Title:
VIDEO ENCODING OR DECODING METHODS AND APPARATUSES RELATED TO HIGH-LEVEL INFORMATION SIGNALING
Document Type and Number:
WIPO Patent Application WO/2021/136375
Kind Code:
A1
Abstract:
Video processing methods and apparatuses for processing video pictures referring to a high-level syntax set include receiving input data, determining a first syntax element indicating whether reference picture resampling is disabled or constrained, determining a second syntax element indicating whether subpicture partitioning is disabled or constrained, and encoding or decoding the video pictures. The first and second syntax elements are restricted to disable or constrain subpicture partitioning when reference picture resampling is enabled or disable or constrain reference picture resampling when subpicture partitioning is enabled. The first syntax element and the second syntax element are syntax elements signaled in the high level syntax set.
