DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a karaoke reproducing apparatus according to the present invention will be described below in detail in the order of <karaoke disc> and <karaoke reproducing apparatus> with reference to FIGS. The decoder constituting the karaoke reproducing apparatus 10 in the present invention is a data decompressing unit 14 described later, the detecting unit is a trouble table memory 128 as the first storage unit, the detecting unit is a control unit 125, the display unit is a display unit 129, and the second unit. Is a trouble history memory 127. <Karaoke Disc> FIG. 5 is a diagram showing recording information in the karaoke disc.

The karaoke disc is a well-known CD-ROM
It has an appearance and reproduction characteristics that satisfy the disk standard, and as described below, it uses a series of compressed data signals obtained by compressing digital video signals and digital audio signals according to the MPEG standard, Karaoke software) is sequentially recorded for each song in sector units.

That is, in order to achieve compatibility with a CD-ROM disc, a data transfer rate (readout rate) of 1.5
In order to satisfy Mb / s, the read rate of the data-compressed digital video signal is set to 1.15 Mb / s and the read rate of the data-compressed digital audio signal is set to 0.224 Mb / s. The signals are output in a time division multiplex manner and the read rate is set to 1.3.
By setting the reading rate to 9 Mb / s, the reading rate was kept within the range of 1.5 Mb / s.

The reason is that the upper limit frequency of the video signal is 4.2 MHz, and the read rate of the digital video signal which is not A / D converted and data compressed is 100 Mb.
/ S is required, the upper limit frequency of the audio signal is set to 20 kHz, and the reading rate of the digital audio signal which is not A / D converted and data compressed is 1.4M.
Since b / s is required, the read rate of the signal obtained by time-division multiplexing both of these signals is 101.4 Mb / s, which greatly exceeds the above-mentioned read rate of 1.5 Mb / s. This is because the disk standard cannot be satisfied.

Therefore, by data compression, the data compression rate of the digital video signal becomes 1/87 and the data compression rate of the digital audio signal becomes 1 / 6.3.

The above-mentioned karaoke disc, which is formed by a disc manufacturing technique corresponding to a well-known CD-ROM disc, mainly contains a plurality of karaoke software, and the software numbers corresponding to the arrangement order of the songs are designated. Random access playback is possible only by performing.

Now, a series of data signals recorded on the karaoke disc 1 will be described.

A series of data signals, as shown in FIG.
A known TOC area 2a, which is a lead-in portion of the information track 2, a menu area 2b, and a data area 2c are sequentially recorded. Here, only the vicinity of the reproduction start head of the information track 2 is shown.

In the TOC area 2a described above, a lead-in signal for confirming that reproduction is started by using a reproduction optical pickup (not shown) is recorded.

In the menu area 2b described above, intro information and menu information for each of a plurality of software programs recorded on the disc 1 are recorded, and these are recorded in JIS code as character / symbol code signals.

The menu information is composed of a disc number of the disc 1, a software number for each song, a title character of each software, a singer name, lyrics, and other bibliographic items. Then, the menu information reproduced by the karaoke reproducing apparatus 10 described later is transferred to the printer 5 via the personal computer 30.
No. 0 is printed on the recording paper 51 and used as a quick reference table 70 of the music (illustrated in FIGS. 1 and 4B, respectively). It should be noted that this menu information is recorded in the form of a digital video signal without being encoded as a character / symbol code signal in this way, and this digital video signal is directly printed out by the printer 50 without passing through the personal computer 30. Is also possible.

However, in this case, the menu information cannot be edited and arranged for each disk number and each software number.
The digital video signals are printed out in the order of reproduction.
Further, the disc number and the software number of the menu information are coded so that they can be read by scanning the quick reference table 70 with a bar code reader 71 described later (illustrated in FIG. 4A).

Now, the intro information recorded together with the above menu information is in the form of a digital audio signal in which the melody of the singing part of the song or a part of the lyrics of the singing part is edited for each of a plurality of songs. In order to select this intro information, the disc number and the software number are individually encoded and superposed and recorded in the intro information corresponding to each software.

Note that only the menu information or intro information may be recorded in the menu area 2b. Further, the menu information and the intro information may be recorded on either the outer peripheral portion or the inner peripheral portion of the disc, but it is needless to say that the menu information and the intro information are recorded in a location that does not interfere with normal karaoke performance.

