In the present embodiment, the signal processing unit 20 is provided with a sound detection unit 25 . The audio data from the decoder 12 is also supplied to the audio detection unit 25 . The audio detection unit 25 serving as a recording reservation-related information acquisition unit analyzes the content of audio in the broadcast program by known audio recognition processing, natural language analysis processing, and the like. Based on the analysis result, the audio detection unit 25 determines whether or not the program currently being broadcast is a broadcast preview program that previews the broadcast of a program scheduled to be broadcast in the future (hereinafter, referred to as a scheduled broadcast program). When it is determined that the program currently being broadcast is a broadcast preview program, the audio detection unit 25 performs information necessary for the recording reservation of the broadcast scheduled program among the contents of the broadcast preview program (hereinafter, referred to as recording reservation related information). Collected, the collected information about the recording reservation is supplied to the recording unit 26 and recorded together with the current time information. The recording unit 26 includes a predetermined recording medium such as a hard disk and a storage medium.

For example, as the information related to the recording reservation, the broadcast channel on which the scheduled program is broadcast, the broadcast start date and time, the broadcast end date and time information, and the like are considered. For example, if the sound detection unit 25 detects that the sound of a program being broadcast contains words such as "Broadcast at 0:00 on October 0", "Broadcast at 0:00 tonight", etc., the sound detection unit 25 determines the broadcast start date and time based on these words and the current reception. The information of the channel is recorded in the recording unit 26 as the information about the recording reservation for the broadcast scheduled program. In addition, since the recording reservation is performed using the program table information, the information related to the recording reservation may be information that can specify the program to be reserved for recording from the program table information. Information about the program name of the broadcast scheduled program.

In addition, the sound detection unit 25 may detect “00,000,000 o’clock broadcast” and “Tonight . phrases such as “time broadcast”, these phrases are recorded in the recording unit 26 as information about the recording reservation. In addition, the sound detection unit 25 may store only the latest recording reservation-related information in the recording unit 26, and may store the recording reservation-related information for a predetermined period in the recording unit 26, and may store a predetermined number of recording reservations. The related information is stored in the recording unit 26 .

The control circuit 21 generates recording reservation information based on a normal recording reservation operation by a user of a future program whose program information is included in the program guide information recorded in the recording unit 26 . The recording reservation information in this case is generated by the control circuit 21 based on, for example, a user's recording reservation operation on the program table, and the control circuit 21 generates the recording reservation information using information necessary for reservation of recording in the program table information. The control circuit 21 records the generated recording reservation information in the recording unit 26 . Time information is supplied from the timer circuit 27 to the control circuit 21 . The control circuit 21 uses the time information from the timer circuit 27 to generate a recording instruction command based on the recorded recording reservation information, and outputs it to the recording processing unit 24 .

In the present embodiment, the control circuit 21 can perform a recording reservation operation for a user of a scheduled broadcast program whose program information does not include program information recorded in the recording unit 26 (hereinafter, referred to as a recording reservation operation based on a broadcast preview). Generate recording reservation information. In addition, by pre-assigning the recording reservation operation based on the broadcast notice to a predetermined key of the remote controller, the user can also perform the recording reservation operation based on the broadcast notice by one-touch operation.

That is, when the control circuit 21 is given the operation information corresponding to the recording reservation operation based on the broadcast advance notice, the input of the operation information is used as a trigger, and the information about the recording reservation recorded most recently before the input timing of the operation information is set to the The object of the recording reservation, that is, the recording reservation reservation information. For example, the control circuit 21 may set the recording reservation information by adding a flag indicating that it is the recording reservation information to the recording reservation related information recorded in the recording unit 26 .

In addition, considering the erroneous operation, when a predetermined period of time has elapsed from the last recording of the recording reservation-related information, and the recording reservation operation based on the broadcast notice is performed, the operation may be regarded as an erroneous operation, and the last recorded information may not be recorded. The recording reservation related information is set as the recording reservation reservation information. In addition, the user may be able to arbitrarily designate not only the recording reservation-related information previously recorded based on the recording reservation operation based on the broadcast notice, but also the recording-reservation-related information set to the recording reservation information.

The control circuit 21 judges whether or not the program information of the scheduled broadcast program is included in the recording unit 26 by comparing the information of the recording start date and time in the recording reservation related information set in the recording reservation information and the time information from the timer circuit 27 . If the program table information recorded in the program table information is included in the program table information, the program information of the scheduled broadcast program is acquired from the program table information based on the recording reservation related information, and the recording reservation information is generated based on the acquired information and recorded in the recording unit 26. The control circuit 21 refers to the recording reservation information, and when the time information from the timer circuit 27 detects that the scheduled recording start time is reached, generates a recording instruction command based on the recording reservation information, and outputs the generated recording instruction command to the recording processing unit 24 .

