Abstract
Abstract An improved system, apparatus and method are disclosed for interleaving selected video fields of multiple displayable programs to facilitate viewer selection of which programs to display. Selected video fields are stored and continuously displayed until a new, successive video field is selected to update the currently stored video field. In this manner, a sequence of rapidly updated, fixed or frozen video fields provides the appearance of continuous movement of displayed images. Audio signals are included in the video fields of displayable programs to provide audio signals in synchronism with selected video fields. The sequence of interleaved video fields may be assembled in real time or stored as a video tape recording, and the information needed to re-assemble correlated video fields of a selector displayable program from the sequence of interleaved video fields is included in the horizontal scans or traces of each video field in the sequence.
