Brian Astle: Run-length encoding sequence for video signals. Intel Corporation, Steve Mendelsohn, William H Murray, September 3, 1996: US05552832 (120 worldwide citation)

Regions of a video frame are classified into different classes of regions (e.g., inter encoded blocks, intra encoded blocks, and skip blocks). The classes of regions are then run-length encoded using an encoding sequence that is a function of the content of the video frame. The run-length encoded si ...

John G Apostolopoulos: Video communication using multiple streams. Hewlett Packard Development Company, August 26, 2003: US06611530 (91 worldwide citation)

A video communication system that uses multiple streams to carry digital video. The use of multiple streams ensures that errors in one or more of the multiple streams do not prevent reconstruction of remaining ones of the multiple streams. This enables an error free display of the digital video at a ...
