Filed: 2005-06-03
Abstract: A video compression system for compressing a stream of digital video data is disclosed. Known run-length encoding is applied whenever possible to the digital video data stream (62). When a run is not identified, the encoder determines whether a consecutive series of pixels are identified from only two different colors, and if so creates a make-series command to create bytes with bits encoded as a stream of binary values corresponding to the two pixel colors as they occur in the consecutive series (64). The make series command continues for as many bytes as the consecutive series of bits will fill, except that, when a make series command applies again to a byte of make-series bits, the make series command is preempted by the applicable run length encoding (65).
