that makes description using (Instance Identifier) in Media Instance DS. By adopting this method, we
intended to enhance possibility to realize smoother content distribution from retrieval to acquisition of
copyright information of content. For this purpose, necessary first step is to retrieve contents with retrieval
metadata attached to them using MPEG-7 description. The next is to display multiple screens of moving
pictures that show scene change points of each picture sequence to check the retrieved contents visually to
further narrow down the target content, and obtain its cid. Final step is to obtain information on copyright
and distribution of the content from 1PR database compliant to clDf by using cid as a key. Here, we adopt
feature description of only high level so user can recognize the description of content. By adopting such
content description, MPEG-7 can further provide various original information and functions to secure
interoperability of contents data.
Fig.4 shows an example of the disaster information which is embedded on the video data by watermark.
The earthquake information's are shown in the figure. Fig 5 shows the example of the index format of the
time code which is linked to the contents ID. This information shows the exact time of the disaster and time
history can exactly traced afterward. Hence much analytic research for the disaster can be done. As is
shown in Fig.5 the EDL (Editing Data Line) information by the watermark on the disaster video record.
Hence the situation of the disaster can simultaneously be observed. Fig.8 shows the overall multimedia
database tree of the disaster. Hence several informations can be retrieved visually by this information and
several scientific analyses can be done by this.
6. CONCLUSION
Here we report the large scale archive system and the application to the security database for
prevention of disaster. Mpeg-7 metadata format and the watermark method have been proposed for the
efficient indexing method for the prevention fo9r disaster. In the future, we plan to utilize the verified
MPEG-7 over Contents ID and make structure to consolidate he retrieval profile unique to YRC and to
adapt the control and management method of content and database using the method of content and
database using the method to requirement of wider content distribution world. We plant to aspire to
integrated content management that can adapt to professional need from retrieval of archived material
content, distribution and program production, and establish the system model that verifies content
distribution from the viewpoint of users. Thus, we are committed to contribute to the development of
content base industry.
