As described above, the CM between music pieces includes information such as a video clip of a new music piece and a concert guide. However, some CMs between music pieces have restrictions on the period in which they can be reproduced. Therefore, in this karaoke apparatus, a CD-ROM for a CM between songs is used.
Also, the reproduction period information of the CM between songs is downloaded from the distribution center 9 and the information to be reproduced is selected based on the downloaded information. Here, it is conceivable to directly write the reproduction period information on the CD-ROM for the inter-song CM,
At the time of producing a CD-ROM for inter-song CM, the period for reproducing each piece of information is often undetermined.
Cannot write to D-ROM. In addition, since the tour dates for national tours and the like vary from place to place for performance, CD-ROMs for inter-song CMs are supplied to karaoke machines nationwide.
Cannot store the reproduction period information of each place. Therefore, in this karaoke apparatus, the reproduction period information is downloaded from the distribution center 9 after the production of the CD-ROM.

The music data storage area has a capacity to store music data for about 10,000 songs. The program storage area stores the system programs, application programs, and the like. As shown in FIG. 3, the reproduction period management file is a CD-RO for inter-song CM released so far.
The reproduction period of M is recorded for each volume (CD-ROM) and each file (inter-song CM data) stored in the volume.

The communication control unit 16 is connected to the distribution center 9 via an ISDN line. From the distribution center 9, music data, the reproduction period management file, and the like are downloaded. The downloaded data is written to the hard disk storage device 17. This writing operation is directly performed on the hard disk storage device 17 using the DMA circuit.

The distribution center 9 periodically calls the karaoke apparatuses nationwide, downloads music data having contents suitable for each karaoke apparatus via a telephone line (an analog line or a digital line), and downloads the karaoke apparatuses. Download the playback period management file according to the installation area.

The remote controller 8 is provided with key switches such as numeric keys, and when a user operates these switches, a code signal corresponding to the operation is output by infrared rays. The remote control receiving unit 13 receives the infrared signal sent from the remote control device 8, restores the code signal,

The moving image video data is selected based on the video selection data input from, and the moving image video data is reproduced as a background image. The video selection data is determined based on genre data or the like written in the header of the music data. The display control unit 21 combines a character pattern such as lyrics input from the character display unit 20 with a background image and displays the synthesized image on the monitor 6.

In the karaoke apparatus having the above configuration, when a karaoke song request is made, the music data of the request is stored in the hard disk storage device 17 or the CD-ROM.
A search is performed to determine which of the CD-ROMs set in the changer 4 is stored, and the music data is read from the corresponding storage medium. Then, the sound source device 18 and the audio data processing unit 19 are set up, and after instructing the CD-ROM changer 4 to reproduce the background image, the performance of the karaoke music is started. When there is no request for a karaoke song, CM or BGM between songs is reproduced according to the procedure of FIG.

FIG. 2 is a configuration diagram of a CD-ROM for a CM between music pieces. A volume header is provided at the head track of the disc, and the volume name (for example, “CM May 1997 issue”) and the release date are written in the volume header. And CM between songs
Each file consists of a header and a data body. In the file header, a file name, a production date, and the like are written, and the data itself is composed of moving image data, text data, performance data (MIDI data), sound announcement data, and the like. This data structure is almost the same as the music data for karaoke music performance. The moving image data is synthesized with the text data and displayed on the monitor 5, the performance data is played by the sound source device 18, and the sound announcement data is the audio data. It is reproduced by the processing unit 19.

However, even after a new inter-song CM CD-ROM is released, the old inter-song CM CD-ROM can be reproduced as it is until the end of the reproduction period. At the end of the playback period of a CD-ROM,
What is necessary is just to make it coincide with the end of the reproduction period of the CM data for all songs included in the ROM. By doing so, FIG.
In the above operation, it is possible to avoid a situation in which after searching for the reproduction periods of all files, it is found that there is no CM between songs that can be reproduced.

