1 is a block diagram showing an embodiment of a karaoke apparatus of the present invention. In the figure, 1 and 2 are stockers and 3
Is a CD reproducing device, 4 is a CD-ROM reproducing device, 5 is a system control device, 6 is a non-volatile memory device, 7 is a switch, and 8 is an operating device. In this embodiment, a CD is used as a recording medium on which audio information is recorded, and a CD-ROM is used as a recording medium on which image information is recorded.

In the stocker 1, voice information of a plurality of songs,
The n CDs in which the audio genre codes indicating the types of the audio information are recorded in the sub code area are stored. Each CD has a series of disc numbers. For a predetermined CD, for example, a CD with a disc number n, the genre code of the disc number n and the genres of all the songs contained in the CDs of the disc numbers 1 to n stored in the stocker 1 The code is recorded.

The stocker 2 accommodates m pieces of CD-ROMs in which a plurality of pieces of image information and genre codes of images indicating the types of the image information are recorded. A series of disc numbers is assigned to each CD-ROM. Predetermined CD-ROM, for example, C of disc number m
In the D-ROM, the disc number 1 is stored in the stocker 2 together with the genre code of the disc number m.
The genre codes of all the image information mainly recorded on the CD-ROM from the disc number m to the disc number m are recorded.

The CD reproducing device 3 follows the instructions of the system control device 5 and stores a plurality of CDs stored in the stocker 1.
One of them is selected, and the specific audio information in the selected CD is reproduced and output. Further, the information recorded in the subcode area in the CD is read and output to the non-volatile memory device 6. The CD-ROM reproducing device 4 selects one from a plurality of CD-ROMs stored in the stocker 2 according to an instruction from the system control device 5 and reads out specific image information in the selected CD-ROM. , Output as image data. Further, the genre code recorded in the CD-ROM is read and output to the non-volatile memory device 6.

The system control device 5 controls the entire device and reproduces the voice information and the image information of the music designated by the operating device 8 based on the genre code stored in the non-volatile memory device 6. CD player 3, CD-R
The OM reproducing device 4 is instructed. Further, on the basis of an instruction from the operation device 8, the process of reading all the genre codes at the time of installation and storing them in the non-volatile memory device 6 and adding or changing the genre codes are controlled. The nonvolatile memory device 6 includes a genre code of a CD stored in the stocker 1 and a CD-stored in the stocker 2.
Stores the genre code in ROM. Since it is composed of a non-volatile memory, it retains information even when the device is powered off. Therefore, if the genre code is stored at the time of installation, it can be used at any time thereafter.
The operation device 8 instructs registration, addition, change, etc. of the genre code, and selects and inputs a music piece to be reproduced. Switch 7
Is controlled by the system controller 5 and is a CD-ROM
The output from the playback device 4 is switched between image data output and non-volatile memory device 6.

In the above-mentioned structure, in the CD reproducing apparatus 3, since the audio data is recorded in the main data string area, it is outputted separately from the subcode data recorded in the sub data string area. Since the image data to be output and the genre code data are data in the main data area, the CD-ROM reproducing device 4 outputs these data to the same output line and switches them by the switch 7. However, when the audio data output from the CD reproducing device 3 is digital data, a switching means such as a switch may be used. When the image data output from the CD-ROM reproducing device 4 is analog data, that is, a video signal, a signal line different from the genre code may be used.

FIG. 2 is an explanatory diagram showing an example of the format of the subcode data on the CD. The sub code data is code data recorded in a sub data string area for recording audio information of a CD. The access is performed by designating the song number, as in the case of normal song selection. For example,
The genre code data of the songs in this CD is recorded as the first song subcode data, the changed genre code data is recorded as the second song subcode data, and the genre codes of the songs in all CDs are recorded as the third song subcode data. Recording such as recording data is possible. When such recording is performed, the subcode data of the first song may be read in when additionally registering the voice genre code, and the subcode data of the second song may be read in when registering the change of the voice genre code. When all the voice genre codes are registered, the sub-code data of the third piece of music may be controlled to be read.

The subcode data is composed of a plurality of subcode frames. One subcode frame is
Includes 4 packs. FIG. 2A shows an example of the data format of one pack. In this example,
One pack is composed of 6 × 24 (bit). In the pack, pack serial number, audio disc number,
The number of songs, the song number, the audio genre code, the control code, etc. are recorded. By reading this one pack, it is possible to obtain the information of the audio disc number, the song number, and the genre code for one song, which is necessary for reproduction.

