Abstract
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 Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
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.
Claim 2
Independent Claim
114 words
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.
Claim 3
Dependent Claim
70 words
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.
Claim 4
Dependent Claim
17 words
The method of claim 1, wherein the television signal is transmitted within the 902-928 MHz frequency band.
Claim 5
Dependent Claim
18 words
The method of claim 1, wherein the analog composite video is transmitted within the 902-928 MHz frequency band.
