Abstract

A TV card for a computer, comprising a TV signal receiving part receiving a TV signal; a TV signal processing part processing the TV signal from the TV signal receiving part; a TV encoder converting a video signal outputted from the TV signal processing part into a TV video signal suitable for display, and directly transmitting the converted video signal to an output part of a TV; a control program storage part storing a control program controlling the TV signal received from the TV signal receiving part to be displayed on the TV through the TV signal processing part and the TV encoder; and a control part controlling the TV signal to be displayed on the TV through the TV signal processing part and the TV encoder on the basis of the control program when electric power is supplied thereto. With this configuration, it is possible not only to watch TV without booting the computer system but also to work with the computer system while watching TV.

a control part controlling the TV signal to be displayed on the TV through the TV signal processing part and the TV encoder on the basis of the control program.

2. A computer system having a power supply and a display apparatus including a TV and a monitor, and a graphic card outputting a video signal to the monitor, comprising:

a TV card comprising;

a TV signal receiving part receiving a TV signal,

a TV signal processing part outputting the video signal to the graphic card after processing the TV signal from the TV signal receiving part,

a TV encoder converting the video signal outputted from the TV signal processing part into a TV video signal suitable for display, and directly transmitting the converted video signal to an output part of a TV,

a control program storage part storing a control program controlling the TV signal received from the TV signal receiving part to be displayed on the TV through the TV signal processing part and the TV encoder, the control program stored in the control program storage part of the TV card includes a remote signal processing routine for processing a predetermined remote signal, and processes the remote signal through the remote signal processing routine when the remote signal is inputted, and

a first control part controlling the TV signal to be displayed on the TV through the TV signal processing part and the TV encoder on the basis of the control;

a selection part for selecting a TV function; and

a second control part controlling the supply of electric power to the TV card and the display apparatus when the TV function is selected through the selection part.

3. The computer system according to claim 2, wherein the selection part includes a remote controlling unit and a remote signal receiving part receiving a remote signal from the remote controlling unit, and the second control part controls the electric power supplied to the TV card on the basis of a control signal outputted from the remote signal receiving part.

4. A television card in a computer remotely controlled by a personal computer remote controller, said television card comprising:

a television signal tuner receiving a television signal;

a television signal processor processing said television signal from said television signal tuner;

a television encoder converting a video signal output from said television signal processor into a converted video signal suitable for display on a television, and directly transmitting the converted video signal to an input of said television;

a control program storage part storing a control program; and

a control part controlling, on the basis of said control program, said television signal tuner, said television signal processor and said television encoder, said television card having electric power supplied thereto absent said computer being booted.

5. The television card as set forth in claim 4, wherein said control program of said control program storage part includes a remote signal processing routine for processing a remote control signal generated by said personal computer remote controller.

6. The television card as set forth in claim 4, said television signal processor comprising:
