Next, the operation of the above karaoke player will be described.
[0020]
When a disk is newly stored in the disk storage unit 2 of the autochanger 1, first, an installation operation is 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), so that the disk is mounted on the turntable of the player unit 4. A disk set command is issued to the disk transport unit 3 (step S2). When the disc transport unit 3 finishes mounting the disc 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), it instructs the player section 4 to drive the disk to rotate (step S4), and instructs the 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 the non-real-time file area of the disk.
[0021]
The read data is supplied to the system controller 7 via the data separation circuit 6 and temporarily stored in a buffer memory (not shown) in the system controller 7. The system controller 7 sequentially writes the supplied data to the external RAM 13 (step S6), and determines whether or not the data reading by the player unit 4 has been completed (step S7). For example, the data supplied by the execution of step S6 is written into the RAM 13 until it is determined that the data reading has been completed by supplying a bit indicating the end of the data supply. 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 rotational drive of the turntable, and then the disc transport unit 3 transports and stores the disc on the turntable to a predetermined storage position of the disc in the disc storage unit 2. After executing step S9, the system controller 7 determines whether 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 no other new disk is stored, the installation operation is terminated.
[0022]
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 the disk number unique to the disk, the address indicating the storage position of the disk storage part 2 of the disk, the song name, the singer name, the lyrics Only the song data such as the name, composer name, song length, copyright code, song genre, song tempo, song difficulty, and multi-audio mode may be used.
[0023]
The storage of a new disk can be obtained by an input from the operation unit 15 by the user. In addition, 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 discriminating whether a new disk is stored, and writing the detection result in the RAM 13.
[0024]
Further, in the above embodiment, the song data such as the song name is obtained at the time of installation of the disc recorded together with the image data and the audio data, but the disc installation is performed from the dedicated disc on which only the song data such as the song name is recorded. Sometimes you may get song data. Alternatively, the song data of a plurality of discs on which image data and audio data are recorded are recorded on one of the plurality of discs, and these song data are obtained when the one disc is installed. May be.
[0025]
After the installation operation is performed as described above, karaoke playback can be performed for the song selected by the user. First, in the music selection operation, the user inputs the 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 that designates a disc and a song recorded in 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 has been operated at a predetermined timing or in an interrupt operation (step S11). Then, the music selection number is read from the buffer and written in 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 to be described later are written in the order of performance, and the order is advanced when the performance is completed. The music name corresponding to the read music selection number is read from the RAM 13 as information data (step S13), and the read data is supplied to the 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 in a predetermined position of the V-RAM. Display character data is read from the V-RAM and converted into a character video signal, which is then output to the image synthesizer 21. The character video signal is synthesized in the video synthesizer 21 by being output in place of the video video signal from the D / A converter 12 when the video synthesizer 21 is a signal indicating a predetermined color. Therefore, the music title is displayed on the display 22 as a character image, and it is confirmed that the key selection operation has been accepted.
[0026]
After executing step S14, the system controller 7 reads the copyright code corresponding to the read music selection number from the RAM 13 (step S15). Since there is a copyright code in the data read from the disk and written in the RAM 13 during the installation operation, it is read out. The copyright code is a code indicating the copyright owner of the song. 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, as shown in FIG. 7, a copyright code, a copyright holder, and recording availability are written in advance as a recording availability data table. As for recording availability, “1” can be recorded, and “0” cannot be recorded. Therefore, it is determined from the recording availability data table whether or not the selected song is a recordable song. If recording is possible, a recordable display is made (step S17), and if recording is impossible, a record impossible display is made (step S18). These displays may be displayed on the display 22 or a display (not shown) for recording availability provided in the apparatus. 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 impossible to record, and writes it in the V-RAM in response to a command from the system controller 7.
[0027]
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 in the music selection list table is set (step S20). Since “0” indicating non-recording is previously written as the initial value of the recording flag in the music selection list table, when the recording reservation key is operated, the recording flag is set to indicate recording corresponding to the music selection number. 1 ”.
[0028]
Next, the disc performance operation will be described. As shown in FIG. 8, when the system controller 7 is first instructed to start performance by operating the key of the operation unit 15 (step S21), the music selection number and the music selection number from the first in the music selection list table formed in the RAM 13 are displayed. The recording flag is read (step S22). A disk address and a 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 so that the disk of the read disk address is mounted on the turntable of the player unit 4. (Step S24). When the disc transport unit 3 finishes mounting the disc 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 drive the disk to rotate (step S26), and determines whether or not the disk performance can be started (step S26). S27). For example, when the performance is prohibited by the key operation of the operation unit 15, the disc performance is not started. If the disk performance can be started, the disk performance is instructed from the track of the read music number (step S28). Therefore, the player unit 4 starts playing the music designated by the music selection number, and the reproduced video signal and audio signal are output to the display 22 and the speaker 19.
[0029]
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, recording onto the compact disc is performed in response to the recording start command.
[0030]
After executing step S30, the system controller 7 reads the recorded music information corresponding to the music selection number read in step S22 from the RAM 13 (step S31). The recorded song information is at least a song name, a songwriter name, and a composer name, and information such as a singer, recording date and time, and location may be added. After reading the recorded music piece information, it is output to the printer 17 (step S32). The printer 17 prints the recorded song information on a label that is attached to the compact disc. Thus, if the label is affixed 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.
[0031]
After executing step S32, the system controller 7 determines whether or not the performance of the selected song has been completed (step S33). This is determined from the time information in the control data supplied from the data separation circuit 6 by the disc performance. When the performance of the selected song is completed, a performance stop command is issued to the player unit 4 (step S34), and a disc return command is issued to the disc transport unit 3 (step S35). Therefore, the player unit 4 stops the disc playing operation, and the disc transport unit 3 transports the disc on the turntable to the predetermined storage position of the disc in the disc storage unit 2 after the turntable stops rotating. Store. After the disc return command is generated, the system controller 7 moves up the music order in 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 is recorded, the process returns to step S22 and the above operation is repeated. On the other hand, if the music selection number is not recorded, the performance operation is terminated.
[0032]
FIG. 9 shows another procedure of the installation operation. In this installation operation, in addition to the copyright code, in addition to the copyright code, the recording of the copyright holder, recording availability, and information on the recording availability information registration date, the recording availability data shown in FIG. A table is formed in the RAM 13 instead of the ROM 14. That is, as shown in FIG. 9, steps S <b> 1 to S <b> 7 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 availability data are not written in the recording availability data table, but are simply written as data for each disc or song. When the data reading is completed, it is determined whether or not the recording availability information registration date read from the disc is the latest (step S41). If it is not a recording availability information registration date that is newer than the latest registration date stored in the RAM 13, the operation proceeds to step S8 to stop the operation of the player unit 4. On the other hand, if the recording availability information registration date is newer than the latest registration date, the recording availability data table is updated with the read copyright owner and recording availability information (step S42), and the recording availability is read from the latest registration date. It is updated according to the information registration date (step S43). After execution of step S43, the process proceeds to step S8. Steps S8 to S10 are the same as the installation operation shown in FIG.
[0033]
It should be noted that a service person such as a maintenance / inspection of the karaoke player may be able to change the copyright holder and the recording availability data in the recording availability data table by operating a special key of the operation unit 15.
[0034]
Further, it is obvious that the recording medium on which at least the karaoke performance sounds of a plurality of songs are recorded is not limited to the disk, but may be another recording medium such as a tape.
[0035]
