Title
(EN) Stereoscopic television system
Abstract
(EN)

An improved stereoscopic television system is disclosed, having a great deal of compatibility with the existing commercial television infrastructure. Flicker is eliminated while preserving the existing bandwidth allowing the stereoscopic video signals to be handled with conventional apparatus such as video tape recorders, video disks, or broadcast equipment. In the present invention the number of fields per second is twice that of he standard field rate. When displayed on an unmodified receiver or monitor, each subfield image appears to be anamorphically compressed in the vertical direction by a factor of two. A blanking area and/or vertical sync pulse separates the two subfields.
