A main information display part 111 indicates the main information as electric light characters or a television image. The auxiliary service part 120 converts the auxiliary information into multi-dimensional dot codes expressed by two-dimensional dots by means of an encoding part 121 and displayed the multi-dimensional dot codes by controlling lighting by a pixel unit of a multi-dimensional dot code display part 122 in which pixel units are arranged two-dimensionally. If the user has interest in the main information, the user photographs the multi-dimensional dot code display part 122 by means of a camera part 210 and obtains the auxiliary information by decoding the photographed image by a decoding part 220. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
