Abstract:
1. A method for allocating bits in a statistical multiplexer comprising: allocating a first bit rate allowed for the output of each of a plurality of encoders supplying a multiplexer during a first time period; determining a bit rate increase from the first bit rate for each of the encoders; and allocating a second bit rate allowable to each of the encoders for a second time period, subsequent to the first time period, wherein the second bit rate is limited by the determined bit rate increase, wherein misalignment of application of the second bit rate to a given one of the encoders can cause the second bit rate output to be provided in the first time period by the given encoder, and wherein the bit rate increase is determined so that when the misalignment of the second bit rate can occur for the second bit rate to be output in the first time period, the bit rate increase is set so that a total number of bits processed by the given encoder using the second rate does not exceed the encoder capacity that will cause bits to be dropped by the multiplexer.
