The present invention relates to a power supply device for a compact disc-interactive (CD-1) player. In particular, in order to reduce power consumption, a power supply for a full motion video (FMV) unit according to the type of a compact disc (CD) is provided. It relates to a compact disk interactive power supply for turning on / off.

FIG. 1 is a block diagram schematically showing the structure of a conventional CD-1 player, and includes a base case 10, an FMV unit 20, and a power supply 30. As shown in FIG. That is, in general, when a compact disc-interactive (CD-1) player is largely divided into block units, it can be divided into a base case unit 10 and a full motion video unit (FMV) unit 20. The base case unit 10 is used to play a CD-I base case disc recorded mainly on a still image, and the FMV unit 20 is an extension part for processing a moving image in the base case unit 10. Only used when played. In FIG. 1, the base case unit 10 processes a disk driver 12 for driving various compact disks, a system processor 11 for controlling a system, a ROM 13 for storing programs and data, and audio data. A CDIC 14, an audio mixer 15, a video data control block (VDSC) 16 for processing video data, and a video mixer 17 for reproducing data from the compact disc 12-2. An audio signal is output through the terminal 1 and a video signal is output through the video output terminal 2. In addition, the FMV unit 20 includes an MPEG audio decoder 1 and an MPEG video decoder 22 to process audio and video data when the disc for FMV is played to the audio mixer 15 and the video mixer 17. Print each. The power supply 30 inputs commercial and battery power to supply the required power to the base case 10 and the FMV unit 20, respectively. In the conventional compact disc player, when the player is turned on, the power supply device 30 always supplies power to the base case part 10 or the FMV unit 20 together. However, since the FMV unit 20 is used only in a specific disk, it is not necessary to supply power to the FMV unit 20 when not using the FMV disc. As such, the conventional power supply device 30 has a problem in that a large amount of power is unnecessarily consumed by supplying power even when the FMV unit 20 is not used. On the other hand, the compact disc player power supply control method disclosed in Patent Publication No. 2310 (Notice: 91-3462, Announcement Date: 1991.5.31) is a power supply by automatically shutting off the power when the disc player is powered and left for a certain time Although there is an advantage of preventing consumption, there was no function to prevent power consumption by cutting off the power supplied to blocks not used (eg FMV unit) according to the type of disk to be played.

Accordingly, an object of the present invention is to provide a compact disc interactive player having a function of preventing power consumption by cutting off power supply to blocks not used according to the type of compact disc in order to solve the conventional problems as described above.

Another object of the present invention is to provide a power supply of the compact disc interactive player to prevent power consumption by turning on and off the power supply according to the type of compact disc in order to solve the conventional problems as described above.

In order to achieve the above object of the present invention is a CD-I player that can play a variety of compact discs,

A base case unit which reproduces the compact disc interactive and outputs a power supply control signal according to the type of the disc; A power supply for outputting power for the player by inputting commercial and battery input power; Switching means for switching power applied from the power supply device according to a power supply control signal output from the base case unit; And an FMV unit for decoding and outputting MPEG power so that a power source switched from the switching means is input only when the disc is an FMV disc, so that video and audio data input from the disc can be realized as a complete moving picture.

In order to achieve the above object another object of the present invention is a compact disc interactive player,

A base case unit which reproduces the compact disc interactive player and outputs a power supply control signal according to the type of disc; A voltage generator for inputting commercial and battery power sources to generate a predetermined reference voltage; A base case power output terminal configured to input a reference voltage generated by the voltage generator to supply power to the base case of the compact disc interactive player; An FMV unit power output stage for supplying power to the FMV unit of the compact disc interactive player by inputting a reference voltage generated by the voltage generator according to the power supply control signal outputted from the base case bander; And an FMV unit for supplying power from the FMV unit power output stage only when the disc is an FMV disc to MPEG-decode and output the video and audio data input from the disc to realize a complete moving picture.

