A frame number of a frame in interest (playback position identification information) in which a correlated region can be traced based on a certain initial reference region (for example, an interesting region on which user-designated addresses concentrate), position coordinates of an interesting region (coordinates identification information), and position coordinates of the correlated region (coordinates identification information) are associated with designation information as interest information and stored in the interest information DB. An analyst of user interest (a distributor of related information) can know which element in a content a user is especially interested in by collating the actual moving image content with the interest information and can register appropriate related information based on the interest. |
