Abstract: Media data of a first scene graph is received. The first scene graph is created based on a first scene graph format. The first scene graph format includes a plurality of description components indicating attributes of the first scene graph. A plurality of metadata identifiers associated with the first scene graph format and a plurality of metadata identifiers associated with a second scene graph format are determined based on a lookup table. The lookup table identifies metadata identifiers associated with the first and second scene graph formats. A plurality of description components of the second scene graph format that indicates the attributes of the first scene graph is determined based on (i) the plurality of description components of the first scene graph format, (ii) the plurality of metadata identifiers associated with the first scene graph format, and (iii) the plurality of metadata identifiers associated with the second scene graph format.

Abstract: In a method of media streaming in a client device, a media stream carrying media content is received. The media content from the media stream is presented. A request that the client device provide media asset information is received from a server device and according to a bidirectional protocol for immersive media distribution. The media asset information is sent to the server device by the client device and according to the bidirectional protocol. The media asset information indicates at least one media asset location of a media asset that is accessible to the client device.

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 is performed by a network node connected to one or more additional network nodes via a local area network (LAN). The network node and the one or more additional network nodes form a cloud. The method includes setting a first timer to a first value, the first timer being associated with determining whether one of the one or more additional network nodes is an active controller in the cloud. The method includes starting the first timer. The method includes determining, before the first timer expires, whether a first message that indicates the one of the one or more additional network nodes is the active controller is received. Based on determining the first message is received before the first timer expires, the method includes synchronizing with the one of the one or more additional network nodes that is the active controller, and restarting the first timer.

Abstract: Aspects of the disclosure provide methods and apparatuses for media processing. In some examples, an apparatus includes processing circuitry. The processing circuitry exchanges, with a server device and according to a bidirectional protocol for immersive media, a first plurality of messages that ensures the server device to receive one or more specific characteristics of the apparatus. The processing circuitry receives, from the server device and according to the bidirectional protocol for immersive media, a media stream carrying media content. The media stream includes immersive content and is adapted according to the one or more specific characteristics of the apparatus. The processing circuitry presents the media content from the media stream.
