A transmitter for transmitting an output signal includes first and second filter structures. The first filter structure includes a first combiner to extend a first data signal by a first reference signal to obtain a first extended data signal, and a first IIR filter for filtering the first extended data signal to obtain a first filtered data signal. The second filter structure includes a second combiner to extend a second data signal by a second reference signal, and a second IIR filter for filtering the second extended data signal. The transmitter includes a multiplexer for combining the first and second filtered data signals to obtain the output signal. A system response of the first IIR filter based on the first reference signal corresponds to a system response of the second IIR filter based on the second reference signal.

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.

Demultiplexing a packet-based transport stream

The inventive concept enables backward-compatible extension of existing interleaver-based transmission systems to the effect that in addition to an existing logical transport channel, which is interleaved using a standardized interleaver profile, further logical transport channels may be transmitted via the same physical transmission channel. In this context, the first transport channel obviously is reduced in terms of data rate, so that the additional transport channels may actually obtain a transmission capacity that is needed accordingly. Interleaver profiles of the further logical transport channels are derived, to this end, from the interleaver profile of the first transport channel.
