Embodiment Construction

[0049] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents Modified within the full range of .

[0050] As used herein, resolution describes the number of pixels in a video file. That is, resolution is the width and height of the projected image measured in pixels. For example, a video might have a resolution of 1280 (horizontal pixels) by 720 (vertical pixels). This is often shortened to 1280×720, or 720p for short. Bi-directional optical flow (bi-directional optical flow, BDOF), decoder-sid...

Abstract

A method of decoding includes receiving the coded video bitstream, the coded video bitstream containing reference picture lists; obtaining reference pictures for a current picture from the reference picture lists; setting a motion vector refinement flag to a first value to enable motion vector refinement for a current block of the current picture when the reference pictures are in a same layer as the current picture; setting the motion vector refinement flag to a second value to disable the motion vector refinement for the current block of the current picture when the reference pictures are in a different layer than the current picture; and refining a motion vector corresponding to the current block when the motion vector refinement flag is set to the first value.

Description

[0001] Related Application Cross Reference [0002] This patent application requires Chen Jianle and others to submit on June 4, 2019, and the application number is 62 / 857,152. The title of the invention is "Inter Coding in Video Coding with the Support of Multiple Layers), which is incorporated herein by reference. technical field [0003] This disclosure generally describes techniques for supporting motion vector correction in video coding. More specifically, the invention supports disabling motion vector correction when the reference picture is from a different layer than that of the current picture. Background technique [0004] Even relatively short videos require large amounts of video data to describe, which can create difficulties when the data is to be streamed or otherwise transmitted over communication networks with limited bandwidth capacity. Therefore, video data is usually compressed before being sent over modern telecommunications networks. Since memory res...
