Abstract
Disclosed herein is a computer capable of transmitting and receiving video and audio signals over an RF bandwidth. The RF bandwidth is allocated among the audio and video signals to allow the audio and video signals to be fitted within the RF bandwidth. The allocation is performed by varying the rates of compression of the audio and video signals. The video is displayed by using fast digital-to-analog converters and a dither technique. An existing computer can be configured for wireless communications by inserting into its backplate a board including a transceiver for transmitting and receiving compressed audio and video signals. The computer's microprocessor is programmed to perform the bandwidth allocation, and can even be programmed to compress and decompress the audio and video signals.
