Abstract
Systems and methods described herein employ a high-level syntax design that supports a sub-picture extraction and reposition process. An input video may be encoded into multiple representations, each representation may be represented as a layer. A layer picture may be partitioned into multiple sub-pictures. Each sub-picture may have its own tile partitioning, resolution, color format and bit depth. Each sub-picture is encoded independently from other sub-pictures of the same layer, but it may be inter-predicted from the corresponding sub-pictures from its dependent layers. Each sub-picture may refer to a sub-picture parameter set where the sub-picture properties such as resolution and coordinate is signaled. Each sub-picture parameter set may refer to a PPS where the resolution of the entire picture is signaled.
