Patent ID: 8830332

Claim:
An electronic device comprising: a receiving unit configured to receive a broadcast signal comprising a high-speed transmission channel and a low-speed transmission channel, the high-speed transmission channel comprising different combinations of error resistance and transmissible video signal quality than the low-speed transmission channel; a first measuring module configured to measure a carrier-to-noise power ratio (CN) of the broadcast signal; a second measuring module configured to measure a reception power of the broadcast signal; and a control module configured to: estimate the CN when the electronic device is in an environment corresponding to a stationary state, based on the measured reception power, a reception sensitivity for receiving a broadcast service of the high-speed transmission channel, and a first CN for receiving the broadcast service of the high-speed transmission channel, and switch a demodulation target broadcast service between the high-speed transmission channel and the low-speed transmission channel based on a difference between the estimated CN and the measured CN.
