A first request to form a conference call is received from a first of a plurality of electronic devices. In response to the first request, a conference data structure is generated in a memory. Based on determining the conference call has ended, a second request is transmitted to each of the plurality of electronic devices to return a high-resolution video stream generated by each electronic device during the conference call. In response to the second requests, the high-resolution video stream is received from at least some of the plurality of electronic devices. Each of the received high-resolution video streams is stored in the conference data structure in the memory to generate a completed conference data structure. A notice that the completed conference data structure is available is transmitted to each of the plurality of electronic devices.

High-quality audio/visual conferencing

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.

Video capture in low-light conditions

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.
