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.
