摘要： A method includes receiving an input data stream at a processor, and for each byte sequence from a plurality of byte sequences of the input data stream, a hash is generated and compared to a hash table to determine whether a match exists. If a match exists, that byte sequence is incrementally expanded to include one or more additional adjacent bytes from the input data stream, to produce multiple expanded byte sequences. Each of the expanded byte sequences is compared to the hash table to identify a maximum-length matched byte sequence from a set that includes the byte sequence and the plurality of expanded byte sequences. A representation of the maximum-length matched byte sequence is stored in the memory. If a match does not exist, a representation of that byte sequence is stored as a byte sequence literal in the memory.

摘要： A digital video apparatus (50) provides reduced channel change times. According to an exemplary embodiment, the digital video apparatus (50) includes at least one receiver (52, 60) for receiving first and second video streams (12, 14) representing the same program, wherein the first video stream (12) has at least one characteristic different from the second video stream (14); a first signal processor (54, 56, 58) for processing the first video stream (12) to generate a first processed video stream; a second signal processor (62) for processing the second video stream (14) to generate a second processed video stream having a delay with respect to the first processed video stream; a renderer (66) for rendering the second processed video stream responsive to a channel change command; and a switch (64) for switching from the second processed video stream to the first processed video stream after the renderer (66) begins rendering the second processed video stream, and thereby causing the renderer (66) to begin rendering the first processed video stream.
