摘要

The circuit arrangement has first tuner (4) which is used for the reception of analog signals as well as several channel-coded digital signals in at least two different procedures. The tuner possesses one or more intermediate frequency outlets to which several channel decoders working in the different procedures and an intermediate frequency integrated circuit (11) are attached. The transport current outlets are attached to a common transport current data bus (16). A central processor is in a position to activate or deactivate the various channel decoders as well as the intermediate frequency integrated circuit individually. The circuit arrangement has a second tuner (5) which possesses one or more intermediate frequency outlets to which at least a channel decoder is attached. The transport current outlets are attached to the common transport current data bus with at least a channel decoder. The transportation current data bus is exactly a moving picture experts group (MPEG) decoder (18).
