Abstract:
Media content may be adaptively (for example, selectively or partially) streamed based on temporal levels. The temporal levels may be indicated in a media content manifest (for example, a media presentation description (MPD)). For example, media samples for geometry-based point cloud compression (G-PCC) media content may be divided into temporal levels associated with temporal level identifiers. An MPD may indicate one or more adaptation sets associated with G-PCC media content. An adaptation set may be selected from multiple adaptation sets, A representation set may be determined from the selected adaptation set. An indication of a G-PCC descriptor associated with a representation of the representation set may be obtained from the MPD. Temporal levels present in the representation may be identified using the G-PCC descriptor, which may include a set of temporal level identifiers, The representation may be selected based on the G-PCC descriptor.
