A video coding architecture is described that is based on nested and pre-configurable quadtree structures for flexible and signal-adaptive picture partitioning. The primary goal of this partitioning concept is to provide a high degree of adaptability for both temporal and spatial prediction as well as for the purpose of space-frequency representation of prediction residuals. At the same time, a leaf merging mechanism is included in order to prevent excessive partitioning of a picture into
more » ... tion blocks and to reduce the amount of bits for signaling the prediction signal. For fractional-sample motion-compensated prediction, a fixed-point implementation of the Maximal-Order-Minimum-Support (MOMS) algorithm is presented that uses a combination of IIR and FIR filtering. Entropy coding utilizes the concept of probability interval partitioning entropy (PIPE) codes that offers new ways for parallelization and enhanced throughput. The presented video coding scheme was submitted to a joint Call for Proposals of ITU-T Visual Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG) and was ranked among the five best performing proposals, both in terms of subjective and objective quality. Index Terms-High efficiency video coding, HEVC.
