ABSTRACT:
Teleconferencing and, in particular, distributed teleconferencing may use methods and systems for location grouping to reduce feedback and other audio anomalies. Terminals and users connected to the same teleconference and in the same location might not need to receive audio signals from the other terminals and users in the same location. As such, by detecting and analyzing the location of each participating terminal, the terminals (and thus, the users thereof) may be organized into location groups to provide proper audio mixing. In one example, first and second terminals in the same location might not receive each other's audio in a downstream teleconference signal. The location and grouping of terminals may be processed using context fingerprint information derived from sensor readings of each terminal. Sensors may include GPS sensors, cameras, BLUETOOTH sensors and the like. Context fingerprint information may further be synchronized to enhance location determination and grouping.
