6. Internet Distribution
Webcast & Multicast All broadcasts are webcast 24/7, in audio and three video bandwidths (modem, dsl and cable). MPEG2 multicast at 3mpbs & DV at 30mbps. Video On Demand ResearchChannel offers a searchable database of over 1500 titles, viewable at modem, dsl, cable and MPEG2 bandwidths.

7. New Distribution Initiatives: Cable VOD
Ideally suited to VOD platform
Charter Communications agreement adds 2 million VOD subscribers
Launch first quarter 2006 with 15 titles per month
Google Video, Open Media Network
LAURIE’S NOTES
Given the wide variety of research topics we cover and the specific and in-depth nature of programs, we are ideally suited to the VOD platform. To quote Robert Ladd, Director of VOD for Charter Communications: ResearchChannel is “unique, great stuff.”
Charter Communications will launch ResearchChannel VOD in all markets where VOD is offered, approximately 2 million subscribers. Additionally, VOD discussions are ongoing with Comcast Communications (9 million digital households)
“Transport and Asset Management” agreements have been reached with TVN, one of the industry’s largest digital content aggregation, management, distribution and service companies. This agreement positions us well for 2006 VOD discussions with additional cable companies.

8. DigitalWell: Grid Enabled Digital Asset Management
Project Focus
Easy way to acquire, collect, classify, store ,deliver large collections of digital media over IP networks.
Proxy for any type of large data sets but initially focused on video and audio assets – content agnostic
Includes broadcast/Internet Integration
Exploits next generation networking to ensure high quality – Deliver Realism
Easy-to-use Web services-based interface compatible with current Web browsers and computing platforms.
Uses pluggable authentication to ensure security and control access to collections. 
Scalable architecture ensures that collections can be built, accessed, searched and shared between disparate networked communities. 
D-Lib/Data Grid Interoperation via SRB and OAI for content and metadata sharing..
Middleware – modular integration model
Metadata, DRM/IP, AAI, WSAPI, Grid
Automation – End to End
Capture, Describe, Preserve, Deliver
Positions digitalwell so that it is not a prorpietary system. Usere can use a differnet admit interface and no particular
Storage layer can be accessed in many different ways using middleware.
