Abstract: A device implementing the subject technology may include at least one processor configured to receive an indication of a task being performed at an other device. The at least one processor is further configured to perform, in response to receipt of the indication, one or more preliminary operations in anticipation of receiving a handoff of the task. The at least one processor is further configured to receive, after performing the one or more preliminary operations, a notification that the task is being handed off. The at least one processor is further configured to receive the handoff of the task from the other device. The at least one processor is further configured to continue to perform the task based at least in part on the one or more preliminary operations that were performed prior to receiving the notification that the task is being handed off.

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: In scenes that have low lighting, it may be difficult for a personal electronic device to capture video images that meet a scene lighting criteria. In some low-lighting situations, the receiving party may be unable to sufficiently see the face of the party that they are videoconferencing with. Described herein are techniques for utilizing a device's display to illuminate the scene surrounding the device. Improved lighting may come from global display adjustments, local display adjustments that do not alter the display's contents (other than to change their brightness levels), and/or local display adjustments that alter the display's contents. In some embodiments, background elements on a device's display may be identified for brightening in a first attempt to meet the scene lighting criteria without negatively impacting foreground scene content. If such approaches are unsuccessful, the device may next replace one or more regions of displayed content with regions of brightened pixels.

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.
