摘要： An asymmetric frame of a coded video bitstream may include a full resolution picture of a left view and a reduced resolution picture of a right view, where the left and right views form a stereo view pair for three-dimensional video playback. In one example, an apparatus includes a video encoder configured to receive a first picture of a first view of a scene having a first resolution, receive a second picture of a second view of the scene having a reduced resolution relative to the first resolution, form an asymmetric frame comprising the first picture and the second picture, and encode the asymmetric frame. In this manner, decoders of varying capabilities may receive the same bitstream, and the bitstream may consume less bandwidth than one or more bitstreams having full resolution pictures of a stereo view pair. The bitstream may have better quality than a bitstream having subsampled pictures.

摘要： A demultiplexer may assemble view components of sub-bitstreams. In one example, an apparatus comprises a demultiplexer that produces a multiview video coding (MVC) standard compliant bitstream from a received bitstream comprising a primary sub-bitstream and an embedded sub-bitstream. To produce the MVC standard compliant bitstream, the demultiplexer determines whether a view component of the primary sub-bitstream has a view order index that is greater than a view order index of a view component of the embedded sub-bitstream, and to add the view component from the sub-bitstream for which the view order index is lower to the produced bitstream. The received bitstream may comprise delimiter network abstraction layer (NAL) units between each view component to differentiate the view components. The apparatus may further comprise a video decoder to decode the bitstream produced by the demultiplexer.

摘要： This disclosure describes techniques for encoding a two-dimensional (2D) video sequence of video frames along with three-dimensional (3D) conversion information comprising a set of parameters that can be applied to each of the video frames of the 2D sequence to generate 3D video data. The set of parameters may comprise a relatively small amount of data that can be applied to each of the original video frames of the 2D sequence to generate secondary views of each of the original video frames. The original video frames and the secondary views may collectively define a stereoscopic 3D video sequence. The 2D sequence and the set of parameters may comprise significantly less data than would otherwise be needed to communicate a 3D sequence. This disclosure also describes some exemplary syntax that may be used to encode the set of parameters in an effective and efficient manner.

摘要： A video coding device includes a memory configured to store video data, and processing circuitry in communication with the memory. The processing circuitry is configured to determine that a current block of the video data stored to the memory is to be coded according to a merge mode, and to determine a temporal candidate associated with a merge candidate list for the current block in accordance with the merge mode. The processing circuitry is further configured to determine a pool of spatial candidates associated with the merge candidate list, based on each spatial candidate of the pool having a same reference picture as the temporal candidate, and to set a local illumination compensation (LIC) flag value for the temporal candidate based on respective LIC flag values of one or more spatial candidates of the pool.

摘要： The techniques of this disclosure apply to loop filtering across slice or tile boundaries in a video coding process. In one example, a method for performing loop filtering in a video coding process includes determining that pixels corresponding to filter coefficients of a filter mask for a loop filter are across a slice or tile boundary, removing filter coefficients corresponding to the pixels across the slice or tile boundary from the filter mask, renormalizing the filter mask without the removed filter coefficients, performing loop filtering using the renormalized filter mask

摘要： This disclosure proposes techniques for transform partitioning in an intra-prediction video coding process. In one example, for a given intra-predicted block, a reduced number of transform unit partition options is allowed, based on certain conditions. In another example, transform units are decoupled from prediction units for intra-predicted block. For a given prediction unit, transforms of different sizes and shapes from the prediction unit may be applied. In another example, a reduced number of intra-prediction modes are allowed for a prediction unit having a non-square shape.

摘要： A unified candidate block set for both adaptive motion vector prediction (AMVP) mode and merge mode for use in inter-prediction is proposed. In general, the same candidate block set is used regardless of which motion vector prediction mode (e.g., merge mode or AMVP mode) is used. In other examples of this disclosure, one candidate block in a set of candidate blocks is designated as an additional candidate block. The additional candidate block is used if one of the other candidate blocks is unavailable. Also, the disclosure proposes a checking pattern where the left candidate block is checked before the below left candidate block. Also, the above candidate block is checked before the right above candidate block.

摘要： In an example, aspects of this disclosure relate to a method of coding video data that includes determining context information for a block of video data, where the block is included within a coded unit of video data, where the block is below a top row of blocks in the coded unit, and where the context information does not include information from an above-neighboring block in the coded unit. That method also includes entropy coding data of the block using the determined context information.
