Abstract

The present invention, an antenna apparatus and its system of a digital TV, includes a plurality of antenna units, an antenna switching circuit, and a digital TV module. The antenna units receive a RF signal transmitted from a transmission terminal. The antenna switching circuit converges on the RF signal and transfers the RF signal into an antenna signal. The digital TV module receives the antenna signal and transmits a control signal to the antenna switching circuit. Through the control signal and digital TV channel chosen by users, frequency signal of channels can be inputted into the digital TV module through the antenna switching circuit to perform demodulation and decoding process, and finally outputs a video/audio signal.
