摘要

A recording/reproducing system (100) causes word retrieving means to retrieve a key word from stored program information and menu setting means to recognize related word information (KW) related to the key word retrieved, so that menu index information is generated on the basis of the related word information recognized. Program classifying means recognizes a relation number as the relation number information of contents related to menu information (Mi), and classifies the contents of a program into the menu information of the menu index information so that the related number of the programs related to the menu information (Mi_n) may be uniform.