By the way, the above-mentioned data area 2c is composed of a plurality of sectors 2c1 to 2cn and a track 2c11, and the data-compressed digital video signal per song is sequentially recorded in the sectors 2c1 to 2c4, 2c6 and 2c7. The data-compressed 2-channel stereo digital audio signal corresponding to each of the digital video signals recorded in the sectors 2c1 to 2c4 is the sector 2
It is recorded in c5.

Further, in the sector 2cn, character / symbol code signals for various controls relating to the tune concerned are recorded. Furthermore, a truck 2 provided as needed
In c11, sound field data relating to the tune is recorded, which is output from an audio channel different from the audio signal recorded in the sector 2c5 at the time of reproduction and emitted from sound field speakers 64 and 64 described later. <Karaoke Reproducing Device> FIG. 1 is a system configuration diagram of the karaoke reproducing device according to the present invention, FIG. 2 is a block configuration diagram of an embodiment of the karaoke reproducing device according to the present invention, and FIG. 3 is a block diagram of the karaoke reproducing device according to the present invention.

The system configuration of the karaoke reproducing apparatus is shown in FIG.
As shown in, the karaoke reproducing apparatus 10, the personal computer 30, the printer 50, the large color video monitor 60, the color video monitor 61 with a stand, the microphone 6
2, consisting of speakers 63, 63.

The karaoke reproducing apparatus 10 described above selects one of the karaoke disks 1 (for example, 360 pieces) housed therein, according to the user's selection of a music piece, and then reproduces it.

As shown in FIG. 6, the above-mentioned karaoke reproducing apparatus 10 is roughly composed of a housing 10a, racks 10b and 10c, a disk carrier 10e, players 12 and 13, and a disk carrier drive mechanism section 10f.

The racks 10b and 10c described above are cases 10
A large number of sets of discs 1 placed in a tray 3 for racks, which are arranged to face each other in a, are accommodated. The above-mentioned disk carrier 10e moves up and down (arrows B1, B2) between the left rack 10b and the right rack 10c, pulls out the tray 3 on which the desired disk 1 is placed from the rack 10b or the rack 10c, and Only the disk 1 is held by the suction mechanism 10d, the tray 3 is returned to the original storage position of the rack, and then the disk 1 is transported. The above-mentioned players 12 and 13 are racks 10 on the left and right.
The disk carrier 10e is disposed below the b and 10c.
The disk 1 carried by the disk carrier 10e
It is placed on the tray 5 for playing and played (reproduced). The above-described disk carrier drive mechanism section 10f is arranged in the upper left portion of the housing 10a, and moves the disk carrier 10e up and down (arrow B).
Move to 1, B2). 10g is a tray lock mechanism part. The players 12 and 13 described above are arranged symmetrically at the bottom of the housing 10a.

The specific disk 1 placed on the players 12, 13 is mounted on the rack 10 by the disk carrier 10e.
Since it is placed on a predetermined tray 3 housed in b, 10c, the number of the disk rack (disk number),
Since it has two attributes of the song number recorded therein, a specific song can be selected from a large number of discs by specifying the disc number and the song number.

As shown in FIG. 7, the player 12 (13) described above has a well-known structure including a motor 123 having a turntable 122 fixed to its rotation shaft and an optical pickup 124 for reproducing the disc 1. belongs to.
Above the turntable 122, the tray 5 has an arrow M1,
It is provided so that it can be pulled out in the M2 direction, and tray 5
When the disc 1 is placed on the tray 5, the tray 5 is lowered toward the turntable 122 (in the direction of arrow N1) by an elevating means (not shown), and the disc 1 placed on the tray 5 is placed on the turntable 122. Placed. After that, the motor 123 is started, the turntable 122 is rotated at a constant linear velocity, and the optical pickup 124 reproduces the disc 1.

In this case, the read laser beam 153 emitted from the optical pickup 124 needs to be accurately focused on a desired portion of the signal recording surface of the disc 1. The focus mechanism of the optical pickup 124 for this purpose, as shown in FIG. 8, supplies an optimum focus current to the coil 154 in the magnetic field formed by the yoke 150 and the magnet 151 (applies a focus voltage. FIG. 9A). ), The objective lens 152 can be moved up and down (in the directions of arrows N2 and N1. The objective lens shown in FIG. 9B can be moved) to always obtain a focus on the signal recording surface of the disc 1. (The focus detection signal shown in FIG. 9C is at a normal level).

