Abstract
A method and apparatus for time multiplexing and demultiplexing two channels of picture information within a standard video channel. The method is specifically designed for field sequential stereoscopic display applications, but may be used for non-stereoscopic applications where conservation of bandwidth is required. The technique is superior to prior art commercially available stereoplexing approaches, and increases vertical resolution while decreasing stair-stepping of diagonal lines. The demultiplexing display controller of the invention can be manufactured at a low cost because its design takes advantage of commercially available integrated circuits.
