Abstract

PROBLEM TO BE SOLVED: To realize a video reproducer in which background videos are not disturbed by making background videos stored in an MPEG(moving picture expert group) standard so as not complete reproductions in the mid-way of a GOP(group of pictures). SOLUTION: A reproduction time by background video data stored in a buffer memory is calculated in a step 516 to set the reproduction time in a temporary buffer reproduction time T3. The remaining reproduction time T4 remained with respect to the reproduction time of the background video in being reproduced at present by subtracting an actual reproduction time till a point of present time and moreover a temporary buffer reproduction time T3 from a cumulative reproduction instruction time T2 in which reproduction instruction times instructed with respect to respective background videos are cumulated in a step 518. When it is judged that the remaining time T4 is not larger than zero in a step 520, a file is closed. In short, a timing when the reproducing of the background video data stored in the buffer memory is completed becomes a timing when the reproducing of the background videos is completed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus for reproducing an image, in which karaoke is performed by displaying a lyrics telop indicating lyrics and a background image displayed on the background of the lyrics telop on a monitor television. The present invention relates to a karaoke apparatus suitable for reproducing the background video.

[0002]

2. Description of the Related Art Conventionally, as the above-mentioned karaoke apparatus, for example, a so-called communication karaoke apparatus which receives music data from a server having music data via a communication line and reproduces the received music data is known. I have. This communication karaoke apparatus includes a music data reproducing apparatus for performing music selection, reception and reproduction of music data, an amplifier for performing music performance and microphone mixing, a speaker for reproducing a signal output from the amplifier as a sound, a background image. , A monitor television for displaying lyrics telop and background video, a microphone, and the like.

A moving image player has a plurality of (for example, four) CD-ROMs in which a plurality of background images are stored. The playback time of one background image differs depending on the background image. 30 seconds. Also, each background video is stored in association with a genre of a song, such as enka or pop, and each background video is provided with genre data indicating the genre. For example, a background image in which a woman in Japanese kimono appears in an image of a ship anchored in a port, and a background image in which a man and a woman appear in an image of a ship anchored in a port, respectively, are referred to as "enka general Genre data indicating the genre "." The song data is composed of performance data indicating a performance portion of the song, lyrics telop data indicating the lyrics telop, genre data indicating the genre of the song, and the like, and the performance data is MIDI (Musical Instrument Digital Interface).
e) Consist of data.

[0004] In the karaoke apparatus having the above configuration, the moving picture player randomly selects one background video from a plurality of background videos to which genre data corresponding to the genre data included in the music data is attached by using a random number. To play. The background video played by this video player is
Displayed on the monitor TV. The moving image player repeatedly selects and reproduces the background image until the performance of the music ends. For example, assuming that the playback time of the music to be played is 4 minutes and the playback time of one background video is 30 seconds, the above selection and playback are repeated eight times in the same genre, and a total of eight background videos are sequentially monitored. Displayed on TV.

The music data reproducing apparatus receives music data indicating the selected music from the server, and writes performance data included in the received music data to a MIDI sound source.
The signal generated from the MIDI sound source is reproduced by an amplifier and a speaker. Further, the song data reproducing device converts the lyrics telop data included in the song data into a video signal, and the converted video signal is displayed as a lyrics telop on a monitor television.

However, the conventional moving picture player has a problem that the number of background pictures that can be reproduced is small, so that the same background picture is reproduced while repeatedly singing a song of the same genre, and a person who sings karaoke gets tired. . Further, since the selected background video is reproduced for the time stored in the CD-ROM, the background video cannot be switched in response to a change in music. Therefore, DVD (Digital
It has been considered to store more background images than before using a large capacity storage medium such as a Video Disk). Then, it is considered that the genre is subdivided, and scheduling is performed in which the order and reproduction time of the background video belonging to the genre are designated for each piece of music data.

[0007]

FIG. 2 shows an example of scheduling for reproducing a background video stored on a DVD.
6 is shown. This figure shows a time series of a reproduction schedule when the eight background videos A to H are reproduced by designating the reproduction time (unit: second) from t1 to t8, respectively. As shown in the figure, the reproduction time (hereinafter referred to as the reproduction instruction time) instructed for the background video of the third reproduction C is 1
It is assumed that the reproduction instruction time of the background video of D to be reproduced fourth is 30 seconds (t4).

[0008] By the way, in the DVD, it is specified by the MPEG2 standard that moving images are stored in GOP units. Here, MPEG is Moving Picture Experts Gro
Abbreviation of "up" and refers to an international standard for information compression of moving images and related audio. A GOP is an abbreviation of Group Of Picture, which indicates one unit of video compressed according to the MPEG2 standard, and one GOP includes one basic frame indicating a basic image of a moving image and this basic frame. And a set of data indicating how has changed. For example, one GOP has 18 frames. That is, the video stored on the DVD is
Since it is stored in P units, it is read and reproduced in GOP units. Therefore, if the reproduction is terminated in the middle of the GOP, the GOP cannot be reproduced normally,
The image is distorted.

For example, assuming that the reproduction time of one GOP is 0.6 seconds and the reproduction time of background video C is 15 seconds, the background video C No. 1 to No. Total 2 up to 25
This means that it is composed of five (15 / 0.6 = 25) GOPs. That is, the background video C is read from the DVD at 0.6 second intervals. However, the timing at which 14 seconds of the playback instruction time of the background video C ends is No. 24 G
Since the playback ends in the middle of the OP, if the playback is ended at that timing, the playback of No. There is a problem that the background video indicated by 24 GOPs cannot be normally reproduced, and the background video is disturbed.

