Receiving apparatus, signal demodulating method, antenna apparatus, receiving system and antenna direction adjusting method

A method for displaying information of the antenna direction in a satellite broadcast receiving system comprising an antenna having an outdoor converter, a signal cable for supplying a signal from said converter, an indoor unit for receiving a signal from said converter through the signal cable, said method comprising the steps of:

• demodulating, at the indoor unit, an input signal from said converter;
• detecting, from a demodulated signal at the indoor unit, a detection signal representative of the direction of said antenna;
• modulating, at the indoor unit, said detection signal with a carrier signal;
• supplying, at the indoor unit, a modulated signal to said antenna through said signal cable;
• and
• displaying, at the antenna, information indicative of the antenna direction in response to a supplied modulated signal.
