Abstract  Abstract

The invention relates to a digital transmission system having a transmitter and a receiver for transmitting and receiving a digital stereo audio signal comprising a left and right hand signal component via/from a transmission medium. The transmitter comprises analysis filter means for filtering the signal components so as to obtain a number of n sub signals for each of the left and right hand signal components and transmission means for transmitting sub signals via the transmission medium. The receiver comprises means for receiving the sub signals and decoding them by means of synthesis filter means so as to obtain a replica of the stereo audio signal. In accordance with the invention the transmitter further comprises signal combination means for combining at least one corresponding sub signal of the left and right hand signal components so as to obtain a composite sub signal and control signal generator means for generating a sub signal indicator control signal indicating said at least one sub signal of the left and right hand signal components being combined. The transmitter is further adapted to transmit said composite sub signal and said sub signal indicator control signal. The receiver receives said sub signal indicator control signal and said composite sub signal and derives therefrom in response to the sub signal indicator control signal sub signals for the left and right hand signal components. The invention enables thereby a further data reduction of the sub(band) signals to be transmitted.
