Abstract
An apparatus to facilitate real-time playback of point cloud sequence data is disclosed. The apparatus comprises one or more processors to receive point cloud data of a captured scene, decompose the point cloud data into a plurality of point cloud patches, wherein each point cloud patch is associated with an object in the scene and includes contextual information regarding the point cloud patch, encode each of the point cloud patches via a deep-learning based algorithm to generate encoded point cloud patches, receive a viewpoint selection from a client, assign a priority to data chunks within each encoded point cloud patch based on the viewpoint selection and the contextual information and transmit the data chunks to the client based on the assigned priority.
