The motion estimation engine has a multi-threaded structure and comprises a preprocessor for rough motion estimation of motion vectors and in-loop motion estimator for creating a coding tree unit, as well as a shared memory for interaction of the pre-processor with the in-loop motion estimator. The coding tree unit is formed by merging neighboring partitions of coding units using a list of best MV candidates.

Motion estimation engine for video encoding

Encoding methods directed to making coding decisions and estimating coding parameters including searching for optimal angular prediction in intra-prediction mode; choosing the best intra block subdivision; and providing motion estimation for tree-structured inter coding. The methods are targeted to HEVC specifications of video compression, however, may be used with other video coding standards.

Optimal angular intra prediction for block-based video coding

The video sequence encoding system with high compression efficiency is based on the H.264/AVC international video coding standard and is implementing proposed algorithms for: macroblock motion estimation; simplified rate-distortion optimization for transform size decision-making; acceleration of optimal macroblock type decision; modulation of quantization parameter with look-ahead refinement; and film-grain parameters calculation. The video encoding system comprises a motion estimation unit based on a measurement function for motion search of the matching texture block; a macroblock decision making unit; a pipeline processing module configured to accelerate complex transform; and a quantization parameter modulator configured to enhance the picture quality.
