BROADCAST RECEIVER AND CONTROL METHOD THEREOF
First Claim
1. A broadcast receiver comprising:
- a signal receiver configured to receive a broadcasting signal of one frequency band among a plurality of frequency bands; and
a controller configured to determine presence or absence of a corresponding broadcasting signal for each of the plurality of frequency bands by checking properties of each of the plurality of frequency bands, and control a channel scanning operation to be performed,wherein the channel scanning operation is not performed with regard to one or more frequency bands in which it is determined that the corresponding broadcasting signal is absent.

Abstract
Disclosed are a broadcast receiver and a method thereof, in which channels are automatically scanned. The broadcast receiver includes: a signal receiver configured to receive a broadcasting signal of one frequency band among a plurality of frequency bands; and a controller configured to determine presence or absence of a corresponding broadcasting signal for each of the plurality of frequency bands by checking properties of each of the plurality of frequency bands, and control a channel scanning operation to be performed. The controller controls the signal receiver not to perform the channel scanning operation with regard to one or more frequency bands, in which it is determined that the corresponding broadcasting signal is absent.

7. A method of controlling a broadcast receiver, the method comprising:
-
individually receiving a broadcasting signal of one frequency band for each of a plurality of frequency bands; checking properties of each of the plurality of frequency bands; determining presence or absence of a corresponding broadcasting signal for each of the plurality of frequency bands; and controlling a channel scanning operation to be performed, wherein the channel scanning operation is not performed with regard to one or more frequency bands in which it is determined that the corresponding broadcasting signal is absent. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of programming broadcast channels, the method comprising:
-
checking each of a plurality of broadcast frequency bands for a corresponding frequency band energy level; determining the frequency bands having corresponding energy levels lower than a threshold value and the frequency bands not having corresponding energy levels lower than the threshold value; based on the determining, selecting broadcast frequency bands to be scanned for channel information; and scanning the selected broadcast frequency bands for channel information. - View Dependent Claims (14, 15, 16)
