Description

System of merging computer and DVD player combined with DVD player function

The present invention relates to a system having both a computer function and a DVD player function, and more particularly, to a system for sharing a DVD driver while operating on independent power supplies.

In general, DVD is divided into two types of playback-only and recordable / playback. The method of recording information on a playback-only optical disc includes a pit by counting a groove called a pit on the disk. A portion (land) having no pit at " 0 " corresponds to " 1 ". At the time of reproduction, " 1 " and " 0 " In a phase change optical disk capable of recording / erasing, the recording film of the disk is changed into two states, crystalline and amorphous, by the heat of the laser, and corresponds to " 1 " and " 0 ", respectively. In the method of reproducing a phase change disc, information is judged by a difference in reflection amount in the same way as a reproduction-only disc. The reflection amount in the crystal state is larger than the reflection amount in the amorphous state. It is possible to selectively give the recording film one of a crystalline and an amorphous state by adjusting the power of the laser during recording.

Modulation is a technique for removing direct current (DC) components when recording baseband signals onto discs on CDs or DVDs. In CDs, EFM (modulated 8-bit data from a 14-bit signal) is recorded. Eightplus Fourteen Modulation (Eight to Fourteen Modulation) is used, and DVD employs EFMplus, which modulates the original 8-bit into a 16-bit signal.

On the other hand, CD-ROM is widely used as a storage medium of a computer, but as DVD-ROM technology is stabilized, a DVD-ROM having a much larger storage capacity is gradually used. In the case of a computer incorporating a DVD-ROM as described above, the DVD-ROM operates as a power source of the computer. In addition, since the DVD player is used separately from the computer, the space occupied by the computer and the DVD player is large, and there is a problem that the overall cost increases.

SUMMARY OF THE INVENTION The present invention aims to provide a system that is compact in installation space and easy to use by combining a computer and a DVD player and operating by independent power sources to solve the above problems.

The play related buttons 405 include a fast play button, a slow play button, a pause button, and a stop button. Buttons, skip buttons, and so on.

Figure 5 is a block diagram showing the configuration of the system according to the present invention, the system of the present invention is largely as shown in Figure 5, the power supply unit 510, computer unit 520, front panel 530, DVD player The DVD player 540 includes a DVD deck 541, a DVD control board 542, and an MPEG card 550.

The power supply unit 510 includes a first switching mode power supply device SMPS1 512 for supplying power to the computer unit 520 and a second switching mode power supply device SMPS2 for supplying power to the DVD player unit 540. 514). When the computer (PC) power button 208 of the front panel 530 is turned on, the first switching mode power supply 512 supplies power to the computer unit 520 and the DVD control board 542 to provide computer functions and DVD. Turn on the ROM function. When the DVD power button 204 of the front panel is turned on, the second SMPS 514 supplies power to the DVD control board 542 and the MPEG card 550 to turn on the DVD player function. At this time, if both the computer power button 208 and the DVD power button 204 are turned on, the DVD control board 542 controls the DVD deck 541 to operate as a DVD player. In other words, the operation as a DVD-ROM is stopped. Even if the computer power button 208 is turned off, the DVD player function continues to operate. On the contrary, even if the DVD power button 204 is turned off, the computer function continues to operate and the DVD control board 542 moves the DVD deck 541. Make it act as ROM.

The DVD player unit 540 includes a DVD deck unit 541, a DVD control board 542, and an MPEG card 550, and the MPEG 550 card includes an MPEG decoder 543 and video / audio (A / V). A separation unit 544, a video decoder 545, an NTSC encoder 546, an audio decoder 547, a digital-to-analog converter (DAC) 548, and a switch 549 are included. The DVD control board 542 controls the overall operation of the DVD, and the MPEG decoder 543 decodes the data compressed and stored on the DVD again. The A / V separator 544 separates and outputs audio data and video data, and the audio decoder 547 decodes the audio data. The digital-to-analog converter 548 converts digital audio data into analog and outputs the analog-converted audio signal to an audio output terminal (Audio Out). The video decoder 545 receives and decodes the digital video data, and the NTSC encoder 546 receives the video data, generates a composite video signal of the NTSC method, and outputs the composite video signal to the video output terminal. The switch 549 selects an output of the NTSC encoder 546 or a video signal input from the computer unit 520 according to the control signal of the proton panel 530 and outputs the video signal to the TV. Accordingly, the TV may display the screen by the DVD during the DVD play, and then display the screen provided by the computer together with the monitor when the DVD play is finished. The DVD deck 541 loads and ejects a DVD disc into a tray according to a user's operation, and drives the disc to rotate during play.

The front panel 530 operates by receiving power from the computer unit 520 or the DVD player unit 540, receives a remote control operation signal, and transmits the signal to the DVD controller 542 to provide a computer peripheral device such as a keyboard or a mouse. Provides a connection port for connecting.

The computer unit 520 includes a main board 522, a VGA card 524, a TV output card 526, a modem 528, etc., and an operating system such as Windows (O / S) and various application programs. It is mounted and operates as a computer. The main board 522 has an input / output slot for connecting various peripheral devices, and is equipped with elements necessary for computer functions such as a main CPU and various memories. The modem 528 is implemented as a 56K modem, a cable modem, an ADSL modem, or the like. Access to the Internet 110 to receive Internet services.

6 is a flowchart illustrating an operating procedure of the system according to the present invention.

6, if the DVD power button 204 is on, the second SMPS 514 is turned on to operate as a DVD player, and if the DVD power button 204 is off, the computer power button 208 is on. (601, 602, 603, 607). When the computer (PC) power is turned on, the first SMPS 512 is turned on to supply power to the PC main body 520, and to supply power to the control board 542 of the DVD player unit to perform at least a function as a DVD-ROM. (608, 609, 610). The ROM BIOS and the operating system are then driven to operate as a normal computer (611, 612).

When the DVD power button 204 is turned off, it is determined whether the computer (PC) power is on. If the power supply is turned on, the DVD power button 204 is turned on. ). When the computer (PC) power is turned off, it is determined whether the DVD power is on, and if the DVD power is on, it continues to operate as a DVD player (614,615,616).

As described above, according to the present invention, the power supply unit for the computer function and the power supply unit for the DVD player are independently provided so that each function operates independently in one main body, so that the computer and the DVD player can be installed at the same time. There are advantages to installing a system. In particular, in response to the recent trend of combining a computer and a home appliance, it is possible to surf a web through the Internet while watching a movie or music with a DVD player. In addition, the DVD player continues to operate even when the computer is turned off. On the contrary, the DVD operates as a DVD-ROM while the computer continues to operate even when the computer is turned off.
