Abstract
A radio broadcast receiver for receiving digitally coded sound broadcasting data (DAB) includes a bit error rate measuring device. A control device controls the reproduction of the sound broadcasting data, wherein a reception quality threshold value is defined in the control device and, upon the measured reception quality falling below the threshold value, the control device alters the reception quality and/or the reproduction signals in a perceptible manner.
