PROBLEM TO BE SOLVED: To provide a technology of creating a two-dimensional code without violating the limitation of the number of nodes in data broadcasting even when the two-dimensional code has a large number of cells on one side.SOLUTION: A broadcasting station transmits material image patterns representing all two-dimensional arrange patterns of 2n black and white binaries, where n is the total number of cells (n=6, 7, 8, or 9), and a command description for causing a digital broadcast receiver to create a two-dimensional code image, by using data broadcasting. The digital broadcast receiver receives data broadcasting, converts predetermined information into two-dimensional code data on the basis of the instruction description, creates the two-dimensional code image corresponding to the two-dimensional code data by combining the material image patterns, and displays the two-dimensional code image. |
