6 is a flowchart of a command analysis task executed by the CPU 64 of the D player 6. FIG.
FIG. 19 is a flowchart of a DVD playback task for playing a DVD, which is executed by Step 4 in FIG. 19; FIG.
6 is a flowchart showing processing contents of a reproduction file search executed in step 301 of FIG.

First, when the user of the karaoke apparatus 10 points the transmission window 86 of the transmitter 70 to the commander 20 and presses the numeric keypad 78 corresponding to the music selection number of the song to be sung, the keypad corresponds to the numeric keypad 78 each time the keypad is pressed. The number is the song selection number display 7
1 and 23 and the monitors 12 and 13 are sequentially displayed. Subsequently, when the user presses the music selection button 79 after pressing the numeric keypad 78 of the last number, it is determined that the music selection has been completed (step 100), and a request signal requesting transmission of the music data 130 of the selected music is transmitted by the communication cable. 15 to the server 2 (step 120).

Then, the server 2 searches and reads out the music data 130 corresponding to the music selection number indicated by the request signal from the hard disk drive (hereinafter referred to as HDD) 11 in which a plurality of music data are stored, and reads out the music data. The music data 130 thus received is received by the communication modem 49 via the communication terminal 40 of the commander 20 via the communication cable 15 (step 140). Subsequently, the received music data 130 is output from the communication modem 49 and temporarily stored in the RAM 47 (step 160).
Subsequently, the music data 130 is read from the RAM 47 (step 180), and the reproduction method instruction command 160 included in the read music data 130 is transmitted to the DVD player 6 via the interface 59 (step 200).

Here, the contents of the command analysis task executed by the CPU 64 to analyze the command transmitted from the commander 20 will be described with reference to FIG. CPU6
4, when the power of the DVD player 6 is turned on,
The background video file table 100, the program information file table 110, and the parent genre table 120 are read from the DVDs 61A and 62A, and the read tables are stored in the video management table memory 60 (step 202).

Subsequently, the CPU 64 activates a task B (DVD reproduction task) shown in FIG. 18 (step 20).
4). Subsequently, a command transmitted from the commander 20 is received (step 206), and the type of the received command is a reproduction method instruction command 160, a reproduction start command 140 for instructing start of reproduction of a background image, and a stop of reproduction of the background image. Out of the playback stop command 150 (see FIG. 6C) and the reference video setting command (see FIG. 7)
It is determined which command it is (Step 20)
8). Here, since the received command is the reproduction method instruction command 160, the process proceeds to step 210. In step 210, the received reproduction method instruction command 160
"G020: G02A: G
310: G024: G050: G054: G313: G
31D ”in the reproduction instruction table 90 (see FIG. 9).
(A)).

Next, when the reference image setting command 162 (FIG. 7D) is transmitted to the DVD player 6 by the CPU 45 (step 400 in FIG. 16), the CPU 64
The transmitted reference video setting command 162 is received (step 206 in FIG. 17), and the type of the received command is determined (step 208). Here, since the received command is the reference video setting command 162, the process proceeds to step 216, where the reference video data is registered in the reproduction instruction table 90 (FIG. 9A).

Next, when the reproduction start command 140 (see FIG. 6B) is transmitted to the DVD player 6 by the CPU 45 (step 500 in FIG. 16), the CPU 64
The transmitted reproduction start command 140 is received (FIG. 1).
7, the type of the received command is determined (step 208). Here, since the received command is the reproduction start command 140, step 2
Proceeding to 12, the reproduction start message is sent to task B.

Next, a task B (DVD playback task) executed by the CPU 64 will be described with reference to FIG. First, the CPU 64 deletes the content stored in the buffer memory 65 (step 218), and determines whether a reproduction start message has been received (step 220). Here, since the reproduction start message has been received, the process proceeds to step 300 (step 220: Yes). In step 300, a process of selecting a background video file to be played (playback file selection process) is executed.

