Television broadcast signal receiving system
First Claim
1. A television broadcast signal receiving system comprising a multi-directional antenna having a plurality of signal receiving directions previously defined and a television broadcast signal receiver connected to the multi-directional antenna for receiving a television broadcast signal, wherein the multi-directional antenna has a standard direction identifying means for identifying a standard direction used as a standard for receiving a television broadcast signal;
- and the television broadcast signal receiver has a television tower direction identifying means for identifying directions of television towers relative to a location of the multi-directional antenna with respect to the standard direction, and an optimum signal receiving direction deciding means for deciding optimum signal receiving directions of receivable channels which are used for switching an effective signal receiving direction of the multi-directional antenna for receiving a television broadcast signal of an optional channel chosen by a user with using the directions of the television towers.

Abstract
In a TV broadcast signal receiving system, setting up of a multi-directional antenna and a TV broadcast signal receiver is made simple and easy. The multi-directional antenna identifies a standard direction used as a standard for receiving a TV broadcast signal, at least latitude and longitude of a location of the multi-directional antenna. The TV broadcast signal receiver memorizes TV tower information including position information of latitudes and longitudes of positions of a plurality of TV towers and channel information of channels, TV broadcast signals of which are transmitted from each TV tower. The TV broadcast signal receiver decides an optimum signal receiving direction of each receivable channel with using the antenna information and the TV tower information, which is used for switching an effective signal receiving direction of the multi-directional antenna for receiving a TV broadcast signal of an optional channel chosen by a user.
