FIELD: radio engineering, communication.SUBSTANCE: device for demultiplexing a packet-based transport stream (14) consisting of transport stream packets (12), each provided with a systematic forward error detection code. Each of the packets is allocated to one of a plurality of data sinks (20), so that in a payload data section of the transport stream packets allocated to the same data sink (20) a data stream (36) of forward error protection code-protected data packets (38) which are addressed to the respective data sink (20) is embedded. The device determines, for a predetermined transport stream packet (12) 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 (12) is allocated to the respective data sink (20), and based on the probability values for the plurality of data sinks, allocates the predetermined transport stream packet to a selected one of the plurality of data sinks.EFFECT: more efficient transmission of data to a data sink.18 cl, 3 dwg |
