Vidmid VC Vid. Mid Video. Conferencing Chair, Egon Verharen, SURFnet Goals: • To develop set of simple, authenticated desktop vc clients, along with the associated directory and authentication components – To identify network-based infrastructure to support interrealm community video • H. 323, SIP, VRVS/AG (multicast) – To foster interoperability at the identifier, security and video stream levels – Enable authenticated and authorized call setup – Engage industry players 9/10/2020 CAMP 2002, http: //middleware. internet 2. edu/video/ 5

Vidmid Vo. D Vid. Mid Video-on-Demand Chair, Mairead Martin, The University of Tennessee Goals: • Enable effective and secure access to digitalvideo resources • Ensure judicious use of digital video resources • Coordinate with international metadata efforts • Engage industry players 9/10/2020 CAMP 2002, http: //middleware. internet 2. edu/video/ 11

Vidmid Vo. D status • Draft of Vo. D scenarios online • http: //www. ait. utk. edu/Vid. Mid/Vo. D/scenarios. html • White paper on role of directories in Vo. D • Will be included in NMI 1. 0 release (April 2002) • Exploring use of Shibboleth in Digital Rights Management. 9/10/2020 CAMP 2002, http: //middleware. internet 2. edu/video/ 12

Access to Digital Materials Digital Rights Management is about content control Several ways to use digital materials: • personal use • typically purchased by individuals on a subscription or per-use basis. • professional use • typically acquired (for fee or legal agreement) by an organization or university on a bulk basis, with access redistributed freely to members of the organization. • public use • as a citizen, entitled to an information commons, and other basic information rights, such as Fair Use and Freedom of Information 9/10/2020 CAMP 2002, http: //middleware. internet 2. edu/video/ 13

Digital rights technologies • The different uses of on-line materials have different requirements • they will likely require different technologies. • Requirements vary about the needs and controls for privacy, the economic recovery model, the needs and controls for security, etc. • e. g. ability to snip fair use clips • Who is developing the digital rights technologies for professional and public use? 9/10/2020 CAMP 2002, http: //middleware. internet 2. edu/video/ 14
