Abstract:
1. A method of encoding packet interdependency in a packet data stream, comprising: generating, via a plurality of data sources, a packet data stream through a video packet data transmitter, wherein the packet data stream comprises a plurality of data packets, each data packet carrying video data as payload; for each packet in said packet data stream, providing a relative displacement pointer (RDP) field associated therewith, said RDP field including a first direction dependency subfield and a second direction dependency subfield; representing dependency of a particular packet of said packet data stream by a first binary code in said first direction dependency subfield and a second binary code in said second direction dependency subfield, said first binary code for describing said particular packet's dependency on a packet disposed in one direction of said packet data stream and said second binary code for describing said particular packet's dependency on a packet disposed in an opposite direction of said packet data stream; and receiving said packet data stream by binary code for describing said particular packet's dependency on a packet disposed in one direction of said packet data stream and said second binary code for describing said particular packet's dependency on a packet disposed in an opposite direction of said packet data stream in a packet data receiver communicably coupled to the video packet data transmitter.
