## Abstract

A recording/reproduction system 100 operates a word retriever to retrieve a keyword from accumulated program information and operates a menu setting section to recognize the related word information KW related to the retrieved keyword and to generate menu index information based on the recognized related word information KW. A program classifier recognizes related number as related number information of content that relates to menu information Mi and classifies content of a program into menu information of the menu index information such that related number of programs related to each menu information Mi_n becomes substantially equal.
