Abstract

A device for demultiplexing a packet-based transport stream of transport stream packets each provided with a systematic forward error detection code is described. The transport stream packets are each allocated to one of a plurality of data sinks, so that in a payload data section of the transport stream packets allocated to the same data sink a data stream of forward error protection code-protected data packets which are addressed to the respective data sink is embedded. The device determines, for a transport stream packet which is erroneous according to the systematic forward error detection code, a probability value for each of the plurality of data sinks which indicates how probable it is that the predetermined transport stream packet is allocated to the respective data sink, and allocates the predetermined transport stream packet to a selected one of the plurality of data sinks.