When the reproduction of the background image C is completed in 13.8 seconds, as shown in FIG.
When the reproduction of the background video is ended by 14.4 seconds, the timing of starting the reproduction of the background video C is delayed by 0.4 seconds. That is, there is a problem that the timing of switching from the background video C to the background video D is shifted. In particular, when the deviation exists between many background images, there is a problem that the deviation is cumulatively increased as the reproduction time elapses.

Therefore, according to the present invention, when the reproduction is terminated between the read timings set for reading the video information, the actual reproduction time is reduced when reproducing the video information which cannot be normally reproduced. When ending between readout timings, an object of the present invention is to realize a video reproducing apparatus capable of normally reproducing video information by matching the end timing with the above readout timing.

[0012]

In order to achieve the above object, according to the present invention, a plurality of video information which can be read at a read timing set at predetermined time intervals are edited. A video reproducing apparatus that reads and reproduces predetermined edited video information from video information storage means in which a plurality of pieces of edited video information are stored, wherein the plurality of pieces of edited video information are stored in the video information storage means. When a plurality of pieces of predetermined edited video information are read and each of the pieces of video data is played back with a specified playback time, a specified end timing at which the playback time specified for the predetermined piece of edited video information ends, and It is determined whether or not a plurality of pieces of video information constituting the edited video information are read out at the readout timing and the actual end timing at which the reproduction ends when the video information is actually reproduced matches the actual end timing. When the determination result indicates that the designated end timing does not match the actual end timing, the actual end timing is set to a predetermined video information among a plurality of pieces of video information constituting the predetermined edited video information. Technical means that timing control means for matching the set read timing is provided is employed.

According to a second aspect of the present invention, in the video reproducing apparatus according to the first aspect, the timing control means determines that a result of the determination by the determination means does not match the designated end timing with the actual end timing. In the case of the above, a technical means is adopted in which the actual end timing is temporally coincident with the readout timing located after the designated end timing.

According to a third aspect of the present invention, in the video reproducing apparatus according to the first aspect, the timing control means determines that a result of the determination by the determination means does not match the designated end timing with the actual end timing. In the case of the above, a technical means is adopted in which the actual end timing is made to coincide with the readout timing that is temporally located before the designated end timing.

According to a fourth aspect of the present invention, in the video reproducing apparatus according to any one of the first to third aspects, the determination is to read out video information constituting the predetermined edited video information. For each time, it is determined whether or not the time difference between the scheduled playback time scheduled to be played back by the read video information and the designated playback time has reached a predetermined value, and the designated end is determined based on the determination result. A technical means for determining whether or not the timing matches the actual end timing is employed.

According to a fifth aspect of the present invention, in the video reproducing apparatus according to the fourth aspect, the determination is made by accumulating the time difference calculated in the calculation performed on the edited video information reproduced up to the previous time. Then, the accumulated time difference is added to the playback time specified for the edited video information to be determined this time, and the time difference between the added playback time and the specified playback time reaches a predetermined value. It is determined whether the specified end timing matches the actual end timing based on a result of the determination.

According to a sixth aspect of the present invention, in the video reproducing apparatus according to any one of the first to fifth aspects, the video information storage means stores the edited video information
A technical means is employed in which the readout timing is stored based on the EG standard and set in a plurality of video information constituting the edited video information corresponds to the GOP unit of the MPEG standard.

According to a seventh aspect of the present invention, there is provided the video reproducing apparatus according to any one of the first to sixth aspects, wherein a predetermined music is reproduced when the edited video information is reproduced by the video reproducing apparatus. A technical means called a musical sound reproducing device provided with a music information reproducing means for reproducing information is employed.

[0019]

According to the present invention, the timing control means reads out a plurality of pieces of edited video information from among a plurality of pieces of edited video information stored in the video information storage means, and reproduces each of the plurality of pieces of edited video information. When a time is designated for reproduction, a specified end time at which a reproduction time designated for predetermined edited video information ends, and a plurality of pieces of video information constituting the edited video information are read out from the predetermined edited video information. It is determined whether or not the readout at the timing and the actual end timing at which the reproduction in the case of the actual reproduction ends coincide with the actual end timing. Then, when the determination result indicates that the designated end timing does not match the actual end timing, the timing control means sets the actual end timing to a predetermined one of a plurality of pieces of video information constituting the predetermined edited video information. In accordance with the readout timing set in the video information.

That is, if reading of predetermined video information is stopped at a timing other than the read timing set for each of the plurality of video information constituting the edited video information, if the predetermined video information cannot be normally reproduced, When it is determined that the specified end time at which the playback time specified for the predetermined edited video information ends does not match the read timing of any one of the plurality of video information constituting the predetermined edited video information, The actual end timing is made to coincide with the readout timing set for the predetermined video information among a plurality of pieces of video information constituting the predetermined edited video information. Thereby, for example, as described in an embodiment of the invention described later, the specified end time at which the specified reproduction time ends is determined by the predetermined GO that constitutes the background video.
When the playback is performed during the playback of the P, by making the actual end timing coincide with the playback start timing (readout timing) of the predetermined GOP, the GO that is not normally played back is set.
It is possible to eliminate the situation where P occurs and the background image is disturbed.

In particular, according to the second aspect of the present invention, when the result of determination by the determination means indicates that the designated end timing does not match the actual end timing, the actual end timing is temporally designated. The read timing coincides with the read timing located after the end timing. In other words, if the specified end timing does not match the actual end timing, the video information for which the readout timing is set immediately before the specified end timing cannot be normally reproduced, but the actual end timing is temporally shifted from the specified end timing. By making the read timing coincide with the read timing located later, the video information can be normally reproduced. For example, as described in an embodiment of the invention described below, when there is a GOP whose readout timing does not match the designated end timing, the reproduction of the background video is ended at the timing at which the reproduction of the GOP is completed. The situation where the background image is disturbed can be avoided.

