Abstract

A two-way wireless local transmission system integrates computer and television user interfaces. A television set-top device includes a separate transmitter and receiver. The transmitter converts an audio and video signal into a modulated signal within the 902-928 MHz frequency band and transmits the modulated signal to a receiver associated with a computer peripheral device. The receiver downconverts the modulated signal and processes the signal within the computer. The computer processed signal is then sent by a transmitter in the computer peripheral device to the receiver in the set-top device, which provides the signal to a television receiver which displays images in response to the received signals.

Claims

1. A method of establishing a wireless connection between a video device and a computer, the method comprising the steps of:

receiving a television signal at a first location;

upconverting the television signal and transmitting the upconverted signal from the first location;

receiving the upconverted signal at a second location, wherein the upconverted signal is downconverted;

processing the downconverted signal with the computer to produce digital video data;

converting the digital video data into analog composite video, wherein the analog composite video is upconverted and transmitted from the second location; and

receiving the upconverted analog composite video at the first location, wherein the upconverted analog composite video is downconverted and input into a video device.

2. The method of claim 1, wherein the processing step further comprises the steps of:

tuning the downconverted signal to provide an analog composite video signal;

separating the analog composite video signal into vertical blanking interval data and a digital video signal;

manipulating the vertical blanking interval data within the computer to create digital data; and

combining the digital data with the digital video signal to create the digital video data.

3. The method of claim 1, wherein the television signal is transmitted within the 902-928 MHz frequency band.

4. The method of claim 1, wherein the analog composite video is transmitted within the 902-928 MHz frequency band.
