Abstract:
Coding efficiency may be improved by subdividing a block into smaller sub-blocks for prediction. A first rate distortion value of a block optionally partitioned into smaller prediction sub-blocks of a first size is calculated using respective inter prediction modes and transforms of the first size. The residuals are used to encode the block using a transform of a second size smaller than the first size, generating a second rate distortion value. The values are compared to determine whether coding efficiency gains may result from inter predicting the smaller, second size sub-blocks. If so, the block is encoded by generating prediction residuals for the second size sub-blocks, and neighboring sub-blocks are grouped, where possible, based on common motion information. Each resulting composite residual block is transformed by a transform of the same size to generate another rate distortion value. The encoded block with the lowest rate distortion value is used.

Claim (Index 3):
The method of  claim 1 , wherein the block is a first block, the method further comprising:\n encoding a second block a first time to generate a first rate distortion value for the second block by encoding at least one sub-block of the second block having the first size using a respective inter prediction mode and the transform having the first size; encoding the second block a second time, after encoding the second block the first time, to generate a second rate distortion value by encoding the at least one sub-block of the second block having the first size using the respective inter prediction mode and the transform having the second size smaller than the first size; encoding the second block at least a third time, after encoding the second block the second time, to generate a respective rate distortion value by encoding a plurality of sub-blocks of the second block having at least a third size greater than the first size; and selecting one of the encoded second blocks as an output encoded block depending upon which has a lowest rate distortion error.
