  1. 1. Access Strategies for Digital Video and Digital Rights Management Grace Agnew, Georgia Institute of Technology Mairéad Martin, University of Tennessee June 2, 2011
  2. 2. Overview <ul><li>About The Video Development Initiative (ViDe) </li></ul><ul><li>The ViDe Video Access Working Group </li></ul><ul><ul><li>Projects </li></ul></ul><ul><ul><li>Next Steps </li></ul></ul><ul><li>Digital Rights Management Initiative </li></ul>
  3. 3. Video Development Initiative <ul><li>Founded in 1998 to promote the use of digital video in higher education </li></ul><ul><li>Working Groups: </li></ul><ul><ul><li>Videoconferencing: </li></ul></ul><ul><ul><ul><li>ViDeNet, Internet2 Commons, Videoconferencing Cookbook </li></ul></ul></ul><ul><ul><li>MPEG-4 </li></ul></ul><ul><ul><li>Data Collaboration </li></ul></ul><ul><ul><li>Video Access </li></ul></ul>
  4. 4. Managing Digital Video Content Workshop <ul><li>Co-sponsored by CNI, I2, SURA and ViDe </li></ul><ul><li>Keynote speakers: </li></ul><ul><ul><li>Cliff Lynch (CNI) </li></ul></ul><ul><ul><li>Jane Hunter (MPEG-7) </li></ul></ul><ul><li>Asset management, DC for digital video (ViDe application profile), rights metadata, OAI, digital video accessibility, MPEG-7, METS </li></ul><ul><li> </li></ul>
  5. 5. Why does digital video matter? <ul><li>Key medium for elearning </li></ul><ul><li>Dramatic, compelling </li></ul><ul><li>Active learning medium, engaging multiple senses </li></ul>
  6. 6. Why is digital video different? <ul><li>Complex requirements: Sequential medium, high bandwidth, hardware/software requirements, </li></ul><ul><li>Isolated from the educational mainstream </li></ul><ul><li>Frequently composed of multiple, synchronized channels, eg., multiple video and audio feeds </li></ul>
  7. 7.

  8. 8. Video Access Strategies <ul><li>Discovery and access </li></ul><ul><li>Object use </li></ul><ul><ul><li>Annotation </li></ul></ul><ul><ul><li>Bookmarking </li></ul></ul><ul><ul><li>Gathering into collections </li></ul></ul><ul><li>Use management </li></ul><ul><ul><li>Safeguarding intellectual property </li></ul></ul>
  9. 9. Discovery and Access: Dublin Core <ul><li>15 Optional, Repeatable Elements </li></ul><ul><li>Enables interoperability: </li></ul><ul><li>Mapping </li></ul><ul><li>Data Sharing </li></ul><ul><li>Customize Use through Application Profile </li></ul>
  10. 10. Dublin Core: Interoperability and Mapping Standard
  11. 11. Dublin Core: “Base” Standard D C MPEG-7 FDGC Geographic metadata DRM Structure Map (e.g. METS)
  12. 12. Use of Object: MPEG-7 Multimedia Content Description Interface
  13. 13. <ul><li>Standards based segmenting and collection building </li></ul><ul><li>Standards based annotation and bookmarking </li></ul>Asset Management: Beyond Description: MPEG-7 and METS <VideoSegment id=“S1”> <TextAnnotation> <FreeTextAnnotation>Man in a funny hat. </FreeTextAnnotation></TextAnnotation> <CreationMetaInformation><Creation><Creator>Jones, Tommy.</Creator></Creation></CreationMetaInformation> <MediaTime><MediaTimePoint>00:27:13;7</MediaTimePoint></MediaTime> <MediaDuration><00:10:05;3></MediaDuration> </VideoSegment> < VideoSegment id=“S2”> <TextAnnotation> <FreeTextAnnotation>Man with a funny moustache. </FreeTextAnnotation></TextAnnotation> <CreationMetaInformation><Creation><Creator>Jones, Tommy.</Creator></Creation></CreationMetaInformation> <MediaTime><MediaTimePoint>00:27:13;7</MediaTimePoint></MediaTime> <MediaDuration><00:10:05;3></MediaDuration> </VideoSegment> MPEG-7 Example
  14. 14. Managing use: DRM <ul><li>Technology to create DRM available </li></ul><ul><ul><li>Authorization, access, transport </li></ul></ul><ul><li>Multiple and competing languages to describe rights of the owner, and permissions for the user </li></ul><ul><li>Proprietary and commercial implementations </li></ul><ul><ul><li>No R&E implementations to date </li></ul></ul>
  15. 15. Digital Rights Management Initiative <ul><li>Launched at Managing Digital Video Assets </li></ul><ul><li>Rights-L listserv created; over 300 subscribers in 21 countries; participants include LoC, MPEG, rights language developers, NSF. </li></ul><ul><li>Interest in cooperative R&E effort </li></ul>
  16. 16. Next Steps <ul><li>Creation of a “DRM-Core” </li></ul><ul><ul><li>R&E Community development </li></ul></ul><ul><ul><ul><li>Libraries, universities, archives, consortia, standards bodies </li></ul></ul></ul><ul><ul><li>“Future-proofed”: interoperate with commercial and other systems </li></ul></ul><ul><ul><li>Describing but not enforcing rights </li></ul></ul>
  17. 17. Role of DRM-Core in DRM Process User Authentication Object Authorization <ul><li>DRM-Core </li></ul><ul><li>Interoperable </li></ul><ul><li>Permissions </li></ul><ul><ul><li>Edit </li></ul></ul><ul><ul><li>Write, </li></ul></ul><ul><ul><li>Copy, etc. </li></ul></ul>
  18. 18. DRM-Core Requirements <ul><li>Distributed collaboration </li></ul><ul><li>Growing distance education marketplace </li></ul><ul><li>Needs to support Fair Use </li></ul><ul><li>Granular and differential access </li></ul><ul><li>Management of derivatives </li></ul><ul><li>Support for complex licensing/contractual obligations </li></ul><ul><li>Integration with enterprise directories, digital certificate servers, and other technologies </li></ul>
  19. 19. R&E Scenario: Elearning <ul><li>A digital video lecture: </li></ul><ul><ul><li>Is limited to course registrants, </li></ul></ul><ul><ul><li>Available for three months after course completion </li></ul></ul><ul><ul><li>Leased to non-registrants for$10 per hour: lower-resolution video file </li></ul></ul>
  20. 20. R&E Scenario: Thesis Creation <ul><li>Student uses copyrighted video to illustrate thesis </li></ul><ul><li>Fair use permission allows selection of 20 second segments </li></ul><ul><li>Student creates and names component video selections </li></ul><ul><li>Thesis is shared worldwide via the Networked Digital Library of Theses & Dissertations </li></ul>
  21. 21. DRM-Core: Next Steps <ul><li>See ViDe website for participation in existing efforts: Video Access WG, MPEG-4 and Rights-L </li></ul><ul><ul><li> </li></ul></ul><ul><li>Workshop to engage experts, stakeholders </li></ul><ul><li>Creation of a Working Group </li></ul><ul><li>YOUR THOUGHTS? </li></ul>
