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