Abstract: An example method includes sending or receiving a session description protocol (SDP) message that includes binding information that associates a first RTP header extension and a second RTP header extension for an RTP session, wherein the binding information is indicative of a first timestamp in the first RTP header extension, and the first timestamp in the second RTP header extension, both being indicative of a time at which a first RTP packet including the first RTP header extension is transmitted. The method includes transmitting, by a first device, the first RTP packet and receiving, by the first device, a second RTP packet, the second RTP packet including the second RTP header extension including the first timestamp, a second timestamp, and a third timestamp. The method includes determining, based on at least one of the first timestamp, the second timestamp, or the third timestamp, a delay.

Abstract: An example server device for sending media data includes a memory configured to store media data; and a processing system implemented in circuitry and configured to: receive a set of three-dimensional (3D) media data being sent to a client device; transcode the set of 3D media data to a set of one or more images; and send the set of one or more images to the client device. The server device may receive a message from a source client device destined for the client device, where the message includes the 3D media data. The message may be a Multimedia Message Service (MMS) message including the 3D media data. The client device may initially provide data representing rendering capabilities of the client device to the server device, such that the server device may determine that the client device is not capable of rendering the 3D media data.

Abstract: An example device for retrieving media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to execute a presentation engine, the presentation engine being configured to: receive streamed media data representing a virtual three-dimensional scene including at least one virtual solid object; receive object collision data representing boundaries of the at least one virtual solid object; receive camera movement data from a user requesting that the virtual camera move through the at least one virtual solid object; and using the object collision data, prevent the virtual camera from passing through the at least one virtual solid object in response to the camera movement data.

Abstract: An example device for retrieving media data, the device comprising: a memory configured to store scene data and image data; and one or more processors implemented in circuitry and configured to: receive data for a bitstream indicating that the bitstream includes one or more overlay images, the overlay images comprising either a single static image to be presented with scene data that remains constant while being presented frame-by-frame with frames of the scene data or an image sequence that repeats with a regular periodicity while being presented frame-by-frame with the frames of the scene data; receive the one or more overlay images from the bitstream; receive the scene data including one or more scene images; and present the scene images and the overlay images.

Abstract: A client device (e.g., user equipment or “UE”) may be configured to engage in a media communication session, such as a WebRTC session, with another client device. The client devices may separate a quality of service (QoS) specification from a QoS flow definition, to allow for separate interactive connectivity establishment (ICE) negotiation. The QoS specification may cover all segments of a connection for the media communication session. For example, QoS may be requested for a case where a server (e.g., a Traversal Using Relay Network Address Translation (TURN) server) is hosted by a mobile network operator (MNO). The QoS specification and the QoS flow description may be linked.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, by an edge enabler client of the UE, to trigger generation of a shadow application context to support an application that is associated with an application context and that is served by an edge network device. The UE may determine, by the edge enabler client, to transfer support of the application from the application context to the shadow application context, and transfer, by the edge enabler client, support of the application from the application context to the shadow application context. In some aspects, an application context may be transferred between a UE and an edge network directly, without the shadow application context. Numerous other aspects are provided.