Next, the device of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram schematically showing the configuration of a CD-I player according to the present invention, and includes a base case unit 10, an FMV unit 20, a power supply device 30, and a switch 35. As shown in FIG. The base case unit 10 includes a disk driver 12 for driving the compact disk 12-2, a system processor 11 for controlling the system, a ROM 13 for storing programs and data, and a CDIC for processing audio data. 14, an audio mixer 15, a video data control block (VDSC) 16, and a video mixer 17 are used to reproduce data from the compact disc 12-2 and to output audio through the audio output terminal 1. A signal is output, and a video signal is output through the video output terminal 2. In addition, the FMV unit 20 includes an MPEG audio decoder 21 and an MPEG video decoder 22 to process audio and video data when the disc for FMV is played to the audio mixer 15 and the video mixer 17, respectively. Output The power supply device 30 supplies power to the base case part 10 by inputting commercial and battery power, and supplies power to the FMV unit 20 through the switch 35. The switch 35 determines the type of the disc 12-2 on which the microcomputer 12-1 of the disc driver 20 is to be played. If the disc is an FMV disc, the switch 35 is turned on to supply power to the FMV unit 20. If it is not a disk for FMV, it is 'off' to cut off the power.

In other words, the CD-I player is a home multimedia device that shows not only moving images but also audio and texts. ) You can play discs, base case CD-I discs, FMV CD-I discs, and so on. Therefore, when a disc is inserted into the player, the determination of the primary disc type is made through the microcomputer 21-1 to determine whether it is a CD-DA disc, a CD-G disc, or a disc other than the disc. In the case of a CD-I disc, the contents of the disc are displayed according to the application program on the disc. At this time, if the CD-I base case disk, under the control of the system processor 11, the data read from the disk driver 12 is first decoded by the CDIC 14, and the audio data is output through the audio mixer 15. . Video data is output to video mixer 17 after passing through video data control (VDSC) 16. The FMV block 20 does not perform any operation at this time, but only wastes power.

On the other hand, in the case of an FMV disc, the data passing through the CDIC 14 also uses the MPEG audio decoder 21, the MPEG video decoder 22, the VDSC 16, and even memory (RAM) belonging to them. The base case unit 10 is a part that performs a basic function of the CD-I disc player, so that the power is continuously supplied while the CD-I player is operating regardless of the type of the disc. That is, when the power is turned on in the CD-I player, the microcomputer 12-1 of the disc driver 12 distinguishes whether a disc is present or what disc. At this time, the microcomputer 21-1 may judge the type of the disc independently, or may depend on the compact disc-file manager (CD-FM) device driver (which is built-in software) included in the ROM 13 or the like. It may be. The microcomputer 12-1 determines the type of disk and outputs a power supply control signal to the switch 35 to supply power to the FMV unit 20 only when the disk is an FMV disk. Since the FMV unit 20 is valid only when a disc for FMV is loaded, there is no problem even if the power is turned off when other types of discs are played. The time to turn on / off the switch 35 can be made at every point in time when the disc must be determined. That is, each time the door is opened and closed to reset the system or the system is loaded, the disc type is determined, and power is supplied to or disconnected from the FMV unit 20.

3 is a block diagram showing another embodiment according to the present invention, and includes a base case part 10, an FMV unit 20, and a power supply device 30. In FIG. 3, the base case unit 10 and the FMV unit 20 are the same as those of FIGS. 1 and 2, and the power supply device 30 inputs commercial and battery power to generate a predetermined reference voltage. Input the output of the voltage generator 31 and the voltage generator 31 to input the output of the base case power output terminal 32 and the voltage generator 31 to supply power to the base case unit 10, the base case unit 10 FMV power output terminal 33 for supplying power only when the FMV disc is played in the FMV unit 20 according to the power supply control signal input from Therefore, when the FMV unit does not need to operate according to the type of the disc to be played, the power supply device 30 may prevent power consumption by cutting off the power supply.

As such, the present invention has an effect of preventing unnecessary power waste by cutting off power supplied to unused blocks according to the type of compact disc used for the CD-I.
