Abstract: A decoding device, method, and computer readable medium for partial access metadata for video-based point cloud compression data are disclosed. The decoding device for point cloud decoding includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives a compressed bitstream and metadata related to the compressed bitstream. The processor identifies, in the metadata, region information that indicates a region of a point cloud based on a user perspective; locates a track of the compressed bitstream that corresponds to the region information; identifies, in the track, objects corresponding to the region of the point cloud; and decodes for display of an object, included in the objects identified in the track, that is visible from the user perspective.

Abstract: An apparatus includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives a plurality of tracks in a compressed bitstream. The processor identifies an atlas track corresponding to a point cloud compression (PCC) component and identifies a set of first component tracks that is referenced by the atlas track and at least one second component track, each of the at least one second component track is an alternative version of a first component track of the set of first component tracks. The processor also determines which of the set of first component tracks and the at least one second component track are appropriate versions of the PCC component.

Abstract: A method and apparatus control receiving media data in a transmission system. A method of operating a receiving entity in the transmission system includes receiving packets for media data and information about a fixed delay associated with the media data. The method also includes identifying a requirement configured to guarantee that the packets for the media data are delivered to an upper layer of the receiving entity after the fixed delay, from the information about the fixed delay. The method further includes identifying a buffer size requirement for the receiving entity estimated based on the fixed delay and bitrate information associated with the media data; and delivering the packets to the upper layer of the receiving entity.

Abstract: An apparatus includes a communication interface and a processor for providing volumetric conversational service. The communication interface receives a signaling message, from a plurality of user equipment (UEs), indicating a capability of the UEs to process participant volumetric content. The processor is operably coupled to the communication interface and identifies a conference associated with the UEs for which volumetric processing is requested. The processor further provisions a plurality of media resource functions in edge application servers of edge data networks for processing the participant volumetric content from the UEs. The processor assigns one or more of the UEs to a respective media resource function of the media resource functions. Additionally, the processor instructs the participant volumetric content received from the UEs to the media resource functions. The processor instructs conference volumetric content converted by the respective media resource functions to the UEs for the conference.
