Broadcasting signal processing apparatus and control method thereof
First Claim
1. A broadcasting signal processing apparatus comprising:
- a wireless antenna which receives broadcasting signals;
a radio frequency (RF) module which tunes a broadcasting signal received via the wireless antenna;
a variable part which adjusts an impedance to match an impedance of the wireless antenna with an impedance of the RF module, the variable part being coupled to the wireless antenna and the RF module; and
a controlling part which pre-stores impedance variable values for impedance matching between the wireless antenna and the RF module for broadcasting frequencies corresponding to respective broadcasting channels, 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.

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.

15. A control method comprising:
-
tuning to a broadcasting frequency of a broadcasting channel; determining whether an impedance used to match an impedance of a wireless antenna with an impedance of a radio frequency (RF) module is different from an impedance variable value for the tuned broadcasting frequency of the broadcasting channel; and if the impedance is different from the impedance variable value, adjusting the impedance based on the impedance variable value for the tuned broadcasting frequency of the selected broadcasting channel. - View Dependent Claims (16, 17, 18, 19)
