Abstract:
1. A method for decoding a multimedia communication signal comprising a sequence of frames generated using a multi-layer protocol stack, the multilayer protocol stack comprising a first error correction (EC) layer and at least one upper layer, the method comprising: a) performing an EC decoding of one or more first frames of the signal at the first EC layer to obtain one or more first EC decoded frames; b) processing the one or more decoded frames at the at least one upper layer to identify therein a plurality of persistent bits, and saving said plurality of persistent bits in memory; and, c) performing an iterative EC decoding of a second frame at the first error correction layer using one or more saved persistent bits to obtain a second EC decoded frame, wherein the second frame is different from any one frame from the one or more first frames; wherein step (c) comprises:
