Abstract: Super-transform coding may include identifying a plurality of sub-blocks for prediction coding a current block, determining whether to encode the current block using a super-transform, and super-prediction coding the current block. Super-prediction coding may include generating a super-prediction block for the current block by generating a prediction block for each unpartitioned sub-block of the current block, generating a super-prediction block for each partitioned sub-block of the current block by super-prediction coding the sub-block, and including the prediction blocks and super-prediction blocks for the sub-blocks in a super-prediction block for the current block. Including the prediction blocks and super-prediction blocks for the sub-blocks in a super-prediction block for the current block may include filtering at least a portion of each prediction block and each super-prediction block based on a spatially adjacent prediction block. Super-transform coding may include transforming the super-prediction block for the current block using a corresponding super-transform.

Abstract: A method for encoding a video signal using a computing device, the video signal having a plurality of frames, each frame having a plurality of blocks, and each block having a plurality of pixels. The method includes generating a residual block from an original block of a current frame and a prediction block, degrading the residual block to decrease a bit-cost for encoding the residual block, and encoding the residual block into an encoded residual block.
