摘要： 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.

摘要： 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.

摘要： Techniques disclosed herein permit a party to identify a first (low-resolution) image as it is displayed on their, for example, smart phone during a video conference call. Identifying information specific to the first image may be collected and a request for a high-resolution copy of the image sent to the party sourcing the transmitted image. The high-resolution image may be sent from the image's sourcing device to the requestor's device during, or after, the video conference call. In some embodiments, the high-resolution image may be sent through an alternate communication channel (e.g., via a chat, social media or email channel). In other embodiments, the high-resolution image may be sent to a network-based service from which the requestor may obtain the image. In one embodiment, the sourcing device may message the requesting device that the image has been sent to the network-based service.

摘要： 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.
