  • Access Strategies for Digital Video and Digital Rights Management Grace Agnew, Georgia Institute of Technology Mairéad Martin, University of Tennessee June 2, 2011
  • Overview
    • About The Video Development Initiative (ViDe)
    • The ViDe Video Access Working Group
      • Projects
      • Next Steps
    • Digital Rights Management Initiative
  • Video Development Initiative
    • Founded in 1998 to promote the use of digital video in higher education
    • Working Groups:
      • Videoconferencing:
        • ViDeNet, Internet2 Commons, Videoconferencing Cookbook
      • MPEG-4
      • Data Collaboration
      • Video Access
  • Managing Digital Video Content Workshop
    • Co-sponsored by CNI, I2, SURA and ViDe
    • Keynote speakers:
      • Cliff Lynch (CNI)
      • Jane Hunter (MPEG-7)
    • Asset management, DC for digital video (ViDe application profile), rights metadata, OAI, digital video accessibility, MPEG-7, METS
  • Why does digital video matter?
    • Key medium for elearning
    • Dramatic, compelling
    • Active learning medium, engaging multiple senses
  • Why is digital video different?
    • Complex requirements: Sequential medium, high bandwidth, hardware/software requirements,
    • Isolated from the educational mainstream
    • Frequently composed of multiple, synchronized channels, eg., multiple video and audio feeds
  • ViDe Video Access WG
    • International membership of librarians, engineers, IT professionals
    • Collaborates with I2 and CNI
    • Projects:
      • Application Profile for Dublin Core
      • Application Profile and Advanced Indexing Strategies with MPEG-7 and METS
  • Video Access Strategies
    • Discovery and access
    • Object use
      • Annotation
      • Bookmarking
      • Gathering into collections
    • Use management
      • Safeguarding intellectual property
  • Discovery and Access: Dublin Core
    • 15 Optional, Repeatable Elements
    • Enables interoperability:
    • Mapping
    • Data Sharing
    • Customize Use through Application Profile
  • Dublin Core: Interoperability and Mapping Standard
  • Dublin Core: “Base” Standard D C MPEG-7 FDGC Geographic metadata DRM Structure Map (e.g. METS)
  • Use of Object: MPEG-7 Multimedia Content Description Interface
    • Standards based segmenting and collection building
    • Standards based annotation and bookmarking

  • Managing use: DRM
    • Technology to create DRM available
      • Authorization, access, transport
    • Multiple and competing languages to describe rights of the owner, and permissions for the user
    • Proprietary and commercial implementations
      • No R&E implementations to date
  • Digital Rights Management Initiative
    • Launched at Managing Digital Video Assets
    • Rights-L listserv created; over 300 subscribers in 21 countries; participants include LoC, MPEG, rights language developers, NSF.
    • Interest in cooperative R&E effort
  • Next Steps
    • Creation of a “DRM-Core”
      • R&E Community development
        • Libraries, universities, archives, consortia, standards bodies
      • “Future-proofed”: interoperate with commercial and other systems
      • Describing but not enforcing rights
  • Role of DRM-Core in DRM Process User Authentication Object Authorization
    • DRM-Core
    • Interoperable
    • Permissions
      • Edit
      • Write,
      • Copy, etc.
  • DRM-Core Requirements
    • Distributed collaboration
    • Growing distance education marketplace
    • Needs to support Fair Use
    • Granular and differential access
    • Management of derivatives
    • Support for complex licensing/contractual obligations
    • Integration with enterprise directories, digital certificate servers, and other technologies
  • R&E Scenario: Elearning
    • A digital video lecture:
      • Is limited to course registrants,
      • Available for three months after course completion
      • Leased to non-registrants for$10 per hour: lower-resolution video file
  • R&E Scenario: Thesis Creation
    • Student uses copyrighted video to illustrate thesis
    • Fair use permission allows selection of 20 second segments
    • Student creates and names component video selections
    • Thesis is shared worldwide via the Networked Digital Library of Theses & Dissertations
  • DRM-Core: Next Steps
    • See ViDe website for participation in existing efforts: Video Access WG, MPEG-4 and Rights-L
    • Workshop to engage experts, stakeholders
    • Creation of a Working Group