On the contrary, in the invention according to claim 3,
When the result of the determination by the determining means is that the designated end timing does not match the actual end timing, the timing control means reads the actual end timing temporally before the designated end timing. Match the timing. That is, if the specified end timing does not match the actual end timing, the video information for which the readout timing is set immediately before the specified end timing cannot be normally reproduced, but the actual end timing is temporally shifted from the specified end timing. By making the read timing coincide with the preceding read timing, the reproduction of the video information can be stopped. Thus, it is possible to avoid a situation in which the video is disturbed when the video information is reproduced. For example, as described in an embodiment of the invention described below,
GO whose read timing does not match the designated end timing
When P exists, the reproduction of the background video is terminated at the timing when the GOP immediately preceding the GOP is read, so that the background video can be prevented from being disturbed.

Further, in the invention described in claim 4, the determination is made such that each time the video information constituting the predetermined edited video information is read, the scheduled playback time scheduled to be played back by the read video information Is calculated before playback, and it is determined whether or not the time difference between the calculated expected playback time and the specified playback time has reached a predetermined value. Based on the determination result, the specified end timing and actual end are determined. It is determined whether or not the timing matches. In other words, when the specified end timing does not match the actual end timing,
Since there is a difference between the playback time specified for the edited video information and the playback time when the edited video information is actually played, the difference is calculated before the read video information is played. Then, by judging whether or not the magnitude of the operation value has reached a predetermined value, it is possible to know a mismatch between the two timings before the designated end timing.

In particular, in the invention according to claim 5, the determination is made by accumulating the time difference calculated in the calculation performed on the edited video information reproduced up to the previous time, and determining the accumulated time difference by the current time. Is added to the playback time specified for the edited video information to be determined, and it is determined whether or not the time difference between the added playback time and the specified playback time has reached a predetermined value. Based on the result, it is determined whether or not the designated end timing matches the actual end timing. In other words, if there is a time difference between the playback time specified for the edited video information and the playback time when the edited video information is actually played, the time difference is set to the playback time specified for the next edited video information to be played. , It is possible to prevent the time difference from being carried over to the reproduction of edited video information to be reproduced later as the time difference. Accordingly, it is possible to prevent the timing of switching from one piece of video information to another piece of video information from being gradually shifted due to the accumulation of the time differences.

Further, the technical means according to any one of claims 1 to 5 is such that the edited video information is stored in the video information storage means as an MP.
It is suitably adopted for a video reproducing device stored based on the EG standard. That is, for example, as described in an embodiment of the invention described later, a DVD that stores background video data indicating a background video in accordance with the MPEG2 standard has a configuration in which each background video is composed of a plurality of GOPs. This is because if the reproduction of the background video data is terminated halfway, the background video indicated by the GOP cannot be normally reproduced, but the background video can be reproduced without disturbing by adopting the above technical means.

Further, according to the video reproducing apparatus of any one of the first to sixth aspects, when the edited video information is reproduced, the predetermined music information is reproduced. It is suitably used for a musical sound reproducing device provided with a music information reproducing means for reproducing the music. That is, for example, as described in an embodiment of the invention described later, in a karaoke apparatus as a musical sound reproducing apparatus, when reproducing music data as music information, a background video is displayed on a monitor screen. By adopting each of the above technical means in a DVD player as a video reproducing apparatus to be reproduced, the background video displayed on the monitor screen during karaoke is disturbed, and the karaoke player gets excited. This is because it can avoid.

FIG. 22 is a flowchart showing the contents of the file search algorithm executed in step S0, and FIG. 22 is a flowchart showing the contents of the file search algorithm executed in step S350 or step S370 of FIG.

First, when the user of the karaoke apparatus 10 points the transmitting window 86 of the transmitter 70 to the commander 20 and presses the numeric keypad 78 corresponding to the song 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).

The server 2 retrieves and reads out the music data 130 corresponding to the music selection number indicated by the request signal from the hard disk drive (HDD) 11 in which a plurality of music data is stored, and reads out the read music data. 130 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 stored in the RAM 47.
(Step 160). Then, RAM
The song data 130 is read out from 47 (step 18).
0), 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, the parent genre table 120, the reproduction instruction table 90, and the like are read from the DVDs 61A and 62A, and the read tables are stored in the video management table memory 60 (step 10). ).

Subsequently, an instruction pointer indicating the position of the search target is set at the head of the background video file table 100 (step 20), and task B (DVD playback task) shown in FIG. 18 is started (step 30). Subsequently, the command transmitted from the commander 20 is received (step 2).
02), the received command types include a reproduction method instruction command 160, a reproduction start command 140 (FIG. 6B) for instructing the start of reproduction of a background video, and a reproduction stop command 150 (FIG. 6B) for instructing a stop of reproduction of the background video. It is determined which one of the commands shown in FIG. 6C and the other commands is present (step 204). Here, since the received command is the reproduction method instruction command 160, the process proceeds to step 206.

In step 206, the reproduction instruction content “G02” indicated by the received reproduction method instruction command 160
0, 30: G02A, 30: G054, 14: G02
4, 30: G050, 25: G029, 25: G02
2, 20: G023, 30 ”in the reproduction instruction table 90 of the video management table memory 60 (FIG. 9A).
reference). Subsequently, "NULL" is set at the position of the number of registered reproduction instruction data + 1 (step 208). Here, since a total of eight pieces of reproduction instruction data are registered as shown in FIG. 9A, “NULL” is set at the ninth (8 + 1 = 9) position. Subsequently, an instruction pointer is set at the head of the reproduction instruction table 90 (step 210),
It waits for the next command (step 202).

When a reproduction start command 140 is transmitted to the DVD player 6 by the CPU 45 (FIG. 16).
The CPU 64 receives the transmitted playback start command 140 (step 216 in FIG. 17) (step 20 in FIG. 17).
2), the type of the received command is determined (step 204). Here, since the received command is the reproduction start command 140, the process proceeds to step 212, and a reproduction start message is sent to the task B.

