摘要： This disclosure relates to techniques for reducing a cost of coding prediction information in video coding. Video blocks in a generalized P/B (GPB) frame are encoded using up to two motion vectors calculated from reference pictures in two separate reference picture lists that are identical. When one of the reference picture lists is preferred over the other reference picture list, the preferred reference picture list may be used for unidirectional prediction, by default. When a GPB frame is enabled such that the first and second reference picture lists are identical, either of the first and second reference picture lists may be used for unidirectional prediction. The techniques include coding one or more syntax elements indicating that a video block is coded using one of the unidirectional prediction mode with respect to a reference picture in a reference picture list and the bidirectional prediction mode using less than two bits.

摘要： This disclosure relates to techniques for reducing a cost of coding prediction information in video coding. Video blocks in a generalized P/B (GPB) frame are encoded using up to two motion vectors calculated from reference pictures in two separate reference picture lists that are identical. Video blocks of a GPB frame may, therefore, be encoded using a bidirectional prediction mode with a first motion vector from a reference picture in a first reference picture list and a second motion vector from the same or substantially similar reference picture in a second reference picture list. The techniques include jointly coding the first and second motion vectors for a video block of a GPB frame. The techniques include coding the first motion vector relative to a first motion predictor generated from a motion vector of a neighboring block, and coding the second motion vector relative to the first motion vector.

摘要： This disclosure describes techniques for coding video data. As one example, this disclosure describes a coded block pattern (CBP) for a coding unit (CU) of video data that indicates whether or not each of a luminance component (Y), a first chrominance component (U), and a second chrominance component (V) include at least one non-zero coefficient. According to another example, this disclosure describes a CBP that indicates whether respective blocks of a CU include at least on non-zero coefficient. The CBP described herein may be mapped to a single variable length code (VLC) code word. The VLC code word may be used by a coder to code the CU of video data.

摘要： In an example, aspects of this disclosure relate to a method of coding video data that generally includes determining prediction information for a block of video data, where the block is included in a coded unit of video data and positioned below a top row of above-neighboring blocks in the coded unit, and where the prediction information for the block is based on prediction information from one or more other blocks in the coded unit but not based on prediction information from any of the top row of blocks in the coded unit. The method also generally includes coding the block based on the determined prediction information.

摘要： In one aspect of this disclosure, template matching motion prediction is applied to B frames. In another aspect of this disclosure, template matching motion prediction as applied to video block coding may include generating a template offset, generating a weighted sum of absolute differences, selecting a number of hypotheses used to encode video blocks based on the cost associated with the number of hypotheses and signaling, with a new syntax, to a decoder, the number of hypotheses used in encoding, rejecting hypotheses if the difference in value between a hypothesis and a reference hypothesis is greater than a threshold value, and/or generating the content of a sub-block that does not have reconstructed data available by combining motion-compensated prediction and luma residuals.

摘要： In one example, this disclosure describes filtering techniques for filtering of video blocks of a video unit. The filtering techniques may select one or more different types of filtering for each video block of the video unit based on various factors such as whether the video block is inter coded or intra coded, and whether adaptive interpolations were preformed during a motion compensation process during the encoding of the video block. When adaptive interpolations were performed, the adaptive interpolations may provide a level of filtering that renders additional filtering unnecessary or undesirable in some cases.
摘要翻译：在一个示例中，本公开描述了用于过滤视频单元的视频块的滤波技术。滤波技术可以基于各种因素来选择视频单元的每个视频块的一种或多种不同类型的滤波，例如视频块是帧间编码还是帧内编码，以及在运动补偿过程期间是否执行自适应插值视频块的编码。当执行自适应插值时，自适应插值可以提供一些过滤水平，这在一些情况下不必要地或不期望地进行额外的滤波。

摘要： The techniques of this disclosure allow for wavefront parallel processing of video data with limited synchronization points. In one example, a method of decoding video data comprises synchronizing decoding of a first plurality of video block rows at a beginning of each video block row in the first plurality of video block rows, decoding the first plurality of video block rows in parallel, wherein decoding does not include any synchronization between any subsequent video block in the first plurality of video block rows, and synchronizing decoding of a second plurality of video block rows at a beginning of each video block row in the second plurality of video block rows.

摘要： In an example, aspects of this disclosure relate to a process for video coding that includes determining that a set of support for selecting a context model to code a current significant coefficient flag of a transform coefficient of a block of video data includes at least one significant coefficient flag that is not available. The process also includes, based on the determination, modifying the set of support, and calculating a context for the current significant coefficient flag using the modified set of support. The process also includes applying context-adaptive binary arithmetic coding (CABAC) to code the current significant coefficient flag based on the calculated context.

摘要： This disclosure relates to methods and apparatus for encoding and decoding video data. In an example an intra-mode for predicting a current block of video data and most probable intra-modes (MPMs) for predicting the current block of video data may be determined. An index for each of the MPMs based on an order in which the intra- mode for predicting the current block is compared to the MPMs may be determined. When one of the MPMs for predicting the current block matches the intra-mode for predicting the current block, the index of the matching MPM is signaled.
