3. Outline of Presentation Introduction of digital video libraries Introduction of the CMU Informedia Project Informedia: user perspective Informedia: technology perspective Informedia: system engineering perspective Introduction of our project How we do it Works done by us Future plans

4. Introduction of Digital Video Libraries Functions of a digital video library Why digital video libraries?

5. Functions of a Digital Video Library Storage and play back of video resources Online access of video resources Search of useful information through the vast data collections Retrieval of the most relevant selections

6. Why Digital Video Libraries? Digital signal is easy to handle in computer world Multimedia content is more interesting For education, training, sports and entertainment –dangerous chemical experiment –record of surgery process An organized way of retrieval media contents

7. CMU Informedia™ Project What is Informedia™ ? User Perspective Technology Perspective Systems Engineering Perspective

8. What is Informedia™ ? Digital Video Library Project (IDVL) By Carnegie Mellon University Begun in 1994 Leveraging two decades of related CMU research

9. Informedia: User Perspective Queries –keyboard or speech –map –similar faces Returning a set of ranked result in the form of thumbnails Retrieve and play the video clips

11. Informedia: Technology Perspective Identifying Digital Video Sizing Digital Video Scanning Through Digital Video

12. Informedia: Systems Engineering Perspective Background library creation Interactive user station Network billing server Data and network architecture

14. Introduction of Our Project Project aims How we do it? Works done by us

15. Project Aims Informedia as an existing model of DVL To develop our own version of digital video library Localization (Chinese video/scripts/queries/indexing)

16. How We Do It? Use Java Programming Language Use the Java Media Framework API Develop and test on the Windows platform

17. Why Use Java? JMF API support multimedia application Platform Independence Object-oriented language Easier to develop the GUI

18. What Can JMF Do? Enables multimedia content Supports a wide range of file formats (QuickTime, MPEG-1, MPEG-2, AVI, H.261, MIDI, AU, WAV, and AIFF) Support popular streaming media protocols

19. Works Done by Us A player which plays video clips and synchronous text scripts Mpeg videos clips of TV news Corresponding text scripts which synchronized with the video clips manually

21. Future Plans JM Editor Indexing and searching capability Auto-Indexing by Speech Recognition