Next, the task B (DVD playback task) executed by the CPU 64 will be described with reference to FIG. First, the CPU 64 reads the file under reproduction 192 (FIG. 2) for registering the file determined to be reproduced.
3 (B)) is set to "invalid" and the contents stored in the buffer memory 65 are erased (step 218). Subsequently, the type of the message sent from task A is determined (step 220). Here, since the reproduction start message has been received, the process proceeds to step 222, and it is determined whether the file being reproduced is set to “invalid”. Here, since the file being reproduced is set to "invalid" in step 218, the process proceeds to step 224 (step 22).
2: Yes).

At step 224, the reference clock T1 is reset and the reference clock T1 is started. At step 226, 0 is set to the cumulative reproduction instruction time T2. Here, the cumulative reproduction instruction time T2 indicates a time obtained by accumulating the reproduction instruction time t specified in the already reproduced file. Then, the CPU 64 determines that the file being played back 1
A process of selecting a file name to be registered in 92, that is, a reproduction file selection algorithm for selecting a file to be reproduced from the background video file table 100 is executed (step 300).

Next, the reproduction file selection algorithm executed by the CPU 64 will be described with reference to the flowchart of FIG. The CPU 64 deletes the registered data of the temporary file list 190 shown in FIG. 23A to make it empty (step 302). Here, the temporary file list 190 is the file name data 10 selected from the background video file table 100 by executing this playback file selection algorithm.
2 is a list for registering No. 2. And the CPU 64
Reads the reproduction instruction data 92 at the instruction pointer position in the reproduction instruction table 90 (FIG. 9A) (step 30).
4).

Here, since this is the first file selection, the reproduction instruction data “G020” registered first in the reproduction instruction table 90 is read (step 30).
4). Subsequently, the read reproduction instruction data 92 indicates “NUL
L is determined (step 306).
Since it is not “LL”, the process proceeds to step 308, and the first character of the read reproduction instruction data 92 is “P” or “G”.
Is determined. If it is "P", the process proceeds to step 382. If it is "G", the process proceeds to step 310.
Proceed to. Here, the read reproduction instruction data “G02
Since the first character of “0” is “G”, the process proceeds to step 310.

At step 310, the reproduction instruction data 92
A file search algorithm (3-digit comparison) for searching whether a file name having a number and a symbol that match the third digit of the second to fourth characters at the beginning of the genre keyword number 101 is registered in the background video file table 100 ). Here, the third character of the second to fourth characters
Since the digit is "024", it is searched whether a file name having "024" at the beginning of the genre keyword numerical value 101 is registered in the background video file table 100 (step 310).

Here, the file search algorithm (three-digit comparison) executed in step 310 will be described with reference to the flowchart in FIG. Here, it is assumed that the third digit of the second to fourth characters of the reproduction instruction data 92 read from the reproduction instruction table 90 in step 304 is “024”. CPU64
Determines whether the first three digits of the genre keyword value 101 of the file registered first in the background video file table 100 match "024" (step 312), as shown in FIG. The first three digits of the genre keyword value 101 of the file registered first in the background video file table 100 are “005”.
, And does not match “024”, so step 322
(Step 312: No), and move the instruction pointer to the next file, that is, the second registered file.

Subsequently, it is determined whether or not the instruction pointer is beyond the last registered file in the background video file table 100, that is, whether or not all files have been searched (step 320). Since the search of the th file has only been completed, step 312
(Step 320: No) The first three digits of the genre keyword value 101 of the second file are “02”.
4 ". In this manner, until a file in which the first three digits of the genre keyword numerical value 101 match “024” is found, that is, step 312
Steps 312 and 322 until a positive determination is made
And step 320 is repeated.

If a file in which the first three digits of the genre keyword number 101 match "024" is found (step 312: Yes), the set reproduction time data T registered in the file is temporarily set and reproduced. The temporary setting reproduction time data registration file 194 shown in FIG. 23C is registered as the time data TA (step 314). Subsequently, it is compared whether the registered temporary setting reproduction time data TA is equal to or longer than the reproduction instruction time data t registered first in the reproduction instruction table 90 (step 316). That is, it is determined whether the reproducible time of the found file can satisfy the specified replay time.

Here, as shown in FIG. 10, as a file whose first three digits of the genre keyword numerical value 101 match “024”, the file name is “E789.VO”.
Since the file “B” is found first, the set reproduction time data “35” is registered in the temporary set reproduction time data registration file 194 as the temporary set reproduction time data TA (step 314). Since the reproduction instruction time data t registered first in the reproduction instruction table 90 is “30”, TA (35) ≧ t
(30), the process proceeds to step 318 (step 31).
6: Yes), and register the file name “E789.VOB” in the temporary file list 190.

Thereafter, similarly, for the two files with the file names “0A89.VOB” and “FD01.VOB” whose first three digits of the genre keyword numerical value 101 match “024”, the set reproduction time is also set. It is determined whether the data T is equal to or longer than the reproduction instruction time data t (steps 314 and 316). However, as shown in FIG.
8 ", which is smaller than" 30 "of the reproduction instruction time data t, the file names of both files are not registered in the temporary file list 190 (step 316: N
o).

Then, the CPU 64 determines whether or not the number of registered file names registered in the temporary file list 190 is 0 (step 324 in FIG. 19).
, A file name is randomly selected from the file names registered in the file 192 based on a random number, and the selected file name is registered in the file 192 being reproduced (step 3).
86). Here, since the file name registered in the temporary file list 190 is only “E789.VOB”, the file name “E789.VOB” is registered in the playing file 192 (step 386).