Next, a reproduction file selection process executed by the CPU 64 will be described with reference to FIG.
The CPU 64 executes a playback file search for searching whether the file name indicated by the first registered data in the playback instruction table 90 (FIG. 9A) is stored in the background video file table 100. (Step 301). Here, the processing contents of the reproduction file search by the CPU 64 will be described with reference to FIG. First, it is determined whether the first character of the data registered first in the reproduction instruction table is “P” or “G”, and if it is “P”, the process proceeds to step 326, and If there is, go to step 304. Here, as shown in FIG. 9A, since the first character is “G”, the process proceeds to step 304, and “020” indicated by the third digit of the second to fourth characters is stored in the background video file table 100. Search for registered items.

Subsequently, as a result of the search, if the same three digits as "020" are found (step 306: Yes), all the file names having the same three digits "020" are registered in the temporary file list. (Step 308). Here, the temporary file list means a list set in the video management table memory 60 for registering a file name read as a result of the search. Here, as shown in the background video file table 100 of FIG.
96. VOB "and" 0A89.VOB ", the two file names are registered in the temporary file list (step 308).

Then, the CPU 64 determines whether there is a file name registered in the temporary file list (step 340 in FIG. 19). Here, since the two file names are registered in the temporary file list, the process proceeds to step 356 (step 340: Ye
s) One file name is randomly selected from the above two file names, and the selected file name is registered in the video management table memory 60 as a file being reproduced (step 356). On the other hand, in step 304,
If a file name matching "020" could not be searched (step 306: No), a file name matching the second digit of the second and third characters with "02" is searched (step 310). If a file name matching "02" exists (step 312: Yes), the file name is registered in the temporary file list (step 3).
14).

For example, the background video file table 10
Assuming that a file name whose three digits match “020” is not registered in “0”, “022” matching “02” is not registered.
H "to" 02AH ", and" 1236.VOB "to" 6789.
A total of nine file names up to "VOB" are registered in the temporary file list (step 314). Then, one file name is randomly selected from those file names, and the selected file name is registered as a file being reproduced (step 356). That is, "0
The file name of the background image specified by “2” (enka / port / ship) is registered as the file being reproduced.

As described above, "General Enka / Port / Ship / Kimono"
The background video specified by DVD 61A and DVD 62
A, even if it is not stored in A, the background image similar to the background image that is not stored is “enka general / minato /
You can select a background image specified by “ship”. If it is determined in step 310 that a file name matching "02" has not been retrieved (step 312: N
o) Search for a file name in which the first digit of the second character is "0" (step 316), and if there is a file name in which the first digit of the second character is "0" (step 318: Ye)
s), and register the file name in the temporary file list (step 320).

For example, the background video file table 10
For 0, if a file name in which the second digit of the second and third characters matches “02” is not registered, “050H” having “0” in the first digit of the second character is changed to “054”.
A total of three file names from "8959.VOB" to "E458.VOB" associated with the genre keyword numerical values up to "H" are registered in the temporary file list (step 320). Then, one file name is randomly selected from those file names, and the selected file name is registered as a file being reproduced (step 356). In other words, "0" (General enka)
The file name of the background video specified by is registered as the file being reproduced.

As described above, even when the background image specified by “enka general / port / ship” is not stored in the DVD 61A and the DVD 62A, the background image “enka” similar to the unstored background image is obtained. The background video specified by "General" can be selected. Step 3
In step 16, if a file name having “0” in the first digit of the second character could not be retrieved (step 318: N
o) One file name is randomly selected from the parent genre corresponding to "0" (step 322) and registered in a temporary file list (step 324).

That is, the genre “A” indicated by “0”
Is a parent genre corresponding to “B” (FIG. 11).
(Refer to (B)), one file name is randomly selected from the file names belonging to the parent genre "B" and registered in the temporary file list (step 324), and the registered file name is used as the file being reproduced. It is registered (step 356). As described above, even when the background video specified by “Enka general” is not stored in the DVD 61A and the DVD 62A, the background specified by the background video “Enka winter” similar to the background video not stored is stored. You can select a video.

