Abstract: A UE includes a communication unit, a display, at least one sensor, and a processor. The communication unit receives video from a server and the display renders a portion of the video. The sensor determines a pitch and a yaw of the portion of the video and a processor generates metadata that includes the pitch and the yaw.

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: A method of operating a sending entity in the transmission system includes identifying a fixed delay associated with a transmission of media data in the transmission system and sending, to a receiving entity, information about the fixed delay as a requirement being configured to guarantee that packets for the media data, received by the receiving entity, are delivered to an upper layer of the receiving entity after the fixed delay. A method of operating a receiving entity in the transmission system includes receiving media data and information about a fixed delay associated with the media data and identifying a requirement, being configured to guarantee that packets for the media data are delivered to an upper layer after the fixed delay, from the information about the fixed delay.

Abstract: A decoding device, an encoding device and a method for point cloud decoding is disclosed. The method includes decoding the compressed bitstream into a first set and second set of 2-D frames. The first set of 2-D frames include first set of regular patches representing geometry of a 3-D point cloud and the second set of 2-D frames include first set of regular patches representing texture of the 3-D point cloud. The method includes identifying in the first set of 2-D frames, a missed points patch representing geometry of points of the 3-D point cloud not included in the regular patches, and in the second set of 2-D frames a missed points patch that represents texture of the points of the 3-D point cloud not included in the regular patches. The method also includes generating, using the set of 2-D frames, the 3-D point cloud using the missed points patches.

Abstract: A video player for generating omni media texture mapping metadata is provided. The video player includes a memory and a processor connected to the memory. The processor is configured to receive, from a video processor, a signal indicating a shape of a geometric frame for a video and an area of interest on a planar frame. The processor is also configured to map the area of interest on the planar frame to a region of interest on the geometric frame based on the shape of the geometric frame. The processor is further configured to generate the geometric frame with the region of interest.

Abstract: A method and an apparatus for converting a moving picture expert group (MPEG) media transport (MMT) stream into a MPEG-2 transport stream (TS). The method including applying restrictions to MMTP packets for the MMTP stream. The method also includes converting a presentation time and decoding time from a coordinated universal time (UTC) based absolute time to a program clock reference time (PCR) based value. The method further includes, when converting the MMTP stream to the MPEG-2 TS, constructing the MMTP stream based on MPEG-2 TS rules without adding or removing data by using a hypothetical receiver buffer model (HRBM). Additionally, the method includes determining values of MPEG-2 TS packet fields of a TS packet layer, an adaptation field and Packetized Elementary Stream (PES) packets from values of the MMTP packets.

Abstract: A method and apparatus for randomly accessing high efficiency video coding (HEVC) bitstream for moving picture experts group (MPEG) media transport (MMT). The method includes receiving a plurality of packets for a video in decoding order. The method also includes determining a packet marked to begin processing the video, removing packets of leading pictures in the marked packet from the memory, and processing the packets remaining in the memory.