Subsequently, the CPU 64 moves the instruction pointer of the reproduction instruction table 90 forward by one, and ends the reproduction file selection algorithm. Here, the instruction pointer is set to the second reproduction instruction data 9 in the reproduction instruction table 90.
Proceed to step 2 to end the playback file selection algorithm. On the other hand, in step 310, the reproduction instruction data 9
If the file having the number and symbol that match the three digits of the second to fourth characters of No. 2 at the beginning of the genre keyword number 101 cannot be searched (step 324: number of registrations = 0), the reproduction instruction data 92 A search is made for a file having a number and symbol that match the two digits of the second and third characters at the beginning of the genre keyword numerical value 101 (step 330). Here, a file having “02” at the head of the genre keyword numerical value 101 is searched.

FIG. 21 shows the contents of the file search algorithm (two-digit comparison) executed in step 330. The processing contents in steps 332 to 342 are the same as those in step 332 except that a file having a number and a symbol at the beginning of the genre keyword value 101 that match the second and third characters of the reproduction instruction data 92 is searched. Step 314 shown in FIG.
Since this is the same as step 322, the description is omitted.
Assuming that no file having “020” at the beginning is registered in the background video file table 100, “0”
As shown in FIG. 10, the genre keyword numerical value 101 having “2” at the top is “022H”, “023”.
H "," 024H "," 029H "and" 02AH]
Are registered, and each genre keyword numerical value 1
01, "1236.V
OB "," E589.VOB "," E789.VO
B "," 0A89.VOB "," FD01.VOB ",
“FF45.VOB”, “8959.VOB”, “F5
65. A total of nine files having file names of “VOB” and “6789.VOB” are registered.

Therefore, each set reproduction time data T registered in each of the nine files is compared with the reproduction instruction time data t (step 336). As a result, “E589.VOB” and “E789.
VOB "," FF45.VOB "," 8959.VO "
B "," F565.VOB "and" 6789.VO "
B) are registered in the temporary file list 190 (step 338), and one file name is selected at random from among them, and
92 (step 386 in FIG. 19). In this way, even if the file specified by “020” (enka / port / port / ship / kimono) is not stored, it is specified by “02” (enka / port / port / ship) similar to that file. File 1 playing back the background video file name data 102
92 can be registered.

If it is determined in step 330 that the file having the number and symbol corresponding to the second and third digits of the reproduction instruction data 92 at the head of the genre keyword numerical value 101 cannot be searched (step 344). : Number of registrations = 0), and search for a file having a numerical value and a symbol that match the first digit of the first character of the reproduction instruction data 92 at the beginning of the genre keyword numerical value 101 (step 350). Here, a file having “0” at the beginning of the genre keyword numerical value 101 is searched. FIG. 22 shows the contents of the file search algorithm (one-digit comparison) executed in step 350. The processing contents from step 352 to step 362 are as follows:
20 is the same as steps 314 to 322 shown in FIG. 20, except that a file having a number and symbol that match the first digit of the first character of the reproduction instruction data 92 at the beginning of the genre keyword numerical value 101 is searched. Description is omitted.

In the background video file table 100,
Assuming that a file having “02” at the beginning is not registered, as the genre keyword numerical value 101 having “0” at the beginning, as shown in FIG.
“050H” and “054H” are registered, and “7895.VOB” and “895” are stored as files associated with the respective genre keyword numerical values 101.
9. VOB "," 7896.VOB "and" E45
8. A total of four file names “VOB” are registered.
Therefore, each set reproduction time data T registered in each of these four files is compared with the reproduction instruction time data t (step 356). As a result, one file name “8959.VOB” having the set reproduction time data equal to or longer than the reproduction instruction time data “30” is registered in the temporary file list 190 (step 35).
8) The file name is selected and the file 19 being reproduced is
2 (step 386 in FIG. 19). As described above, even when the file specified by “02” (enka / port / ship) is not stored, the file name of the background video specified by “0” (enka generally) is similar to the file. The data 102 can be registered in the playing file 192.

Further, if it is determined in step 350 that the file having the number and symbol corresponding to the first digit of the first character of the reproduction instruction data 92 at the head of the genre keyword numerical value 101 cannot be searched (step 364: registration number = 0), search for a file registered in the parent genre of the genre indicated by the first digit of the first character of the reproduction instruction data 92 (step 370). Here, since the parent genre corresponding to the genre “A” indicated by “0” is “B (enka winter)” (see FIGS. 11B and 12B), the parent genre “B ( 1), that is, a file name having “1” at the beginning of the genre keyword numerical value 101 is searched.

This search is executed by the file search algorithm (one-digit comparison) executed in step 350 (step 370). If there is a file name registered in temporary file list 190 (step 372: number of registrations) > 0), one file name is randomly selected from the registered file names and registered in the file 192 being reproduced (step 386). As described above, even when the file specified by “0” (enka general) is not stored, “1” similar to that file is not stored.
File name data 1 of background video specified in (Enka winter)
02 can be registered in the playing file 192.

If the first character of the reproduction instruction data 92 read out in step 304 is "P" (step 308: P), the program indicated by the number and symbol attached to the part after "P" The program information file table 110 (FIG. 11)
(A)), and the searched file name is registered in the temporary file list 190 (step 382). If the file name is registered in the temporary file list 190 (step 384:
Then, one file name is randomly selected from the registered file names and registered in the file 192 being reproduced (step 386).

For example, if the reproduction instruction data 92 is “P23
In the case of “6”, two file names “5666.VOB” and “5667.VOB” are registered in the temporary file list 190 (FIG. 11).
(A)), either one of the two file names is registered in the file 192 being reproduced. If the file name is not registered in the temporary file list 190 as a result of executing the steps 302 to 370 (step 372: number of registrations = 0), an error is displayed and the reproduction is stopped (step 374). . For example, an LED (not shown) for error display provided on the front panel of the DVD player 6 or the commander 20 is turned on, or an error message is displayed on a liquid crystal display. Alternatively, a message image such as "The designated background image is not stored. Please wait as it is." Is displayed on the monitors 12 and 14.

