摘要： A video coder determines a candidate for inclusion in a candidate list for a current prediction unit (PU). The candidate is based on motion parameters of a plurality of sub-PUs of the current PU. If a reference block corresponding to a sub-PU is not coded using motion compensated prediction, the video coder sets the motion parameters of the sub-PU to default motion parameters. For each respective sub-PU from the plurality of sub-PUs, if a reference block for the respective sub-PU is not coded using motion compensated prediction, the motion parameters of the respective sub-PU are not set in response to a subsequent determination that a reference block for any later sub-PU in an order is coded using motion compensated prediction.

摘要： The latest High Efficiency Video Coding (HEVC) standard achieves significant compression efficiency improvement over the H.264 standard, at a much higher cost of computational complexity. A framework for software-based H.264 to HEVC transcoding on multicore processors and distributed systems is provided. By utilizing information extracted from the input H.264 bitstream, the transcoding process can be accelerated at a high ratio with modest visual quality loss. Wavefront Parallel Processing (WPP) and SIMD acceleration are also implemented to improve the trans coding efficiency on multi-core processors with SIMD instruction set extensions. Based on the HEVC HM 12.0 reference software and using standard HEVC test bitstreams, the proposed transcoder can achieve around 120x speed up over decoding and re- encoding based on ffmpeg and the HM software without significant R-D performance loss.

摘要： A disparity vector generation section generates disparity vectors indicating a part of a disparity between a first layer image and a second layer image different from the first layer image and different part of the disparity based on a code indicating the part of the disparity. A predicted image generation section reads a reference image of a region indicated by the disparity vector generated by the disparity vector generation section from a reference image storage section that stores the reference image and generates a predicted image based on the read reference image.

摘要： A method and apparatus for three-dimensional and multi-view video coding are disclosed, where the motion vector (MV) or disparity vector (DV) candidate list construction process for a block depends on whether the target reference picture corresponds to an inter-view reference picture or whether the inter-view candidate refers to an inter-view reference picture. In one embodiment, an MV or DV candidate list for a block coded in Merge mode is constructed, and an inter-view candidate in the MV or DV candidate list is set lower than the first candidate position if the inter-view candidate refers to an inter-view reference picture. In another embodiment, an MV or DV candidate list for a block coded in advanced motion vector prediction mode is constructed, and an inter-view candidate is set lower than the first candidate position if the inter-view candidate refers to an inter-view reference picture.
