Systems, methods, and devices for managing media storage and delivery, including obtaining, by a media access function (MAF), a Graphics Language Transmission Format (glTF) file corresponding to a scene; obtaining from the glTF file a uniform resource locator (URL) parameter indicating a binary data blob; determining that the binary data blob has a Concise Binary Object Representation (CBOR) format; converting the binary data blob into an object having a JavaScript Object Notation (JSON) format using a CBOR parser function implemented by the MAF; and obtaining media content corresponding to the scene based on the object.

Method and apparatus for media scene description

A method of processing media content in Moving Picture Experts Group (MPEG) Network Based Media Processing (NBMP) includes obtaining a plurality of tasks for processing the media content, providing an interface between an NBMP workflow manager and a cloud manager by providing an NBMP Link application program interface (API), which links the plurality of tasks together, identifying an amount of network resources to be used for processing the media content, by using the NBMP Link API, and processing the media content in accordance with the identified amount of network resources.

Interoperable cloud based media processing using dynamic network interface

Aspects of the disclosure provide methods and apparatus for accessing a Constrained Application Protocol (CoAP) server in a media scene description system. A CoAP request can be sent, by a media access function (MAF) of processing circuitry implementing the media scene description system using an application programming interface (API), to the CoAP server to request a media resource. The MAF can be configured as a CoAP client or a Hypertext Transfer Protocol (HTTP)-CoAP proxy. A CoAP response can be received, by the MAF using the API, from the CoAP server. In an example, the CoAP response includes the requested media resource. In an embodiment, the MAF is compatible with both the CoAP request according to a CoAP communication protocol and a proxy request according to an HTTP communication protocol.

Using Coap protocol for video streaming

Systems, methods, and devices for managing media storage and delivery, including obtaining, by a media access function (MAF), a glTF file corresponding to a scene; determining that the glTF file has a CBOR format; converting the glTF file into a converted glTF file having a JSON format using a first CBOR parser function implemented by the MAF; and obtaining media content corresponding to the scene based on the converted glTF file.

In a method of group creation for a pair of an unmanned aerial vehicle (UAV) and an unmanned aerial vehicle-controller (UAV-C) in a service enabler architecture layer (SEAL) architecture, the pair of UAV and UAV-C is determined by an unmanned aerial system application enabler (UAE) server in the SEAL architecture. A group creation request for the pair of UAV and UAV-C is transmitted by the UAE server to a SEAL group management (GM) server of the SEAL architecture. A first response message is received by the UAE server from the SEAL GM server for the group creation request. A group including the pair of the UAV and the UAV-C is created for quality-of-service (QoS) management. The group creation request includes an identity of an UAE client corresponding to the pair of UAV and UAV-C, an identity of the UAV, and an identity of the UAV-C.

Method and apparatus for UAV and UAV controller pairing and command and control (C2) quality of service provisioning

Systems, methods, and devices for managing media storage and delivery, including obtaining information about a three-dimensional (3D) scene; obtaining, from the information, a parameter indicating that viewport adaptation is enabled; rendering the 3D scene, wherein the 3D scene includes at least one two-dimensional (2D) video to be reproduced within the 3D scene; obtaining a current viewport of a user; determining whether the at least one 2D video is inside of a range of the current viewport; and adjusting a bitrate of the at least one 2D video based on a result of the determining.

In a method of real-time network monitoring and location updating, a location report is received by an unmanned aerial system application enabler (UAE) server from a location management (LM) server. The location report indicates location information of a user equipment (UE). A first network event notification associated with the UE is received by the UAE server from a network resource management (NRM) server. The first network event notification indicates a connection status of the UE with a network. In response to detecting a re-connected status of the UE, a second networking event notification is received by the UAE server from the NRM server. The second networking event notification indicates that the UE reconnects to the network. Further, (i) the second networking event notification, (ii) an identity of the UAE server, and (iii) most recently updated location information of the UE from the LM server are recorded by the UAE server.

Method and apparatus for real time UAV connection monitoring and location reporting

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.

Unmanned aerial system communication

A method of a service enabler architecture layer (SEAL) can include receiving a monitoring event subscription request for network connection status information at a network resource management server in the SEAL from a vertical application layer (VAL) server. The monitoring event subscription request can indicate a target VAL user equipment (UE), a type of the network connection status information, and a timeout period indicating an amount of time lapsed after the monitoring event subscription request was transmitted. The requested network connection status information is not transmitted after the timeout period. The network connection status information of the target VAL UE can be obtained from a wireless network system. A network connection status information response message can be transmitted from the network resource management server in the SEAL to the VAL server. The network connection status information response message can include the network connection status information of the target VAL UE.

Network monitoring in service enabler architecture layer (SEAL)

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.

A method of obtaining a tree-based point cloud compression (PCC) media stream using moving picture experts group (MPEG)-dynamic adaptive streaming over http (DASH), is performed by at least one processor and includes obtaining, from a server, a media representation description (MPD) comprising a PCC uniform resource indicator (URI) and a PCC three-dimensional (3D) descriptor, and determining whether the PCC URI comprised in the obtained MPD indicates that the tree-based PCC media stream is to be accessed. The method further includes, based on the PCC URI being determined to indicate that the tree-based PCC media stream is to be accessed, obtaining, from the server, the tree-based PCC media stream, using the PCC 3D descriptor comprised in the obtained MPD.
