The distribution section 200 includes auxiliary distributing sections for distributing the terrestrial broadcast signals input into the input ports PT1 to PT3 by each of distribution numbers 8, 6, 2 for each of the input ports PT1 to PT3. The distribution section 200 includes selection sections (relay R1 to R5) for selecting the terrestrial broadcast signals for 11 channels output from the distribution section 200, among the terrestrial broadcast signals output by the auxiliary distributing sections.
