Abstract: A user equipment (UE) configured to establish a multimedia data stream with a further UE, identify a predetermined condition, wherein the predetermined condition indicates a decrease in quality of the multimedia data stream at the further UE and implement a mechanism to mitigate the degradation of the decrease in quality of the multimedia data stream at the further UE.

Abstract: An integrated accessory control system can efficiently set up a new media streaming session with one or more accessories. A session identifier for the new session, as well as a destination address and security parameters can be generated. A data object comprising the generated elements can be written to a resource location. Additionally, a second data object comprising the session identifier, a streaming source address, a source identifier, and additional security parameters can be read from the resource location. A third data object comprising the session identifier, a session start command, and codec parameters can then be generated. The third data object can also be written to the resource location. Further, streamed media data conforming to the codec parameters and the security parameters may be received.

Abstract: A device implementing a system for audio-video conferencing using multiple stream identifiers includes a processor configured to receive, from a sending device, indication of a first content stream and a first stream identifier, and indication of a second content stream and a second stream identifier associated. The first content stream and the second content stream correspond to different bit rates of streaming content. The processor is configured to receive, from a receiving device, a request to subscribe to the second content stream, the request including the second stream identifier, and receive, from the sending device, an indication that the second stream identifier has been associated with the first content stream. The processor is configured to forward, to the receiving device, the first content stream based on the request to subscribe to the second content stream and on the indication that the second stream identifier has been associated with the first content stream.

Abstract: Techniques are disclosed relating to multiway communications. In some embodiments, a first electronic device initiates a multiway call between a plurality of electronic devices and exchanges a first secret with a first set of electronic devices participating during a first portion of the multiway call, the first secret being used to encrypt traffic between the first set of electronic devices. The first electronic device receives an indication that first set of participating electronic devices has changed and, in response to the indication, exchanges a second secret with a second set of electronic devices participating during a second portion of the multiway call, the second secret being used to encrypt traffic between the second set of participating electronic devices. In some embodiments, the indication identifies a second electronic device as leaving the multiway call, and the second secret is not exchanged with the second electronic device.

Abstract: This disclosure relates to inter radio access technology management for audiovisual calls. Wireless link availability and suitability for an audiovisual call may be evaluated for each of a first radio access technology and a second radio access technology. One or more wireless links on which to establish an audiovisual call may be selected based on the evaluations. The audiovisual call may be established on the selected wireless link(s). Wireless link availability and suitability for an audiovisual call may be monitored during the audiovisual call and decisions on whether to perform handover to a different wireless link and/or media duplication on multiple wireless links may be made based on the suitability for an audiovisual call of available wireless links.
