(1) Video screen and information (information name of main information) showing table of contents information showing the titles of all recorded songs. (2) Barcode song title identification code: Displayed after the song title in the table of contents information. The song title identification code is indicated by a barcode.

(3) Table of contents static information (screen static information): Information that instructs the video disc player to play the video screen representing the table of contents information on a still screen, and is video signal vertical synchronization of the video screen information representing the table of contents information. It is multiplex recorded in the signal part.

(4) Video screen information (main information) on which lyrics are multiplexed (
5) Song title identification information; corresponds to the barcode song title identification code, and is multiplexed recorded in the video signal vertical synchronization signal portion of the video screen information.

Further, 3 is a light pen for indicating a desired song among the song titles displayed on the CR7 screen 10, 4 is a disc player main body, and in this player main body 4, 4a is a high speed search for the video disc 2. A prefectural circuit 4b compares the obtained song title identification information with the barcode specified by the light pen 3, and outputs a playback command signal when they match, and 4b is a circuit for karaokeing a desired song upon receiving this playback command signal. This is a playback circuit that plays.

Next, the operation will be explained.

When the operator puts video disc 2 on the video disc player, all the contents recorded on video disc 2 are displayed.
That is, the table of contents information appears as a static screen on the TV screen. The drawing shows an example of this situation, and from the left, the song numbers 2, 2 song names 11a and llb are shown, and finally the bar code 12a.

The song identification code is shown at 12b. That is, the first song has the 1i1i different code 12a, and the second song has the 241st code.
1i separate code 12b is shown, and the identification codes of all the songs are shown in order by barcodes.

Here, the karaoke operator traces the barcode 12 of his/her favorite song with the provided light pen 3 and presses the "play button" provided on the light pen 3. Then, the song name identification information on the video disc 2 is searched at high speed, and each piece of identification information is compared with the bar code indicated by the light pen 3 on the identification chart 4a. When the two match, that is, when the beginning of the song is completed, the identification circuit 4a
A playback command signal is output from the playback circuit 4b that receives the playback command signal, and the playback circuit 4b reproduces a desired song, raoke song, etc. By using the karaoke video disk device according to this embodiment, The operator's work is very simple and simple: tracing the barcode with a light pen and pressing a small button on the light pen.Therefore, the karaoke operator does not have to look at the song book or jacket. , it is possible to enjoy karaoke with just one light pen, and it is clear that such a device is useful for highly entertaining karaoke.

In the above embodiment, special song name identification information corresponding to the barcode song name identification code is attached to each song, but the above-mentioned frame number information can also be used as this song name identification information, and in this case, , information corresponding to the frame number representing the screen number at the beginning of the song may be used as the barcode song title identification code.

Next, an embodiment of the second invention of the present application will be described. The second invention of the present application is particularly useful for video discs for encyclopedias, and its configuration is almost the same as that described in the first invention of the present application above. The difference between the two lies in the content stored on the video disc 2. In the case of this embodiment, the video disc 2 includes main information having a plurality of chapter information each consisting of a plurality of section information.

Chapter table of contents information and corresponding barcode information.

Table of Contents information and corresponding barcode information for the sections recorded in each car, screen still information for playing still images of each of the above table of contents information, and chapter 2 section identification information corresponding to each of the above barcode information. Information is recorded.

The operation is almost the same as the above embodiment, and by tracing a desired barcode in the table of contents information displayed on the screen with a light pen and pressing the play button of the light pen, the barcode is matched with the above barcode. The child or section identification information is quickly searched, and the desired chapter or section information is thereby reproduced. Therefore, if you use Kemio's encyclopedia video disc, you will be able to operate it without a table of contents guide, and its practicality will be significantly improved. However, in this case, due to screen limitations, it is preferable that the table of contents displayed at the beginning be a chapter-by-chapter table of contents.If you select the desired chapter from this children's table of contents, a section-by-section table of contents will be displayed at the beginning of that chapter. It is clear that the usefulness will be further increased if the structure is configured as follows.

In this embodiment as well, of course, the frame number may be used as the chapter 1 identification information.

C. Effects of the Invention] As described above, according to the present invention, table of contents information consisting of the information name of each information and barcode information corresponding thereto is recorded on a video disc, and a part of each information is provided with identification information.
