    Abstract: Quantization parameter (QP) update classification techniques for display stream compression (DSC) are disclosed. In one aspect, a method for determining a quantization parameter (QP) value includes determining whether a current block includes a transition from a flat region to a complex region or is a flat block and determining whether a previous block includes a transition from a flat region to a complex region or is a flat block. The method may also include selecting a default technique or an alternative technique for calculating a QP adjustment value for the current block based on whether the previous and current blocks include a transition from a flat region to a complex region or are flat blocks.

    Abstract: An example video coding device is configured to determine a depth value associated with a block of video data included in a dependent depth view, based on one or more neighboring pixels positioned adjacent to the block of video data in the dependent depth view, and generate a disparity vector associated with the block of video data, based at least in part on the determined depth value associated with the block of video data. The video coding device may further be configured to use the disparity vector to generate an inter-view disparity motion vector candidate (IDMVC), generate an inter-view predicted motion vector candidate (IPMVC) associated with the block of video data based on a corresponding block of video data in a base view, and determine whether to add any of the IDMVC and the IPMVC to a merge candidate list associated with the block of video data.

    Abstract: A video coder can be configured to perform texture first coding for a first texture view, a first depth view, a second texture view, and a second depth view; for a macroblock of the second texture view, locate a depth block of the first depth view that corresponds to the macroblock; based on at least one depth value of the depth block, derive a disparity vector for the macroblock; code a first sub-block of the macroblock based on the derived disparity vector; and, code a second sub-block of the macroblock based on the derived disparity vector.

    Abstract: A method and system for encoding video data in a constant bit rate video encoder. A video encoder may determine a coding mode for encoding a block of video data from among one or more coding modes based on a minimum syntax element size and a maximum syntax element size, wherein the minimum syntax element size is greater than 1 bit, encode the block of video data in a plurality of substreams according to the determined coding mode to create a plurality of encoded substreams of video data, store the plurality of encoded substreams of video data in respective balance FIFO buffers, and multiplex the plurality of encoded substreams in a bitstream for transmitting to a decoder.
