Patent ID: 7098968

Claim:
A TV image conversion device for turning a computer on or off by means of a multimedia remote control, the multimedia remote control including a computer on-off switch, the TV image conversion device being electrically coupled to a computer, and the TV image conversion device including basic control circuits and components required by a conventional TV image conversion device, the TV image conversion device further comprising: a wireless signal receiver for receiving a turn-on or turn-off signal transmitted from the multimedia remote control; a wireless signal decoder for converting the turn-on or turn-off signal transmitted from the wireless signal receiver into a control signal; and a signal transmission line for sending the control signal transmitted from the wireless signal decoder to the computer; wherein the computer on-off switch is operative when pressed to cause the multimedia remote control to generate a turn-on or turn-off signal which is transmitted to the wireless signal receiver, the turn-on or turn-off signal is sent from the wireless signal receiver to the wireless signal decoder for converting the turn-on or turn-off signal is converted into a control signal, the control signal is sent to a predetermined pin in the computer for enabling the predetermined pin, the enabled predetermined pin generates a trigger signal by either converting a high voltage level into a low voltage level or converting a low voltage level into a high voltage level, and the computer is enabled by the trigger signal to perform a turn-on or turn-off step, wherein the TV image conversion device is a TV card and the signal transmission line includes a signal line having one end coupled to the wireless signal decoder and the other end coupled to the wireless signal receiver so that responsive to pressing the computer on-off switch of the multimedia remote control, a setup program in an embedded BIOS of the computer is operative to set the predetermined pin to an enabled state based on a state of the signal line and cause the BIOS to turn on the computer.
