Abstract
An apparatus and method enable easy extraction of popular programs from program information. A keyword extracting section extracts keywords from program information received by a program information receiving section. A keyword counting section counts a number of keywords for one week among the extracted keywords to obtain a keyword count for that week. A difference value computing section computes a difference value between the keyword count for the current week and the keyword count for the past week. A popular keywords extracting section extracts a predetermined number of keywords in a descending order of difference values each indicating a difference between the keyword count for the current week keywords and the keyword count for the past week keywords, and sets the keywords as those for the current week.
