(54)Program information retrieval system and method


(57) A program information retrieval system in which a broadcast receiving terminal and a resolver server are connected through a communication network includes a local storing unit that stores a program information, a taste-information acquiring unit that acquires taste information of a user, a program-information requesting unit that requests the resolver server to provide program information, and a program-information receiving unit that receives the program information transmitted from the resolver server. The resolver server includes a master storing unit that stores the program information, a program-information-request receiving unit that receives a request for program information based on the taste information from the broadcast receiving terminal, a program-information extracting unit that extracts program information matching the taste information from the master storing unit using the identifier, and a transmitting unit that transmits the program information extracted from the master storing unit to the broadcast receiving terminal.
