Abstract: A video encoding device is configured to generate a first group of syntax elements. Each syntax element in the first group indicates whether a prediction mode of a respective prediction unit (PU) is based on an index into a list of most probable modes. A second group of syntax elements is generated that correspond to respective syntax elements in the first group. The syntax elements in the second group identify either an index into the list of most probable modes or an intra-prediction mode. The first group of syntax elements are context adaptive binary arithmetic coding (CABAC) encoded, and the second group of syntax elements are bypass encoded. A video decoder is configured to receive the entropy encoded first and second groups of syntax elements. The video decoder CABAC decodes the first group of flags and bypass decodes the second group of flags.

Abstract: As one example, techniques for decoding video data include receiving a bitstream that includes one or more pictures of a coded video sequence (CVS), decoding a first picture according to a decoding order, wherein the first picture is a random access point (RAP) picture that is not an instantaneous decoding refresh (IDR) picture, and decoding at least one other picture following the first picture according to the decoding order based on the decoded first picture. As another example, techniques for encoding video data include generating a bitstream that includes one or more pictures of a CVS, wherein a first picture according to the decoding order is a RAP picture that is not an IDR picture, and avoiding including at least one other picture, other than the first picture, that corresponds to a leading picture associated with the first picture, in the bitstream.

Abstract: A video coder may determine a motion vector of a non-adjacent block of a current picture of the video data. The non-adjacent block is non-adjacent to a current block of the current picture. Furthermore, the video coder determines, based on the motion vector of the non-adjacent block, a motion vector predictor (MVP) for the current block. The video coder may determine a motion vector of the current block. The video coder may also determine a predictive block based on the motion vector of the current block.

Abstract: A method of decoding video data including receiving (400) a bitstream that includes a sequence of bits that forms a representation of a coded picture of the video data, partitioning (402) the coded picture of the video data into a plurality of blocks using three or more different partition structures, and reconstructing (404) the plurality of blocks of the coded picture of the video data. Partitioning the coded picture of the video data may include partitioning the coded picture of the video data into the plurality of blocks using the three or more different partition structures, wherein at least three of the three or more different partition structures may be used at each depth of a tree structure that represents how a particular block of the coded picture of the video data is partitioned.
