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 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 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过滤技术。过滤技术可以基于各种因素（例如，视频块是帧间编码的还是帧内编码的，以及自适应插值是否在视频单元期间的运动补偿处理期间预先形成）来为视频单元的每个视频块选择一个或多个不同类型的滤波视频块的编码。当执行自适应插值时，自适应插值可以提供一定程度的滤波，以在某些情况下使附加滤波不必要或不合需要。

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： A video decoder is configured to obtain an index value for a current video block. The video decoder obtains a partition type for a current video block. The video decoder selects one of a plurality of defined sets of ordered candidate predictive video blocks based on the partition type of the current video block. A video decoder selects a predictive video block from a selected one of the plurality of defined sets of ordered candidate predictive video blocks based on an index value. A video decoder generates a motion vector for a current video block based on motion information of the predictive video block.

摘要： This disclosure relates to techniques for indicating that a video frame is coded as a generalized P/B (GPB) frame in order to reduce a cost of coding and constructing a second reference picture list in video coding. For a GPB frame, which has identical reference picture lists, signaling and constructing both the first and second reference picture lists may be redundant. The techniques of this disclosure may include coding syntax elements indicating that the video frame is coded as the GPB frame, and coding syntax elements indicating a number of reference pictures and reference picture list construction commands for only a first reference picture list. The techniques also include constructing the first reference picture list based on the syntax elements, and then creating the second reference picture list as a duplicate of the first reference picture list.

摘要： For a block of video data, a video encoder can signal to a video decoder a selected intra-prediction mode using a codeword that is mapped to a modified intra- prediction mode index. The video decoder can receive the codeword, determine the modified intra-prediction mode index corresponding to the codeword, determine most probable modes based on a context, map the modified intra-prediction mode index to an intra-prediction mode index by comparing the modified intra-prediction mode index to the mode indexes of the most probable modes, and determine the selected intra- prediction mode used to encode the block of video data based on the intra-prediction mode index.

摘要： For a first series of video blocks, an encoder determines two filters, a first decoding filter that is to be transmitted to a decoder and a first interim filter that is not to be transmitted to the decoder. The first interim filter is used to determine which coded units of a second series of video blocks are to be filtered. After a decision is made as to which coded units of the second series of video blocks are to be filtered, the encoder determines a second decoding filter for the second series of video blocks and transmits the second decoding filter to the decoder. In addition to determining the second decoding filter, the encoder also determines a second interim filter, which the encoder uses to determine which coded units of a third series of video blocks are to be filtered. This process may repeat for many series of video blocks.