The pack serial number is a serial number assigned to identify each piece of information. Audio disc No
Is the disc number of the CD. The control code indicates, for example, that all 0s indicate the continuation of data in the next pack, and all 1s indicate that the data is the end.

As for the data of each pack, as shown in FIG. 2B, the same data is continuously recorded for 8 packs or more, that is, for 2 subframes or more. Here, G is subtitle information used for karaoke, and of course, it does not matter. The packs serially recorded have the same pack serial number. This is because the subcode data is recorded in the subdata string area, so the reading accuracy is poor,
Since the occurrence rate of errors is high and the functions of synchronization detection, error detection, and correction means are low, such a configuration is provided in order to prevent missed reading. Pack serial number
Is used for error checking to prevent missed reading. If a missed reading is detected, retry is performed. Of course, the number of repetitions of the same data may be less than 8 packs, but it is necessary to expect the occurrence of an error accordingly.

FIG. 3 is an explanatory diagram of an example of the genre code recording format in the CD-ROM. CD-R
Since the OM generally uses a recording method that can handle digital data, the genre code can be recorded based on a general data file recording method. Therefore, unlike the subcode data of CD, it is not recorded repeatedly eight times. However, it is also possible to record about two or three copies and prepare for a read error.

In the CD-ROM, a portion corresponding to the directory is, for example, as shown in FIG.
-Start address of genre code data corresponding to image file in ROM, start address of changed data, all Cs
The start address of the genre code data of the image file in the D-ROM, the number of image data in this CD-ROM,
The start address of each image file can be stored. The address here is this CD-ROM
The position where the information is recorded is shown.

The genre code data corresponding to the image information recorded in one CD-ROM is shown in FIG.
As shown in FIG. 5, the CD-ROM disc number, the number of recorded image files, and the genre code of each image file are arranged. As shown in FIG. 3C, the genre code data relating to the change data includes the change disc number, the change disc number, the number of image files, and
The sequence of genre codes for the number of image files is repeated for the number of changed disks. Further, as shown in FIG. 3D, the genre code data of the image files in all the CD-ROMs is such that, as shown in FIG. Repeated a number of times. In each data string, the genre codes can be recorded in the order of the image file numbers, for example.

When the genre code is recorded with such a structure, when adding the genre code of the image, from the head address of FIG. 3 (A) to that of FIG. 3 (B).
CD-ROM according to the data format shown in
The genre code of the image file recorded therein is read and additional processing is performed. When changing and registering the genre code of an image, the change data is read from the second address in FIG. 3A in accordance with the data format shown in FIG. 3C, and the change registration process is performed. When all the genre data of the image is registered, FIG.
The genre data of all image files recorded on a plurality of CD-ROMs is read from the third address in (A) according to the data format shown in FIG. 3D, and the registration process is performed.

The above-mentioned data recording format of the CD and the CD-ROM is an example, and it is obvious that other formats may be used for recording. Further, the genre data corresponding to the audio information and the image information recorded in all the CDs and all the CD-ROMs may be registered in the predetermined CDs and the predetermined CD-ROMs.
-It need not be registered in ROM. The genre data and the change data corresponding to the audio information or the image information recorded in each CD or each CD-ROM may be omitted if addition or change is not performed.

FIG. 4 is an explanatory diagram of an example of data stored in the non-volatile memory device 6. Non-volatile memory device 6
Stores the genre code of the audio information read from the CD and the genre code of the image information read from the CD-ROM. The genre code of audio information is shown in Fig. 4.
As shown in (A), information for each CD is repeatedly stored after the number of CDs. As information for each CD, a column of the number of songs and a genre code of each song is stored. The genre code sequence can be arranged in the order of music numbers. If they are not in the order of the song numbers, the song numbers and the genre codes may be paired and stored.

The genre code of the image information is almost the same as the genre code of the audio information, as shown in FIG.
As shown in, after each CD-ROM,
Information for each ROM is repeatedly stored. Each CD-
The information for each ROM stores the number of image files and a column of genre codes of each image file. The genre codes can be arranged in the order of file numbers of image files. Of course, the file number and the genre code may be stored as a pair.

In FIG. 4, the information regarding each genre code is shown sequentially for convenience of illustration, but the present invention is not limited to this, and various data formats such as a list structure using pointers can be used.

