Abstract
An encoding device, a decoding device and a method for point cloud encoding is provided. The method includes generating, for a 3D point cloud, frames corresponding to attributes of the 3D point cloud and an occupancy map. The method also includes encoding, the frames to generate one or more bitstreams. The one or more bitstreams include individual tracks and media content. The individual tracks include media tracks and a timed metadata track. The timed metadata track references the media tracks and the media tracks correspond respectively to the attributes. The method also includes generating a container including the one or more bitstreams transmitting the container.
