ENCODING VARIABLE-LENGTH CODES WITH EFFICIENT MEMORY USAGE Russian patent published in 2011 - IPC H03M7/40 

FIELD: information technology.

SUBSTANCE: invention is aimed at methods for adaptive variable-length coding (VLC) with efficient memory usage and low degree of complexity with respect to data for different fields of application, such as digital video data, image data, audio and voice data. In certain aspects, these methods can employ properties of defined sets of code words to support very compact data structures. In other aspects, the methods can support adaptive coding and decoding with low degree of complexity with respect to binary sequences generated by memoryless sources.

EFFECT: adaptive variable-length coding with more efficient memory usage and low complexity for data in different fields of application, such as coding digital video data, image data, audio or voice data.
