A portable television playback system includes a video source unit, video processing circuitry, audio processing circuitry, and a stereo viewing and sound unit. The video source unit is a television receiver, a small videocassette tape cartridge player, or a stereo optical video disc player. The viewing and sound unit has stereoscopic and stereophonic capabilities and is generally a head worn unit having right and left image display devices and right and left earphones. The video and audio processing circuits receive the signals from the video source unit and parallel the video and audio signals to drive the stereo output devices if the source is a television receiver or a videocassette tape player or perform demultiplexing functions to separate the right and left video and audio signals from the right and left multiplexed video/audio signals. The video source unit and the video and audio processing circuits are packaged in a single portable case which may be connected to the head worn viewing and sound unit by an appropriate cable for use.
