Broadcast signal receiving apparatus and controlling method thereof

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