[0002] This application claims the benefit of US Provisional Application 60 / 823,567, filed August 25, 2006, which is hereby incorporated by reference in its entirety. technical field

[0003] The present invention relates generally to video encoding and decoding, and more particularly to methods and apparatus for reduced resolution partitioning. Background technique

[0004] Prior art video encoders employ adaptive block partitioning to optimally classify visual data for efficient encoding. To achieve this, most coding algorithms divide each frame on a uniform grid of given dimensions (macroblocks), and then based on the video data, these algorithms further divide each block into smaller divisions to best fit the video data. An inherent limitation of this approach is that, in existing standards such as the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Moving Picture Exper...
