    Abstract: Optimizing media distribution of a media steam performed by at least one processor, is provided, including: receiving immersive media data for an immersive presentation from a content source; acquiring asset information corresponding to media assets in a set of scenes included in the immersive media data; analyzing characteristics of the media assets, from the asset information, used in the set of scenes to determine whether a respective media asset is unique among the media assets; and generating metadata information that uniquely identifies the respective media asset for reusing the respective media asset in the set of scenes, based on determining that the respective media asset is not unique among the media assets in the set of scenes included in the immersive media data for the immersive presentation.

    Abstract: A method for streaming scene-based media assets during a media streaming session performed by a computing device is provided. The method includes providing a bi-directional interface for communicating information about scene-based media assets between a network server and the computing device acting as a client device; and providing, to the network server via the interface, client device attributes and corresponding information related to availability of client device resources when requested, wherein the client device attributes and the information are used by the computing device for rendering the scene-based media assets. For example, the computing device receives a request from the network server and then determines whether the requested scene-based media assets is to be streamed from the network server or not by accessing a list of locally stored, previously streamed scene-based media assets. The network server then generates the scene-based media assets or their proxies and inserts them into the media streaming session to be streamed to the computing device for rendering the scene-based media assets.

    Abstract: A method, device, and non-transitory computer-readable medium for decoding an encoded video bitstream using at least one processor, including obtaining a coded picture from the encoded video bitstream; decoding the coded picture to generate a decoded picture; obtaining a first flag indicating whether reference picture resampling is enabled; obtaining a second flag indicating whether reference pictures have a constant reference picture size; obtaining a third flag indicating whether output pictures have a constant output picture size indicated in the encoded video bitstream; generating a reference picture by resampling the decoded picture to have the constant reference picture size, and storing the reference picture in a decoded picture buffer; and generating an output picture by resampling the decoded picture to have the constant output picture size, and outputting the output picture.

    Abstract: Systems and method may provide unmanned aerial vehicle (UAV) connection monitoring and location reporting. A method implemented by at least one processor includes receiving a location report indicating a location of the UAV from a first server; receiving a lost connection report indicating a loss of connection with the UAV; receiving a connection resumption report indicating that the connection with the UAV has been re-established; and based on receiving the connection resumption report, transmitting a location update request to the first server.

    Abstract: A method of decoding an encoded video bitstream using at least one processor includes obtaining a coded video sequence including a plurality of output layer sets from the encoded video bitstream; obtaining a first flag indicating whether each output layer set of the plurality of output layer sets includes more than one layer; based on the first flag indicating that the each output layer set includes more than the one layer, obtaining a first syntax element indicating an output layer set mode; selecting at least one layer from among layers included in the plurality of output layer sets as at least one output layer based on at least one of the first flag and the first syntax element; and outputting the at least one output layer.

    Abstract: A method, computer program, and computer system for enabling peer-to-peer media streaming using service enabler architecture layer (SEAL). The method may be executed by one or more processors, and the method may include receiving, by a vertical application layer (VAL) server, a request for a media session negotiation between one or more client devices, and retrieving, by the vertical application layer (VAL) server, transport layer information associated with each of the one or more client devices using network address translation traversal. The method may further include transmitting, by the vertical application layer (VAL) server, agreed session description protocol (SDP) parameters based on the transport layer information, wherein the agreed session description protocol (SDP) parameters are used to establish a peer-to-peer media streaming session.
