Abstract: A method of de-blocking filtering a processed video is provided. The processed video includes a plurality of blocks and each block includes a plurality of sub-blocks. A current block of the plurality of blocks includes vertical edges and horizontal edges. The processed video further includes a set of control parameters and reconstructed pixels corresponding to the current block. A boundary strength index is estimated at the vertical edges and at the horizontal edges of the current block. The set of control parameters, the reconstructed pixels corresponding to the current block and partially filtered pixels corresponding to a set of adjacent sub-blocks are loaded. The vertical edges and the horizontal edges of the current block are filtered based on the boundary strength index and the set of control parameters such that a vertical edge of the current block is filtered before filtering at least one horizontal edge of the current block.

Abstract: A method for coding unit partitioning in a video encoder is provided that includes performing intra-prediction on each permitted coding unit (CU) in a CU hierarchy of a largest coding unit (LCU) to determine an intra-prediction coding cost for each permitted CU, storing the intra-prediction coding cost for each intra-predicted CU in memory, and performing inter-prediction, prediction mode selection, and CU partition selection on each permitted CU in the CU hierarchy to determine a CU partitioning for encoding the LCU, wherein the stored intra-prediction coding costs for the CUs are used.

Abstract: A method for motion estimation is provided that includes determining a first motion vector for a first child coding unit (CU) of a parent CU and a second motion vector for a second child CU of the parent CU, wherein the first child CU, the second child CU, and the parent CU are in a CU hierarchy, wherein the first and second child CUs are smallest size CUs in the CU hierarchy, and wherein a first motion search type is used to determine the first motion vector and the second motion vector, selecting the first and second motion vectors as candidate predictors for the parent CU, selecting a predictor for a prediction unit (PU) of the first parent CU from the candidate predictors, and refining the predictor using a second motion search type to determine a motion vector for the PU.
