Patent ID: 7420627

Claim:
A digital television broadcast signal receiver in which a multi-directional antenna having multiple receiving directions is connected, and television broadcast signals are received by enabling one receiving direction, the receiver comprising: a control signal output unit for outputting control signals to specify a receiving direction for receiving television broadcast signals to the multi-directional antenna; a tuner, to which the multi-directional antenna is corrected, for receiving television broadcast signals, a memory for temporarily storing signal processed by the broadcast signal process method; a main controller for controlling a digital television broadcast signal receiver; an error detection unit which decodes television broadcast signal received by the tuner and detects a BER (Bit Error Rate) value; a memory for temporarily storing the BER value detected by the error detection unit; and a receiving direction determination unit for determining the best receiving direction for each receivable channel, based on the BER value stored in the memory, wherein the receiving direction determination unit consecutively scans all receiving directions of the multi-directional antenna for receivable channels and, when the BER value in each scanned receiving direction reaches a certain level that is lower than the set BER threshold which enables the reception of TV signals, determining a direction scanned at the time as the best receiving direction for the channel and stopping the scan there.
