摘要： Filtering is applied at an encoder, and filter information describing a set of filters is encoded in the bitstream to enable a decoder to identify the filtering that was applied at the encoder. The decoder receives encoded video data that includes the filter information, decodes the video data, and applies filtering based on the filtering information. The decoder applies the same filtering that was applied at the encoder. To potentially reduce the number of bits needed to reconstruct the set of filters and other filter information as well as to potentially improve decoder performance, filter description syntax describing the set of filters can be included in the bitstream. The filter description syntax may identify a number of filters in a set of filters, a maximum number of filters in a set of filters, and/or identify a shape of filters in a set of filters.

摘要： An interim filter determined for a previous series of video blocks can be applied to a current series of video blocks to determine an interim filter map for the current series of video blocks. Based on the interim filter map, a decoding filter can be determined. By applying the decoding filter to the current series of video blocks, a decoding filtering map can be determined. Based on CUs identified as having filtering off by the decoding filtering map, an interim filter for the current series of video blocks can be determined. The decoding filter and decoding filtering map can be transmitted to a decoder, while the interim filter and interim filter map may not be transmitted to a decoder. The interim filter for the current series of video blocks can be used to generate an interim filter map for a next series of video blocks.

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.

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 encoder may encode video data by adaptively selecting between one-eighth-pixel and one-quarter-pixel precision motion vectors, and signal the selected precision. In one example, an apparatus includes a video encoder to encode a block of video data using a one-eighth-pixel precision motion vector when use of the one-eighth-pixel precision motion vector is determined to be preferable for the block over a one-quarter-pixel precision motion vector, and to generate a signal value indicative of the use of the one-eighth-pixel precision motion vector for the block, and an output interface to output the encoded block and the signal value. A video decoder may be configured to receive the signal value and the encoded block, analyze the signal value to determine whether the block was encoded using one-eighth-pixel precision or one-quarter-pixel precision, and decode the block based on the determination.

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.
