Abstract
The techniques described herein relate to methods, apparatus, and computer readable media configured to encode and/or decode video data. Immersive media data includes a first patch track comprising first encoded immersive media data that corresponds to a first spatial portion of immersive media content, a second patch track comprising second encoded immersive media data that corresponds to a second spatial portion of the immersive media content that is different than the first spatial portion, an elementary data track comprising first immersive media elementary data, wherein the first patch track and/or the second patch track reference the elementary data track, and grouping data that specifies a spatial relationship between the first patch track and the second patch track in the immersive media content. An encoding and/or decoding operation is performed based on the first patch track, the second patch track, the elementary data track and the grouping data to generate decoded immersive media data.
