Furthermore, the broadcast program playback device 2 acquires a list of tag names corresponding to the portion of the broadcast program being browsed from the broadcast program management device 1, and allows the display part 23 to display it, and outputs the tag name selected by a browser from the displayed list of the tag names and the information of the broadcast time to the broadcast program management device 1. The broadcast program management device 1 returns a time range temporally adjacent to the time range in which the received broadcast time is included among the time ranges stored in association with the tag name.
