To avoid disturbance due to a signal resulting from a frequency differ ence of oscillated signals between respective 1st local oscillators of two fre quency converters.
The 1st and 2nd frequency converters 1, 2 respectively have 1st mixers 1b, 2b that frequency-convert a received intermediate frequency band television signal into a 1st intermediate frequency band television signal, 1st local oscillators 1c, 2c that give a 1st local oscillation signal to the 1st mixers 1b, 2b, 2nd mixers 1f, 2f that frequency-convert the 1st intermediate frequency band television signal into a broadcast channel television signal, and 2nd local oscillators 1g, 2g that give a 2nd local oscillation signal to the 2nd mixers 1f, 2f. The frequency of the 1st local oscillation signal being the output of the 1st frequency converter 1 is differentiated by 0.25 MHz or over from the frequency of the 1st local oscillation signal being the output of the 2nd frequency converter 2.