Next, returning to task B shown in FIG. 18, steps 500 and thereafter, which are features of the video reproducing apparatus of the present invention, will be described. The CPU 64 opens the file corresponding to the file name registered in the playing file 192 (step 5).
00), the reproduction instruction time t is added to the cumulative reproduction instruction time T2, and the added time is set as the cumulative reproduction instruction time T2 (step 502). Here, the first file is reproduced, and since there is no previously reproduced file, the cumulative reproduction instruction time T2 = 0, so that the reproduction instruction time t is set to the cumulative reproduction instruction time T2 (step 502). ). For example, since the reproduction instruction time t registered first in the reproduction instruction table 90 is “30”, “30” is set as the cumulative reproduction instruction time T2.

Subsequently, one GOP of background video data is read from the DVD 61A or the DVD 62A in which a file corresponding to the file name registered in the file 192 being reproduced is stored (step 510). continue,
Measurement using the reference clock T1 is started (step 51).
2) Transfer the read background video data for one GOP to the buffer memory 65 (step 514). Subsequently, the playback time based on the background video data stored in the buffer memory 65 is calculated, and the calculated playback time is set as a temporary buffer playback time T3 (step 51).
6).

Since background video data is stored in the buffer memory 65 in GOP units, if the playback time for one GOP of background video data is known, the unit playback time is determined by the number of GOPs stored in the buffer memory 65. , The temporary buffer reproduction time T3 can be obtained. For example, assuming that the reproduction time of the background video data for one GOP is 0.6 second and 10 GOPs are stored in the buffer memory 65,
Temporary buffer playback time T3 = 0.6 seconds × 10 =
6.0 seconds.

Subsequently, the actual reproduction time (time actually reproduced until now) T1 is the cumulative reproduction instruction, except for the reproduction time (background reproduction time of the present invention) by the background video data stored in the buffer memory 65. An operation for calculating a time T4 remaining until reaching the time T2 (hereinafter referred to as a remaining reproduction time) is performed (step 518). In order to calculate the remaining reproduction time T4, first, the cumulative reproduction instruction time T2
From the actual playback time T1 measured by the reference clock T1
Is performed. In other words, it calculates how much time remains before reaching the cumulative reproduction instruction time T2 at the present time. Here, since the reproduction of the first file has just started, the reference clock T
Assuming that the measurement time by 1 is 0, T2−T1 = 35 seconds−
0 = 35 seconds.

Then, the calculated time (T2-T
An operation for further subtracting the temporary buffer reproduction time T3 from 1) is performed (step 518). That is, since the background video data to be reproduced next has already been stored in the buffer memory 65, the time (T3) that can be reproduced by the stored background video data is calculated as the calculated time (T2- T1) is subtracted, and a time substantially remaining until reaching the cumulative reproduction instruction time T2 (remaining reproduction time T4) is calculated (step 518). For example,
Assuming that the temporary buffer playback time T3 = 6.0 seconds,
The remaining reproduction time T4 = 35 seconds−6 seconds = 29 seconds.

Next, whether the remaining reproduction time T4 is greater than 0 (positive or negative), that is, the timing at which the specified reproduction time ends (designation end timing of the present invention), and the actual reproduction ends It is determined whether the timing (actual end timing of the present invention) coincides with the timing (step 52).
0). And when the remaining reproduction time T4 is larger than 0,
That is, even if the background video data stored in the buffer memory 65 at this time is reproduced, the actual reproduction time T1
Is insufficient for the cumulative reproduction instruction time T2 (when the designated end timing and the actual end timing do not match)
Advances the read pointer set in the file of DVD 61A or DVD 62A by one GOP (step 522). That is, a preparation is made to read out the background video data for the next 1 GOP.

Subsequently, the process proceeds to step 220. Here, since no message has been sent from task A, the process proceeds to step 504 to determine whether or not the file being reproduced is set to "invalid". Here, since the file being reproduced is not set to “invalid” in step 218, the process proceeds to step 506 (step 504: No), the free size of the buffer memory 65 is detected, and
If there is more than GOP (Step 508: Yes), 1
The background video data for the GOP is read (step 51).
0), and transfer to the buffer memory 65 (step 51).
4).

Subsequently, as described above, the remaining reproduction time T
4 (steps 516 and 518), and if the remaining reproduction time T4 is greater than 0 (step 520: Ye)
s), the next one GOP worth of background video data is read (steps 522 and 510), and steps 514 to 520 are executed. In this way, the background video data is sequentially read from the file in units of 1 GOP, and the remaining reproduction time T4 is calculated at the read timing. And
Until the remaining reproduction time T4 is determined to be 0 or less in Step 520 (Step 520: No), that is, by reproducing the background video data stored in the buffer memory 65, the actual reproduction time T1 becomes the cumulative reproduction instruction time. T
In order to reach 2, the above steps are repeatedly executed until it is determined that it is not necessary to newly read the background video data.

When it is determined that the remaining reproduction time T4 is 0 or less (step 520: No), the file being reproduced is closed (step 524). This allows
The reproduction of the file ends when the reproduction of the background video data stored in the buffer memory 65 ends (the specified end timing and the actual end timing match). Subsequently, a reproduction file selection algorithm is executed for the reproduction instruction data 92 registered second in the reproduction instruction table 90 (step 300), and the second file registered in the file 192 being reproduced by the execution is executed. Step 5 as for the first file
From step 00, step 524 is executed.

