This article surveys approaches to teleconferencing in voice over IP networks. The considerations for conferencing include perceived quality, scalability, control, and compatibility. Architectures used for conferencing range from centralized bridges to full mesh. Centralized conference bridges used with compressed speech degrade speech quality when multiple talkers are mixed and subjected to tandem coding operations. Full mesh and multicast solutions (mixing at the endpoints) are inappropriate… CONTINUE READING

U.S. Patent 5,390,177, Feb. 1995. Since TFC and decentralized conference endpoints receive the audio streams separately, some auxiliary user audio controls can be implemented entirely on the endpoint. For instance, per stream gain and recording controls, and 3-D audio rendering can be implemented w • 1995
