Receiver for receiving digital broadcast and method of optimizing power consumption in a receiver for receiving digital broadcasts

摘要

Provided are a digital broadcasting receiver which controls an antenna unit (110) according to a reception state of a digital broadcasting signal to optimize power consumption and a method of optimizing power consumption in the digital broadcasting receiver. The digital broadcasting receiver includes an antenna unit which includes an antenna (112) and an amplifying unit (114) for amplifying a digital broadcasting signal received through the antenna; a broadcasting signal processing unit (120) which processes the digital broadcasting signal output from the antenna unit and generates a bit stream; and a controlling unit (130) which checks a bit error rate of the generated bit stream and controls power consumption of the antenna unit based on the bit error rate. Thus, it is possible to control the antenna unit according to the reception state of the digital broadcasting signal to optimize the power consumption.
