Next, the operation of the above karaoke reproducing apparatus will be described. When a disk is newly stored in the disk storage section 2 of the autochanger 1, an installation operation is first performed. In this installation operation, the system controller 7 detects that a new disk is stored in the disk storage unit 2 as shown in FIG. 4 (step S1), and mounts the new disk on the turntable of the player unit 4. Disk transport unit 3
Issue a disk set command (step S
2). When the disk transport unit 3 finishes mounting the disk on the turntable of the player unit 4, it is supplied to the system controller 7 as a mounting end signal. Therefore,
Upon receiving the mounting end signal (step S3), the system controller 7 instructs the player unit 4 to rotate the disk (step S4), and instructs data reading (step S5). The player unit 4 rotates the disk together with the turntable, and after the rotation reaches a predetermined rotation speed, reads and outputs data from a non-real-time file area of the disk.

The read data is supplied to the system controller 7 via the data separation circuit 6, and is temporarily stored in a buffer memory (not shown) in the system controller 7. The system controller 7 sequentially writes the supplied data into the external RAM 13 (step S6),
It is determined whether or not the reading of data by the player unit 4 has been completed (step S7). For example, until the bit indicating the end of the data supply is supplied and it is determined that the data reading is completed, the supplied data is written in the RAM 13 by the execution of the step S6 to form a data table. When the data reading is completed, an operation stop command is issued to the player unit 4 (step S8), and a disc return command is issued to the disc transport unit 3 (step S9). Therefore, the player unit 4 stops the rotation of the turntable, and thereafter, the disk transport unit 3 transports and stores the disk on the turntable to a predetermined storage position of the disk in the disk storage unit 2. The system controller 7 performs step S
After execution of step 9, it is determined whether or not another new disk has been stored (step S10). If another new disk is stored in the disk storage unit 2, the process proceeds to step S2, and if there is no other new disk stored, the installation operation ends.

The data to be written into the RAM 13 may be all data of the above-mentioned access information file and karaoke information file, but at least a disk number unique to the disk and a disk storage unit 2 of the disk corresponding to the music code of each music. Address indicating the storage location, the location of the song on the disc, song name, singer name, lyricist name, composer name, song length, copyright code, song genre, song theme image and song theme, song title Only song data such as situations and special genres of songs may be used.

The storage of a new disk can be obtained by an input from the operation unit 15 by the user. Further, a sensor for detecting the presence or absence of a disk is provided at each storage position of the disk storage unit 2, and an area for storing the detection result is provided in the RAM 13. And compare
The storage of a new disk may be determined, and the detection result may be written to the RAM 13.

Further, in the above-described embodiment, the music data such as the music title is obtained at the time of installing the disc in which the music data is recorded together with the image data and the audio data. The song data may be obtained when the disc is installed. Alternatively, music data of a plurality of discs on which image data and audio data are recorded is recorded on one of the plurality of discs, and the music data is obtained when the one disc is installed. May be.

After the installation operation is performed as described above, karaoke reproduction of the music selected by the user can be performed. First, in the music selection operation, the user inputs a music selection number by operating the numeric keys or alphabet keys of the operation unit 15 or the remote control transmitter 23. The music selection number is composed of a plurality of digits and is a number for designating a disc and music recorded on the disc. When a key is operated, the music selection number is held in a buffer (not shown) in the operation unit 15. As shown in FIG. 5, the system controller 7 determines whether or not a music selection key (not shown) of the operation unit 15 is operated at a predetermined timing or by an interrupt operation (step S).
11) If the music selection key is operated, the music selection number is read from the buffer and written into the music selection list table of the RAM 13 (step S12). The music selection list table is formed in the RAM 13 and, as shown in FIG. 6, a music selection number and a recording flag described later are written in the order of reproduction, and when the reproduction is completed, the order is advanced. The music title corresponding to the read music selection number is read from RAM 13 as information data (step S13), and the read data is supplied to display character control circuit 20 (step S1).
4). In the display character control circuit 20, display character data indicating a song title is generated and written to a predetermined position in the V-RAM. The display character data is read from the V-RAM and converted into a character video signal, and then output to the image synthesizer 21. When the character image signal is a signal indicating a predetermined color in the image synthesizer 21, the character image signal is output in place of the moving image signal from the D / A converter 12 to be synthesized with the moving image signal. Therefore, it is confirmed that the song title is displayed on the display 22 as a character image and that the selection of the song operated by the key has been accepted.

