Abstract
In a digital TV broadcast signal receiver connected to a multi-directional antenna called smart antenna, having a first number, for example, sixteen of signal receiving directions defined in a technical standard such as EIA-909, a simplified multi-directional antenna having a second number, for example, four or eight signal receiving directions smaller than the first number is connectable. When a multi-directional antenna is connected, an initial processing is performed for confirming a number of signal receiving directions of the multi-directional antenna. When the multi-directional antenna is simplified one, the digital TV broadcast signal receiver treats the signal receiving directions more than two showing substantially the same signal sensing conditions as the same direction. Therefore, a number of times for switching the effective signal receiving direction of the multi-directional antenna can be reduced without switching indistinctive signal receiving directions in practice.
