Abstract:
In a telecommunications network including a first device and a second device, said telecommunications network comprising a packet-switched network, said first device transmitting a plurality of data streams in parallel to said second device, said data streams comprising data packet streams each defining a sequence of data packets, an improved method of communicating said plurality of data streams comprising, in combination:combining together at least two of said plurality of data streams in parallel to generate parallel FEC information, wherein a first of the at least two data streams represents media originating from a first source, wherein a second of the at least two data streams represents media originating from a second source different that the first source, and wherein said parallel FEC information comprises parallel FEC packets derived as a functional combination of the data packets defined by at least two of said data packet streams; labeling said parallel FEC packets with a predetermined header identifying said packets as parallel FEC packets; and transmitting said parallel FEC information to said second device in parallel with said plurality of data streams.