Here, a case where the reproduction of the second file is completed and the third file is reproduced will be described with reference to FIG. Note that the third reproduction instruction data “G0
As a result of executing the playback file selection algorithm on “54”, the file name “E45”
8. VOB "is registered. It is also assumed that the reproduction instruction time t of the file having the file name “E458.VOB” is 14 seconds, and the total actual reproduction instruction time T1 of both the first and second reproduced files is 60 seconds. Further, in the reproduction of the first and second files, it is assumed that the reproduction instruction time t and the actual reproduction time T1 match, and that the reproduction instruction time t does not become excessive or insufficient.

Each time one GOP of background video data is read from the file with the file name "E458.VOB", the remaining reproduction time T4 is calculated in the same manner as in the case of the first file (step 518), and the remaining reproduction time T4 is calculated. Is greater than 0 (step 520). Here, No. No. 1 to No. The reproduction of the background video data for nine GOPs up to 9 has been completed. 10 to No. It is assumed that background video data for 15 GOPs up to 24 is stored.

The cumulative reproduction instruction time T2 is the cumulative reproduction instruction time T2 of the synthesis of the first file and the second file.
Is 60 seconds, and the third reproduction instruction time t is 14 seconds. Therefore, a new cumulative reproduction instruction time T2 is T2 + t = 6.
0 seconds + 14 seconds = 74 seconds (step 502). Also, since the playback of nine GOPs has been completed, the actual playback time T1 measured from the start of playback of the first file
Is 60 seconds + 0.6 seconds × 9 = 65.4 seconds. Further, since the background video data for 15 GOPs is stored in the buffer memory 65, the temporary buffer reproduction time T3 is 0.6 seconds × 15 = 9.0 seconds (step 516). Therefore, the remaining reproduction time T4 is equal to T2-
T1-T3 = 74 seconds−65.4 seconds−9.0 seconds = −0.4
Seconds (T4 <0).

Therefore, if all of the background video data stored in the buffer memory 65 is reproduced at the present time, the actual reproduction time T1 becomes 0.4 times the cumulative reproduction instruction time T2.
It is estimated that seconds will be exceeded. That is, by reproducing all the background video data stored in the buffer memory 65, the target cumulative reproduction instruction time T2 can be satisfied. Therefore, since it is not necessary to read the background video data for the next 1 GOP, the file being reproduced “E45
8. VOB "is closed (step 520: No, step 524), the next fourth file to be reproduced is selected (step 300), and reading of the background video data of the selected file is executed (steps 500 to 500). Step 524).

The background video data temporarily stored in the buffer memory 65 is transmitted to the MPEG decoder circuit 66.
(FIG. 4) and is converted to a background video signal by the MPEG decoder circuit 66. Then, the background video signal output from the MPEG decoder circuit 66 is input to the video control circuit 54 via the video input terminal 58 of the commander 20 via the video output terminal 67. The input video signal is supplied to the monitors 12 and 14 by the video control circuit 54.
Is converted to a video signal to be displayed on the video output terminal 4
25, and are output to the monitors 12 and 14 via
, A background image 300 is displayed.

For example, if the file name of the third reproduced file is “E458.VOB”, the genre keyword numerical value 101 associated with the file name “E458.VOB” is “054”. ,
The background image specified by “General Song / Country / Child” is displayed on the monitors 12 and 14 for 14.4 seconds. Thereafter, the fifth to eighth background video images are sequentially displayed on the monitors 12 and 14 by executing the same steps as described above. When the playback stop command 150 is transmitted from the commander 20 to the DVD player 6 (step 660 in FIG. 16), the CPU 64 determines in step 204 that the type of the received command is the playback stop commander 1
50, the process proceeds to step 214, and a reproduction stop message is sent to task B.
8, the file being played is set to "invalid", the contents stored in the buffer memory 65 are erased, and the process waits until a message sent from the task A is received (step 22).
0).

As described above, according to the DVD player 6 of the first embodiment, when the background video data stored in the buffer memory 65 is played back, is the actual playback time T1 longer than the cumulative playback instruction time T2? If it is determined that the video data exceeds the limit, the reading of the next new background video data is prohibited, and the reproduction of the background video is stopped when the reproduction of the background video data stored in the buffer memory 65 is completed. Can be terminated. That is, the end timing (designated end timing) of the actual reproduction time T1 can be temporally matched with the read timing positioned after the designated end timing of the actual reproduction time T1. Therefore, normal reproduction of the background video data cannot be performed by ending the background video between read timings of the background video,
It is possible to eliminate a situation in which the background images displayed on the monitors 12 and 14 are disturbed.

Also, as described above, the actual reproduction time of the third file is 14.4 seconds, which is 14 seconds of the reproduction instruction time.
0.4 seconds over the second, but the excess
Four seconds is measured as the actual reproduction time T1. Then, the actual reproduction time T1 including the excess is calculated in step 5
In 18, the actual reproduction time of the fourth file is reduced by 0.4 seconds because it is subtracted when calculating the remaining reproduction time T4.

That is, the excess of the actual playback time of the third file is subtracted from the actual playback time of the next fourth file. It is not carried over to the calculation of the remaining playback time of the file. Therefore, since the error between the actual reproduction time of the previously reproduced file and the reproduction instruction time does not shift until the subsequent reproduction, the switching timing between the background videos gradually increases as the reproduction of the background video progresses. Nothing.

By the way, the process of reproducing the background video has been described so far. However, actually, the tune is played at the timing when the first background video is reproduced, and the lyrics telop is displayed on the monitors 12 and 14. . Hereinafter, the lyrics telop data 132 and the performance data 13 constituting the music data 130
3 (FIG. 6A) will be described with reference to FIG. M constituting the performance data 133 included in the music data 130 read from the RAM 47 of the commander 20
The IDI data is captured by the sequencer 51 and written to the MIDI sound source 52 according to the count of the timer 53. 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. Then, the output music signal is amplified to the volume set by the amplifier 16 and then output to the speakers 13, 13.
3 and 13 as a performance sound (step 6).
00).

