Abstract
Video coding and decoding techniques, including history-based motion vector prediction with default parameters, are described. One example video processing method includes resetting, for a conversion between a video unit of a video and a bitstream of the video, a history-based motion vector prediction (HMVP) table of size N by adding K HMVP motion candidates to the HMVP table, where the K HMVP motion candidates have default values, where N and K are positive integers, and where K≤N; and performing the conversion between the video unit and the bitstream using the HMVP table resulting from the resetting.
Claims20
A method of video processing, comprising:
- resetting, for a conversion between a video unit of a video and a bitstream of the video, a history-based motion vector prediction (HMVP) table of size N by adding K HMVP motion candidates to the HMVP table, wherein the K HMVP motion candidates have default values, wherein N and K are positive integers, and wherein K≤N;
- and
- performing the conversion between the video unit and the bitstream using the HMVP table that results from the resetting.
An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- reset, for a conversion between a video unit of a video and a bitstream of the video, a history-based motion vector prediction (HMVP) table of size N by adding K HMVP motion candidates to the HMVP table, wherein the K HMVP motion candidates have default values, wherein N and K are positive integers, and wherein K≤N;
- and
- perform the conversion between the video unit and the bitstream using the HMVP table that results from the resetting.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
- resetting a history-based motion vector prediction (HMVP) table of size N by adding K HMVP motion candidates to the HMVP table, wherein the K HMVP motion candidates have default values, wherein N and K are positive integers, and wherein K≤N;
- and
- generating the bitstream using the HMVP table that results from the resetting.
