Abstract
Methods and systems for improving coding decoding efficiency of video by providing a syntax modeler, a buffer, and a decoder. The syntax modeler may associate a first sequence of symbols with syntax elements. The buffer may store tables, each represented by a symbol in the first sequence, and each used to associate a respective symbol in a second sequence of symbols with encoded data. The decoder decodes the data into a bitstream using the second sequence retrieved from a table.
Claims1
A decoding system for decoding received encoded data, said system comprising:
- (a) a syntax modeler for associating a sequence of first symbols with syntax elements from said data;
- (b) at least one buffer for storing a plurality of tables, each nested within a respective one of said sequence of first symbols, and each used to associate a respective one of a sequence of second symbols with encoded data;
- and
- (c) a decoder that decodes said data into a bitstream using a selected respective one of said sequence of second symbols retrieved from a respective one of plurality of tables, where said bitstream is free from including any of said sequence of first symbols.