Here, as an example of a defective state, it is normal at the time of shipping, but due to a user's mishandling or the like, a large scratch is generated on the surface of the board or strong dirt is attached to the board. The detection and storage of the trouble code (a trouble code in a poor reproduction state), the disc number, and the song number of the disc 1 in which the portion of the specific song that cannot be focused due to the scattering of the reading laser beam 153 cannot be reproduced will be described. .. The optical pickup 124 described above is supposed to normally perform the focusing operation.

Abnormal reproduction of the disk is detected by the optical pickup 12
4 can be indirectly detected by detecting an abnormality in the focus operation, and the determination is made according to the focus abnormality operation detection flowchart shown in FIG.

That is, when the focus abnormality detection flow of the optical pickup 124 is started (“start focus count = 0” 124a), the focus voltage applied to the coil 154 of the optical pickup 124 is gradually increased from the reference level to the limit 1 level. Raise (“focus voltage rise” 124b), and in FIG.
52 is gradually raised in the upward direction (arrow N2). When the reading laser beam 153 is focused on the disk surface of the disk 1 ("focusing" 124c) during this boosting, the focus abnormality detection flow is detected as normal (focusing) ("end" 124k).

Further, when the reading laser beam 153 is not focused on the surface of the disk 1 during the boosting and the focus voltage reaches the limit 1 level (“focus voltage limit 1” 124d), the limit is reversed. Limit 2 below the reference level for focus voltage at 1 level
The focus lens is gradually lowered to the level ("focus voltage drop" 124e), and the objective lens 152 is gradually lowered in the downward direction (arrow N1) in FIG. If the focus voltage is in focus during this step-down until the focus voltage reaches the limit 2 level (“focus” 124f), the focus abnormality detection flow is detected as normal (focus) (“end” 124k).

If the focus voltage does not reach the limit 2 level during this step-down and the focus voltage reaches the limit 2 level ("focus voltage limit 2" 124g), the focus abnormality detection flow is performed. After counting up the value of a counter (not shown) for counting
h), the series of flows described above (“focus voltage increase” 124 b to “focus voltage limit 2” 124
Repeat g).

Even if this series of flow is repeated three times ("focus count = 3" 124i), if the focus is not achieved, the trouble code, rack number (disk number), and song number corresponding to the abnormal reproduction state of this disc Are stored in the trouble history memory described later ("Trouble code, rack, song number storage" 124j), and this flow is ended ("End" 124l).

In this way, the abnormal reproduction of the disk can be indirectly detected by detecting the abnormal focus operation of the optical pickup 124, and the trouble history thereof is stored in the trouble history memory 127 described later.

As shown in FIG. 11, the conceptual block configuration for performing the flow for detecting the abnormal focus operation shown in FIG. 10 is, as shown in FIG. 11, a controller 125 which is a controller 15, an optical pick-up 124, and player controllers 12a and 1a.
The focus detection unit 126, the trouble history memory 127, the trouble table memory 128, and the display unit 129, which are components of 3a, are included.

The control unit 125 sends a control signal to the effect that the above-described flow for detecting the abnormal focus operation is performed to the optical pick-up 1.
Output to 24. When the focus detection unit 126 detects the focus as described above, the focus detection unit 126 outputs a focus detection signal (normal level shown in FIG. 9C) to the control unit 12.
Output to 5. After detecting the focus, the control unit 125 outputs a control signal for displaying the focus to the display unit 129. In this way, the display unit 129 displays the focus (for example, the focus lamp is changed from the extinguished state to the lit state).

Further, when the focus detection unit 126 detects that the focus is not achieved even if the above-described series of flows is performed three times, the focus detection unit 126 outputs the focus detection signal (FIG. 9C). (Abnormal level shown in FIG. 2) is output to the control unit 125.
After detecting that the object is out of focus, the control unit 125 outputs a control signal indicating that the object is not in focus to the display unit 129. In this way, the display unit 129 does not perform the focus display (for example, the focus lamp is kept off).

At the same time, the control unit 125 stores any of the trouble codes stored in the trouble table memory 128 as trouble codes corresponding to the kinds of troubles that can be detected by performing the above-described focus abnormal operation detection flow. It is determined whether or not it matches with the one, and the corresponding trouble code obtained as a result is given to the control unit 12
5 outputs to the trouble history memory 127 trouble history data obtained by adding the rack number (disc number) code and the song number code of the disc identified in advance, and the trouble history data is stored here. It

Thus, the trouble history data stored in the trouble history memory 127 is as shown in FIG.
Addresses are added and stored sequentially. For example, the trouble history data of address 1270 "180 12 5
“2”, “180” is the rack number, “12” is the song number,
“52” is a trouble code, and indicates a music reproduction failure that occurs when the reproduction is performed by the optical pickup of the player 12. Similarly, "240" of the trouble history data "240 05 52" at the address 1280 is the rack number,
"05" is the song number, "52" is the trouble code,
This shows a music reproduction failure that occurred when the music was reproduced by the optical pickup of the player 12, and also "180" of the trouble history data "180 12 62" of the address 1290.
Is a rack number, "12" is a song number, and "62" is a trouble code, which indicates a song playback failure that occurs when the player 13 plays an optical pickup.

The determination of the trouble code performed by the control unit 125 is performed by the trouble code determination flowchart as shown in FIG.

That is, the control unit 125 reads out the trouble code (trouble code regarding detection of abnormal focus operation) from the trouble table memory 128, and first reads out the trouble code 52 regarding detection of abnormal focus operation of the optical pickup of the player 12 ("start"). 12
8a, "Detect only trouble code 52" 128b), and detect whether or not a specific song portion of the disc being played by the player 12 is defective ("same song in the same rack number" 128c). For example, it is judged that a specific song on a specific disc is abnormal ("a specific song on a specific disc is abnormal" 1
28d).

Further, not only the specific song portion of the disk being reproduced but also the entire disk being reproduced ("same rack number" 128e), the specific disk is judged to be abnormal ("specific disk is abnormal" 128f. ). Furthermore, when all the disks reproduced by the optical pickup of the player 12 are defective in reproduction ("trouble code 52" 128g), it is determined that the player 12 is abnormal ("player 12 is abnormal" 128h). Furthermore, when all the disks reproduced by the optical pickup of the player 13 are defective in reproduction ("trouble code 62" 128i), it is determined that the player 13 is abnormal ("player 13 is abnormal" 128).
j). Then, other abnormalities are also detected ("other abnormalities" 128k).

In this way, an abnormal disk can be specified from a large number of storage disks and a defective player can be specified.
It is also possible to specifically display the result on the display unit 129, such as "the disk of the No. 180 rack is out of focus" or "the player on the right is out of focus". In addition to the display on the display unit 129, it is also possible to perform the same display on the monitors 60 and 61 by a generally called "on-screen circuit".

Although the trouble detection, the judgment, the storage and the display have been described only for the focus operation, the mechanical, electrical and artificial operations (for example, the discs are loaded upside down) related to all other reproducing apparatuses. It is needless to say that the present invention can be similarly applied to such troubles.

As described above, a video image of a moving image, two-channel audio, for each of the songs (maximum 18 songs, 74 minutes in time) recorded in the disk 1 in large numbers,
Data (disk number, software number, song title, singer name, etc.) relating to the musical composition is recorded, and when the selected musical composition is reproduced, these various signals are reproduced and output as necessary. The video signals reproduced from the karaoke reproducing apparatus 10 are output to the color video monitors 60 and 61 for reproduction, the 2-channel audio signals are reproduced by the speakers 63 and 63, and the data relating to the music is transmitted to the personal computer 30. After being output and subjected to data processing in accordance with desired editing, the data is printed on the recording paper 51 by the printer 50. The sound field speakers 64, 64 are connected as necessary.

Here, the karaoke reproducing apparatus 10 described above will be described with reference to FIGS.

