Whether or not the duration of the section, the start and end positions of which are detected, is a predetermined duration is detected (ST104). When it is detected that the duration of the section is the predetermined duration, a character video indicating a price of a commercial item and/or a character video indicating a contact address used to purchase that item is detected from a video of the section (ST106). The continuous display time duration of the character video is detected (ST110).
