Statistical remultiplexing with bandwidth allocation among different transcoding channels

摘要: An efficient statistical remultiplexer for processing a number of channels that include video data. In one aspect, transcoding the data is delayed while information obtained from Bit rate need parameters are determined based on information, and transcoded (110, 112, 200, 300) respective bit following delay. another frames updated plurality times at successive intervals to allow closer monitoring rate. Minimum maximum bounds rate, e.g., buffer overflow underflow protection, also in each interval. pre-transcoding quantization scales macroblocks frame scaled provide corresponding new ratio amount target, post-transcoding frame. The adjusted different poritons as progresses ensure minimum bandwidth allocated macroblock.
