    摘要: This disclosure describes techniques for simplifying depth inter mode coding in a three-dimensional (3D) video coding process, such as 3D-HEVC. The techniques include generating a motion parameter candidate list, e.g., merging candidate list, for a current depth prediction unit (PU). In some examples, the described techniques include determining that a sub-PU motion parameter inheritance (MPI) motion parameter candidate is unavailable for inclusion in the motion parameter candidate list for the current depth PU if motion parameters of a co-located texture block to a representative block of the current depth PU are unavailable. In some examples, the described techniques include deriving a sub-PU MPI candidate for inclusion in the motion parameter candidate list for the current depth PU only if a partition mode of the current depth PU is 2N×2N.

    摘要: In one example, a video decoder is configured to determine, from data associated with an open decoding refresh (ODR) picture of video data, an identifier for a previous picture of the video data, determine whether the previous picture is currently stored in a reference picture memory, and decode only data for pictures of the video data having display order values that are greater than a display order value of the ODR picture, when the previous picture is not stored in the reference picture memory. In another example, a video encoder is configured to encode an open decoding refresh (ODR) picture, determine a previously coded picture having a display order value less than a display order value of the ODR picture and having a temporal identifier value equal to zero, and signal syntax data for the ODR picture representative of an identifier of the determined previously coded picture.

    摘要: In general, this disclosure describes techniques for simplifying SDC coding of large intra-prediction blocks, such as 64×64 blocks, in a 3D video coding process, such as 3D-HEVC. In some examples, the techniques may include processing 64×64 intra-prediction blocks as four 32×32 intra-prediction blocks in intra SDC. Processing large intra-prediction blocks as multiple, smaller intra-prediction blocks in intra SDC may reduce maximum buffer size requirements in the intra SDC process.

    摘要: Techniques for reducing a number of computations in a data storage process are provided. One or more computational elements are identified in the data storage process. An ordered structure of one or more nodes is generated using the one or more computational elements. Each of the one or more nodes represents one or more computational elements. Further, a weight is assigned to each of the one or more nodes. An ordered structure of one or more reusable nodes is generated by deleting one or more nodes in accordance with the assigned weights. The ordered structure of one or more reusable nodes is utilized to reduce the number of computations in the data storage process. The data storage process converts data from a first format into a second format, and stores the data in the second format on a computer readable medium for data analysis purposes.

    摘要: During a coding process, systems, methods, and apparatus may code data representative of the positions of elements of a chain that partitions a prediction unit of video data. Some examples may include generating the data representative of the positions of elements of a chain that partitions a prediction unit of video data. Each of the positions of the elements except for a last element may be within the prediction unit. The position of the last element may be outside the prediction unit. This can indicate that the penultimate element is the last element of the chain. Some examples may code the partitions of the prediction unit based on the chain.
