CONTENT PROCESSING APPARATUS, AND MOVING METHOD OF THE CONTENT

摘要

PROBLEM TO BE SOLVED: To quickly return a response to a commitment request when the commitment request is given from a content receiving side to a content transmitting side when moving the content based on a DTCP-IP standard by an iVDR-capable device on an IP network.

SOLUTION: When all the encryption keys corresponding to each block stored in an HDD are transferred to a main storage device, an untransferred content is divided by number of the encryption keys. Then, each piece of the divided data is decrypted. When transferring each piece of decrypted divided data to other content processing apparatus, one of the decryption key on the HDD is deleted in response to the transfer of one piece of the divided data to the content processing apparatus.
