlier. The reflected part may not be reflected in the new playlist, but may be reflected in the new playlist during the recording.
[0182]
Further, in the above-described embodiment, the timing for reflecting the recording progress state is performed on the playlist reflecting the contents of the original title during the recording at the timing of re-editing the playlist. However, the reflection of the progress of recording is not necessarily integrated with the re-editing of the playlist. For example, in the flowchart of FIG. 5, the video information processing apparatus of the present invention may further include only reflecting the recording progress state in which steps S <b> 36 to S <b> 38 are omitted. Similarly, when a new playlist that reflects the contents of the original title that is being recorded is created, it is not necessarily integrated with the editing process for the playlist. For example, steps S17 to S19 in FIG. The video information processing apparatus according to the present invention may further include omitting the creation of a new playlist only.
[0183]
【The invention's effect】
As described above in detail, according to the present invention, without waiting for the end of the recording process, a playlist that refers to a part already recorded on the recording medium of the original title being recorded is created and edited. Therefore, it is possible to provide a video information processing apparatus and method that can be used.
