Abstract: A client device adaptively streams a 360-degree video. A first segment is displayed based on a first viewing direction at a first time, where the first viewing direction is associated with a first viewport. The client requests a first base buffer segment based on the first viewport. The first base buffer segment has a presentation time after the first segment. At a second time, the viewing direction changes to a second viewing direction associated with a second viewport. The client requests, prior to the presentation time, a first viewport buffer segment based on the second viewport, with the same presentation time. The client device displays a second segment at the presentation time, wherein the second segment is either the first viewport buffer segment or the first base buffer segment. The client provides reports on viewport switching latency and on the most-requested segments.

Abstract: Methods, apparatus, systems, architectures and interfaces for encoding and/or decoding point cloud bitstreams including coded point cloud sequences are provided. Included among such methods, apparatuses, systems, architectures, and interfaces is an apparatus that may include a processor and memory. A method may include any of: mapping components of the point cloud bitstream into tracks; generating information identifying any of geometry streams or texture streams according to the mapping of the components; generating information associated with layers corresponding to respective geometry component streams; and generating information indicating operation points associated with the point cloud bitstream.

Abstract: Systems, methods, and instrumentalities are disclosed herein that relate to video-based point cloud streams in one or more ISO Base Media File Format (ISOBMFF) container files. A container format for point cloud data is provided and the container format indicates at least a relationship between a 3D region of the point cloud and one or more video-based point cloud compression (V-PCC) tracks. The V-PCC tracks may be grouped together and linked to the 3D region to allow spatial access to the 3D region.
