Claim:
1. A datacast information controller comprising: a memory storing instructions, content storage storing datacast information obtained by splitting a broadcast radio wave and datacast information storage storing the datacast information that includes keywords detected beforehand; and at least one processor configured to process the instructions to: determine whether the datacast information acquired from the content storage includes a specified keyword; compare datacast information determined to include the keyword with datacast information that is stored in the datacast information storage and includes the same keyword as the keyword; and instruct to display the datacast information determined to include the keyword in a specified manner of notification if the comparison shows that the datacast information determined to include the keyword does not match the datacast information including the same keyword; a datacast information display device, wherein if the specified manner of notification is to display on the datacast information display device, the datacast information determined to include the keyword is provided to the datacast information display device, wherein the at least one processor is configure to process the instructions to further extract a difference between current datacast information acquired from the content storage and prior datacast information acquired from the content storage prior to the acquisition of the current datacast information and, if the extraction shows that there is the difference, select the prior datacast information as a candidate for the datacast information to be displayed.
