Abstract

A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising one or more sub-pictures partitioned from a picture and a sub-picture level indicator indicating resource requirements for decoding a current sub-picture. The bitstream is parsed to obtain the sub-picture level indicator and the current sub-picture. Resources are allocated to decode the current sub-picture based on the sub-picture level indicator. The current sub-picture is decoded to create a video sequence by employing the allocated resources. The video sequence is forwarded for display.

Description

[0001] Related Applications Cross Application [0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 62 / 790,207, filed on January 9, 2019, by Wang Yekui et al., entitled "Sub-Pictures in Video Coding", the entire The contents are incorporated herein by reference. technical field [0003] The present invention relates generally to video coding, and more particularly to sub-picture management in video coding. Background technique [0004] Large amounts of video data need to be described even in the case of short videos, which can cause difficulties when the data is to be sent 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 resources may be limited, the size of the video may also be an issue when storing the video on a storage device. Video compression devices typically use software a...
