Patent ID: 7738850

Claim:
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; 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; a broadcasting output part; and a broadcasting signal processor which processes the broadcasting signal tuned in the RF module and outputs the tuned broadcasting signal to the broadcasting output part; wherein the wireless antenna has a determined length to meet a broadcasting frequency corresponding to one of a plurality of broadcasting channels, wherein the broadcasting output part comprises at least one of a display which displays a broadcasting picture according to the tuned broadcasting signal and a sound output part which outputs a broadcasting sound according to the tuned broadcasting signal.
