Multi-channel broadcasting receiver and method for realizing power-saving mode therefor
First Claim
1. A multi-channel broadcasting receiver, comprising:
- an analog broadcasting processor for receiving and outputting an analog broadcast signal;
a digital broadcasting processor for receiving and outputting a digital broadcast signal;
a broadcasting selector for selecting and outputting one of the broadcast signals outputted by the analog broadcasting processor and the digital broadcasting processor;
a power supply for controlling power supplied to the digital broadcasting processor to realize a power-saving mode; and
a controller for controlling operations of the broadcasting selector and the power supply in response to an external operational signal.

Abstract
A multi-channel broadcasting receiver (e.g., a set-top box or STB) and a method for realizing a power-saving mode thereof are provided. The STB includes: an analog broadcasting processor for receiving and outputting an analog broadcast signal; a digital broadcasting processor for receiving and outputting a digital broadcast signal; a broadcasting selector for selecting and outputting one of the analog and digital broadcast signals; a power supply for controlling power supplied to the digital broadcasting processor to realize a power-saving mode; and a controller for controlling the operations of the broadcasting selector and the power supply in response to an external operational signal. The method for realizing the power-saving mode comprises: receiving an external operation signal for selecting a loop-through function; selecting and outputting the signal from the analog broadcasting processor; and blocking power from being supplied to the digital broadcasting processor. Accordingly, power consumption and waste in processing the digital broadcast signal when the analog broadcast signal is being outputted is prevented, and heat generated in the STB is reduced, thereby enhancing the durability of the STB.
