Claim:
1. A video decoding method, comprising: receiving a video block; determining a prediction mode for the video block; determining a subsampled sub-block of the video block based on the prediction mode for the video block, wherein the video block comprises parameters that represent the subsampled sub-block of the video block and one or more remaining subsampled blocks of the video block, wherein the subsampled sub-block comprises pixels from two or more rows and two or more columns of the video block; generating a predicted subsampled sub-block based on the prediction mode; generating a reconstructed subsampled sub-block based on the predicted subsampled sub-block and the parameters; and generating predicted subsampled blocks of the one or more remaining subsampled blocks based on the reconstructed subsampled sub-block and the prediction mode; generating one or more reconstructed remaining subsampled blocks based on the predicted subsampled blocks of the one or more remaining subsampled blocks and the parameters; and generating a reconstructed video block based on the reconstructed subsampled sub-block and the one or more reconstructed remaining subsampled blocks.
