Abstract: The invention relates to a device for receiving digital radio signals. Said device comprises a digital receiver with a tuner and a demodulator that is connected to the tuner, in addition to a first microcomputer. The demodulator and the first microcomputer are connected to an add-on module via a device interface of the digital receiver. Said module has second microcomputer and a signal processing unit that is controlled by the second microcomputer, the output of said unit being connected to the device interface. The inventive device further comprises a packet start detector, which prevents image, audio or data interference during the changeover of operating modes.

Abstract: The invention relates to a device for receiving digital radio signals. The device has a digital receiving appliance comprising a tuner and a demodulator that is connected to said tuner. The device also contains a first microcomputer. The demodulator and the first microcomputer are connected to a supplementary module by an appliance interface of the digital receiving appliance. Said supplementary module has a second microcomputer and a signal processing unit which is controlled by said second microcomputer and which is connected to the appliance interface at the output end. The supplementary module also contains at least one other signal output through which the signals that are processed in the signal processing unit can be output.
