Classification: CPC H | IPC H

Claim 0:
1. A system for video decoding, comprising:
a syntax decoder for parsing a coded data stream;
a prediction processor for developing hypotheses of pixel blocks;
a prediction synthesizer processor for aggregating hypotheses of pixel blocks;
a pixel block decoder for decoding pixel blocks with respect to corresponding prediction blocks;
a controller for causing the system to:
parse, by the syntax unit, a coded data stream to identify a first count of hypotheses from a syntax layer selected from a group of sequence-level, picture-level, slice-level, segment-level, and group-of-CTUs-level syntax layers, a second count greater than two of prediction lists of reference frames from a slice-level syntax layer, selected prediction lists and selected reference frames in the prediction lists for each hypothesis, and associated prediction data applied to a first pixel block, of an input frame:
generate, by the prediction processor, the first count of prediction blocks as hypotheses for the first pixel block from the prediction data, each prediction block is generated from pixel data of a corresponding selected reference frame in a corresponding selected prediction list associated with a coding hypothesis coded, wherein the first count and the second count are not the same;
aggregate, by the prediction synthesizer processor, the prediction blocks into an aggregate prediction block for the first pixel block; and
decode, by the pixel block decoder, the first pixel block with reference to the aggregate prediction block.