The karaoke reproducing apparatus 10 is composed of a changer mechanism section 11, player sections 12 and 13, a data expansion section 14 and a controller 15. The changer mechanism section 11 includes the changer controller 11a and the communication module 11b, and the player sections 12 and 13 include player controllers 12a and 13a. The data decompression unit 14 includes a communication module 14a and a data separation unit 14
b, a controller 14c, a video signal decompression unit 14d, an audio signal decompression unit 14e, and a control signal decompression unit 14f. The controller 15 includes a remote control receiver 15a. The data decompression unit 14 described above
In the middle, the data expansion characteristics of the video signal expansion unit 14d and the audio signal expansion unit 14e are MPE on the karaoke disc.
It has characteristics complementary to the data compression characteristics when the digital video signal and the digital audio signal are compressed according to the G standard.

Next, the reproducing operation of the karaoke reproducing apparatus 10 will be described.

First, the user operates an operation button (not shown) of the controller 15 or the remote control unit 17 to select a desired music piece (software number).

In response to this, the controller 15 temporarily stores the selected software number and displays the selected software number on a display (not shown). Then, in parallel with this operation, based on the built-in soft number vs. disc number comparison data, the disc number of the disc on which the selected soft number song is recorded is retrieved, and in response to this retrieval result, Based on the built-in disk number-to-disk storage part address number comparison data, it is searched for in which part of the disk storage rack (not shown) the disk having the disk number is stored. Based on the search data obtained in this way, a drive control signal for taking out the disk stored in the storage portion to which the address number is attached is output from the output terminal 15b to the input terminal 11a1 of the changer mechanism section 11. ..

The changer controller 11a of the changer mechanism section 11 drives and controls the disk carrier (not shown) as follows based on the applied drive control signal. That is, the disk carrier is moved from the standby state to the driven state, is first transferred at high speed in the direction of the storage portion in which the disk is stored, is transferred at low speed when approaching the storage portion, and is stopped when reaching the position of the storage portion. It After this,
When the disc stored in the storage portion is taken out and placed on the mounting portion of the disc carrier, the disc carrier changes from the stopped state to the driven state, and the player unit 1
The disk is transferred at high speed in two directions. Thus, the disc is placed on the turntable (not shown) of the player unit 12. After this, the disk carrier goes into a standby state again.

Prior to the above case, the controller 15
Recognizes that the disc is not placed on either of the player units 12 and 13, and in that case, the player unit 1
It goes without saying that the control signal for placing the disk in the order of 2 and 13 is output to the changer controller 11a of the changer mechanism section 11.

After that, when the operation button (not shown) of the controller 15 or the remote control section 17 is operated again to newly select a music piece, the disc in which the selected music piece is recorded is the same as that described above. Can be placed on a turntable (not shown) of the player unit 13.

The above-mentioned player controller 12a of the player unit 12 (or the player controller 13a of the player unit 13) sends a rotation control signal for rotating the turntable on which the disc is placed at a constant linear velocity to a motor (not shown). Output to.

As a result, the motor reaches the constant speed rotation state from the stopped state and the turntable rotates at the constant speed. And
In this state, a reproduction data signal is output by reproducing and scanning the disc with an optical pickup (not shown).

In this way, a series of data signals (character / symbol code signals, video signals, audio signals) having the above-described configuration are reproduced, and the player section 12 (or the player section) is reproduced via the bus line 16a1 (or the bus line 16a2). It is supplied from 13) to the communication module 11b of the changer mechanism unit 11, converted into a predetermined communication format here, and then supplied to the communication module 14a of the data expansion unit 14 via the communication line 16b. By the way,
The communication modules 11b and 14a are well-known RS232C.

By the way, the digital data signal supplied to the data decompression unit 14 is output to the data separation unit 14b via the bus line 16c. Separately from this, the changer mechanism section 11 (changer controller 1
1a and the communication module 11b), a control signal (for example, a reproduction start signal) that is sequentially supplied according to various operations selected by the controller 15 described above passes through the communication module 14a of the data decompression unit 14, Line 16d
Is supplied to the controller 14c via.

The controller 14c controls all the components inside the data decompression unit 14, and the line 16d.
A control signal to the effect that the separation of the digital data signal is started is output to the data separation unit 14b based on the control signal provided via the. In response to this, the data separation unit 14b separates and outputs a series of digital data signals supplied from the bus line 16c as a data-compressed character / symbol code signal, a data-compressed video signal, and a data-compressed audio signal. To do. Here, as a method of separating the data signals, the fact that the signals obtained by time-division-multiplexing the above-mentioned three signals are recorded on the disc 1 as a series of data signals is used, and a specific signal is obtained by the time-division timing. Are to be separated.

