Towards Total Integration: Broadcast, Computing & NetworkingJim DeRoest, Director Streaming Media Technologies
Total Integration • Broadcast, Computing & Networking • Broadcast Environment • Digital Instantiation - Encoding • Digital Asset Management & Delivery • Web Presence
Broadcast Components • Tape Library • Flexicart Robotics, VTRs • Traffic System • Transmission metadata • Channel Automation • Control routers, switches, uplink
Traffic System • Broadcast Metadata Management • Myers ProTrack • http://www.myersinfosys.com • Transmission list management • Tape Library Information & Support • Program/Series Title/Description/Classification • Timing to Frame • Broadcast Log/Reports/Ratings • Rights Tracking • Promotion/Underwriting Spots
Traffic System • ProTrack platform Issues • SCO and Linux • OS support • Informix DB • No External Interface – ODBC, COM • Integrating backups
Channel Automation • Harris Louth • http://www.broadcast.harris.com • Controls master control room equipment • Flexicarts, vtrs, switchers, routers, character/bug generators • Frame accurate control of devices • Backend infrastructure – source for multiple channels • Separate transmission lists: ResearchChannel, UWTV, UW2 • LAN attached “Air Clients” provide live control • Translators for traffic systems like ProTrack • Harris ADC binary format
Digital Instantiation • Injestion • Tapes Received • Dub copy for broadcast tape library • Tape metadata stored in ProTrack • MPEG2 encode • Transcode to other formats • FlipFactory • Archive digital assets
Digital Asset Management & Delivery • DigitalWell Project • http://www.digitalwell.org • Original focus broadcast environment • ResearchChannel, UWTV, KEXP • Streamline and scale asset management & delivery • Support commodity to high def bit rates • Focus expanded to institutional collections • High-quality and accessible resources to research • Educational outreach • Interoperate with other digital repositories
DigitalWell Project • Hierarchical, clustered infrastructure • Pluggable components • Tech evolution • Interoperation • API (OKI) • Metadata (Dublin Core, MPEG7, OAI) • Auth (Shibboleth) • Preservation (OAIS) • Rights • Higher education focus
DigitalWell Architecture • Hardware • Clustered/Mirrored servers NAS • Isilon Multi-node, load balancing, single mount point, DRBR • SAN Nearline Storage • STK Silos – 9840 (20GB/cart), 9940 (200GB/cart) • Software • HSM: HPSS, UW Karc (bucket service) • Metadata: MS SQL • Streaming: WM, Real, Quicktime, MP3, VideoCharger (MPEG2 5.6mbps,19.2mbps), UW HDCAM/SDTI 270mbps • UW State & Redirector
Backend Diagram • Insert diagram image - mass store system
DigitalWell Metadata • Collection and asset metadata • Dublin Core, MPEG7, Custom • Administration Tool
Putting It All Together • Integration - Web Presence • Content received • Dub master and metadata recorded (ProTrack) • Digital copies encoded and stored (DigitalWell) • VoD metadata stored (DigitalWell) • Broadcast schedule (ProTrack, Louth) • Daily extract ProTrack list metadata • Synchronize metadata (ProTrack, DigitalWell) • Tape number and program name • Dynamic generation of ResearchChannel Web • Broadcast schedule • VoD library
KEXP Radio Integration • 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
