3d point cloud compression systems for delivery and access of a subset of a compressed 3d point cloud

An encoding device for point cloud encoding, comprising:

• a processor configured to:
• generate, for a three-dimensional (3D) point cloud, frames corresponding to attributes of the 3D point cloud and an occupancy map;
• encode, the frames to generate one or more bitstreams including individual tracks and media content, the individual tracks include media tracks and a timed metadata track, wherein the timed metadata track references the media tracks and the media tracks correspond respectively to the attributes;
• generate a container including the one or more bitstreams;
• and
• a communication interface operably coupled to the processor, the communication interface configured to transmit the container.