The system controller 7 proceeds to step S14.
, The copyright code corresponding to the read music selection number is read from the RAM 13 (step S15). RAM
13 has a copyright code in the data read and written from the disk at the time of the installation operation, so that it is read. The copyright code is a code indicating the copyright owner of the music. It is determined whether or not the selected song is a recordable song based on the read copyright code (step S16). In a ROM (read only memory) 14 provided outside the system controller 7, a copyright code, a copyright holder, and a recording permission / prohibition data table are previously written as a recording permission / prohibition data table as shown in FIG. Regarding whether or not recording is possible, "1" indicates that recording is possible and "0" indicates that recording is not possible.
Therefore, it is determined from the recordability data table whether or not the selected song is a recordable song. If recording is possible, a recording possible display is made (step S17), and if recording is impossible, a recording impossible display is made (step S18). These displays may be displayed on the display 22 or may be provided on a display (not shown) for determining whether or not recording is possible. In the case of displaying on the display 22, the display character control circuit 20 generates display character data indicating that recording is possible or not in response to a command from the system controller 7, and the V-
Written to RAM.

The system controller 7 determines whether or not there is a recording reservation after executing step S17 because recording is possible (step S19). This is determined by whether or not the recording reservation key of the operation unit 15 or the remote control transmitter 23 has been operated. If there is a recording reservation, the recording flag of the above-mentioned music selection list table is set (step S20). Since “0” indicating non-recording is previously written in the music selection list table as an initial value of the recording flag, when the recording reservation key is operated, the recording flag is set to indicate recording according to the music selection number. 1 ".

Next, the disc reproducing operation will be described. As shown in FIG. 8, when the system controller 7 first instructs the start of reproduction by operating the keys of the operation unit 15 (step S21), the music selection number and the music selection number from the first in the reproduction order of the music selection list table formed in the RAM 13 are displayed. The recording flag is read (step S22). The disk address and music number corresponding to the read music selection number are read from the RAM 13 (step S23), and a disk set command is issued to the disk transport unit 3 to mount the disk with the read disk address on the turntable of the player unit 4. (Step S24). When the disk transport unit 3 finishes mounting the disk on the turntable of the player unit 4, it is supplied to the system controller 7 as a mounting end signal. Therefore, when the system controller 7 obtains the mounting end signal (step S25), the player unit 4
Is instructed to rotate the disk (step S2).
6) It is determined whether or not the disk reproduction can be started (step S27). For example, when the reproduction is prohibited by the key operation of the operation unit 15, the disk reproduction is not started. If the reproduction of the disk can be started, the reproduction of the disk from the track of the read music number is instructed (step S28). Therefore, the player unit 4 starts playing the music specified by the music selection number, and the reproduced video signal and audio signal are output to the display 22 and the speaker 19.

Further, it is determined from the read recording flag whether or not recording is reserved (step S29). If the recording flag is set to "1", a recording start command is issued to the recording device 16 (step S30).
Since the audio signal including the singing sound is supplied from the amplifier 18 to the recording device 16, the recording on the compact disc is performed according to the recording start command.

The system controller 7 proceeds to step S30.
, The recorded music information corresponding to the music selection number read in step S22 is read from the RAM 13 (step S22).
31). The recorded song information is at least a song name, a lyricist name, and a composer name, and information such as the singer, the recording date and time, and the location may be added. After reading these pieces of recorded music information, they are output to the printer 17 (step S32). Printer 17
Prints the recorded song information on a label that is attached to a compact disc. Thus, if the label is attached to the label surface of the recorded compact disc, the recorded music is recorded. Of course, the recorded music information may be printed directly on the label surface of the compact disc instead of the label.

