Abstract: A user equipment is provided for providing content. The user equipment comprising at least one memory and at least one processing device. The at least one process is configured to receive a data stream over a network, the data stream comprising un-segmented media data for the content. The at least one process is also configured to identify segment boundaries in the un-segmented media data to identify segments and determine a segment number for each of the identified segments from a media presentation description (MPD) based on the segment boundaries. The at least one process is also configured to retrieve a uniform resource locator (URL) associated with each of a plurality of dynamic adaptive streaming over hypertext transfer protocol (DASH) segments based on the segment number for each of the plurality of DASH segments and provide the URL associated with each of the plurality of DASH segments to a client player.

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 comprises a communication interface and a processor operably coupled to the communication interface. The communication interface is configured to receive a compressed bitstream including association information between scene objects and submeshes. The processor is configured to determine an index of a scene object, decode the association information between scene objects and submeshes, determine an identifier of a submesh based on the association information and the index of the scene object, and reconstruct the submesh based on the identifier.

Abstract: An apparatus includes a communication interface and a processor operably coupled to the communication interface. The processor is configured to receive, via the communication interface, a bitstream including complexity metrics (CM) metadata. The processor is also configured to extract information in the CM metadata from the bitstream, wherein the information includes a direct indication of a number of coding units (CUs) in the bitstream that have non-zero transform coefficients, for each CU size of a plurality of CU sizes. The processor is further configured to predict a decoding complexity of the bitstream based on information in the CM metadata.

Abstract: A decoding device includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives at least a portion of a broadcast stream including media data, which includes media samples. The processor identifies information elements containing DRM processing information in the broadcast stream. Each information element is associated with a respective one media sample of the media data. For each information element, the processor also identifies the one media sample that is associated with the information element. The processor further identifies, based on the information element, the DRM processing information for the one media sample. In addition, the processor decodes the one media sample based on the DRM processing information.