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 the video RAM
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 2,14. (Step 620)

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
7, or sing (karaoke) through the microphone 18.

Then, the CPU 45 determines whether or not the reserved music selection number data is stored in the RAM 47 (step 680), and if it is stored (step 68).
0: Yes), and stores the stored music selection number data in R
Read from AM 47 (Step 700), Step 10
Steps 0 to 680 are executed to reproduce the reserved music.

Next, a modification of the task B shown in FIG. 18 in the first embodiment will be described with reference to a flowchart shown in FIG. FIG. 24 shows a part of the task B, and the steps other than the step 521 are the same as those of the task B shown in FIG. 18, so that the steps other than the steps 521, 522 and 524 are not shown. . In step 520, the remaining reproduction time T
It is determined whether or not 4 is equal to or longer than TG and shorter than 2TG.
Here, TG indicates a reproduction time by one GOP of background video data. That is, in step 520, the remaining reproduction time T4 is equal to or longer than the reproduction time for one GOP and GO
It is determined whether the reproduction time is shorter than the reproduction time of P2.

For example, when the third background video is reproduced according to the reproduction schedule shown in FIG. No. 1 to No. The reproduction of the background video data for seven GOPs up to 7 has been completed. 8 to No. 8 GOP15 up to 22
It is assumed that background video data for a single piece is stored. Also,
As for the cumulative reproduction instruction time T2, it is assumed that the cumulative reproduction instruction time T2 of the synthesis of the first file and the second file is 60 seconds, and the third reproduction instruction time t is 14 seconds.

Then, the new cumulative reproduction instruction time T2 becomes
T2 + t = 60 seconds + 14 seconds = 74 seconds (Step 5
02). Since the reproduction of the background video data for seven GOPs has been completed, the actual reproduction time T1 measured from the start of reproduction of the first file is 60 seconds + 0.6 seconds × 7.
= 64.2 seconds. Further, since the background video data for 15 GOPs is stored in the buffer memory 65, the temporary buffer reproduction time T3 is 0.6 seconds × 1
5 = 9.0 seconds (step 516). Therefore,
The remaining reproduction time T4 is T2−T1−T3 = 74 seconds−6.
4.2 seconds−9.0 seconds = 0.8 seconds. That is, TG
(0.6) ≦ T4 (0.8) <2TG (1.2).

Therefore, the process proceeds to step 522 (step 521: Yes), and the read pointer of the file being reproduced is advanced by one GOP (step 524). Thereby, No. The background video data for one GOP of 23 is read out (step 510) and stored in the buffer memory 65 (step 514).
Minute playback time is added as a temporary buffer playback time T3, and during that time, the background video data is played back, and the actual playback time T1 is also increased. Is less than the remaining reproduction time T4 calculated before reading out at least one GOP (0.6 seconds) or more (step 518).

That is, since T4 calculated in the previous step 518 is 0.8 seconds, T4 calculated in the current step 518 is at least 0.2 seconds (0.8 seconds−0.6 seconds). Step 52
At 1, the determination is negative (step 521: No), and the file is closed (step 524). Thus, the reproduction of the third background video can be ended when the background video data for 23 GOPs has been reproduced. Therefore, there is no possibility that the reproduction is terminated in the middle of the GOP and the background video is disturbed.

As shown in FIG. 8, the actual playback time of the third background video is 13.8 seconds, which is 0.2 seconds short of the playback instruction time of 14.0 seconds. The shortage is added to the actual playback time T1 of the next fourth background video, so that the actual playback time of the fourth file is increased by 0.2 seconds. That is, the shortage of the actual playback time of the third file is added to the actual playback time of the next fourth file. The calculation of the remaining playback time is not carried over. Therefore, since the error between the actual reproduction time of the previously reproduced file and the reproduction instruction time does not shift until the subsequent reproduction, the switching timing between the background videos gradually increases as the reproduction of the background video progresses. Nothing.

Incidentally, in each of the above embodiments, FIG.
The case where the background video is reproduced according to the scheduling indicated by the reproduction method instruction commander 160 shown in FIG. 7D has been described, but the reproduction method instruction commander 1 shown in FIG.
70 or the reproduction method instruction commander 180 shown in FIG. 7F, when the reproduction method of the background video is instructed, similarly to the case of the reproduction method instruction commander 160, the CP
Since the above steps are executed by the U45 and the CPU 64, it is possible to avoid that the reproduction is terminated in the middle of the GOP and the background video is disturbed.

When a plurality of background images are reproduced by the reproduction method instruction commander 180 having a plurality of reproduction instruction data, an error between the actual reproduction time and the accumulated reproduction time becomes large, and the timing of switching the background images becomes large. Large deviation can be avoided. In each of the above embodiments, the DVD provided in the karaoke apparatus as the video playback apparatus of the present invention.
Although the player has been described as a representative, the present invention can also be applied to a CD-ROM player provided in a karaoke apparatus, or a DVD player or a CD-ROM player used other than the karaoke apparatus.

The task B (steps 218 to 524) executed by the CPU 64 functions as the timing control means of the present invention. FIG.
The task B shown in FIG. 24 functions as the timing control means according to the second aspect, and the task B shown in FIG. 24 functions as the timing control means according to the third aspect. Further, the commander 20, the amplifier 16, and the speakers 13, 13 correspond to a music information reproducing unit according to a seventh aspect.

[0122]

As described above, according to the present invention, when the reproduction is terminated between the read timings set for reading the video information, when the video information that cannot be normally reproduced is reproduced, When the actual reproduction time ends between the readout timings, by making the end timings coincide with the readout timings, it is possible to realize a video reproduction apparatus that can normally reproduce video information.