The system controller 7 proceeds to step S32.
After the execution of, it is determined whether or not the reproduction of the selected music has ended (step S33). This is determined from the time information in the control data supplied from the data separation circuit 6 by reproducing the disk. When the reproduction of the selected music is completed, a reproduction stop command is issued to the player unit 4 (step S3).
4) A disc return command is issued to the disc transport unit 3 (step S35). Therefore, the player unit 4 stops the disc reproducing operation, and the disc transport unit 3 conveys the disc on the turntable to the predetermined storage position of the disc in the disc storage unit 2 after the rotation of the turntable is stopped. To store. System controller 7
After the disc return command is issued, the song order in the song selection list table is advanced by one song (step S36), and it is determined whether or not the song selection number is recorded first in the song selection list table (step S37). If the music selection number has been recorded, the process returns to step S22 and the above operation is repeated. On the other hand, if no music selection number has been recorded, the reproduction operation ends.

If the user does not know the name of the song he or she wants to sing, or if he wants to sing a song that suits his mood or atmosphere at that time, the user operates the search key (not shown) of the operation unit 15 instead of the song selection operation. Will be. When the search key is operated, the system controller 7 starts a music title search operation. In the song name search operation, as shown in FIGS. 9 to 11, the system controller 7 first instructs the display character control circuit 20 to display the category item table of the song category information used for the search (step S41). In this example, the classification items of the music classification information are the theme image and music theme of the music included in the common information in the chapter, the situation of the music, and the special genre of the music. A display command is issued by supplying a list of these classification items to the display character control circuit 20 as data. This list data can be provided in a program for a song name search operation. In the display character control circuit 20, display character data indicating the classification item table is generated and written to a predetermined position in the V-RAM. After the display character data is read from the V-RAM and converted into a character image signal, the image synthesizer 2
1 to the display 22. Therefore, on the screen of the display 22, the classification items of the music classification information are displayed as character images, for example, as shown in FIG. It should be noted that the image synthesizer 21 can switch between a display in which images are combined and a display in which only characters are displayed, and may display only characters in a search operation.

Here, the song classification information includes information depending on the content of the lyrics of the song, such as information common in the chapter, as well as the nationality and age of the song, whether or not it can be recorded, whether or not duet is possible, and external devices such as lighting. The information is composed of a wide range of items such as whether or not automatic control is possible, and none of the items is language-dependent, and the song can be applied to any of a plurality of options existing in the item. Therefore, a predetermined number of bits is assigned to each item, and the options in the item are encoded with the number of bits, and each song is assigned the code of the applied option. As described above, the song classification information is different from the singer name, lyricist name, and composer name described in characters depending on the language.

The system controller 7 determines whether there is a selection input from the operation unit 15 (step S4).
2). The selection input is performed by a numeric key. When the key is operated, the selection number, which is one-byte data, is held in the buffer in the operation unit 15. If there is a newly held selection number in the buffer, the system controller 7 reads the selection number (step S4).
3) It is determined whether or not the reading selection number is No. 1, that is, whether or not it indicates the theme image and the song theme of the song (step S4).
4). If the read selection number does not indicate No. 1, it is determined whether the read selection number is No. 2, that is, a selection number indicating the situation of the music (step S45). If the read selection number does not indicate No. 2, it is determined whether or not the read selection number is No. 3, that is, a selection number indicating a special genre of the music (step S46).

If it is determined in step S44 that the theme image of the song and the selection number indicating the song theme have been read, the display of the song theme image selection table is instructed to the display character control circuit 20 (step S47). The theme image of the song is love, life, and other three as shown in FIG.
Consists of two options. A display command is issued by supplying a list of these options to the display character control circuit 20 as data. By the same operation as the display of the classification item table of the music classification information described above, the theme image selection table of the music is displayed on the display 22 as a character image.

After instructing the display of the theme image selection table of the music, the system controller 7 determines whether or not there is a selection input from the operation unit 15 (step S48). When a key is operated, a selection number, which is 1-byte data, is held in a buffer in the operation unit 15. If there is a newly held selection number in the buffer in the operation unit 15, the system controller 7 reads the selection number as the theme image A of the music (step S49). Then, the theme image A of the song
Display of the song theme selection table according to the display character control circuit 20
(Step S50). As a result, the first song theme selection table is displayed on the display 22 if the theme image A of the song is a code indicating love, the second song theme selection table is displayed if the song is a life, and the second song theme selection table is displayed otherwise. A three song theme selection table is displayed. FIG. 14 shows the contents of each song theme, that is, options.

