ABSTRACT:
A transmitter for transmitting at least a first and a second main signal component is disclosed, having at least two input terminals for receiving the at least two input signals. The transmitter comprises multiplexer means for multiplexing the at least two input signals to a first input of matrixing means, and to an input of first bitrate reducing means. The first bitrate reducing means is for carrying out a data reduction step on the signal applied to its input and to supply a data reduced version to an output. Expansion means are present, having an input coupled to the first bitrate reducing means, for carrying out a data expansion on the data information applied to its input, so as to obtain a replica of the signal applied to the input of the bitrate reducing means at an output. Said output is coupled to a second input of the matrixing means. An output of the matrixing means is coupled to signal combination means via second bitrate reducing means. The output of the first bitrate reducing means is also coupled to the combination means. The signal combination means is adapted to combine the signals so as to enable the transmission of those output signals. Conversion means are provided between the input terminals and the inputs of the multiplexer means for converting the input signals into corresponding subsignals, such as subband signals. Further, a receiver for receiving the signals transmitted by means of the transmitter via the transmission medium, is disclosed.
