Disclosed are a broadcast signal receiving apparatus, a broadcast signal receiving system and a controlling method thereof, the broadcast signal receiving apparatus including: a demodulator configured to demodulate a satellite broadcast signal received through a relay capable of selectively receiving a broadcast signal corresponding to a voltage level of a signal; and at least one processor configured to output a control signal to the demodulator in response to channel selection for a broadcast signal, the demodulator outputting a command, which has a voltage level corresponding to the selected channel and includes channel information about the selected channel, in response to the control signal output from the processor so that a receiving band of the relay is changed in accordance with the channel selection for the broadcast signal. Thus, both the control of the LNB voltage and the generation and output of the DiSEqC command are implemented in the single element, thereby reducing the tuning fail and improving viewing circumstances/services and stability of the selected channel. |
