Abstract

The subject invention relates to a type of radio computer audio-video transmission device, comprising a transmitter and a receiver, wherein the transmitter includes a 2.4 GHZ transmitting antenna, a UHF receiving antenna, a VGA and A/V output, a computer control output, a power input, a power output, an infrared output and such components, said transmitter serving to convert the computer images appearing on the computer monitor, through various processes, into 2.4 GHZ microwave demodulated signals, and transmit them through 2.4 GHZ transmitting antenna to the receiver; and when the receiving antenna of the 2.4 GHZ receiver receives the signals, the signals are then amplifyd and demodulated into general A/V output and transmitted to the TV; the receiver includes a 2.4 GHZ receiving antenna, a UHF transmitting antenna, an infrared ray inductor, an A/V output port and a power remote-control switch; said receiver serves to enable the infrared ray inductor to receive the infrared ray signals emitted from the infrared ray keyboard or the infrared ray mouse, and convert them into UHF remote-control signals, and transmit them through the UHF transmitting antenna to the transmitter; when the transmitter'"'"'s UHF receiving antenna receives the signals, they are amplifyd, demodulated and transmitted to the keyboard control signals that are acceptable to general computers, and transmitted to the computer, so that the user may be able to pick up data or images from the computer monitor, by remote-controlling the computer through an infrared ray keyboard or infrared ray mouse, and display them onto the TV screen.

Claims

1. A radio computer audio-video transmission device, comprising:

a transmitter, its interior circuit components composed of a 2.4 GHZ transmitting antenna, a UHF receiving antenna, a VGA and A/V input, a computer control output, a power input, a power output connected to an infrared ray output, wherein the computer control output can be connected to the computer main unit, the computer main unit being connected to a computer monitor to enable controlling of all computer operations, the power of the computer main unit being connected to a transmitter to receive commands for switching on operation, said transmitter serving to convert the images appearing on the computer monitor, after being subjected to processing, into 2.4 GHZ microwave demodulated signals, and then transmitted from the 2.4 GHZ transmitting antenna;

or serving to demodulate, amplify and convert the signals received by the UHF receiving antenna into control signals that can be accepted by general computers, and display them onto the computer monitor; and

a receiver, its interior circuit components composed of a 2.4 GHZ receiving antenna, a UHF transmitting antenna connected to an A/V output port, wherein the A/V output port being connected to an A/V appliance equipped with A/V input terminal, said receiver serving to, with its interior circuit component of an infrared ray inductor, receive the infrared ray signals emitted by the infrared ray keyboard or the infrared ray mouse, and convert them into UHF remote-control signals, and transmit them through the UHF transmitting antenna;

or serving to demodulate and amplify the signals, after they are received by the 2.4 GHZ receiving antenna, and process them into general A/V output, and transmit them to the A/V appliance;

whereby, the user picks up data or images from the computer and displays them, by remote-control of the computer through an infrared ray keyboard or an infrared ray mouse, on the existing A/V appliance.

2. The radio computer audio-video transmission device, as recited in claim 1, wherein the receiver may include a power remote-control switch, so that the receiver may transmit signals through UHF to the transmitter, or may send control commands through UHF to switch on or off the computer.

3. The radio computer audio-video transmission device, as recited in claim 1, wherein the A/V appliance can be a TV set.

4. The radio computer audio-video transmission device, as recited in claim 1, wherein the transmitter may be connected through an infrared ray output terminal to the infrared ray transmitter, to facilitate the user to control the computer.
