Overview

• About The Video Development Initiative (ViDe)

• The ViDe Video Access Working Group– Projects– Next Steps

• Digital Rights Management Initiative

33

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

44

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

55

Why does digital video matter?• Key medium for elearning• Dramatic, compelling• Active learning medium,

engaging multiple senses

66

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

77

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

88

Video Access Strategies• Discovery and access• Object use

– Annotation– Bookmarking– Gathering into collections

• Use management– Safeguarding intellectual

property

99

Discovery and Access: Dublin Core 15 Optional, Repeatable

Elements

Enables interoperability:

Mapping

Data Sharing

Customize Use through Application Profile

MPEG-7 Example

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

1515

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

1616

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

1818

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

1919

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

2020

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

2121

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?
