A multipurpose computerized television system generates a plurality of video images in association with a personal computer. A television circuit associates with the personal computer and is within the personal computer chassis for receiving a plurality of television signals and directing the signals to the monitor for the monitor to display. An audio multimedia circuit associates with the personal computer and the television circuit and is also located within the chassis for receiving and processing audio data from the television circuit. The audio multimedia circuit also communicates the audio multimedia data to the personal computer. Control circuitry associated with the television circuit and the personal computer within the chassis controls the operation of the television circuit through the personal computer. The control circuitry comprises a remote control circuit for remotely and independently controlling the television circuit and the personal computer.
