Patent number: 8493862Abstract: Devices and techniques for overcoming lost packets and avoiding congestion when conducting media conferences over packet switched networks are described herein. To avoid the problem of lost packets, redundant information is inserted into the media stream that permits the receiver to reconstruct any lost packets from the redundant information. Congestion avoidance techniques include adjusting the bitrate of the media stream to find the highest bitrate that can be supported without packet loss due to congestion. When increasing the bitrate to a higher rate, the additional bits can come from the redundant information used for lost packet recovery so that any lost packets caused by network congestion will not adversely affect the bitstream.Type: GrantFiled: December 14, 2010Date of Patent: July 23, 2013Assignee: Polycom, Inc.Inventors: Stephen Botzko, John Paul Spearman, Richard Flott, Jr., David Hein
