[0016]
Next, the operation of the above-described 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 disk on the turntable of the player unit 4. A disc set command is issued to the disc transport unit 3 (step S2). 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 S3), the system controller 7 instructs the player unit 4 to rotate the disk (step S4), and instructs the player unit 4 to read data (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 the non-real-time file area of the disk.
[0017]
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), and determines whether or not the reading of the data by the player unit 4 has been completed (step S7). For example, the data supplied by executing step S6 is written to the RAM 13 until a bit indicating the end of the data supply is supplied and it is known that the data reading has been completed. 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 drive of the turntable, and thereafter, the disk transport unit 3 transports the disk on the turntable to a predetermined storage position of the disk in the disk storage unit 2 and stores it. After executing step S9, the system controller 7 determines 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.
[0018]
The data to be written in the RAM 13 may be all of the data of the access information file and the karaoke information file described above, but at least a disk number unique to the disk, an address indicating the storage position of the disk storage unit 2 of the disk, a song name, a singer name, a lyric The song data may include only the name of the player, the name of the composer, the length of the song, the copyright code, the genre of the song, the tempo of the song, the difficulty level of the song, and the multi-audio mode.
[0019]
The storage of a new disk can be obtained by 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. May be compared with each other to determine the storage of a new disk and to write the detection result into the RAM 13.
[0020]
Further, in the above-described embodiment, the song data such as the song title is obtained at the time of installation of the disc in which the song data is recorded together with the image data and the audio data. Sometimes song data may be obtained. 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 at the time of installing the one disc. May be.
[0021]
After the installation operation is performed as described above, karaoke reproduction of the song 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 S11). Then, 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 performance, and when the performance is completed, the order is advanced. The music name 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 S14). 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 instead 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 as a character image on the display 22 and that the selection of the song operated by the key is performed.
[0022]
After executing step S14, the system controller 7 reads out the copyright code corresponding to the read music selection number from the RAM 13 (step S15). Since the RAM 13 has a copyright code in the data read and written from the disk at the time of the installation operation, the copyright code is read. The copyright code is a code indicating the copyright owner of the music. It is determined whether or not the selected music piece is a recordable music piece 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 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. When displaying on the display 22, display character data indicating that recording is possible or not is generated in the display character control circuit 20 in response to a command from the system controller 7, and is written to the V-RAM.
[0023]
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 indicates recording corresponding to the music selection number. " 1 ".
[0024]
Next, the disk playing operation will be described. As shown in FIG. 8, when the system controller 7 first instructs the start of the performance 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 performance 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), it instructs the player unit 4 to rotate the disk (step S26), and determines whether or not the disk playing can be started (step S26). S27). For example, when the performance is prohibited by the key operation of the operation unit 15, the disk performance is not started. If the disc performance can be started, a disc performance from the track of the read music number is instructed (step S28). Therefore, the player section 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.
[0025]
Also, 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.
[0026]
After execution of step S30, the system controller 7 reads from the RAM 13 the recorded music information corresponding to the music selection number read in step S22 (step S31). The recorded music information is at least the name of the music, the name of the lyricist, and the name of the composer, 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). The printer 17 prints the recorded music information on a label attached to the 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.
[0027]
After execution of step S32, the system controller 7 determines whether or not the performance 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 according to the performance of the disk. When the performance of the selected music has been completed, a performance stop command is issued to the player section 4 (step S34), and a disc return command is issued to the disc transport section 3 (step S35). Therefore, the player unit 4 stops the disk playing operation, and the disk transport unit 3 transports the disk on the turntable to the predetermined storage position of the disk in the disk storage unit 2 after the rotation of the turntable stops. To store. After the disk return command is issued, the system controller 7 advances the music order of the music selection list table by one music (step S36), and determines whether or not the music selection number is recorded first in the music 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 the music selection number has not been recorded, the performance operation ends.
[0028]
FIG. 9 shows another procedure of the installation operation. This installation operation is for a disk in which the copyright owner and the recording permission / non-permission information and the recording permission / prohibition information registration date are recorded in addition to the copyright code. The table is formed in the RAM 13 instead of the ROM 14. That is, as shown in FIG. 9, steps S1 to S7 are the same as the installation operation shown in FIG. 4, and the read data is written to the RAM 13 via the system controller 7. In this writing operation, the copyright holder and the recording permission / inhibition data are not written in the recording permission / inhibition data table, but are simply written as data for each disk or music. When the data reading is completed, it is determined whether or not the recording permission / prohibition information registration date read from the disk is the latest (step S41). If the recording date is not the newest registration date stored in the RAM 13, the process proceeds to step S8 to stop the operation of the player unit 4. On the other hand, if the recording permission information is a newer registration date than the latest registration date, the recording permission / inhibition data table is updated with the read copyright owner and the recording permission / inhibition information (step S42). The information is updated according to the information registration date (step S43). After performing step S43, the process proceeds to step S8. Steps S8 to S10 are the same as the installation operation shown in FIG.
[0029]
It should be noted that the serviceman for maintenance and inspection of the karaoke reproducing apparatus may be able to change the copyright holder and the recording permission / prohibition data in the recording permission / prohibition data table by operating a special key on the operation unit 15. It is apparent that the recording medium on which at least a plurality of karaoke performance sounds are recorded is not limited to a disk but may be another recording medium such as a tape.
