An antenna direction allocation screen is displayed on a television connected to a broadcasting receiver. On this screen, a user allocates direction numbers "0 to 15" indicating each directivity direction of a smart antenna that is assumed in a broadcasting receiver to each direction number "(0) to (15)" that the user itself can identity a direction. Then, the broadcasting receiver records a correspondence between two direction numbers. Next, the broadcasting receiver reads the direction number "(0) to (15)" corresponding to the direction number "0 to 15" indicating the directivity direction that the smart antenna actually faces, and displays its direction number on a television.
