Access Strategies for Digital Video and Digital Rights Management Grace Agnew, Georgia Institute of Technology Mairéad Martin, University of Tennessee February 6, 2014
2 2 Overview About The Video Development Initiative (ViDe) The ViDe Video Access Working Group –Projects –Next Steps Digital Rights Management Initiative
3 3 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
4 4 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 www.vide.net/conferences
5 5 Why does digital video matter? Key medium for elearning Dramatic, compelling Active learning medium, engaging multiple senses
6 6 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
7 7 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
8 8 Video Access Strategies Discovery and access Object use –Annotation –Bookmarking –Gathering into collections Use management –Safeguarding intellectual property
9 9 Discovery and Access: Dublin Core 15 Optional, Repeatable Elements Enables interoperability: Mapping Data Sharing Customize Use through Application Profile
10 Dublin Core: Interoperability and Mapping Standard
11 Dublin Core: Base Standard DCDC MPEG-7 FDGC Geographic metadata DRM Structure Map (e.g. METS)
12 Use of Object: MPEG-7 Multimedia Content Description Interface
13 Standards based segmenting and collection building Standards based annotation and bookmarking Asset Management: Beyond Description: MPEG-7 and METS Man in a funny hat. Jones, Tommy. 00:27:13;7 Man with a funny moustache. Jones, Tommy. 00:27:13;7 MPEG-7 Example
14 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
15 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
16 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
17 Role of DRM-Core in DRM Process User Authentication Object Authorization DRM-Core Interoperable Permissions Edit Write, Copy, etc.
18 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
19 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
20 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
21 DRM-Core: Next Steps See ViDe website for participation in existing efforts: Video Access WG, MPEG-4 and Rights-L –www.vide.net Workshop to engage experts, stakeholders Creation of a Working Group YOUR THOUGHTS?
