US Patent:

48211010, Apr 11, 1989

Filed:

Feb 19, 1987

Appl. No.:

7/016671

Inventors:

Michael P. Short - San Jose CA

Assignee:

Isix, Inc. - Foster City CA

International Classification:

H04N 704
H04N 5262

US Classification:

358181

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 need 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.

International Classification:

US Classification:

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 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 provide the appearance of continuous movement of displayed images. Digital data is included in the video fields to identify the particular fields occurring in an arbitrary sequence. 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-assembly correlated video fields of a selected displayable program from the arbitrary sequence of interleaved video fields is included in the digital data in the horizontal scans of traces of each video field in the sequence. Audio signals are included in the video fields of the displayable programs to provide correlated audio signals synchronized with the selected re-assembled video fields of the selected displayable program.
