METHODS AND APPARATUS FOR SIGNALING SPATIAL RELATIONSHIPS FOR POINT CLOUD MULTIMEDIA DATA TRACKS

摘要

The techniques described herein relate to methods, apparatus, and computer readable media configured to encode and/or decode video data. Point cloud video data includes a plurality of tracks. first metadata of a first track of the plurality of tracks, the first metadata specifying a first source region of a plurality of source regions of the point cloud video data, wherein each source region corresponds to a different spatial portion of the point cloud video data. The first metadata specifies a sub-region of the first track in the first source region comprising data indicative of a spatial position of video data of the first track in the first source region. Point cloud media is generated, based on the first metadata, for the sub-region of the first source region using the video data of the first track.
