STORAGE MEDIUM RENTAL SYSTEM

摘要

A rental system includes a terminal apparatus, a BD player, and a server apparatus. At renting BD storing pieces of content, the terminal apparatus writes rental information including content ID identifying each piece of content, viewing status, and content key, to the user's memory card. The player plays back content when viewing status is "viewing-permitted" or "additionally-viewed", and when viewing status is "not-viewed", changes to "additionally-viewed", and plays it back. At returning BD, the terminal apparatus calculates a content rental fee when "additionally-viewed" is in the memory card, and charges the fee to the user. The terminal apparatus reads use-history information about playback of content from the memory card, internally stores it as use information, and regularly transmits the use information to the server apparatus managed by the content provider. The server apparatus calculates a content fee using the stored use information, and charges the fee to the rental agent.