The reproduction period information of this embodiment is information for directly instructing the end of the period during which reproduction is permitted, as in the case of 月, 日 の, but the reproduction period information includes the start of the period during which reproduction is permitted. Alternatively, both the start and end of the period during which reproduction is permitted may be instructed. FIG. 4 is a flowchart showing a CM-to-song CM reproduction operation of the karaoke apparatus, which may be instructed as indirect information for determining a date of a period during which reproduction is permitted. FIG. 3A shows a monitoring operation for monitoring the operation of the karaoke apparatus. In this operation, it is checked at regular time intervals whether a karaoke song is currently being played (s
1). If a karaoke song is being played, there is no room for reproducing the inter-song CM, so the process returns. If no karaoke song has been played and there is no request, a CM-between-song execution operation (FIG. 8B) is started (s2). This operation is continued until there is a new request (s3), and if there is a request, the currently executing inter-song CM execution operation is interrupted (s4) and the operation shifts to a karaoke performance processing operation.

FIG. 3B is a flowchart showing the operation for executing the CM between music pieces. First, it is determined whether a CD-ROM for a CM between music pieces is set in the CD-ROM changer 4 (s10). If the CD-ROM for inter-song CM is not set, the default BGM is reproduced (s1).
5). The default BGM reproduces BGM music data having the same specifications as the music data of the karaoke music.

If the CD-ROM for the inter-song CM is set in the CD-ROM changer 4, the CD-R
It is determined whether or not the OM has passed the reproduction period (s11). If the playback period has passed, the process proceeds to the default BGM playback operation (s15). In the case of a CD-ROM during the reproduction period, CM data between songs stored in the CD-ROM is sequentially selected (s12).
Playback is performed (s14). At this time, it is determined from the contents of the playback period management file whether or not the playback period has elapsed for each CM between songs (s13). If the playback period has elapsed, the data is skipped and the next data is replaced. A selection is made (s13 → s12).

As described above, first, the reproduction period of the CD-ROM is determined, and the contents of the CD-ROM whose reproduction period has passed are immediately checked without checking the contents, so that the default BGM reproduction operation can be performed. It is not necessary to check all the reproduction periods of the CM data between music pieces. In addition, by setting a playback period for each file, even if various information such as a concert guide or a video clip of a new song is recorded, a playback period is set for each information content and played back to an appropriate time. can do.

FIG. 5 is a flowchart showing the download operation of the distribution center and the karaoke apparatus. The distribution center 9 transmits a list of music data registered in the center by calling each karaoke device, which is a terminal device, at regular intervals of about twice a month (s20). The karaoke apparatus receives the music data list (s30), and extracts the missing music in comparison with the music data list stored in the hard disk storage device 17 of the karaoke apparatus (s30).
31). Then, the list of the missing songs is returned to the center (s32). The distribution center 9 receives the list of the missing songs (s21), and downloads the song data of the songs described in the list to the karaoke device (s2).
2). The karaoke apparatus receives the music data of the missing music (s33) and additionally stores it in the music data storage area of the hard disk storage device 17 (s34).

The center then proceeds to the CD-R for inter-music CM.
The OM playback period management file is transmitted (s23). The karaoke apparatus receives this list (s35), and updates the reproduction period management file stored in the hard disk storage device with the newly downloaded file (s36).

As described above, since the reproduction period management file is downloaded from the distribution center, it is not necessary to know the reproduction period when producing the CD-ROM, and it is easy to change later. In addition, by downloading a different playback period for each region, for example, in the case of a concert that tours the whole country, the playback period can be set in accordance with the performance date in that region.

In the above embodiment, the reproduction period control of the inter-song CM reproduced between the karaoke songs has been described. However, the background video displayed on the monitor 5 together with the lyrics telop during the performance of the karaoke song is also described. This reproduction period control can be applied. By applying the reproduction period control, it is possible to reproduce a video that matches a season or time, for example.

Also, in the above embodiment, an example was described in which a CD-ROM was used as a medium for storing video data.
Any storage medium such as an MD or a DVD may be used.
Further, a non-removable hard disk storage device can be used. In this case, the video data may be downloaded from the distribution center.

[0040]

As described above, according to the present invention, whether or not video data supplied from a storage medium or video data downloaded in advance is reproduced based on reproduction period information is restricted. Thereby, the video data produced in advance can be reproduced at an appropriate time.

Further, since the reproduction period information is downloaded from the distribution center, the reproduction period can be determined and changed after the storage medium is supplied to each karaoke apparatus. A playback period can also be set.
