Disclosed are a broadcast signal receiving apparatus, a broadcast signal receiving system and a controlling method thereof, the broadcast signal receiving apparatus comprising: a tuner configured to be tuned to a broadcast signal received from a signal source corresponding to a selected channel, and make at least a part of the received broadcast signal be looped through to an external apparatus in a normal mode; a switch configured to make the broadcast signal be looped through to the external apparatus in a standby mode of the tuner; and a controller configured to control operations of the tuner and the switch when the tuner is converted from the normal mode to the standby mode so that power can be supplied to or cut off from the tuner after a predetermined period of time. Thus, the switch is controlled independently of the mode of the broadcast signal receiving apparatus, thereby improving stability of operations and preventing a macroblock phenomenon of a broadcast signal looped through to an eternal apparatus.
