영문요약	A. Decision regarding the error detection (film, tape based analog error) candidate and related algorithm development 1) Research activity investigation for error type and detection in domestic/international project. - Investigation of research activity/result of KBS (Korea), BRAVA (European Union), and AVAA(USA), related to conversion error, is served as the basis for this project - Grasp the present state of automatic quality checking products internationally, and investigate the error type generated by these products. 2) Analyze the error type statistics and patterns of the film/tapes, possessed by National Archives (NA). - We have 6347 archived movie films, and 8969 videos which NA gave to us. We perform audio visual inspection by sampling with respect to the 15,458 cases. Manual checking is performed by base technologies while automatic checking is performed by base technologies which analyze the error statistics. - We also acquired opinions from specialist through discussions about error statistics analysis found in NA. Screening is performed for already developed error detection algorithm on this basis and used as reference for drawing future road map. 3) Development of analog error detection algorithms by considering occurrence frequency in the archives (more than two algorithms) - We have developed and verified Blotch (which has highest occurrence frequencies), Betacam dropout, and Chroma noise detection algorithms. Automatic detection plug-ins is applied for each of these errors. - About automatic detection plug-in, we check the detection speed and detection rate as using NA media, and proceed with the TTA certification process. - We also submit a patent about blotch detection algorithm, and published in domestic academic conference. Betacam detection method is submitted in Electronics Letters journal (SCI). B. Implement an integrated system with digital file based quality checking links. 1) Develop quality inspection technology for real-time quality checking ingest procedure. - By distributing the output SDI signal from a VCR which is used in ingest procedure, we construct the test system which can be able to test the quality in real-time. 2) Linking Block, Block stripe, Freeze frame and video quality checking to MAM. - Construct quality inspection and test system-based solutions of digital file-based video. Then the management of quality checking is automatically connected with the MAM, the archived media management system deployed in NA. 3) Linking audio attack, clipping, mute and audio quality examination function to MAM - Construct quality inspection and test system-based solutions of digital file-based audio. Then the management of quality examination is automatically connected with the MAM, the archived media management system deployed in NA. C. Implement the development technology test-bed and on-site business feasibility test. 1) Test bed implementation as a prototype, and verify possible work applicability on field service. - such as SAN in NA, including completion of the construction of the test bed for network support environment, and further verify the automatic quality inspection system accordingly to manage the archive medias. D. Propose the way of linking the prototype to video/audio auto-restoration system - Analyze the auto-restoration system of digital video/audio; we propose the possible ways of merging with automatic quality inspection system.
