Description: 
A multi-channel bit rate distribution / truncation methodology named Prioritized Bitrate Distribution / Truncation is proposed. By distribution the bitrates to each channel according to the average value of maximum bit-plane levels and truncating the bitstreams proportional to their original lenght, the coding is performed in a perceptually much efficient manner.
