摘要： In one embodiment, a participant device joins a collaboration session among a plurality of participant devices. The content shared within the collaboration session includes lower-priority data and higher-priority data. An initial available bandwidth for use with the collaboration session is determined. Based on the initial available bandwidth and an expected second bandwidth for higher-priority data shared within the collaboration session, a first bandwidth is allocated for lower-priority data shared within the collaboration session. During the collaboration session, an actual second bandwidth for the higher-priority data shared within the collaboration session is monitored. The expected second bandwidth is compared to the monitored actual second bandwidth, and a bandwidth variant is determined. Based on the determined bandwidth variant, the first bandwidth allocated for the lower-priority data shared within the collaboration session is adjusted to increase the bandwidth allocated for the lower-priority data.

摘要： In one embodiment, a method includes receiving requests to join a conference from a plurality of user devices proximate a first endpoint. The requests include a username. The method also includes receiving an audio signal for the conference from the first endpoint. The first endpoint is operable to capture audio proximate the first endpoint. The method also includes transmitting the audio signal to a second endpoint, remote from the first endpoint. The method also includes identifying, by a processor, an active speaker proximate the first endpoint based on information received from the plurality of user devices.

摘要： In one embodiment, a method includes capturing samples of sound associated with an environment, and processing the samples of sound to determine whether the samples of sound likely include voice activity. The samples of sound are captured while a microphone is muted. When it is determined that the samples of sound likely include the voice activity, the method also includes providing a first notification arranged to indicate that voice activity is detected and that the microphone is muted.