After instructing the display of the music theme selection table, the system controller 7 determines whether or not there is a selection input from the operation unit 15 (step S51). This selection input is similarly performed by a numeric key, and when a key is operated, the selection number is held in a buffer in the operation unit 15. If there is a newly held selection number in the buffer, the system controller 7 reads the selection number as the music theme B (step S52). Thus, two-byte data AB corresponding to the theme image of the song and the contents of the song theme are obtained.

If it is determined in step S45 that the selection number indicating the song situation has been read,
The display of the music situation selection table is instructed to the display character control circuit 20 (step S53). The situation of the song is Christmas, birthday,
It consists of options such as Valentine's Day. A display command is issued by supplying a list of these options to the display character control circuit 20 as data. As a result, the song situation selection table is displayed on the display 22 as a character image. After instructing the display of the song situation selection table, the system controller 7 determines whether or not there has been a selection input from the operation unit 15 (step S54). If there is a newly held selection number in the buffer in the operation unit 15, the system controller 7 reads the selection number as the situation C of the music (step S5).
5).

If it is determined in step S46 that the selection number indicating the special genre of the music has been read, the display of the special genre selection table of the music is instructed to the display character control circuit 20 (step S56). As shown in FIG. 16, the special genre of the song includes options such as a CM song, a TV drama theme song, and other theme songs. A display command is issued by supplying a list of these options as data to the display character control circuit 20, and a special genre selection table of the music is displayed on the display 22 as a character image. After instructing the display of the special genre selection table of the music, the system controller 7 determines whether or not there is a selection input from the operation unit 15 (step S57). If there is a newly held selection number in the buffer in the operation unit 15, the system controller 7 sets the selection number to the special genre D of the song.
(Step S58).

The system controller 7 determines in step S5
2. After execution of any one of steps S55 and S58,
The display of the character "Do you want to select a classification item of other music classification information?" Is instructed to the display character control circuit 20 (step S59). According to this command, the above-mentioned characters are displayed on the display 22. Therefore, the user can operate the keys of the operation unit 15, for example, Y (yes) or N
(No) will respond. Therefore, the system controller 7 determines whether or not there has been an input from the operation unit 15 (step S60). If there is an input from the operation unit 15, it is determined whether or not the input is affirmative (step S61). If the input from the operation unit 15 is positive, the process returns to step S41, and the above operation is repeated. On the other hand, when the input is negative, the process proceeds to the next step S62. It should be noted that the numbers A to D corresponding to the classification items of the music classification information that are not selected indicate the initial values 0 as they are.

In step S62, the system controller 7 searches the RAM 13 for a song corresponding to the theme image A and the song B of the song, the situation C of the song, and the special genre D of the song. That is, the theme image of the music, the theme of the music, the situation of the music, and the special genre of the music are coded and written in the RAM 13 for each music by the installation operation. And a song whose theme is equal to A and B, the situation of the song is equal to C, and the special genre of the song is equal to D.
It is stored in a memory (not shown). However,
The classification item whose selection number is 0 is ignored. When the search in step S62 is completed, it is determined whether or not the corresponding song exists (step S63). As a result of the search,
If no music code is stored in the system controller 7, the display of the character "No corresponding music" is instructed to the display character control circuit 20 (step S6).
4). On the other hand, if the music code is 1 in the system controller 7,
If at least one is stored, the song names corresponding to all the stored song codes, that is, the song names of the corresponding songs, are stored in RAM.
13 (step S65), and supplies the read song name and the song code to the display character control circuit 20 as paired data (step S66). Therefore,
In the display character control circuit 20, display character data indicating a music code and a music title is generated and written in a predetermined position in the V-RAM, and the display character data is read out from the V-RAM and converted into a character video signal. Thereafter, it is supplied to the display 22 via the image synthesizer 21 and
Displays at least one song code obtained by the search and the song title as a character image. The display of each table for the search and the display of the music code and the music title of the search result may be performed on a display different from the display 22.