Here, in step 324, “5
896. It is assumed that two file names “VOB” and “0A89.VOB” have been registered in the temporary file list. Then, the CPU 64 returns to the reproduction file selection processing shown in FIG. 19, and determines whether or not the file name is registered in the temporary file list (Step 34).
0). Here, “5896.
Since two file names “VOB” and “0A89.VOB” are registered in the temporary file list,
Proceeding to step 356 (step 340: Yes), one of the two file names registered in the temporary file list is selected. Here, “589
6. It is assumed that the file name “VOB” has been selected.

Then, the CPU 64 sets the file name "58
96. Background data corresponding to “VOB”
A or DVD 62A, and transfers the read background video data to buffer memory 65 (FIG. 18).
Step 380). Subsequently, after the transferred background video data is temporarily stored in the buffer memory 65,
The video signal is output to the MPEG decoder circuit 66 and is converted into a background video signal by the MPEG decoder circuit 66. The reason for temporarily storing the read background video data in the buffer memory 65 is that the speed at which the DVD drive reads the background video data is faster than the speed at which the MPEG decoder circuit 66 converts the background video data into a video signal. Since the data conversion of the decoder circuit 66 cannot follow the reading of the background video data, the read background video data is temporarily stored until a predetermined amount of the background video data is converted into the background video signal.

The background video signal output from the MPEG decoder circuit 66 passes through the video output terminal 67 via the video input terminal 58 of the commander 20 to the video control circuit 54.
Is input to The input video signal is converted by the video control circuit 54 into a video signal to be displayed on the monitors 12 and 14 and output to the monitors 12 and 14 via the video output terminals 42 and 43, as shown in FIG. Thus, the background image 300 is displayed. Here, the genre keyword value 101 associated with the randomly selected file name is “020”, so that the background image specified by “General Enka / Port / Ship / Kimono” is displayed on the monitors 12 and 14.
Will be displayed. Also, the file name "5896.VOB"
Is 30 seconds (see FIG. 10), the background video is
14 is displayed for 30 seconds.

Then, the file name is "5896.VO.
B "(step 3)
82: Yes), the process proceeds to step 384, and it is determined whether the reading of the last background video data has been completed. here,
Since the reading of the first background video data has only been completed, and the reading of the remaining seven background video data has not been completed yet, a negative determination is made in step 384, and a negative determination is made in step 30.
Return to 0. Then, the reproduction instruction table 90 shown in FIG.
Of the reproduction instruction data “G02A” registered secondly
The above steps 301 to 326 are executed for.

Here, the second reproduction instruction data is:
Since it is “G02A”, the background video file table 1
00 to “F565.VOB” and “6789.VOB”
The two file names "B" are registered in the temporary file list (step 308), and one of them is selected (step 356) and reproduced (steps 380 and 382). In this case, since the genre keyword numerical value 101 is “02A”, the background image specified by “enka general / port / ship / building” is displayed on the monitors 12 and 14.
Will be displayed.

When the reading of the second background video data is completed (Step 382: Yes), the process returns to Step 300 (Step 384: No) and is registered in the reproduction instruction table 90 of FIG. 9A. Steps 301 to 326 are executed for the third reproduction instruction data “G310”, and the background video data of the file name selected in step 356 is reproduced (step 380,
382). In this case, since the file name associated with “310” is “7C56.VOB”, this “7C56.VOB”
56. The background video data corresponding to "VOB" is read and reproduced. That is, "31" is displayed on the monitors 12 and 14.
A background image of “middle tempo pop / busy / foreign” indicated by “0” is displayed.

Thereafter, the reproduction instruction table 90 shown in FIG.
Steps 301 to 326 are repeated with respect to the third to eighth reproduction instruction data registered in step S 356, and the background video corresponding to the file name selected in step 356 is sequentially reproduced (steps 380 and 38).
2). In this case, since the eighth background video data read is the last background video data, step 218 is performed.
Return to (Step 384: Yes), buffer memory 6
5 and waits for the reception of the command transmitted from the commander 20.

