  1. PRESTO MeetingBroadcast OPACFormat Conversion Gert Kienast Harald Mayer Sept. 19-21, 2001 BBC, London

  2. OPAC Objectives • Solution description • D3.1 Existing and Emerging Technologies • D3.2 System Specifications • Promote the use of simple ‘core metadata’ • enabling ‘core interoperability’ • based on Dublin Core, keeping native records • based on work of Scandinavian A/V metadata group • mapping of legacy and complex descriptions

  3. OPAC - Architecture

  4. OPAC Services / 1 • Search and retrieval • attribute search • find all documentaries on Bill Clinton aired in year 2000 • full text search • find everything on the PRESTO project • Browsing • lists of artists, places, topics, genres, ...

  5. OPAC Services / 2 • User registration / management • Interfaces • HTTP / HTML - simple web-interface • standardised interface • e.g. XML (supporting the MPEG-7 standard) • for application developers • system-to-system communication • Multi-language support

  6. Current Status • Interface to NZDL • Test data from BBC (1 million data sets) • Test data from ORF • Ongoing work • OPAC interface to database (Oracle, MS SQL Server) • User management / profiles

  7. OPAC Web Interface Demo

  8. Demo: Result Overview

  9. Demo: Records Retrieval

  10. Demo: Display Record

  11. Proof of Concept Environment • Platform independent • JAVA on Linux and Windows • Application Server (IBM Websphere, Enhydra) • JAVA Servlets and JSP • Data sources • NZDL; Oracle, Web services

  12. Timetable

  13. Workpackage 5 Task 5.3: Key Link Lifecycle for ‘Digital Film’ using the Concept of ‘Single Digital Master’ for Multiple Output Formats

  14. StatusFilm Format Converter • Research on State-of-the-art • Specification of Image Sequence Sampling Format (ISSF) • Specification of resampler • ISSF implementation • Resampler implementation • Time and quality evaluation • Additional Issue:Motion estimation, Occlusion detection • Ready • Ready, 3D data structure defined, SW interfaces specified • Algorithm selected, SW Spec. now • Start: begin of oct. • Start: begin of oct. • Start Nov. on sub-components • Was not planned inside Presto, but we found it is essential for proper work.If budget and progress allows we will investigate closer.
