<p>Provided are a method and system for supplying power in a feeding manner, and a digital TV receiving terminal. The method comprises: a digital TV receiving terminal receiving a mixed signal which is formed by mixing a TV signal, a data signal and an alternating current and then transmitted via a cable, and isolating the alternating current in the mixed signal and providing same to each component of the digital TV receiving terminal for power supply; and isolating the TV signal and the data signal in the mixed signal and providing same to a high/low pass filter, and the high/low pass filter separating high-frequency TV signals and low-frequency data signals and outputting same. The method in the present invention achieves the purposes of supplying power to a digital TV receiving terminal and uniformly transmitting TV signals and data signals without using an external adapter to supply power, thereby effectively reducing the terminal cost.</p> |
