With the rapid progress in broadband network and the launch of digital broadcasting, the environment for facilitating digital content creation and the mechanism for smoothing content distribution become increasingly indispensable. This paper addresses practical issues regarding preservation, retrieval, distribution /management, and production of digital content. It describes the architecture and the following implementations for practical usage of a large-scale digital archive: (i) A MPEG-7 based original profile and its related application software; (ii) A technique used by a remote (web-based) editing tool for referencing the original time code; and (iii) A sophisticated retrieval ID management system called "MPEG-7 over Content ID". This was constructed by combining the attribute information described by MPEG-7 with the unique code (cid) that is advocated by content ID forum (cIDf). In addition, the paper discusses how we linked our original system with cIDf compliant database aiming to protect copyright. The results of verification tests conducted at our lab showed the efficiency in content retrieval, the feasibility in creation of the required Meta data and profile during a real editing process, and the smoothness in secure content distribution.
