A direct satellite broadcast receiver includes an indoor unit (10) for receiving a broadcast signal transmitted from a stationary artificial satellite and received through an antenna (1) installed outdoors. A signal input terminal (4) is provided at the indoor unit (10) to which the signal from the antenna (1) is supplied through a cable (3), a demodulating circuit (16) demodulates the input signal at the input terminal (4) into a television signal, a level detecting circuit (31) detects the signal level at the input terminal (4), and a signal superimposing circuit (34) superimposes the output signal from the level detecting circuit (31) on the output signal of the demodulating circuit (16), whereby the input signal level at the input terminal (4) is displayed on a television picture screen (36). |
