1. A method of conveying decoding information for a point cloud (PC) bitstream of coded PC sequences, the method comprising:
mapping a metadata component bitstream of the PC bitstream into a first restricted video track of an International Organization for Standardization/International Electrotechnical Commission Base Media File Format (ISOBMFF), wherein the first restricted video track of the ISOBMFF comprises one or more access units of the metadata component bitstream;
mapping a geometry sub-bitstream of the PC bitstream into a second restricted video track of the ISOBMFF, wherein the second restricted video track of the ISOBMFF comprises one or more access units of the geometry sub-bitstream;
mapping an occupancy sub-bitstream of the PC bitstream into a third restricted video track of the ISOBMFF, wherein the third restricted video track of the ISOBMFF comprises one or more access units of the occupancy sub-bitstream;
adding, to the first restricted video track, indications of links between the metadata component bitstream and the geometry sub-bitstream and between the metadata component bitstream and the occupancy sub-bitstream using a track reference tool; and
generating an ISOBMFF container to transmit the metadata component bitstream mapping, the geometry sub-bitstream mapping, and the occupancy sub-bitstream mapping for the PC bitstream.
