Abstract: A broadcast signal receiving apparatus, a system including the same, and control methods thereof, are disclosed, the broadcast signal receiving apparatus including: a signal receiver configured to receive a radio frequency (RF) broadcast signal; an analog-to-digital (AD) converter configured to convert the received RF broadcast signal to have a digital format; a signal compensator including signal compensating circuitry configured to compensate the RF broadcast signal so that the RF broadcast signal having the digital format has a substantially constant level within a predetermined frequency band; and a digital-to-analog (DA) converter configured to convert the compensated RF broadcast signal to have an analog format. Thus, it is possible to compensate for signal distortion by automatic control using a digital filter in real time.

Abstract: Disclosed is a broadcast receiver that includes an antenna connector configured to connect with an antenna for receiving a broadcast signal including broadcast content. The broadcast receiver also includes a signal processor configured to generate a reference signal having a strength corresponding to a signal input through the antenna connector and to process the generated reference signal to output an image signal for displaying the broadcast content, and a controller configured to determine whether the antenna is connected to the antenna connector based on an output value of the reference signal and to perform subsequent operations related to whether the antenna is connected based on the determination.
