Patent ID: 7818772

Claim:
A system for improving quality of video communication over a packet-based network, comprising: a packets generator logical unit (PGU) coupled to a video source for receiving a compressed video stream and processing the compressed video stream to generate a stream of primary data chunks and a stream of secondary data chunks, each secondary data chunk associated with a primary data chunk, and to generate packets from the stream of primary data chunks and secondary data chunks; and a network controller coupled to the PGU and coupled to the packet-based network for sending the packets to one or more destination nodes, wherein the PGU delays sending each secondary data chunk with respect to its associated primary data chunk, wherein each secondary data chunk contains data corresponding to at least a portion of a video frame covered by the corresponding primary data chunk, and wherein the secondary data chunk is delayed such that it arrives at the one or more destination nodes after the associated primary data chunk but before a declaration by the one or more destination nodes that the associated primary data chunk is lost.
