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: An example device for processing media data is configured to parse a bitstream including the media data, the bitstream being formatted according to Common Media Application Format (CMAF), detect, during the parsing, a file type (FTYP) value for a CMAF track file of the bitstream, determine that a CMAF header of the CMAF track file starts with the FTYP value, and process one or more CMAF fragments following the CMAF header of the CMAF track file. The device may additionally be configured to detect one or more segment type (STYP) values in the bitstream, determine that each of the one or more STYP values corresponds to a start of a respective one of the CMAF fragments, and process each of the CMAF fragments starting from the corresponding STYP value.

Abstract: The present disclosure relates to methods and devices for facilitating using a streaming manifest including a profile signal for content encoded based on a encapsulation format. An example method disclosed herein includes identifying structures associated with first media, wherein the first media is associated with a first streaming format. The example method also includes generating a streaming manifest for the first media, wherein the streaming manifest maps the structures associated with the first media to structures associated with a second streaming format, and including an indication with the streaming manifest, wherein the indication identifies the streaming profile used to map the structures.

Abstract: Various embodiments may provide streaming service downlink network assistance and/or uplink network assistance mechanisms in a fifth generation (5G) system (5GS) network via an Application Function (AF) computing device in a 5GS. In some embodiments, a computing device and/or the AF computing device may inform the network about needs for capacity for downlink or uplink traffic. Various embodiments may include sending radio access network (RAN) capacity requests to a network computing device of the 5GS network including a 5G RAN. In some embodiments, the network computing device of the 5GS network may be a computing device that is not part of the 5G RAN. In some embodiments, capacity need messages may be sent directly from user equipment (UE) computing devices to computing devices of the 5G RAN. In some embodiments, capacity information of the RAN may be delivered to an AF computing device via an intermediate network function.

Abstract: Systems and techniques are described for processing media content, such as samples of sparse media content whose sample durations can be unknown at the time of decoding the samples, include obtaining, at a current time instance, a current fragment comprising at least a current time component. From the current time component, a modified duration is obtained for at least one media sample, the modified duration indicating a time duration by which a presentation of a previous media sample of a previous fragment is to be extended or reduced in relation to the current time instance. The at least one media sample is presented for a time duration based on the modified duration.
