符号化ビデオ・ストリームにおけるサブ画像のビットストリーム抽出のための技術

Japanese Patent JP7447147

B2

A method, computer program, and computer system are provided for video coding. Video data having one or more subpictures is received. Resampling parameters and spatial scalability parameters corresponding to the subpictures are extracted. The resampling and spatial scalability parameters correspond to one or more flags signaled in a parameter set associated with the video data The video data is decoded based on the extracted resampling and spatial scalability parameters.
