  1. Digital Asset Management Systems & Application Jim DeRoest, Director Streaming Media Technologies www.digitalwell.org

  2. Development • Original focus broadcast-streaming integration. • ResearchChannel, UWTV, KEXP • Automation: encode, ingest, metadata, schedule, deliver • Scalable standard def, high def, uncompressed streams • Support commodity bit rates and formats • Focus expanded to include institutional collections • High-quality and accessible resources to research information. • Educational outreach • Interoperate with other digital repositories • Why quality matters …

  3. Webcast and Video OnDemand Hours Viewed Increases 200% since Jan 2002 Breakout by Bandwidth

  4. Average Viewing Time Duration longer for VOD, higher bandwidths

  5. DigitalWell Project • Digital Asset Management System • Hierarchical, clustered infrastructure - Scaling • Pluggable components – Tech Evolution • Interoperation – Auth, Metadata, API • Preservation • Rights – Higher Education • http://www.digitalwell.org

  6. What We Built • Hardware • Clustered servers – encode, stream, … • NAS Online Storage • 12TB Isilon IQ • Multi-node, load balancing, single mount point • SAN Nearline Storage • STK Silos – 9840 (20GB/cart), 9940 (200GB/cart) • Mirrored architecture

  7. What We Built • Software • HSM: HPSS, UW Karc (bucket service) • Metadata: MS SQL • Web: IIS • Encoding: Flipfactory, Virage • Streaming: WM, Real, Quicktime, MP3, VideoCharger (MPEG2 5.6mbps,19.2mbps), UW HDCAM/SDTI 270mbps • Multicast: Amnis • DigitalWell State & Redirector Service

  8. Backend Diagram • Insert diagram image - mass store system

  9. Interoperability • Metadata • Dublin Core, MPEG7, Custom • OAI, possibly METS • API migration to OKI • LDAP Collection Service – LC/AMIA MIC • Access Controls • Pubcookie, Institutional Groups • Shibboleth under development • Preservation • OAIS?

  10. Application: Broadcast • ResearchChannel, UWTV • Automated Encoding • Dub time Mav70 capture 50mbps i-frame MPEG2 • Transcode farm – Flipfactory, Virage • +1300 hrs of standard def 5.6mbps MPEG2 • Broadcast Scheduling Integration • Protrack, DW metadata -> Dynamic web schedule • Integrated with DW On-Demand library • Standard def MPEG2 multicast • International rebroadcast support • http://www.researchchannel.org

  11. Application: KEXP • Digital Audio Infrastructure • Live Broadcast Stream • Uncompressed 1.4mbps • Commodity bit rates • Archived Live Broadcast • 2 weeks, all formats • Realtime Broadcast Playlist • Dynamic web update integrated with DJ console • Archived with live broadcast • http://kexp.org

  12. Institutional Collections • Agnostic to data type • Text, docs, photos, video, audio, dataset, … • Collection Admin Tool • Metadata profile support • Custom metadata • Interoperation: D-Space, ContentDM, … • Integration with Catalyst teaching tools • Available to UW campus summer qtr 2003

  13. Outreach & Collaborations • Pacific Lighthouse • CENIC, UW, I2 K20 • High quality audio/video to K20 • Content Partners: Densho, Conversations with History, Jason Project, Exploratorium, Cell Systems Initiative, ResearchChannel, KEXP • http://depts.washington.edu/paclight

  14. Collaboration • Moving Image Collections • NSDL, Library of Congress, AMIA • Video collection directory and union catalog • http://gondolin.rutgers.edu/MIC • Viewing the Future • NSDL MERIT Michigan Teachers Network • Audio Video Metadata for K12 • Multi University Research Library • Computer Science Lecture Collection • http://researchchannel.org/MURL/main.html • Convergence Consortium • CPB, PBS, education collaboration • MARS project – Metadata profile for PBS • http://mars.ischool.washington.edu
