Searching a data base

摘要

A play list comprising the names of music pieces broadcasted from a broadcast station and broadcast time information are accumulated in a data base. If a user likes a music piece broadcasted from the broadcast station, he activates a book marker which stores time information representing the time at which the book marker is activated. The time information is supplied through a gateway device to a search engine which searches the data base for those broadcast stations in the user's geographic area which broadcasted music pieces or the like at a time that matches the time information. The search results are transmitted to the gateway device and displayed.