When a new background video is produced, the background video data indicating the new background video is a DV video.
If it is not stored in the D61A and the DVD 62A, the specified new background video cannot be reproduced even if the reproduction method instruction command 160 for specifying the reproduction of the new background video is received. Also, the background video may not be reproduced because the DVD is damaged. Therefore, the DVD player 6 of the present embodiment is characterized in that in such a case, the background video that can be reproduced in place of the unreproducible background video can be reproduced.
U64 executes the processing described below. If the background video cannot be reproduced for the above reason, the file name is not registered in the temporary file list, so the process proceeds to step 342 (step 340: No), and if the background video that is not stored is stored, The reproduction file search of steps 302 to 324 is executed for the reproduction instruction data for instructing the reproduction of the background video reproduced immediately before the order to be reproduced (step 342).

For example, out of the eight pieces of reproduction instruction data registered in the reproduction instruction table 90 of FIG. Is not stored in the temporary playback file list, the steps 302 to 324 are executed for the second immediately preceding reproduction instruction data "G02A", and the file name searched as a result is registered in the temporary file list. (Step 342). If the file name is registered in the temporary file list (step 344: Ye
s), one file name is randomly selected from the registered file names (step 356), and the background video data of the selected file name is reproduced (steps 380 and 382). For example, when the file name “F565.VOB” corresponding to “G02A” is selected,
Instead of the third background image that is not stored, "G
02A "(enka / general / port / ship / building) is reproduced.

If the file name cannot be retrieved by the retrieval in step 342 (step 34
4: No) Steps 302 to 3 for the fourth reproduction instruction data “G024” immediately after the third.
24, and the file name searched as a result is registered in the temporary file list (step 346). If the file name is registered in the temporary file list (step 348: Yes), one file name is randomly selected from the registered file names (step 356), and the selected file name The background video data is reproduced (steps 380, 38)
2). For example, when the file name “E789.VOB” corresponding to “G024” is selected, “G024” is used instead of the third background video that is not stored.
The background video specified by (Enka General / Port / Ship / Gender) is played.

Further, when the file name cannot be searched by the search in step 346 (step 3
48: No), execute steps 302 to 324 for the reference video setting data “G020” registered in the reproduction instruction table 90 of FIG. 9A, and store the file name searched as a result in the temporary file list. Register (step 350). If a file name is registered in the temporary file list (step 352: Yes), one file name is randomly selected from the registered file names (step 35).
6) Play back the background video data of the selected file name (steps 380, 382). For example, "G02
If the file name “0A89.VOB” corresponding to “0” is selected, it is specified by “G020” (enka general / port / ship / ship / kimono) instead of the third background video that is not stored. The background video is played.

If the file name cannot be retrieved by the retrieval in step 350 (step 35
2: No), an error is displayed on a liquid crystal display (not shown) provided on the front panel of the DVD player 6, and the operation of the DVD player 6 is stopped (step 354). In this case, without stopping the operation of the DVD player 6, a message such as "The specified background video is not stored, so please wait until the next background video is displayed." It is also possible to adopt a configuration in which the image is displayed and waits until a background image next to the unstored background image is displayed. In addition, while waiting, the video input of the monitors 12 and 14 may be switched to service information such as new music information prepared by the server 2.

By the way, the process up to the reproduction of the last background image based on the reproduction instruction data registered in the reproduction instruction table 90 has been described above. However, the first background image is actually reproduced. At this time, the tune is played and the lyrics telop is displayed on the monitors 12 and 14. Hereinafter, the reproduction of the lyrics telop data 132 and the performance data 133 (FIG. 6A) constituting the music data 130 will be described with reference to FIG.
This will be described with reference to FIG. MIDI data constituting the performance data 133 included in the music data 130 read from the RAM 47 of the commander 20 is taken into the sequencer 51, and the MIDI sound source 5 according to the count of the timer 53.
2 is written. The sound source signal output from the MIDI sound source 52 is output to the audio control circuit 50 and converted into a music signal that can be amplified by the amplifier 16, and the converted music signal is output to the amplifier 16. And
The output music signal is amplified to the volume set by the amplifier 16 and then output to the speakers 13 and 13 to be reproduced as a performance sound by the speakers 13 and 13 (step 520).

