[0002]
[Prior art]
A service has been proposed in which karaoke users have their own IC card and the IC card is used (JP-A-8-6578, etc.). This IC card stores personal karaoke related information data such as music selection history, performance conditions, and scoring history. The karaoke user inserts his / her IC card into a reading / writing device attached to the karaoke device to read karaoke related information data.
[0003]
As a result, as shown in FIG. 2, the song name that is always requested is displayed on the display. In this example, song names are arranged from the top in descending order of the number of songs selected. Then, you can easily select a song by operating the cursor button on the remote control and specifying the name of the song you want to sing. When playing, the playing conditions such as keys and tempo are displayed. When you actually sing, you will be scored, and that will be the new average added to your past scores. The number of songs selected is also added.
The latest karaoke related information data as described above needs to be updated in each IC card.
[0004]
[Problems to be solved by the invention]
How to update karaoke related information data in this IC card is a problem. The IC card must be inserted into the reading / writing device from the time the karaoke related information data is read until the performance of the requested song and the scoring is completed and the data is updated.
[0005]
However, in karaoke boxes, many karaoke users want to make requests to us. That is, if a certain karaoke user inserts an IC card and reads his / her own karaoke related information data, it must be extracted immediately.
If the karaoke-related information data is inserted until it is updated without being extracted, other karaoke users will not be able to insert the IC card, and the song selection operation and karaoke performance will be delayed. .
[0006]
The present invention has been made in order to solve such problems, and its purpose is to provide karaoke-related information data of a portable recording medium without delay in music selection operation and karaoke performance using the portable recording medium. Is to update.

DETAILED DESCRIPTION OF THE INVENTION
==== Karaoke performance function ====
The music reproduction by the karaoke apparatus 1 is performed as follows under the control of the central processing unit 11, as shown in the block diagram of FIG. The karaoke user operates the remote control transmitter 24 or the operation panel 17 to input the music number. Accompanied music data and lyrics data of the input music number are read from the hard disk device 20. Accompaniment music data consisting of MIDI signals are sequentially input to the synthesizer 14 and converted into audio signals. This audio signal is mixed with the output of the microphone 21 by the mixing amplifier 15 and output from the speaker 23.
In synchronization with this audio output, the central processing unit 11 sequentially converts the lyrics data into a character string and writes it into the video RAM 13. At the same time, a process of adding a color change indicating the progress of the song to the lyrics character string is performed. The contents of the video RAM 13 are displayed on the display 22 by the display control unit 12.
[0011]
The moving image information for the background video is reproduced by the CD-ROM player 25. The display control unit 12 performs selection processing of video data to be played back and plays back the determined video data on the CD-ROM player 25. Then, the display control unit 12 combines the video signal from the CD-ROM player 25 and the image of the lyric character string in the video RAM 13 and displays them on the display 22.
As accompaniment music data to be reproduced, in addition to the above-mentioned MIDI signal, MPEG data obtained by digitally compressing and accompaniment music can also be used. In the MPEG data, lyrics data and video data are also multiplexed. The video data is a compression-encoded mood image having contents adapted to each karaoke piece.
[0012]
This MPEG data is stored on a DVD (digital video disk). Each data is read out by the DVD player 28, decompressed and decoded, and separated into lyrics data, audio data and video data. Then, the lyrics data from the DVD player 28 is input to the central processing unit 11. At the same time, the video data is input to the display control unit 12, and the audio data is input to the mixing amplifier 15. Each of these data is output from the display 22 and the speaker 23 through substantially the same processing as that of the MIDI signal described above.
[0013]
==== Karaoke service using IC card ====
<< Overview >> In the karaoke apparatus of the present invention, an IC card reading / writing device 60 is connected to the central processing unit 11 as shown in FIG. A karaoke user inserts his IC card 70 into the IC card reading / writing device 60. Then, the central processing unit 11 reads the recorded karaoke related information data together with the card ID and temporarily stores it in the hard disk device 20.
These IC card 70 and IC card reading / writing device 60 are well-known configurations. The karaoke related information data is the same as the conventional case described above as shown in FIG.
The read IC card 70 may be inserted as it is, but can be removed for insertion of the IC card 70 by other karaoke users.
[0014]
The central processing unit 11 executes a karaoke service described later based on the karaoke related information data temporarily stored in the hard disk device 20. At this time, the karaoke related information on the hard disk device 20 side is updated according to the execution result of the karaoke service. The old karaoke related information on the IC card 70 side is updated when the IC card 70 is reinserted into the IC card reading / writing device 60 later.
[0015]
<< Specific Operation Example >> A description will be given with reference to the flowchart of FIG. When the IC card 70 is inserted into the IC card reading / writing device 60, the card ID and karaoke related information data are read, and the central processing unit 11 determines whether karaoke related information data of the same card ID exists in the hard disk device 20. Confirm (S10 → S20 → S30). If not, the karaoke related information data is copied to a predetermined storage area of the hard disk device 20 in association with the card ID (S30 → S40). If it exists, the karaoke related information data on the hard disk device 20 side is updated by copying it to the IC card 70 side (S30 → S50).
When the update process on the IC card 70 side is completed, the corresponding karaoke related information data on the hard disk device 20 side may be deleted. As a result, the karaoke related information data that has been copied to the IC card 70 does not remain unnecessarily on the hard disk device 20 side.
[0016]
When such a copy process is completed, the process of reading or writing to the IC card 70 is not performed unless it is newly inserted into the IC card reading / writing device 60 (S60). Even if the IC card 70 is removed from this point, since the karaoke related information data is copied to the hard disk device 20 side, it can be reinserted and updated later.
