    摘要： Deriving a motion vector of a current block, in a current frame, including: generating a motion vector predictor candidate list including a set of first motion vectors and a second motion vector, wherein a first motion vector of the set belongs to a block adjacent to the current block in the current frame, and the second motion vector is a temporal motion vector of a pixel at a modified position (x′, y′) in a previous frame, the modified position (x′, y′) being derived by modifying a top-left position (x, y) of the current block. The method also includes deriving the modified position (x′, y′) using arithmetic shift operations; setting the second motion vector equal to a motion vector at the modified position (x′, y′) of the pixel in the previous frame; and deriving the motion vector of the current block using a motion vector predictor and a difference motion vector.

    摘要： A system utilizes a high throughput coding mode for CABAC in HEVC. The system may include an electronic device configured to obtain a bit stream; determine whether to decode level information of the sub-block of a block from the bit stream by using a first or a second decoding based on a characteristic of the sub-block; if the characteristic of the sub-block satisfies a predetermined condition, decoding level information of the sub-block from the bit stream by using the first decoding, and if the characteristic of the sub-block does not satisfy the predetermined condition, decoding level information of the sub-block from the bit stream by using the second decoding that is different from the first decoding.

    摘要： An image decoder includes a base layer to decode at least a portion of an encoded video stream into a first image having a first image format. The image decoder can generate a color space prediction by scaling a color space of the first image from the first image format into a color space corresponding to a second image format. The image decoder includes an enhancement layer to decode the encoded video stream to generate a second image in the second image format based, at least in part, on the color space prediction.

    摘要： A method for decoding video includes receiving a frame of the video that includes at least one slice and at least one tile. Each of the at least one slice and the at least one tile are not all aligned with one another. Each of the at least one slice is characterized that it is decoded independently of the other the at least one slice. Each of the at least one tile is characterized that it is a rectangular region of the frame and having coding units for the decoding arranged in a raster scan order. The at least one tile of the frame are collectively arranged in a raster scan order of the frame.

    摘要： Aspects of the present invention relate to systems and methods for intra prediction. According to one aspect of the present invention, a macroblock may be partitioned into two, or more, sets of blocks. The pixel values for a block within a first set of blocks may be predicted using reconstructed values from only neighboring macroblocks. The pixel values for a block within another set of blocks may be subsequently predicted using reconstructed values from blocks in previously reconstructed sets of blocks and/or reconstructed values from neighboring macroblocks. The pixel values for blocks within a set of blocks may be predicted in parallel.
