Lost Packet Recovery

Lost Packet Recovery allows users to communicate over video from any network in any location and know the quality will be high and their message will be understood. Polycom has implemented LPR technology from end to end – on room video systems to desktop and tablet software to media and bridging platforms.


Network errors during a video call, no matter how small or large can take away from the overall experience. Being able to maintain high quality video and audio from any device on any network is the goal for Polycom and Lost Packet Recovery (LPR) technology. The algorithm allocates a small amount of bandwidth for forward error correction (FEC) eliminating the typical hiccups that are found on lesser quality networks like freezing or blocky video and stuttered audio.

Patent

Polycom Lost Packet Recovery Patent 7,876,685

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.
