PROBLEM TO BE SOLVED: To provide a joint reception device that receives a 1st broadcast signal, an output signal of a 2nd satellite reception converter, and an output signal of a 3rd satellite reception converter at its respective terminals, mixes them and outputs the mixed signal and receives 4th incoming signals from output terminals, to output them to the input terminal of the 1st broadcast signal. SOLUTION: A filter separates a signal with a 1st signal frequency and a signal with a 4th signal frequency, a filter synthesizes a signal with a 2nd signal frequency with a signal with a 3rd signal frequency, a filter synthesizes the signal with the 1st signal frequency, the signal with the 2nd signal frequency, and the signal with the 3rd signal frequency, a distribution circuit distributes the combines signal into two, the one is outputted from a 2nd output terminal, a filter combines the one signal with the signal with the 4th signal frequency, the signal with the 1st signal frequency, the signal with the 2nd signal frequency, and the signal with the 3rd signal frequency are outputted from a 1st output terminal, and the signal with the 4th signal frequency can be outputted from an input terminal of the 1st signal frequency. |
