Abstract: Systems and methods for performing motion vector prediction for video coding are disclosed. A motion vector predictor is determined based at least in part on motion information associated with a selected motion vector predictor origin and offset values corresponding to a selected sampling point. The sampling point is specified according to a set of direction and distance on a sampling map for the motion vector predictor origin.

Abstract: A hardware encoder has a bit estimation block to compute an estimated bit size for a Coding Tree Unit (CTU). A CTU bit size limit manager selects quantization parameters for use in quantization. The quantization parameters are selected based upon the estimated bit size to insure that the CTU in coded form will not exceed a CTU bit size limit.

Abstract: A hardware video encoder includes a first inter-picture prediction search processor to perform at least one coarse search at a designated block size. The at least one coarse search utilizes a down-sampled version of an image to determine motion vectors. A second inter-picture prediction search processor performs motion vector refinement searches on pixels of the image for multiple block sizes. Searches of at least one block size utilize the motion vectors. A third inter-picture prediction search processor performs fractional pixel motion vector refinement searches on interpolated values of the pixels of the image for multiple block sizes in parallel.

Abstract: A hardware video encoder includes an intra search block operating on a source picture to produce pairs of intra prediction mode indices and rate-distortion values for different block sizes. The pairs of intra prediction mode indices and rate-distortion values for the different block sizes are computed in parallel based upon the source picture. An inter search block produces pairs of motion vectors and rate-distortion values for different block sizes. The pairs of motion vectors and rate-distortion values for the different block sizes are computed in parallel.