Further, font data corresponding to the lyrics telop data 132 included in the music data 130 is read from the font ROM 44, and the read font data is developed into bitmap data, and
48. Subsequently, the bitmap data is output to the video control circuit 54, and is converted into a display signal that can be displayed on the monitors 12 and 14 by the video control circuit 54. As shown in FIG.
The lyrics telop 302 is displayed on 14. (Step 5
40)

The audio signals input from the microphones 17 and 18 are mixed with the music signal in the amplifier 16, and the mixed signal is output from the audio output terminal 41 to the amplifier 16. Then, the output mixing signal is amplified to the volume set by the amplifier 16, output to the speakers 13, 13, and reproduced as a mixing sound by the speakers 13, 13. In other words, the user plays the song he or she chooses on the screens of the monitors 12 and 14 in the background image 300
And microphone 1 while watching lyrics telop 302

When the reproduction of the music data 130 is completed (step 560: Yes), the reproduction stop command 150 (FIG. 6C) for instructing to stop the reproduction of the background video is output to the DV.
The data is transmitted to the D player 6 (step 580). DVD
Upon receiving the playback stop command 150 (step 206 in FIG. 17), the player 6 determines that the type of command is a playback stop command (step 208), and sends a playback stop message to task B (step 214). Subsequently, in task B, the CPU 64 determines that a playback stop message has been received, and stops selecting a playback file (step 220: No).

On the other hand, the CPU 45 determines whether or not the reserved song selection number data is stored in the RAM 47 (FIG. 1).
(Step 600 of Step 6), if it is stored (Step 600: Yes), the stored music selection number data is read from the RAM 47 (Step 620), and Steps 100 to 580 are executed to reproduce the reserved music. .

As described above, according to the DVD player 6 of the first embodiment, among the background images for which reproduction is instructed by the reproduction method instruction command 160, there are background images that are not stored in the DVD 61A and the DVD 62A. Even if the background image that is not stored is similar to the background image that is similar to the present invention and is similar to the background image, which is the similar image information of the present invention, it is searched whether it is stored in the DVD 61A or the DVD 62A, and the searched similar background image is reproduced. be able to. In addition, if the similar background video cannot be searched by the search, any of the background videos to be played back before and after the order in which the background video data that is not stored is played back when it is assumed that the background video data is not stored is stored. Alternatively, a similar background image similar to the background image can be reproduced.

Further, before and after the order, if the background video not stored or the similar background video similar to the background video is not stored in the DVD 61A and the DVD 62A, the background video is registered in the reproduction instruction table 90. The reference video indicated by the reference video setting data can be reproduced. In other words, a new background video
A and the DVD 62A do not store, and even when the music data 130 designating the reproduction of the new background video is received, a background video similar to the non-stored background video can be reproduced. Therefore, monitor 1
By not displaying the background video on the screens 2 and 14, it is possible to avoid a situation in which the enjoyment of karaoke is spoiled or the atmosphere of the place where the karaoke is performed is flooded.

In the first embodiment, the music data 1
Although the case where the reproduction method instruction commander 160 is included in 30 has been described, the reproduction method instruction commander 17 shown in FIG.
0 or a reproduction method instruction commander 1 shown in FIG.
Even when the background video playback method is instructed by 80,
The above steps are executed by the CPU 45 and the CPU 64. In the case of the reproduction method instruction commander 170, the background image of the movie “Yama Kayama movie” specified by the reproduction instruction data “P236” is reproduced (see FIG. 15), but if the same background image is not stored. If a similar background image of a movie is reproduced and the similar background image is not stored, the reference image “Sapporo Clock Tower” specified by the reproduction instruction data “PFFE” of the reference image setting commander 172 is output. Is reproduced (Fig. 1
5).

Also, in the case of the reproduction method instruction commander 180, the reproduction instruction data “G020: P236: G31”
When the background video data corresponding to any of the reproduction instruction data in “3: PFFE” is not stored, the background similar to the non-stored background video is stored as in the case of the reproduction method instruction commander 160. If the video is searched and the search is not successful, the background video of “middle tempo pops / busy / man and woman” specified by the reproduction instruction data “G313” of the reference video setting command 182 is reproduced.

