Data information sent from a broadcast station 40 is decoded by an RDS decoder 22 into character information and character position information indicating the positions of the character information, and the character information and character position information are associated with each other and stored in the RAM 32. A character information extraction unit 34 extracts the character information stored in the RAM 32 and displays the character information on a display unit 28. A character information comparison unit 36 reads out first character information included in the data information and second character information stored in the RAM 32, which has the same character position information as the first character information, and compares the first character information and second character information. If the first character information and second character information are different, the character information extraction unit 34 deletes the character information stored in the RAM 32. |