The operation of one embodiment of the karaoke apparatus of the present invention will be described with reference to FIGS. 1 to 4 and FIGS. 5 to 6. FIG. 5 is a flow chart for explaining the operation of genre code registration in one embodiment of the karaoke apparatus of the present invention. In the operation device 8, when the registration type switch is pressed in S11, the genre code type switch is pressed in S12, and the disk number is selected and input in S13, the respective processes are executed. Registration types include addition, change, and all registration. The genre code type includes audio and image types.
As for the disc number, in the case of all registration, the disc number in which the genre codes of all the discs are recorded is input. If the discs on which the genre codes of all the discs are recorded are predetermined, it is not necessary to input the disc numbers in S13. Further, the input of S11 and S12 may be performed by one key operation.

Now, when the switch for disc number n and all voice genre code registration is pressed on the operating device 8, S1
4, the system control device 5 causes the CD playback device 3 to record the audio genre codes of all the songs from the disc number 1 to the disc number n recorded in the subcode of the CD of the disc number n of the stocker 1. Instruct to play. In S15, the CD player 3 reads out the genre codes corresponding to all the songs,
The genre code is recorded in the nonvolatile memory device 6 together with the disc number and the song number. When the genre codes corresponding to all the songs are recorded as the subcode data of the third song, for example, the subcode data can be read by designating the song number of the third song.
Then, the information in the pack shown in FIG. 2 is extracted from each subcode data, and the genre code, disc number,
You can get the song number. This information is recorded in the non-volatile memory device 6. This operation is repeated until the control code in the pack indicates the end. Further, in S16, the number of CDs is recorded in the nonvolatile memory device 6.

Next, when the disk number m and the switch for registering all image genre codes are pressed on the operation device 8, S1 is entered.
7, the system controller 5 closes the switch 7 to the side of B, and discs from the disc number 1 to the discs recorded on the CD-ROM of the stocker 2 of the disc number m with respect to the CD-ROM reproducing device 4. An instruction is issued to reproduce the genre codes of all image information up to the number m. In S18, the CD-ROM reproducing device 4
Reads the genre code corresponding to all the image information and records the genre code in the nonvolatile memory device 6 together with the disc number and the image information number. For example, if the data is recorded in the format shown in FIG. 3, the data string shown in FIG. 3D is read based on the third address shown in FIG. 3A, and the genre code and disc number are read. , The image file number is obtained, and these pieces of information are recorded in the nonvolatile memory device 6. In S19, the CD-RO
The number of M sheets is recorded in the nonvolatile memory device 6.

The registration setting of the genre codes for all the discs stored in the stocker 1 and the stocker 2 is completed by the above-described processing of all registration of the audio genre code and all registration processing of the image genre code. These two processes may be performed separately,
Alternatively, both processes may be continuously performed by one key operation.

A case will be described below in which the (n + 1) th disc or the (m + 1) th disc is newly distributed and added to the stocker at a later date. First, when a CD in which audio information is newly recorded is added to the (n + 1) th CD, a switch for disc number n + 1 and additional audio genre code registration is pressed by the operation device 8. In S20, the system control device 5 reads only the genre code corresponding to the music recorded on the CD from the CD of the disc number n + 1. Then, in S21, the read genre code is additionally recorded in the non-volatile memory device 6 together with the disc number and the song number. For example, when the genre code corresponding to the music stored in each CD is recorded as the subcode data of the first music, the first music is selected. And until the control code in the pack indicates the end,
The genre code, disc number, and song number to be added are obtained from the read subcode data and recorded in the non-volatile memory device 6. Further, in S22, the number of CDs in the non-volatile memory device 6 is counted up.

CD-ROM on which image information is newly recorded
Is added to the (m + 1) th sheet, the switch for disc number m + 1 and additional image genre code registration is pressed on the operation device 8. In S23, the system controller 5
From the CD-ROM with disk number m + 1 to the CD
Read only the genre code corresponding to the image information recorded in the ROM. Then, in S24, the read genre code is additionally recorded in the non-volatile memory device 6 together with the disc number and the song number. For example,
The data string shown in FIG. 3B is read based on the first address in FIG. 3A, the genre code, disc number, and song number of the image file in the CD-ROM are obtained, and the nonvolatile memory device 6 To record. In S25, the number of CD-ROMs in the non-volatile memory device 6 is counted up.

