Abstract

An apparatus for assigning transmission symbols to a media data stream of information symbols is described, the media data stream including a first substream for representing media content in a basic quality and a second substream including additional data for representing the media content, along with the first substream, in an improved quality. The apparatus includes a first assigner for assigning first transmission symbols to the information symbols of the first substream and a second assigner for assigning second transmission symbols to the information symbols of the second substream, the first transmission symbols being transmissible, via a transmission channel, with reduced error probability as compared to the second transmission symbols.
