IMPROVEMENTS TO REPRESENTATIONS OF COMPRESSED VIDEO

摘要

A method of compressing digital data comprising the steps of (i) reading digital data as series of binary coded words representing a context and a codeword to be compressed, (ii) calculating distribution output data for the input data and assigning variable length codewords to the result; and (iii) periodically recalculating the codewords in accordance with a predetermined schedule, in order to continuously update the codewords and their lengths.
