To shorten time required for decoding processing when decoding a packet signal containing a modulating system and an encoding rate as decoding information composed of a control code and a data code for decoding the data code into control code.
This device is provided with a distributor 10 for outputting the packet signal while separating it into the control code and the data code, plural decoders 21-2 6 for decoding the control code outputted from the distributor 10 and decoding the data code with respective modulating systems and encoding rates as many as the number of combination of the kinds of modulating systems and the kinds of encoding rates and a receiving side controller 30 as a selective output means for obtaining decoded information contained in the control code by analyzing the signal decoding the control code, and selectively outputting one of signals decoding the data code by means of plural decoders on the basis of that decoded information.
