Abstract
A method and apparatus for distributed load multiplexing of multiple encoded signals over a shared communication path include processing that begins by receiving a 1encoded signal having a 1varying relative bit rate. The processing continues by receiving a 2encoded signal having a 2varying relative bit rate. For example, the 1and 2encoded signals may be an MPEG encoded signal including a plurality of I frames, B frames and P frames. The processing continues by aligning multiplexing of the 1and 2encoded signals based on reducing cumulative peak bit rates of the 1varying relative bit rate and the 2varying relative bit rate. For example, the 2encoded signal may be delayed via buffering to ensure that the I frames of the 1and 2encoded signals are misaligned.
