Abstract

To achieve an improved disparate error protection in the transmission of coded symbols of an information stream, the information stream is supplied to a multiplicity of coding branches for coding, and is supplied in parallel, to a puncturing and multiplexing unit. Symbols of different quality classes are fed into each coding branch using a demultiplexer. An interleaver follows at least one demultiplexer for generating error protection for the filtered symbols. The symbols, which may possibly be interleaved, are coded in each coding branch and are supplied to the puncturing and multiplexing unit. The puncturing and multiplexing unit sets a predetermined coding rate.
