Efficient management and promotion of utilization of the video information acquired by observation
Abstract
In Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the deep sea videos are made from the research by JAMSTEC submersibles in 1982, and the information on the huge deep-sea that will reach more 4,000 dives (ca. 24,700 tapes) by the present are opened to public via the Internet since 2002. The deep-sea videos is important because the time variation of deep-sea environment with difficult investigation and collection and growth of the living thing in extreme environment can be checked. Moreover, with development of video technique, the advanced analysis of an investigation image is attained. For grasp of deep sea environment, especially the utility value of the image is high. In JAMSTEC's Data Research Center for Marine-Earth Sciences (DrC), collection of the video are obtained by dive investigation of JAMSTEC, preservation, quality control, and open to public are performed. It is our big subject that the huge video information which utility value has expanded managed efficiently and promotion of use. In this announcement, the present measure is introduced about these subjects . The videos recorded on a tape or various media onboard are collected, and the backup and encoding for preventing the loss and degradation are performed. The video inside of a hard disk has the large file size. Then, we use the Linear Tape File System (LTFS) which attracts attention with image management engineering these days. Cost does not start compared with the usual disk backup, but correspondence years can also save the video data for a long time, and the operatively of a file is not different from a disk. The video that carried out the transcode to offer is archived by disk storage, and offer according to a use is possible for it. For the promotion of utilization of the video, the video public presentation system was reformed completely from November, 2011 to "JAMSTEC E-library of Deep Sea Images (http:// www.godac.jamstec.go.jp/jedi/)" This new system has preparing various searches (e.g. Search by map, Tree, Icon, Keyword et al.). The video annotation is enabled with the same interface, and the usability of use and management is raised. Moreover, In the "Biological Information System for Marine Life : BISMaL (http://www.godac.jamstec.go.jp/bismal/e/index.html)" which is a data system for biodiversity information, particularly in biogeographic data of marine organisms, based on photography position information, the visualization of living thing distribution, the life list of a deep sea living thing, and the deep sea video were used, and aim at the contribution to biodiversity grasp. Future, aiming at the accuracy improvement of the information given to the video by Work support of the comment registration by automatic recognition of an image and Development of a comment registration tool onboard, it aims at offering higher quality information.
