Abstract:
A method of coding a sequence of data packets representing a stream of information, the data packets to be transmitted across a communications network, each data packet comprising a set of payload information representative of a segment of said stream of information corresponding thereto, the method comprising the steps of:(a) coding for transmission a first data packet, said encoded first data packet comprising a first set of payload information representative of a first segment of said stream of information; and (b) coding for transmission a second data packet subsequent to said first data packet in said sequence of data packets, said encoded second data packet comprising a second set of payload information representative of a second segment of said stream of information subsequent to said first segment of said stream of information, said encoded second data packet further comprising an additional set of payload information, said additional set of payload information also representative of said first segment of said stream of information but not representative of other segments of said stream of information, wherein said additional set of payload information and said first set of payload information comprise redundant encodings of said first segment of said stream of information, wherein an approximated reconstruction of said first segment of said stream of information is producible based on a decoding of said first set of payload information alone, and wherein an approximated reconstruction of said first segment of said stream of information is producible based on a decoding of said additional set of payload information alone.
