Statistical remultiplexing with bandwidth allocation among different transcoding channels

Abstract From the Canadian patent

An efficient statistical remultiplexer for processing a number of channels that include video data. In one aspect transcoding of the video data is , delayed while statistical information is obtained from the data. Bit rate need parameters for the data are determined based on the statistical information and the video data is transcoded (110, 112 200, 300) based on the respective , bit rate need parameters following the delay. In another aspect a transcoding , bit rate for video frames is updated a plurality of times at successive intervals to allow a closer monitoring of the bit rate. Minimum and maximum bounds for the transcoding bit rate, e.g. for buffer overflow and underflow …
