Abstract
A broadcasting signal processing apparatus and a control method thereof are provided. The broadcasting signal processing apparatus includes a wireless antenna; a radio frequency (RF) module which tunes a broadcasting signal; a variable part which adjusts an impedance to match an impedance of the wireless antenna with an impedance of the RF module; and a controlling part which pre-stores impedance variable values for impedance matching and which controls the variable part to adjust the impedance based on one of the pre-stored impedance variable values corresponding to a broadcasting frequency of a selected broadcasting channel. The method includes tuning to a broadcasting frequency; determining whether an impedance used to match a wireless antenna with a radio frequency (RF) module is different from an impedance variable value; and if the impedance is different, adjusting the impedance.
