    Abstract: A point cloud encoding device includes a point cloud encoding device includes a communication interface and a processor operably coupled to the communication interface. The communication interface is configured to receive a plurality of independent bitstreams. The communication interface is also configured to receive a grouping message indicating a group of assets from the plurality of independent bitstreams containing visual volumetric coding (V3C) content. The processor is configured to select the group of assets based on the grouping message. The processor is configured to decode at least the selected group of assets.

    Abstract: Methods and apparatuses for managing received data by a client device and indicating data removal management by a server. A method for managing received data by a client device includes receiving a message including information about a number of modes for removal of the data from a buffer at the client. The method also includes selecting a mode for removal of the data from the buffer with a maximum required buffer size among the modes indicated by the information about the modes in the received message and removing the data from the buffer based on the identified mode. A method for indicating data removal management by a server includes generating and sending a message including information about a number of modes for removal of received data from a buffer at a client device. The information indicates, for each of the modes, a type of mode for removal of the data.

    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 method, decoder and server for managing buffers for rate pacing. The decoder includes a memory, a transceiver configured to transmit and receive a signal, and processing circuitry operably connected to the memory and the transceiver. The processing circuitry receives, from the server, a removal rate message indicating a drain rate of a pacing buffer of the decoder. The processing circuitry also provides packets from the pacing buffer to a decoding buffer of the decoder according to the drain rate.
