Abstract

A stereoscopic video telecommunication system includes a fiberoptic based wideband switching network interconnecting wideband subscriber stations and narrowband subscriber stations. A wideband station includes a stereoscopic video receiver along with a stereophonic audio receiver for respectively displaying and playing stereo video and audio signals received by way of the network. The wideband station may also include a stereoscopic video source such as a pair of stereoscopic video cameras along with a stereophonic pair of microphones. The wideband station may also include narrowband devices such as a conventional telephone, a computer, and a facsimile machine. Connections between stations on the network are established by dialing another station and transferring the desired signal, including stereoscopic video signals. Preferably, the signals are converted to a digital format and, especially for stereoscopic video signals, data compressed to conserve network overhead.
