Webcoders using sub-frames, there is some dependency between source symbols within a frame and the method proposed in [5] can not easily exploit it. A simpler but sub-optimal approach is to consider only the statistics of pairs of bits. Doing so, one can sub-optimally exploit the residual redundancy at the symbol level (i.e. blocking fire hydrant virginiaWebThe algorithm can satisfy all the requirements only insofar as it achieves the high compression associated with interframe coding, while not compromising random access for those applications that demand it.
