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.

Description

technical field [0001] Apparatuses and methods consistent with exemplary embodiments relate to a broadcast receiver and a control method thereof, and more particularly, to a broadcast receiver in which automatic setting of a plurality of channels can be quickly performed and a control method thereof. Background technique [0002] In digital broadcast receivers such as televisions (TVs), set-top boxes, etc., broadcast channels are automatically scanned, and channel numbers associated with broadcast frequencies of received signals are stored in a memory of the digital broadcast receiver. [0003] When a user requests an automatic broadcast channel scanning operation, the controller controls the element tuned for receiving signals to scan broadcast frequency bands. [0004] In addition, the controller associates the channel number with the broadcast frequency of the detected signal, and stores the channel number as channel information. [0005] When a user requests channel up / ...
