Abstract

A computer system. The computer system comprises a display device for image display, a storage device to store a video signal, and a video-playing subsystem, wherein power is supplied to the display device, the storage device, and the video-playing subsystem. The video-playing subsystem comprises a digital video recording (DVR) module to process the video signal transmitted from the storage device in a video-playing mode, and to output the audio signal and the image signal of the video signal respectively, and an image-processing module to process the image signal transmitted from the DVR module into an image for image display.

Claims

1. A computer system, comprising:

a display device for image display;

a storage device to store a video signal; and

a video-playing subsystem, comprising;

a digital video recording (DVR) module to process the video signal transmitted from the storage device in a video-playing mode, and to output the audio signal and the image signal of the video signal respectively; and

an image-processing module to process the image signal transmitted from the DVR module into an image for image display,

wherein a power is supplied to the display device, the storage device and the video-playing subsystem.

2. The computer system as claimed in claim 1, further comprising a central processing device to load an operating system and control image data when the computer system is fully powered, wherein the central processing device transmits the video signal stored in the storage device to the DVR module of the video-playing subsystem to process the video signal into an image for display.

3. The computer system as claimed in claim 1, further comprising a control panel having a plurality of control buttons for various playing functions during the video-playing mode.

4. The computer system as claimed in claim 3, wherein the video-playing subsystem further comprises a detecting device to detect the control buttons during the video-playing mode for various playing functions.

5. The computer system as claimed in claim 1, wherein the video-playing subsystem further comprises a wireless signal detecting device to detect a plurality of wireless signals during the video-playing mode for various playing functions.

6. The computer system as claimed in claim 1, further comprises an audio-playing device to play the audio signal transmitted from the DVR module.

7. The computer system as claimed in claim 6, wherein video-playing subsystem further comprises:

a TV image module coupled to a TV signal receiving device to respectively output an audio signal, and an image signal of a received TV signal during a TV play mode and to simultaneously output the audio signal and the image signal of the received TV signal during a TV recording mode,

wherein the DVR module outputs the audio signal transmitted from the TV image module to the audio-playing device during the TV play mode, storing the audio and image signals from the TV image module into the storage device during the TV recording mode, and processing the TV signal from the TV image module into an image for display by the display device during the TV play mode.

8. The computer system as claimed in claim 7, further comprises a control panel having a switch button and a plurality of control buttons, wherein the switch button is for switching among the TV play mode, TV recording mode and the video-playing mode, while the control buttons are for various playing functions during the TV play mode, TV recording mode and the video-playing mode.

9. The computer system as claimed in claim 7, wherein the video-playing subsystem further comprises a detecting device to detect a control signal entered by the control panel for switching among the TV play mode, TV recording mode and the video-playing mode or for various playing functions during the TV play mode, TV recording mode and the video-playing mode.

10. The computer system as claimed in claim 7, wherein the video-playing subsystem further comprises a wireless signal detecting device to detect a plurality of wireless control signals for various playing functions during the TV play mode, TV recording mode and the video-playing mode.

11. The computer system as claimed in claim 7, wherein the computer system enters the TV play mode, TV recording mode or the video-playing mode without loading an operating system.

12. The computer system as claimed in claim 1, wherein the computer system enters the video-playing mode without loading an operating system.

13. A computer system, comprising:

a display device for image display;

an audio-playing device to play an audio signal;

a storage device for a video signal storage; and

a video-playing subsystem, comprising;

a TV image module coupled to a TV signal receiving device to respectively output an audio signal and an image signal of a received TV signal during a TV play mode, and to simultaneously output the audio signal and the image signal of the received TV signal during a TV recording mode;

a DVR module to output the audio signal from the TV image module to the audio-playing device during the TV play mode, storing the audio and image signals from the TV image module into the storage device during the TV recording mode, and processing the video signal from the storage device to respectively output an audio signal and an image signal of the video signal during a video-playing mode, wherein the audio signal is output to the audio-playing device; and

an image-processing module to process the TV signal from the TV image module into an image for display by the display device during the TV play mode, and to process the image signal from the DVR module into an image for display by the display device during the video-playing mode;

a central processing device to load an operating system and control image data when the computer system is fully powered, wherein the central processing device, controlling to play or to store the received TV signal in the TV image module, transmits the video signal stored in the storage device to the DVR module of the video-playing subsystem to process the video signal into an image for display,

wherein the computer system is not fully powered during the TV play mode, TV recording mode and the video-playing mode.

14. The computer system as claimed in claim 13, further comprises a control panel having a switch button and a plurality of control buttons, wherein the switch button is for switching among the TV play mode, TV recording mode and the video-playing mode, while the control buttons are for various playing functions during the TV play mode, TV recording mode and the video-playing mode.

15. The computer system as claimed in claim 14, wherein the video-playing subsystem further comprises a detecting device to detect a control signal entered by the control panel for switching among the TV play mode, TV recording mode and the video-playing mode or for various playing functions during the TV play mode, TV recording mode and the video-playing mode.

16. The computer system as claimed in claim 13, wherein the video-playing subsystem further comprises a wireless signal detecting device to detect a plurality of wireless control signals for various playing functions during the TV play mode, TV recording mode and the video-playing mode.

17. The computer system as claimed in claim 13, wherein the computer system enters the TV play mode, TV recording mode or the video-playing mode without loading an operating system.
