Apparatus and method for data decoding

摘要

A computer-implemented method comprises receiving a data stream that includes a series of code words that encodes a respective series of pixel data according to a first entropy coding lookup table, and processing the data stream to determine if there is a match between a first code word and a consecutive second code word, and a code word entry in a second entropy coding lookup table. The method also includes, if there is a match, decoding the first code word and the second code word using the second entropy coding lookup table. Further, the method includes, if there is not a match, decoding the first code word using the first entropy coding lookup table.

1. A computer-implemented method comprising:
receiving, by a computing device, a data stream that includes a series of code words that encode a respective series of pixel data according to a first entropy coding lookup table; processing, by the computing device, the data stream to determine if there is a match between a first code word and a second code word, and a code word entry in a second entropy coding lookup table, wherein the first code word and the second code word are consecutive code words in the data stream, and wherein the second entropy coding lookup table is different than the first entropy coding lookup table; if there is a match between the first code word and the second code word, and a code word entry in the second entropy coding lookup table, decoding, by the computing device, the first code word and the second code word using the second entropy coding lookup table; and if there is not a match between the first code word and the second code word and a code word entry in the second entropy coding lookup table, decoding, by the computing device, the first code word using the first entropy coding lookup table.