Next, a video reproducing apparatus according to a second embodiment of the present invention will be described with reference to FIG. FIG.
In step 300 of the DVD playback task shown in FIG.
It is a flowchart which shows the reproduction file selection process performed by U64. The video playback device according to the second embodiment is configured such that when there is a background video that is not stored among a plurality of background videos specified to be played back, the background video that is not stored is stored. The background video reproduced before and after the sequence to be reproduced can be reproduced in place of the background video not stored.

Except for the processing executed by the CPU 64 shown in FIG. 21, the configuration of the DVD player 6 as a video reproducing apparatus and the configuration of the karaoke apparatus 10 are the same as those of the first embodiment.
Since they are the same as the embodiment, their description is omitted.
It is also assumed that the same playback method instruction command 160 and reference video setting command 162 as in the first embodiment are transmitted from the commander 20 to the DVD player 6, and the eight pieces of playback instruction data indicated in the playback method instruction command 160 "G020: G02A: G310: G024: G05
0: G054: G313: G31D ”, the background video indicated by the third reproduction instruction data“ G310 ”is D.
It is assumed that it is not stored in VD61A and DVD62A.

The CPU 64 executes steps 302 to 3 for the first reproduction instruction data "G020".
24 (step 301), and as a result of the search, if a file name is registered in the temporary file list (step 360: Yes), one file name is randomly determined from the registered file names. Is selected (step 373) and reproduced (step 38).
0, 382). Then, the second reproduction instruction data “G0
Also for "2A", the file name is selected by executing steps 301, 360 and 373, and reproduced (steps 380 and 382).

Here, the background video indicated by the third reproduction instruction data “G310” and the background video similar to the background video are DVD61A and DVD62.
A, the process proceeds to step 361 (step 360: No). If the background video that has not been stored is stored, the background video that is played back immediately before the order in which the background video should be played back is stored. Steps 302 to 32 for the reproduction instruction data for instructing the reproduction
The reproduction file search of No. 4 is executed (step 361).
That is, the reproduction file search is executed for the second reproduction instruction data “G02A” (step 361).
Subsequently, if the predetermined file name cannot be retrieved by the retrieval (step 362: No), the background video that has not been stored is one position after the order in which the background video should be reproduced if it is stored. Step 30 for the reproduction instruction data for instructing the reproduction of the background video to be reproduced
The reproduction file search of 2 to step 324 is executed (step 363). That is, the reproduction file search is executed for the fourth reproduction instruction data “G024” (step 361).

Subsequently, when the predetermined file name cannot be searched by the search (step 364: N
o) The reproduction instruction data for instructing the reproduction of the background video to be reproduced two times before the sequence to be reproduced when the unstored background video is assumed to have been stored, in the steps 302 to 324 described above. A reproduction file search is executed (step 365). That is, the reproduction file search in steps 302 to 324 is executed for the reproduction instruction data “G020” immediately before (first) the third reproduction instruction data “G310”, and the searched file name is stored in the temporary file. The file is registered in a list (step 365), and one file name is randomly selected from the registered (step 373).

For example, if the registered file name is “0A89.VOB”, “G020”
A background image specified by (enka / general / port / ship / kimono) is reproduced (steps 380 and 382). If the file name could not be retrieved in step 365 (step 366: No), the process proceeds to step 367, where the unstored background video is to be reproduced in the two order that should be reproduced if it was stored. The reproduction file search of steps 302 to 324 is executed for the reproduction instruction data for instructing the reproduction of the background video to be reproduced later (step 367).

That is, the third reproduction instruction data “G31
0 ”, the reproduction instruction data“ G050 ”two (fifth) after
For the playback file in steps 302 to 324, and registers the searched file name in a temporary file list (step 36).
7) One file name is randomly selected from the registered ones (step 373). For example, assuming that the registered file name is "8959.VOB", the background video specified by "G050" (enka general / country / kimono) is reproduced (steps 380 and 382).

