- 1. A system for improving quality of video communication over a packet-based network, comprising: na 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.
- 22. A method for improving quality of video communication, comprising the steps of: nreceiving a compressed video stream, the compressed video stream having a plurality of fields; parsing the plurality of fields from the compressed video stream and determining field types; generating secondary data chunks and primary data chunks based on the field types, each secondary data chunk associated with a primary data chunk; delaying each secondary data chunk with respect to its associated primary data chunk; generating packets from the delayed secondary data chunks and primary data chunks; and sending the packets to one or more destination nodes.
- 34. An electronic-readable medium having embodied thereon a program, the program being executable by a machine to perform method steps for improving quality of video communication, the method steps comprising: nreceiving a compressed video stream, the compressed video stream having a plurality of fields; parsing the plurality of fields from the compressed video stream and determining field types; generating secondary data chunks and primary data chunks based on the field types, each secondary data chunk associated with a primary data chunk; delaying each secondary data chunk with respect to its associated primary data chunk; generating packets from the delayed secondary data chunks and primary data chunks; and sending the packets to one or more destination nodes.
- 41. A system for improving quality of video communication, comprising: nmeans for receiving a compressed video stream, the compressed video stream having a plurality of fields; means for parsing the plurality of fields from the compressed video stream and determining field types; means for generating secondary data chunks and primary data chunks based on the field types, each secondary data chunk associated with a primary data chunk; means for delaying each secondary data chunk with respect to its associated primary data chunk; means for generating packets from the delayed secondary data chunks and primary data chunks; and means for sending the packets to one or more destination nodes.