Then, as shown in the table of FIG. 2 described above, the central processing unit 11 displays the read karaoke related information data as a music selection list on the display 22 and accepts a request from a karaoke user. When the request is received, the karaoke related information data on the hard disk device 20 side is updated (S70 → S80 → S90). Specifically, the karaoke related information data to which the new music selection content is added is overwritten on the hard disk device 20. Further, when the requested music is actually played, the new karaoke related information data to which the performance condition and the average score are added is overwritten on the hard disk device 20. At the end of the performance, the music selection content, performance conditions, and scoring results may be updated together.
[0017]
If the IC card 70 is not removed at this time, it is determined that there is no request from another karaoke user, and the music selection list of FIG. 2 based on the updated karaoke related information data is displayed again on the display 22 (S100 → S70). . At this time, the karaoke related information data on the IC card 70 side may be updated. If the IC card 70 has been removed, it waits for insertion of the IC card 70 (S100 → S10).
[0018]
If no request is made after displaying the music selection list, it is confirmed whether the IC card 70 has been removed (S70 → S80 → S110). If it has not been extracted, it means that there is no music selection by another karaoke user, and the request is kept as it is (S110 → S80). If the IC card 70 has been removed, it is determined whether or not to cancel the process of displaying the music selection list and accepting the request based on the music selection list (S110 → S120). If a stop signal is not sent from the remote control transmitter 24 by the operation of the karaoke user, the request is waited while the music selection list is displayed (S120 → S80). When a stop signal is sent, the karaoke related information data of the corresponding card ID on the hard disk device 20 side is erased, and a new insertion of the IC card 70 is awaited (S120 → S130 → S10).
[0019]
In this case, the karaoke related information data is not updated because there is no request and the IC card 70 is removed and the operation for canceling the music selection is performed. Therefore, there is no problem even if the karaoke related information data of the corresponding card ID is deleted from the hard disk device 20.
Note that the determination of canceling the request acceptance process in S120 may be omitted, and only the IC card 70 may be removed as a condition.
[0020]
If the karaoke user forgets to insert the IC card 70 again and perform the update process, the updated karaoke related information data on the hard disk device 20 side cannot be copied to the IC card 70 side. However, the content of the karaoke related information data is not related to a usage fee or a coupon service, but is a music selection content or a history of karaoke performance. For this reason, it will not be a big problem.
[0021]
By the way, when the karaoke related information data in the hard disk device 20 is not erased and remains for several days, a problem of miscopying occurs. After the karaoke user uses another karaoke device and the karaoke related information data on the IC card 70 side is updated, the old karaoke related information remaining in the hard disk device 20 when the karaoke device used before is used again. Data is overwritten on the IC card 70 side.
[0022]
It is necessary to take measures to prevent such miscopying. After the karaoke related information data is read from the IC card 70 and written to the hard disk device 20, the karaoke related information data is deleted after a sufficient time has elapsed. Erase as the initial process when the karaoke machine is powered on.
[0023]
Alternatively, the karaoke-related information data may be deleted on the hard disk device 20 after a predetermined time (for example, 24 hours). Alternatively, the updated karaoke related information data on the hard disk device 20 side may be erased after a predetermined elapsed time from copying to the IC card 70. Of course, those not updated are also deleted after a predetermined elapsed time.
The timing of erasing and the timing for calculating the elapsed time can be appropriately changed as long as miscopying can be prevented.
Due to this miscopying countermeasure, it is possible to avoid a situation in which the karaoke related information data of the hard disk device 20 is excessively accumulated.
[0024]
==== Other ====
(A) In addition to the IC card 70, a portable recording medium that can be appropriately replaced, such as a magnetic recording medium or an optical recording medium having a configuration similar to that of a telephone card or an optical card, can be applied to the present invention. In this case, the magnetic card reading / writing device 61 and the optical card reading / writing device 62 shown in FIG.
(B) As a means for temporarily storing karaoke related information data, in addition to the hard disk device 20, a memory that can be appropriately replaced can be applied to the present invention.
(C) A measure may be taken to prevent forgetting to insert the IC card 70 for renewal by a karaoke user.
For example, if the IC card with the corresponding card ID is not inserted within a predetermined time (about 20 minutes) after the karaoke-related information data on the hard disk device 20 side is updated, “Please enter it” message is displayed in one corner of the display 22.
(D) The operation of updating the karaoke related information data on the hard disk device 20 side in accordance with the actual music selection operation or karaoke performance after reading the karaoke related information data from the IC card 70 can be changed as appropriate. It is not restricted to the operation example of this flowchart.
[0025]
【The invention's effect】
A music selection process or the like is performed based on the karaoke related information read from the portable recording medium, and the result is temporarily updated and stored in a predetermined information area in the attached storage device. Later, when the portable recording medium is inserted again, the updated karaoke related information is read from the information area, and the karaoke related information on the portable recording medium side is updated. For this reason, the portable recording medium can be extracted when the karaoke related information is read out, and can be updated later even if another karaoke user inserts the portable recording medium.
[0026]
Therefore, until the karaoke-related information is updated according to the use of karaoke, the portable recording medium remains inserted in the reading / writing device, and the portable recording medium of another karaoke user cannot be inserted. The trouble can be solved.
For this reason, music selection operations and karaoke performances using IC cards by a plurality of karaoke users are smoothly performed.
[0027]
After a sufficient time has elapsed since the writing process for the information area, the relevant karaoke related information is deleted. As a result, when the karaoke user uses another karaoke device and the karaoke-related information data on the portable recording medium side is updated, when the karaoke device used before is used again, it remains in the storage device. This prevents the old karaoke related information data from being overwritten on the portable recording medium.