If the file name cannot be searched in step 367 (step 368: No),
A file name corresponding to the reference video setting data “G020” registered in the reproduction instruction table 90 of FIG. 9A is searched and registered in the temporary file list (step 3).
69). If the file name is registered in the temporary file list (step 371: Ye
s) Then, one file name is randomly selected from the registered file names (step 373) and reproduced (steps 380 and 382). For example, if the registered file name is “0A89.VOB”,
The background image specified by "G020" (enka general / port / ship / kimono) is reproduced (steps 380, 382). If the file name cannot be searched in step 369 (step 371: No), the same error display as in the first embodiment is performed, and the DVD player 6 is stopped (step 372). Further, the same messages as in the first embodiment are displayed on the monitors 12 and 14 without stopping the operation of the DVD player 6.

As described above, according to the DVD player 6 of the second embodiment, among the background images whose reproduction is instructed by the reproduction method instruction command 160, there are background images not stored in the DVD 61A and the DVD 62A. In this case, when the similar background video similar to the unstored background video is not present before or after the order in which the background video that is not stored is to be reproduced when the background video that is not stored is stored. However, it is possible to search for and reproduce the similar background video as to whether it exists two before and two after the order. In the second embodiment, the search is made up to two before and two after the order. However, the first (first) and last (eighth) until the similar background video is found.
It can be configured to search up to.

In step 369, the file name corresponding to the reference image setting data is searched if the similar background image does not exist even if the search is performed up to two before and after the above-described order. It is also possible to select a file name from the parent genre of the background video not stored (step 370) and randomly select one file name from the file names registered in the temporary file list by the selection. (Step 37
1: Yes, step 373). For example, if the file name of the unstored background video is "0A89.VO
B ”, the genre keyword numerical value 10
1 is “024” and the genre is enka general (A) (FIG. 12 (B)). Therefore, the genre is 1 from the file name belonging to the parent genre of enka winter (B) (FIG. 11 (B)). Choose two file names randomly.

Further, in each of the above embodiments, the similar background video similar to the non-stored background video is added in the front-back direction of the order to be reproduced when the non-stored background video is stored. As shown in FIG. 23, a predetermined number of file names are selected from the parent genres of the background video that have not been stored without executing the search in the front-rear direction, as shown in FIG. 23 (step 343). (Steps 344, 356).

In each of the above embodiments, a similar background image similar to an unstored background image is placed in the front-back direction in the order in which the background image should be reproduced when the unstored background image is stored. The search configuration was adopted,
As shown in FIG. 24, when the file name cannot be searched in step 301 (step 340: N
o), selecting a background video to be reproduced immediately before the above sequence (step 341); if the selection is not possible (step 344: No), a background video to be reproduced immediately after the above sequence is selected. (Step 345), it is also possible to adopt a configuration for reproducing.

When a plurality of background pictures are reproduced in a picture reproducing apparatus used in a karaoke apparatus, background pictures similar to each other are successively reproduced. Even if one of the background videos reproduced before and after the order in which the background video is stored is selected, a background video similar to the unstored background video can be selected. Therefore, when the background video specified by the reproduction instruction data is not stored in the DVD 61A and the DVD 62A, a similar background video similar to the unstored background video is not searched, and the background video not stored is searched. If stored, any one of the background images to be reproduced before and after the order in which the images should be reproduced can be selected.

That is, if there is no file name having the same three-digit genre keyword value 101 as the reproduction instruction data in step 306, step 310
The system is configured to proceed to step 341 in FIG. 24 without proceeding thereafter. In each of the above embodiments, a case has been described in which a file name specified by one genre and two keywords is registered in the background video file table 100. However, one genre and three or more keywords, or The present invention can be applied to a case where a file name specified only by a keyword without a genre is registered in the background video file table 100.

In this case, in the reproduction file search processing shown in FIG. 20, processing of the number of digits corresponding to the genre and the number of characters of the keyword is executed. In each of the above embodiments, a DVD player provided in a karaoke apparatus has been described as a video playback apparatus of the present invention. However, a DVD player used other than the karaoke apparatus, a CD-R
The present invention can also be applied to an OM player or the like.
