Abstract

A method and apparatus for performing arithmetic encoding and / or decoding is disclosed. In one embodiment, a method of encoding data includes encoding a plurality of events in a sequence of events to produce encoded data, and using the encoded data to produce a bitstream includes adding zero or more padding bits to the bitstream After the encoded data in , wherein the zero or more padding bits operate to substantially preserve the relationship between the amount of encoded events, the number of blocks being encoded, and the number of bits in the bitstream.

Description

[0001] Part of the patented document contains materials protected by copyright.The copyright owner does not oppose anyone who is disclosed by the patent document or patent to fax and reproduce. Because it is open in patent documents or records or records of the patent and trademark bureau, all copyrights must be retained anyway. [0002] The present invention requires the corresponding temporary patent application number of ″ Termination ofarithmetic Coding and Byte Stuffing ″ The corresponding temporary patent application number 60 / 412,245, and the title of Cabaccleanup and Complexity Reduction ″ on October 4, 2002, 2002Temporary patent application sequence number 60 / 415,999 priority. Technical field [0003] The present invention usually involves information theory, video compression and arithmetic coding.More specifically, the present invention involves the method and equipment of formation and use of status machines for arithmetic coding (Termination) and byte filling during ar...
