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.