In addition, the control circuit 21 may search the program information of the program corresponding to the recording reservation-related information from the program table information every time the program table information recorded in the recording unit 26 is updated, and when the program information is retrieved, generate Recording reservation information.

In this case, even if the recording reservation related information set in the recording reservation information does not include the information of the recording start date and time but only the broadcast program name information, the recording reservation information can be recorded for the broadcast reservation program. generate.

In addition, the user can perform a recording reservation operation based on a broadcast notice through a remote controller (not shown), and also can perform a recording reservation operation based on a broadcast notice through a voice operation.

In addition, not only the control circuit 21 in the signal processing unit 20, but also each unit in the broadcast data receiving unit 10, each unit in the signal processing unit 20, and the output control unit 31 may include a processor using a CPU, an FPGA, or the like, and may include a processor using a CPU, an FPGA, or the like. A program stored in the illustrated memory operates and controls each part, and a part or all of the functions may be realized by an electronic circuit of hardware.

Next, the operation of the thus-configured embodiment will be described with reference to FIG. 2 . FIG. 2 is a flowchart for explaining the operation of the first embodiment.

The television broadcast signal (RF input) received through the antenna is input to the tuner 11 of the broadcast data receiving unit 10 . The tuner 11 is controlled by the control circuit 21 , selects a broadcast signal of a desired channel, and outputs the selected broadcast signal to the decoder 12 . The decoder 12 is controlled by the control circuit 21, demodulates the selected broadcast signal, and obtains a transport stream including a desired program. The decoder 12 performs TS decoding processing of the multiplexed transport stream (TS) signal, and obtains digital video data and audio data of a desired program. These video data and audio data are supplied to the signal processing unit 20 .

The video and audio processing unit 22 of the signal processing unit 20 performs predetermined digital signal processing on the digital video data supplied from the decoder 12 , and outputs it to the output control unit 31 . The output control unit 31 outputs the video signal to the display unit 32 and the audio signal to the audio output unit 33 . In this way, the video of the broadcast program is displayed on the display unit 32 , and the audio is outputted from the audio output unit 33 .

Further, the decoder 12 acquires additional information included in the digital broadcast and outputs it to the signal processing unit 20 . The program table management unit 23 of the signal processing unit 20 acquires program table information among the additional information, supplies the acquired program table information to the recording unit 26 and records it.

In the present embodiment, the audio data from the decoder 12 is also supplied to the audio detection unit 25 . In step S1 of FIG. 2 , the audio detection unit 25 analyzes the audio content in the broadcast program, and collects recording reservation-related information necessary for recording the scheduled broadcast program among the content of the broadcast preview program (CM). For example, when the audio detection unit 25 detects a phrase such as "broadcasting on channel 0 from 0:00, 00, 00, 00" from a program being broadcast, it acquires information about recording reservations such as channel 0 and 0:00,000,000. The sound detection unit 25 supplies the acquired information about the recording reservation to the recording unit 26 and records it. In the present embodiment, the audio detection unit 25 sequentially collects the recording reservation-related information during the reception of the broadcast signal, and records it in the recording unit 26 .

The control circuit 21 confirms the interruption from the user (S2). That is, the control circuit 21 confirms whether or not a recording reservation operation by the user has occurred based on the broadcast notice, based on the operation information from the remote controller receiving unit 41 and the audio receiving unit 42 . When no interruption occurs, the process returns to step S1, and steps S1 and S2 are repeated.

Here, the user watches the broadcast preview program in the broadcast, and wishes to reserve the recording of the scheduled broadcast program introduced in the broadcast preview program. In this case, the user operates a remote controller or the like to perform a recording reservation operation based on a broadcast notice. When the control circuit 21 receives the operation information based on the operation, the process proceeds to step S3, reads the latest information among the recording reservation-related information recorded in the recording unit 26, and acquires information such as broadcast start date and time. The control circuit 21 determines whether or not the program table information including the information of the program up to the acquired broadcast start date and time, that is, the acquired program information (target program information) of the program (broadcast scheduled program) of the acquired broadcast start date and time has been acquired. Included in the program table information (S4).

When the program information of the scheduled broadcast program specified by the information about the recording reservation is already included in the program table information, the control circuit 21 executes the recording reservation in step S5. That is, the program information for the broadcast scheduled program is acquired from the program table information, and the recording reservation information is generated.

Therefore, the user does not need to perform the operation of displaying the program list and selecting the scheduled broadcast program, and can perform the recording reservation of the scheduled broadcast program with a simple operation.

