Research And Implementation Of Cataloging And Key Frame Extraction In Media Asset Management

Media Asset Management System is the request of broadcast and television’s digitization. It can help broadcast and television station to keep cost saving, to work efficiently and protect Media Asset undamaged. Media Asset Management System is made up of transcoding system, catalog system, key frame extraction system, review system, upload system, release system and so on. Catalogue manage is good for information ordering, information retrieving, information using and information sharing. So, Media Asset Catalogue Management System is the key to Media Asset management and the important component of Media Asset Management System. As a result, it has important meaning to design and implement Media Asset Catalogue Management System.Media Assert Management System contains several parts, for example, transcoding, catalog, key frame extraction, review, upload, download. This page is mainly on the research and implementation of the catalog and the key frame extraction. The system uses the design pattern of MVC. It increased the flexibility and reusability of the system. In the part of catalog, it uses the 15 metadata of Dublin Core to catalog the media. It ensures the normative and universal of the catalog. In the part of key frame extraction, it uses the equal time interval method. This method is simple and flexible. The users can control the number of the key frame. There are two manners to the user. One is manual way, and the other is automatic way. The catalog must be reviewed. If it is qualified, it can be upload. If not, it must be cataloged again.This page described the research background of the project first. And then it introduced the research status at home and abroad. Then it analyzed the Dublin Core and the MPEG standard. By reading a lot of relevant literature, it analyzed the existing methods of the key frame extraction, and introduced the equal time interval method. At the same time, it introduced the key technology. At last, it introduced the logical architecture, the core processes, the database design, and implement the system.
