  4. Why ShareStream? - Technical • Liability of existing Lauinger service (Cisco IPTV) • Proliferation of Apple Streaming Servers • No AuthN / AuthZ -- BIG Liability! • Not reliable • “Under someone’s desk” • No enterprise-class services

  5. Georgetown brings: Knowledge of higher ed environment Functional requirements Quality assurance / testing Real-world use case ShareStream brings: Significant capital investment Development resources Experience with streaming media and related technologies Why ShareStream LLC? • No funding available yet significant capital requirements • Vendor play - Everyone contributes

  6. High Level Requirements • Access • Authentication and Authorization • Content Management – metadata, browsing & searching, asset and collection relationships • Encoding • E-Commerce • Interfaces and Interoperability • Monitoring and statistics • Support for a large number of users • Significant Storage

  7. Intellectual Property Issues • Fair Use • TEACH Act Issues • DMCA Issues

  8. Capture, Encoding, Storing • Building Relationships with Faculty • “Scope” of content • Faculty planning • A different kind of “bandwidth” problem • C & E process (high-level)

  9. Audio Capture, Encode & Upload • iTunes • Create MP3s • Import metadata • ShareStream uploading tool • Imports metadata from iTunes • Transfers metadata to server • Sorenson • Squeeze (Hint) MP3s so they’re streamable • Upload hinted MP3s to ShareStream

  14. Several Pilots • Four Pilots to Date • Spring 2006 • ShareStream v 1.0 • Fall 2006 • ShareStream v 1.5 • Spring 2007 • ShareStream v 2.0 • Fall 2007

  15. Moving to Production / GA • New hardware (multiple servers and SAN) to support anticipated needs • Locking down addition of new features / requirements • Anticipate general availability for the campus in Fall 2008