Of the signals thus separated, the data-compressed video signal is sent to the video signal expansion unit 14d, and the data-compressed audio signal is sent to the audio signal expansion unit 1.
4e, and the data-compressed character / symbol code signal is supplied to the code signal expansion unit 14f via the bus line 16e. At the same time, the controller 14c sends a decompression start signal for decompressing the data to the line 1
Video signal decompression unit 14 via 6f, 16g, 16h
d, audio signal decompression unit 14e, code signal decompression unit 1
Supply to 4f respectively.

The video signal decompression unit 14d decompresses the data-compressed video signal supplied thereto, and then,
A D / A-converted composite video signal and a Y / C separated video signal are simultaneously output. The Y / C video signal is output from the video output terminal (so-called S terminal) 14d11, and the 3-channel composite video signal is output from the video output terminals 14d12 to 14d14. By selectively connecting the above-mentioned color video monitors 60 and 61 to these video output terminals 14d11 to 14d14, video images of moving images can be reproduced.

The audio signal decompression unit 14e decompresses the data-compressed audio signal supplied thereto and then D / A converts it to output a 2-channel audio signal. This audio signal is for L and R channels
It is output from the audio output terminals 14e11 and 14e12. These audio output terminals 14e11, 14e
By connecting the above-mentioned speakers 63, 63 to 12, it becomes possible to reproduce 2-channel stereo sound.

Further, the code signal decompression unit 14f outputs a character / symbol code signal obtained by decompressing the data-compressed character / symbol code signal supplied thereto. This character / symbol code signal is output from the quick reference table data output terminal 14f.
1. Separately output from the music title display dedicated data output terminal 14f2. By connecting the personal computer 30 to the quick reference table data output terminal 14f1 via the interface 18, the printer 50 can be operated to print out the quick reference chart (shown in FIG. 4) on the recording paper 51. Becomes Further, by connecting a display (not shown) to the song title display data output terminal 14f2, the song title can be displayed.

As described above, when all the data decompression operations in the data decompression unit 14 having the above-described configuration are completed, the controller 14c sends an end signal indicating that the data decompression operation is completed to the communication modules 14a and 11b and the changer controller 11a. It outputs to the above-mentioned controller 15 via.

In this way, the reproduction of the selected karaoke song is completed.

Now, the personal computer 30 and the printer 50 described above will be described.

The personal computer 30 has a storage function and an organizing function (editing function), and comprises a memory section, a key operation section, an organizing section, a display section, and a code converting section.

That is, the menu information in the code signal expanded by the code signal expansion unit 14f is stored in the storage unit in the form of character / symbol code signal. This storage unit holds a capacity capable of storing menu information in a plurality of discs. Here, the key operation unit is operated to arrange a large amount of menu information stored in the storage unit into a predetermined format by the arrangement unit. That is, the predetermined format is a pattern printed on the quick reference table 70 shown in FIG. As the method of organizing in the organizing section, various organizing methods such as organizing the titles of the menu information in order of “aiueo” so that they can be printed out or organizing by singer name are possible.

Further, the disk number of the menu information can be replaced in correspondence with the storage number of the rack (not shown). In addition, the data being organized can be organized while viewing it on the display. The menu information arranged in a predetermined format and coded is converted into regular characters / symbols by the character / symbol conversion unit, and then printed by the printer 50 to create the quick reference table 70. Thereby, for example, the menu information of the karaoke disc in which the latest software is recorded can be immediately printed as the quick reference table 70 after being arranged in a predetermined format, so that the user does not lose time for binding and the user can It will be very convenient.

As described above, if the bar code reader 71 (shown in FIG. 4A) is recorded as the menu information so that it can be used, a desired software can be selected from the quick reference table 70 on which the bar code is printed. The menu can be selected without key-in operation, and the selected menu can be registered in the karaoke reproducing apparatus 10 by operating the remote control as it is, which is very convenient. When the menu information is recorded as a video signal without being coded as described above, the track number of the disc is designated and stored in a frame memory (not shown), and the quick reference table 70 is displayed from the printer 50.
Can also be created. However, in this case, it becomes impossible to organize the menu information.
