Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc-shaped recording medium and a player system, and more specifically to a CD-I (CD
Interactive) and a player system which carries out a reproducing operation corresponding to this.

[0002]

2. Description of the Related Art A CD-I capable of recording audio information, image information, various data, characters, etc. is known as one of optical disc recording media. Various devices and media for education and business have been realized. For example, one of them is CD-
It is often the case that music (and video) information is recorded in I and this is used as software in a karaoke device or a music player device.

[0003]

By the way, CD-I
For example, when used for music use, the recorded data is not only the music signal of each music (and the video signal may be added correspondingly), but also a control program for playing the music. Will also be recorded. This control program is for selecting various music numbers to be played and for controlling various operations such as execution, interruption, and end of performance of the selected music.

In a player equipped with an optical pickup device, an audio signal processing section, a speaker and the like corresponding to such a music CD-I, the CD-I is first loaded when the CD-I is loaded. The control program recorded in I is read and held in the RAM, and thereafter, the reproduction drive is performed based on the control program held in the RAM.

That is, on the player side, each mechanism / device in the player device is simply used for the loading operation of the CD-I, the drive control of the optical pickup, or the processing of the audio signal and the video signal reproduced from the CD-I. Only the operation control program for the circuit section is provided in the ROM, and the program for controlling which music and how to perform the music (video) actually recorded on the CD-I is held. Absent.

Therefore, even if the user wants to select a song, interrupt a song, or perform special reproduction, it is not possible to provide the player with an operation panel for user operation. That is, the RAM is independently provided without a control program and communication means for each mechanism of the player.
This is because operation information cannot be input to the control program stored in.

Therefore, since the control program usually includes a list display program and a mouse management program, if the user wants to select a song, interrupt a song, or perform special reproduction, the song list is displayed on the video monitor, for example. A method of executing display and operation input display and directly input operation information to a control program held in the RAM by using a mouse. However, in this case, the operability is not good, and there is a problem that it is very inconvenient especially for a person who is not accustomed to operating a mouse, and a situation in which the user cannot use the mouse as intended tends to occur.

Steps in the flowchart of FIG.
F101 to F109 indicate the control operation by the operation key management program, and steps F201 to F207 are the control program 1
2 shows the control operation according to 2. In addition, ~ indicates a communication operation between the operation key management program and the control program 12. It should be noted that this flowchart shows the control after the user selects the music number to be played by the panel operation unit 30 and operates so as to enter the play state. For the purpose of explanation, the operations that the user can perform are the operation of selecting the song number to be played and the operation of canceling the song being played.

When the user specifies a certain music number by the panel operation unit 30, this information is held by the operation key management program (F101, F102), but the control program 12 determines what the selected music number is. Outputs a song number request signal to ask the operation key management program (F201, communication). When the operation key management program receives this music number request signal, it outputs to the control program 12 a signal indicating the music number held based on the user's operation on the panel operation unit 30 (F104,
F105, Communications).

Note that the music program number request signal by the control program 12 may be repeatedly performed at predetermined time intervals. Therefore, in this case, the operation key management program is operated after the time when the operation information by the panel operation unit 30 is held. It corresponds to the first music number request signal.

When the control program 12 receives the tune number (F202), the tune corresponding to this tune number is the C
Control program 1 whether or not it is in D-I10
2 is checked, and if it exists, a control signal is issued to the CD driver controller 23 to access the music data and the video data at the song number. And
A reproduction operation of the accessed music data and video data is executed, an audio signal and a video signal are reproduced, and audio and video output are performed from the speaker 27 and the monitor 25 (F203).

When the performance of the music is completed, the control program 12 outputs a music end notification to the operation key management program (F204 → F206, communication). The operation key management program that has received the song end notification executes the required processing according to the content of the notification, and then outputs a song end confirmation notification to the control program 12 (F106,
F107, communication). When the control program 12 receives the music end confirmation notification, it returns to step F201 and requests the next music number (communication). That is, it waits while outputting the music piece number request signal every predetermined time.

When the operation of stopping the performance of a music piece is performed by the panel operation unit 30, first, the operation key management program determines whether or not a certain music piece is currently playing, for example, whether or not a music piece end notification has already been given. Etc. (F103 →
F108), if it is playing, a stop request signal is output to the control program 12 (F109, communication). Upon receiving the stop request signal, the control program 12 immediately stops the reproduction operation of the music and outputs the music end notification as at the end (F205, F206, communication). In response to this, the operation key management program outputs a song end confirmation notification (F
106, F107, communication), the control program 12 returns to step F201 and enters a standby state for panel operation.

By the control operation including communication by the operation key management program and the control program 12 described above, the operation panel 30 on the player system 20 side
It is possible for the user to very easily execute selection of a music piece and suspension of music performance, and the operability can be remarkably improved as compared with inputting operation information to the control program 12 by a mouse. Therefore, it is suitable for use in, for example, a karaoke device.

It should be noted that it is conceivable that a user operation such as a special reproduction can be performed in addition to the cancel operation, but these may be processed in an interrupting manner in substantially the same manner as the cancel operation in the above flowchart. .. Further, although the panel operation unit 30 is provided for the user operation on the player system side, the user operation means may be realized by another configuration such as an infrared light receiving unit and an infrared remote commander. Further, the control operations of the operation key management program and the control program are not limited to those shown in FIG. 3, and should be variously changed according to the actual system.

[0029]

As described above, in the disc-shaped recording medium of the present invention, the control program recorded for controlling the reproduction operation has a control information communication function with the operation input management program in the player system. In addition, the player system of the present invention has operation input means for reproducing the disc-shaped recording medium, and an operation input management program for managing operation information input by the operation input means. Since the control program of the disc-shaped recording medium and the operation input management program are configured to communicate required control information, which data and how in the CD-I is handled by the user operating means on the player system side. The operation for designating whether to play or not can be performed very easily. Operability to, there is an effect that it is possible to significantly improve the usability.
