Abstract

A video coding mechanism includes receiving a bitstream comprising a current picture including a sub-picture coded according to inter-prediction. Coded blocks contain candidate motion vectors for a current block of the sub-picture. The coded blocks include a collocated block from a different picture. A candidate list of candidate motion vectors for the current block are derived by excluding collocated motion vectors from the candidate list when the collocated motion vectors are included in the collocated block, when the collocated motion vectors point outside of the sub-picture, and when a flag is set to indicate the sub-picture is treated as a picture. A current motion vector for the current block is determined from the candidate list of candidate motion vectors. The current block is decoded based on the current motion vector. The current block is forwarded for display as part of a decoded video sequence.

Description

[0001] Related Application Cross Reference [0002] This patent application requires the application number 62 / 816,751 filed by Ye-Kui Wang et al. on March 11, 2019, and the title of the invention is "Sub-Picture Based Video Coding" Benefits and Claims of U.S. Provisional Patent Application No. 62 / 826,659 filed March 29, 2019 by Ye-Kui Wang et al., titled "Sub-Picture Based Video Coding )”, the entire contents of which are hereby incorporated by reference into this application. technical field [0003] The present invention relates generally to video coding, and in particular to coding sub-pictures in a picture in video coding. Background technique [0004] Even relatively short videos require large amounts of video data to describe, which can cause 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 transmitted over modern telecommunicati...
