Implementation of KDM system based on DCI

The Key Delivery Message(KDM) has been designed to deliver security parameters and usage rights between Digital Cinema content processing centers. We implement KDM system that consists of KDM server which can issue KDM to D-Cinema play server and content server which can receive a KDM request from D-Cinema play server and request KDM server to issue KDM for the D-Cinema play server. Proposed KDM system provides how it securely receives the KDM related information from mastering server, how it handles the KDM information in KDM server and content server, and how it issues KDM to D-Cinema play server.
