SYSTEM AND METHOD FOR THE APPLICATION OF A STATISTICAL MULTIPLEXING ALGORITHM FOR VIDEO ENCODING

摘要

A system and method for statistical-multiplexing, comprising a multi-criteria optimization algorithm for video bit stream control, and an alignment of average video bit-stream rates with treatment priorities of cascaded multiplexer's inputs (21, 22, 23). The first criterion is a grouping of the encoders (10, 20, 30) in accordance with the content recipient's wishes. The second criterion involves adjusting the proportions of the average bit rates of the bit streams (110, 120, 130), wherein these proportions are represented in the form of integer-to-integer fractions, in accordance with the calculated optimal scanning arrays (160) of a plurality of said cascaded multiplexers (40). The third criterion involves a definition of different bit-rate ranges for different groups of encoders (10, 20, 30) and maintaining the average bit rates for each group of encoders according to flexible bit rate ranges, thereby enabling adjustment of the proportions of the average bit rates in the form of integer-to-integer fractions, so that a laminar bit stream is provided as the output (140) of the last of the cascaded multiplexers.