When the user operates the music selection key (not shown) of the operation unit 15 after the music name search operation is completed, the system controller 7 starts the music selection operation in the same manner as the above operation. The user selects a desired song from the song titles displayed on the display 22 with the song code as the song selection number. Alternatively, a number may be assigned to each search tune at the time of display, and selection may be made using that number.

In the above-described song title search operation, the user finally selects a desired song from the song titles displayed on the display 22, but the karaoke reproducing apparatus may automatically select songs. In this case, as shown in FIG. 17, if it is determined in step S63 that the corresponding music piece exists and at least one music piece code is stored in the memory of the system controller 7, the system controller 7
Randomly selects one music code from all the music codes stored in the internal memory (step S71), and writes the music code as a music selection number in the music selection list table of the RAM 13 (step S72). Thereafter, the process forcibly shifts to step S13 of the above-mentioned music selection operation, reads the music name corresponding to the music selection number as information data from the RAM 13, and supplies the read data to the display character control circuit 20 in step S14. Therefore, the name of the song as a result of the automatic song selection is displayed on the display 22, and the song to be sung can be confirmed by the user.

As another method for performing a search using a combination of a plurality of items shown in the above-described embodiment, a plurality of items in which the contents selected from the respective options of the plurality of items are prepared in advance are prepared, and There is a way to select a set. For example, as shown in FIG. 18, a combination of frequently selected contents is displayed as a set, and the selector selects by number. In this case, the search for the corresponding music can be performed with a small number of operation procedures.

Further, as still another method for searching by a combination of a plurality of items, an option with a classification different from the information related to the song recorded in the karaoke information file is presented, and the selected content is associated with the song. There is a search method corresponding to the information to be performed. For example, when an option as shown in FIG. 19 is presented, and “before the percussion song before the 70's” is selected, the system controller 7 selects “(2) year of release of the song” in the common information in the chapter among the information related to the song. time"
And the theme image of the song and the “confession (male → female)” of “love” in the theme are searched for the corresponding song. In this way, by directly setting the content of the music singer's request as a choice, it is possible to more easily search for a tune that meets the request.

If the common information in the chapter "(15) Control device information" is used, a search by function can be performed. FIG. 20 shows an example of “(15) Control device information”. One bit corresponds to one external device.
When the value of a bit is “1”, it indicates that an external device corresponding to the bit can be controlled. Therefore, if a search is made on the condition that the music can be controlled, for example, the system controller 7 searches for the music whose bit 15 is “1” and displays it on the display 22 via the display character control circuit 20. In this way, the music selector can select a desired music piece from among music pieces that can achieve the desired function.

In the above example, the common information in the chapter is used as the information used for the search. However, bibliographic information such as a singer name, a lyricist name, and a composer name is used alone or in combination with the common information in the chapter. May be used for searching. By using the common information "(4) copyright code" in the chapter, it is possible to search for a song under the condition that recording is possible, and it is possible to easily answer a user's request to sing a song that can be recorded.

"(5) Singer classification" of the common information in the chapter
Is used, a song can be searched under the condition of a song to be sung in a duet, and a user who wants to sing in a duet can easily select a desired song from the songs in the duet. By referring to the “multi-audio mode (13)” of the common information in the chapter, when the song has audio of four channels, the contents of two channels of the sub audio can be known. Search by contents. For example, in the case where (Karaoke accompaniment) + (one vocal of a duet) is recorded on one channel of the sub-audio and (Karaoke accompaniment) + (the other vocal of the duet) is recorded on the other channel, the user may select one of the following. By selecting playback of one of the channels, duet can be performed between the recorded vocals and the user. If “(13) Multi audio mode” is used as a classification item, it is possible that a song can be duet by one person. You can easily search.

In the present invention, it is apparent that the recording medium on which at least music information of a plurality of music pieces is recorded is not limited to a disk, but may be another recording medium such as a tape.
