Abstract
A video system is disclosed that provides fast communication packet loss recovery. A source node generates a series of encoded video flames for a series of digitally sampled video flames by encoding each digitally sampled video frame relative to either an immediately preceding digitally sampled video frame or a previous digitally sampled video frame specified by a lost frame message received over the communication link from a destination node. The destination node receives the encoded video frames over the communication link and transfers the lost frame message to the source node if one of the encoded video frames is lost or delayed. The destination node generates the decoded version of each encoded video frame relative to either a decoded version of an immediately preceding encoded video frame or a decoded version of a last successfully received encoded video frame.
