CONTENT PROCESSING SYSTEM

摘要

A first information processor (100) stores identification information in a storage module (152), stores an encrypted content signal in a large-capacity storage (180), and supplies the encrypted content signal and identification information to a second information processor (200) through a communication unit (110). The first information processor (100) also stores log information generated by a purchasing module (153) of a receiver (170) each time a content key is decoded in the storage module (152) and sends the log information to a key managing center (30) through a transmitter (110) at a predetermined timing. A second information processor (200) has a communication unit (210) which receives the encrypted content signal and the identification information and a content processing section (260) which decodes the encrypted content signal and adds the identification information.
