Abstract

An encoding device for encoding a real time data stream for transfer over a noisy channel, the data stream comprising data bits in a succession of data packets, the system comprising: a data transmitter for sending said data bits in said packets in a utilization order, a data interleaver (70) for interleaving said data bits into an interleaved order, and an encoder (72) for encoding said data bits in said interleaved order to form parity bits for insertion into said data stream as a parity set, such that said parity bits are differentially distributed over said packets from said data bits.
