Storage apparatus, method for validating encrypted content and terminal apparatus |
摘要 |
A user can watch desired content among a plurality of encrypted contents recorded in a storage apparatus having a large capacity recording medium when the user wants to watch. Usage Pass (UP) necessary for watching content and encrypted content are recorded in a rental storage apparatus. The UP is in an invalid state when the storage apparatus is rented, and processing for validating the corresponding UP is executed between the storage apparatus and a host apparatus through which content is watched to thereby make content watchable. A history that processing for validating the UP is executed is recorded in the storage apparatus. A service provider bills a content use fee to the user based on the history of the storage apparatus. |
