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： 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： 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： 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.
