Abstract
The techniques described herein relate to methods, apparatus, and computer readable media configured to encode or decode a region of interest associated with video data. A spherical region structure is associated with the video data that specifies the region of interest on a sphere, the spherical region structure including a reference point of the region of interest on the sphere, and data indicative of a set of side points, comprising a side point for each side of the region of interest on the sphere. The region of interest in the video data is determined based on the reference point and the set of side points. The video data can be composite video data. The spherical region structure, and/or metadata based on the spherical region structure, can be implicitly or explicitly associated with the video data.
