Abstract: 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.

Abstract translation: 从广播站40发送的数据信息由RDS解码器22解码为字符信息和表示字符信息的位置的字符位置信息，并且字符信息和字符位置信息彼此相关联并存储在RAM 32中。 字符信息提取单元34提取存储在RAM32中的字符信息，并将字符信息显示在显示单元28上。字符信息比较单元36读出包含在数据信息中的第一字符信息和存储在RAM中的第二字符信息 32，其具有与第一字符信息相同的字符位置信息，并且比较第一字符信息和第二字符信息。 如果第一字符信息和第二字符信息不同，则字符信息提取单元34删除存储在RAM 32中的字符信息。
