1. A point cloud decoding device comprising:
a communication interface configured to:
receive a plurality of independent bitstreams containing visual volumetric coding (V3C) content, and
receive a grouping message indicating a group of assets from the plurality of independent bitstreams containing the V3C content, wherein the grouping message is a descriptor indicating a reference relationship between the assets in the group; and
a processor operably coupled to the communication interface, the processor configured to:
select, based on the grouping message, the group of assets,
identify a group identifier in the grouping message for the selected group of assets in the V3C content,
identify reference relationship information in the grouping message for each asset in the group of assets included in the V3C content based on an asset identifier for each asset in the group of assets included in an asset reference descriptor with the group identifier, and
decode at least the identified group of assets.
