Abstract
The maximum block size associated with predicting blocks in frames of video data is adaptively determined. The distribution of optimal prediction block sizes associated with one or more existing frames of video data is identified, and a candidate maximum prediction block size is identified (e.g., based on the most prevalent prediction block size in the distribution of prediction block sizes). A variable associated with the level of use of blocks having the candidate maximum prediction block size is compared with thresholds associated with the current maximum prediction block size. If the level of use is between upper and lower thresholds, the next maximum prediction block size set equal to the current maximum prediction block size. If the level of use is greater or less than the upper or lower thresholds, respectively, the next maximum block size is set to the current maximum prediction block size plus or minus one block size and bounded by the largest and smallest prediction block sizes of the encoder.
