Abstract: A method includes, at a media bridge configured to distribute a plurality of media streams among a plurality of client devices connected to the media bridge over a network, receiving the plurality of media streams from the plurality of client devices via the media bridge. The media bridge connects the plurality of client devices. The method further includes assigning a pair of names for each of the plurality of media streams. The pair of names include a contribution name and a distribution name. The method further includes presenting a first list to the plurality of client devices. The first list including a plurality of the distribution names for the plurality of media streams received from the plurality of client devices. The method further includes providing an indication of a current active speaker within the plurality of media streams via a signaling process.

Abstract: A method includes, at a media bridge configured to distribute a plurality of media streams among a plurality of client devices connected to the media bridge over a network during a real-time communication (RTC) instance, receiving a plurality of quality of experience (QoE) preferences from the plurality of client devices via the media bridge, the plurality of QoE preferences being transmitted as a real-time transport protocol (RTP) control protocol (RTCP) extension header of a transmitted data packet. The method also includes receiving a plurality of QoE metrics at the media bridge, and in response to a determination that a degradation in network conditions of the network has occurred, downgrading at least one of the plurality of media streams based on the plurality of QoE preferences.

Abstract: This disclosure describes techniques for controlling group access to a collaboration technology. The techniques include generating a shared encryption key among authorized producers of content associated with a collaboration technology. The techniques include receiving, by the authorized producers and from authenticated consumers, requests to access the content. The requests may be received in a partitioned manner, such that individual producers are serving a particular subset of the authenticated consumers. In response to receiving the requests, the techniques include sending the shared encryption key from the individual producers to the corresponding subset of authenticated consumers. The techniques include using the shared encryption key to encrypt content by the authorized producers, which may then be decrypted by the authenticated consumers using the shared encryption key, achieving end-to-end encryption of event content.