On the other hand, when the program table information including the program information of the scheduled broadcast program is not received at the broadcast time of the broadcast preview program, the control circuit 21 moves to step S6, and sets the recording reservation related information read in step S3 as The recording reservation schedule information is held in the recording unit 26 until the program table information including the program information (target program information) up to the broadcast start date and time of the broadcast schedule program is acquired. The control circuit 21 stands by during this period (S7). In addition, the control circuit 21 may determine the waiting period based on the time information from the timer circuit 27, or may perform a search process every time the program table information is acquired to determine the waiting period.

When the control circuit 21 acquires the program table information including the program information of the scheduled broadcast program, the control circuit 21 reads the recording reservation related information set in the recording reservation reservation information, and executes the recording reservation (S8). That is, the program information for the broadcast scheduled program is acquired from the program table information, and the recording reservation information is generated. The control circuit 21 refers to the recording reservation information and detects the scheduled recording start time according to the time information from the timer circuit 27 , generates a recording instruction command based on the recording reservation information, and outputs the generated recording instruction instruction to the recording processing unit 24 . When a recording instruction command is given from the control circuit 21, the recording processing unit 24 controls the recording of the program recording unit 35 according to the recording instruction command. In this way, reserved video recording of a program scheduled to be broadcast can be performed.

In this way, in the present embodiment, the recording reservation-related information necessary for the recording reservation of the broadcast scheduled program is automatically obtained and recorded from the broadcast preview program, and the recorded recording reservation-related information is automatically used according to the recording reservation operation based on the broadcast preview of the user. Execute the recording reservation. As a result, it is possible to accept a recording reservation operation before the information of the future program predicted by the broadcast is acquired as the program table information, and the convenience can be remarkably improved. That is, when the user wishes to watch the broadcast scheduled program introduced by the broadcast preview program, the user does not need to perform a search operation of the program table immediately, and can make a recording reservation through a simple recording reservation operation. In addition, it is also possible to make a recording reservation in advance for a future program for which the scheduled broadcast program does not exist in the program schedule and cannot be originally reserved for recording.

Second Embodiment

FIG. 3 is a block diagram showing a second embodiment. In FIG. 3 , the same reference numerals are given to the same components as those in FIG. 1 , and descriptions thereof are omitted.

The present embodiment differs from the first embodiment in that the information about the recording reservation is implemented by capturing a video.

In FIG. 3 , the signal processing unit 50 is different from the signal processing unit 20 of FIG. 1 in that a video analysis unit 51 is used instead of the audio detection unit 25 . The video data is supplied from the decoder 12 to the video analysis unit 51 of the signal processing unit 50 . The video analysis unit 51 serving as a recording reservation-related information acquisition unit may include a processor using a CPU, an FPGA, or the like, and may operate and control each unit according to a program stored in a memory (not shown), or may be electronically controlled by hardware. circuit to achieve part or all of the function. In addition, the video analysis unit 51 has a buffer circuit (not shown) that holds the video data from the decoder 12 for a predetermined period for analysis processing.

In the present embodiment, the control circuit 21 requests the video analysis unit 51 to perform analysis processing when an interruption occurs due to a recording reservation operation based on a broadcast notice performed by the user. For example, when a user wishes to reserve a recording of a broadcast scheduled program introduced by the broadcast scheduled program, the user performs a recording reservation operation based on the broadcast preview through a remote controller or the like during the broadcast of the broadcast preview program.

When the video analysis unit 51 receives a request for analysis processing from the control circuit 21 , it captures an image based on the video data from the decoder 12 and holds it in the buffer circuit. The video analysis unit 51 analyzes the content of the video in the broadcast program through known image analysis processing on the captured image and text information included in the video data. The video analysis unit 51 collects video recording reservation-related information necessary for the video recording reservation of the broadcast scheduled program from the captured video in the broadcast preview program, and supplies the collected video recording reservation-related information to the recording unit 26, and associates the information with the current time information. record together.

In addition, as the information related to the recording reservation, the broadcast channel of the scheduled broadcast program, the information on the broadcast start date and time, and the broadcast end date and time are used in the same manner as in the first embodiment.

In addition, the video analysis unit 51 may entrust the collection of the recording reservation-related information to a computer (not shown) on the cloud 60 . In this case, the video analysis unit 51 transmits the video data and captured images supplied from the decoder 12 to the cloud 60 via an interface circuit (not shown) that communicates with the cloud 60 . The computer on the cloud 60 analyzes the image and video data, collects video recording reservation related information, and sends the collected video recording reservation related information to the video analysis unit 51 . The video analysis unit 51 supplies the recording reservation-related information provided from the cloud 60 to the recording unit 26 and records it.

In the present embodiment, the control circuit 21 executes the same recording reservation processing as in the first embodiment every time the recording unit 26 records the recording reservation related information.

Next, the operation of the thus-configured embodiment will be described with reference to FIG. 4 . FIG. 4 is a flowchart for explaining the operation of the second embodiment. In FIG. 4, the same code|symbol is attached|subjected to the same step as FIG. 2, and description is abbreviate|omitted.

