ASIS&T 2010 Building a Collaborative Testbed for Very High-Quality Media Applications Using Very High-Speed Networks April 9, 2010 Laurin Herr President, Pacific Interface Inc.
What is CineGrid? Formed 2004 – non-profit international membership organization Mission – to build an interdisciplinary community Focus – the research, development & demonstration of networked collaborative tools To enable – the production, use, preservation & exchange of very high-quality digital media over high-speed photonic networks Members – media arts schools, research universities, scientific labs, post-production facilities & hardware and software developers around the world Connected via 1 G Ethernet & 10 G Ethernet networks For – research & education
Convergence Motivates CineGrid Media technology historically driven by 3 sectors Entertainment, media, art and culture Science, medicine, education and research Military, intelligence, security and police Adoption of digital media means all 3 face converging needs Fast networking for distributed applications Access to shared devices Specialized computers and massive storage Collaboration tools for distributed teams Robust security for intellectual property Higher quality sound and picture A next generation of trained professionals

More Resolution Allows Closer Viewing of Larger Image 2. Closer Viewing of Larger Image Increases Viewing Angle 3. Increased Viewing Angle Produces Stronger Emotional Response

CineGrid Exchange TERABYTES PILING UP. To store & distribute its own collection of digital media assets. Members access materials for experiments and demonstrations. THE DIGITAL DILEMMA. Report published by AMPAS – lessons learned by NDIPP and NARA + pioneering research at Stanford (LOCKSS) & UCSD (SRB and iRODS) GLOBAL SCALE TESTBED = distributed storage + fast networks + high quality digital media assets. Explore strategic issues in digital media storage, access, distribution and preservation.
Movie-making is going digital and going global. Local talent is key! Post-production is almost all digital already. Increasingly distributed! Many movies still shot using 35mm film cameras, then scanned as the first step in the digital intermediate process, but digital cameras are getting better and better! Digital cinema projection technology is enabling better picture quality: From 2K digital to 4K digital, plus a new generation of 3D stereo movies… Avatar ! Trends in Cinema
Cinema sound quality is improving. From stereo to compressed 5.1, to uncompressed 5.1, to uncompressed 7.1 surround sound! Of the roughly 100,000 screens worldwide, only 15% are digital today. But recent financing announcements in the USA lead to forecasts that 60-70% of American screens will be digital by 2013! Fast networks are becoming critical infrastructure for media companies involved in production, post-production and distribution! Education of the next generation of media professional is critical! Trends in Cinema
Cinema Archives vs. Libraries Archive Goal: preservation without errors, access without end Access is WORSE case: Write Once Read Seldom if Ever Long-term insurance for expensive intellectual property Mixed motivations Potential for future revenue Corporate asset protection Cultural record Library Goal: customer service, active management, temporary storage Access is BEST case: Best Effort Sells Titles Mixed inventory: film, video, digital in many formats Increasing going online/near-line quicker search of inventory faster time-to-market lower cost of replication & distribution
The Digital Dilemma of Cinema 35mm film is the quality standard for motion pictures Properly stored lasts years Survives benign neglect gracefully Directly readable without reliance on software stack Very cost effective storage media 4K digital cinema needed to match 35mm analog film quality More than 8 TB per master version of 2 hour theatrical movie More than 5 million objects, ~ 2 PB total all elements per production Hollywood produce approx. 400 motion pictures per year Hollywood archives are privately funded for future profit Digital cinema preservation relying on endless migration is less reliable and much more expensive (TCO) than film preservation
CineGrid Exchange 2008 Geographically Distributed Repositories + Fast Networks San UCSD/Calit2 40 TB with 10 Gbps connectivity UvA 30 TB with 10 Gbps connectivity Keio/DMC 6 TB with 10 Gbps connectivity Total storage = 76 TB High-quality digital media assets: 4K, 2K, HD, mono & stereo, still & motion pictures + audio
CineGrid Exchange 2009 Building on Basic Concept Receive seed funding from AMPAS to start building multi-layer open source asset management & user access framework for distributed digital media repository Establish Working Group Bi-annual workshops Weekly conference calls Basecamp for online coordination Write CineGrid Exchange functional requirements document Expand CineGrid Exchange storage capacity with more nodes Diversify to reduce risk!
CineGrid Exchange 2009 Phase 1 Development Goals Define basic workflows for ingest, preservation, distribution, & deletion Implement basic workflows to automate management of collection Expand distributed repository: more nodes, more assets in collection Deploy consistently at all CineGrid Exchange nodes Enable easier large data transfers between nodes Prepare for integration of cataloging application + distributed repository Define and validate CineGrid Exchange metadata schema
