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 1st encoded signal having a 1st varying relative bit rate. The processing continues by receiving a 2nd encoded signal having a 2nd varying relative bit rate. For example, the 1st and 2nd encoded 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 1st and 2nd encoded signals based on reducing cumulative peak bit rates of the 1st varying relative bit rate and the 2nd varying relative bit rate. For example, the 2nd encoded signal may be delayed via buffering to ensure that the I frames of the 1st and 2nd encoded signals are misaligned.
