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.