Further, among the discs stored in the stocker 1 or the stocker 2, i discs may be replaced at a later date. At this time, information such as the genre code associated with the change can be collectively recorded on the j-th disc. I C with audio information recorded
When D is exchanged and the information is recorded on the j-th CD, the operation device 8 presses the switch for disc number j and audio genre code change registration. In S26, the system control device 5 reads the recorded changed genre code data from the exchanged CD of the disc number j. Then, in S27, the genre code data stored in the nonvolatile memory device 6 is rewritten with the read genre code data. For example, when the changed genre code data is recorded as the sub code data of the second music, the second music is selected,
The genre code, disc number, and song number to be changed are obtained from the obtained subcode data, and the data of the corresponding genre code recorded in the nonvolatile memory device 6 is rewritten. This operation is repeated until the control code in the pack indicates the end.

I-sheet CD-ROM on which image information is recorded
Is exchanged and the information is recorded on the j-th CD, the operation device 8 presses the switch for disc number j and image genre code change registration. In S28, the system controller 5 changes the replaced disk number j.
The recorded changed genre code data is read from the CD-ROM. Then, in S29, the genre code data stored in the nonvolatile memory device 6 is rewritten with the read genre code data. For example, the data string shown in FIG. 3C is read based on the second address in FIG. 3A, and the genre code, disc number, and song number of the changed image files in the CD-ROMs of i sheets are read. Then, the data of the corresponding genre code recorded in the nonvolatile memory device 6 is rewritten.

The changed genre code can be recorded in each existing disc from the beginning. At this time, the changed genre code recorded on each disc is different. Then, an arbitrary disc number is selected, and audio genre code change registration and image genre code change registration are performed. As a result, each song and the image corresponding to it can be changed. The user can select a combination of a song and an image that suits his or her preference, and can display a different image even when the same song is reproduced.

FIG. 6 is a flow chart showing an example of the operation of the karaoke apparatus of the present invention during karaoke performance. When playing karaoke, the disc number and the song number of the CD in the stocker 1 are selected from the operation device 8 in S31. Here, for the sake of explanation, for example, it is assumed that the disk number 150 and the music number 3 are selected. In S32,
The system controller 5 searches the non-volatile memory device 6 for the genre code data of the audio information, and the disc number 1
Check the genre code of the voice information of 50 and song number 3.
In S33, the disc number of the CD-ROM in the stocker 2 and the image file number that match the genre code of the sound information that was examined are searched for from the genre code data of the image information in the non-volatile memory device 6. As a result, for example, it is assumed that the image disc number 20 and the image number 5 are selected. When there are a plurality of pieces of image information to which the same genre code is added, one of them is selected using, for example, a random number.

Then, in S34, the system controller 5 closes the switch 7 to the side of A and, with respect to the CD player 3, the disc number 15 in the stocker 1
Instruct to play song number 3 recorded in 0,
In addition, for the CD-ROM playback device 4, the stocker 2
It issues an instruction to reproduce the image number 5 recorded on the disc number 20 in the inside.

When the reproduction is started, the audio data of the disc number 150 and the song number 3 in the stocker 1 is output to T1, and the image data of the disc number 20 and the image number 5 in the stocker 2 is output to T2, respectively. Provided to the person.

Subtitle data such as lyrics used in a normal karaoke device is recorded in the subcode area on the CD side or in the CD.
-It can be recorded on either side of the ROM.
When recorded in the subcode area of a CD, a video is created from the subtitle data in the subcode at the same time when the audio information is reproduced, and superimposed. When recorded on the CD-ROM side, the subtitle data is read from the disc number and the song number and stored in the memory prior to the reproduction, and then the audio information and the image information are reproduced. At the same time, a video may be created from the subtitle data and superimposed.

In the above description, a plurality of CDs, CDs
-A predetermined CD or a predetermined CD-ROM in which the genre codes of all the songs contained in the ROM are recorded
Was described as the disk number n or the disk number m, but the present invention is not limited to this, and any specific disk number k,
It may be recorded on a CD or a CD-ROM. This disk number may be designated at the time of installation, or this disk number may be registered in the device in advance.

In the above-mentioned embodiment, the genre code of voice is described as an example recorded in the sub-code, but instead of the sub-code, a part of the CD is converted into a CD-ROM and recorded therein. Good.

Further, in the present invention, since the genre code is read out only by reproducing one recording medium such as a CD and a CD-ROM, a volatile memory device is used instead of the non-volatile memory device 6. The genre code may be read when the power is turned on. In this case, although it takes some time to start up, the cost of the device can be reduced.

The present invention is not limited to CDs and CD-ROMs,