The control circuit 21 confirms the interruption from the user (S10). That is, the control circuit 21 confirms whether or not the recording reservation operation based on the broadcast notice by the user occurs or not based on the operation information from the remote controller receiving unit 41, the audio receiving unit 42, and the like. The control circuit 21 repeats step S10 until an interrupt occurs.

Now, it is assumed that the user wishes to make a recording reservation of a scheduled broadcast program introduced by a broadcast preview program currently being broadcast. In this case, the user performs a recording reservation operation based on the broadcast preview during the broadcast of the broadcast preview program. When this interruption occurs, the control circuit 21 entrusts the video analysis unit 51 with the collection of the recording reservation-related information.

In step S11 , the video analysis unit 51 captures an image based on the video data from the decoder 12 , analyzes the content of the scheduled broadcast program, and acquires information about the recording reservation based on the analysis result. In addition, the video analysis unit 51 may transmit video data and captured images to the cloud 60, and may request the collection of information related to the recording reservation. The video analysis unit 51 records the acquired information about the recording reservation in the recording unit 26 .

Next, the control circuit 21 reads the recording reservation-related information recorded in the recording unit 26, and acquires information such as broadcast start date and time (S12). Subsequent operations are the same as those of the first embodiment. That is, the control circuit 21 generates recording reservation information based on the recording reservation-related information in step S5, or sets and holds the recording reservation-related information in step S6. When the program information of the scheduled broadcast program is included in the program table information, the control circuit 21 generates recording reservation information based on the recording reservation-related information in which the recording reservation information is set in step S8.

In this way, also in the present embodiment, the same effects as those of the first embodiment can be obtained.

Also, in the first embodiment, similarly to the present embodiment, it is possible to acquire the information related to the recording reservation by voice analysis using the cloud.

Variation 1

In the above description, an example in which the video analysis unit 51 collects the information related to the recording reservation when the interruption caused by the user's recording reservation operation based on the broadcast notice has been described, but the same method as the first embodiment is also possible. In the same manner, the video analysis unit 51 always performs analysis for acquiring the recording reservation-related information or requests to the cloud 60 .

For example, the video analysis unit 51 may determine, based on the analysis result, whether the program currently being broadcast is a broadcast preview program that previews the broadcast of a scheduled broadcast program, and when it is determined that the program currently being broadcast is a broadcast preview program The video in the broadcast preview program collects the recording reservation-related information necessary for the recording reservation of the broadcast scheduled program, and supplies the collected recording reservation-related information to the recording unit 26, and records it together with the current time information.

In addition, the video analysis unit 51 does not need to judge whether the program currently being broadcast is a broadcast preview program, and if it detects that "0,000,000 o'clock broadcast" and "Tonight broadcast" included in the video of the currently broadcast program Words such as "0 o'clock broadcast" are recorded in the recording unit 26 as recording reservation related information.

In this case, the user may perform a recording reservation operation based on the broadcast preview after viewing the broadcast preview program. The control circuit 21 executes the same recording reservation processing as in the first embodiment every time an interruption occurs due to a recording reservation operation based on a broadcast notice performed by the user.

Variation 2

In the above-described first embodiment, the user needs to perform a recording reservation operation based on the broadcast preview during the broadcast of the broadcast preview program. On the other hand, in Modification 1, the recording reservation process can be performed when the user performs the recording reservation operation based on the broadcast preview after the end of the broadcast preview program, but since the video analysis unit 51 or the cloud 60 is always performed Analysis processing on the computer, so the processing load is large. Therefore, in the second modification, the video data of the broadcast preview program is recorded in the buffer circuit. In this case, the user may perform a recording reservation operation based on the broadcast preview within a predetermined period after viewing the broadcast preview program. In addition, in the second modification, the buffer circuit included in the video analysis unit 51 is configured to have a capacity to hold the video data supplied from the decoder 12 for a predetermined period corresponding to the broadcast time of the broadcast preview program.

When interruption occurs due to the recording reservation operation based on the broadcast notice by the user, the control circuit 21 requests the video analysis unit 51 to perform analysis processing. The buffer circuit sequentially stores video data corresponding to the video from the previous predetermined period to the current time. When an analysis process is requested from the cache circuit 21 , the video analysis unit 51 performs analysis process and an analysis request to the cloud 60 using the video data held in the cache circuit. The video analysis unit 51 supplies the recording reservation-related information acquired in this way to the recording unit 26 and records it.

In this case, the control circuit 21 executes the same recording reservation processing as in the first embodiment every time the recording unit 26 records the recording reservation related information. Accordingly, in this modification, the processing load can be reduced, and recording reservation processing can be performed even when the user performs a recording reservation operation based on the broadcast preview after the broadcast preview program ends.
