2. Project Overview The film classroom of the future Digital distribution of video sequences Selected to support classroom instruction in film Also supports research regarding viewer responses to image capture formats and projection systems

3. Project Overview, continued Digital projection To provide large, extraordinarily high- quality images Video annotation tools for instructors “John Madden in the film classroom”

4. Digital Arts and Entertainment Laboratory Georgia State University Moving image production and research Richest image capture formats Digital video 35mm film HDTV Digital projection

5. Interactive Media Technology Center Research center at Georgia Tech Focusing on digital media processing in arts, technology, and culture.

6. What Brings us Together Internet2, literally The Georgia Research Alliance Digital Content Cluster

7. Rationale for Digital Cinema 101 Many film programs and courses at Internet2 universities Growing in popularity Both general education and discipline- specific courses Film is a rich medium But classroom instruction is visually impoverished

8. Current Instructional Materials Visually impoverished Example: Bordwell and Thompson’s Film Art McGraw-Hill Best-selling film textbook of all time

14. Current Instructional Systems Expensive, non-networked Example: PreView system Kodak and Panavision

16. Content to be Served: “Film 101” Sequences tied to Film Art textbook Color Depth of field Lighting Other cinematography issues

17. Content to be Served: Film/Video and Digital Imaging Production Sequences to demonstrate image capture formats and projection systems HD vs. 35mm film Aspect ratios Artifacts

18. Content to be Served: Research Stimuli Sequences designed to test audience responses to image capture formats and projection devices Use Internet2 to share data and subjects for moving image studies “Co-laboratory network”

19. Digital Cinema Today Disney, Lucas, Technicolor, Texas Instruments - Field Tests 31 screens in 10 countries Over 1,000,000 viewers have seen a digital movie Systems are somewhat “hacked” together, prototype equipment

20. Digital Cinema Today Source 1920x1080 pixels, 10 bits per pixel 24 progressive scanned or 60 interlaced frames/second Projected at 1280x1024 pixels 6 Channel Digital Audio Wavelet compressed

21. Technology Needs Storage Distribution Projection

22. Storage Storage requirements are enormous 135 minute movie uncompressed – 1.5 TB Star Wars Episode One was 330 GB as presented in theaters Current compression scheme is ~50 GB/movie

23. Storage Challenges Lower data rate without lowering the quality Better compression schemes designed for film, not video

24. Distribution Star Wars 1 – Technicians hand carried disk drives for drive arrays Now – Ship 7-10 DVD-ROM’s with movie loaded, copy to drive array

25. Hollywood’s Vision of Distribution Maybe satellite multicast? Maybe continue to ship DVD-ROM Biggest issue to Hollywood – Security

26. Our Vision of distribution Secure distribution via IP networks Challenges QoS Encryption Authentication Copyright protection Bandwidth

27. Projection Currently theatres are using JVC or TI projectors (most using TI DLP). Silicon Light Machines has new technology of interest also Very expensive This will be a concern for classroom use, but SXGA projectors have adequate resolution (perhaps)

28. Research Uses over I2 Medical Video Arts and Humanities ??? Let us know
