Abstract: An apparatus includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives a plurality of tracks in a compressed bitstream. The processor identifies an atlas track corresponding to a point cloud compression (PCC) component and identifies a set of first component tracks that is referenced by the atlas track and at least one second component track, each of the at least one second component track is an alternative version of a first component track of the set of first component tracks. The processor also determines which of the set of first component tracks and the at least one second component track are appropriate versions of the PCC component. The processor further decodes the appropriate version of the PCC component from among the set of first component tracks and the at least one second component track.

Abstract: Methods and apparatuses for extracting and merging bitstreams. An apparatus includes a communication interface and a processor. The communication interface receives a plurality of bitstreams for a video and a processor. The processor identifies information about independently coded regions in each of the plurality of bitstreams, receives a region of interest in the video, selects, based on the identified information, one or more independently coded regions in each of the plurality of bitstreams that corresponds to the region of interest, and extracts the selected independently coded regions to generate one or more extracted bitstreams.

Abstract: A user equipment (UE) for processing 360° video includes a memory and a processor. The memory receives video data and metadata for processing the video data where the video includes a plurality of regions. The processor determines when the metadata includes an indication that at least one region from the plurality of regions includes a guard margin along at least one boundary of the at least one region. When the indication indicates that the at least one region includes the guard margin, the processor process the video data based on the received metadata.
