Claim Text:
1. An apparatus comprising: a divider to segment an input video stream into a plurality of partitions; a channel analyzer coupled to the divider wherein the channel analyzer decomposes each of the plurality of partitions into at least two sub-bands using spatial frequency decomposition, wherein the channel analyzer includes a respective sampler that samples a respective partition by a factor corresponding to a number of sub-bands so that a total number of samples in all sub-bands is the same as the number of input samples of the input video stream; and a plurality of encoders coupled to the channel analyzer, each encoder of the plurality of encoders configured to encode one of the at least two sub-bands into an encoded bitstream to produce a plurality of encoded bitstreams, wherein each encoder utilizes coding information from at least one of the two sub-bands in encoding the at least two sub-bands to form the plurality of encoded bitstreams; and a reconstruction loop to decode the plurality of encoded bitstreams to form a reconstructed video stream for reference picture processing, the reconstruction loop comprising:
