Why?

To advance global networking technologies

To explore new methods of media distribution and sharing for teaching learning and research

To further multidisciplinary multinational scientific collaboration

Because the consortium is uniquely qualified to do so


ResearchChannel is a collaboration among experts in Internet networking, storage/search infrastructure development, emerging streaming media and interactive technologies, digital television engineering, and video production.

On the Leading Edge


Projects

First Internet HDTV transmission - iHDTV

Digital Asset Management System

Development - DigitalWell

Automation of multiple format encoding

DigitalWell: HD Storage

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

• 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.

• Middleware – integrates easilyMetadata, DRM/IP, AAI, API, Grid

• Automation – End to EndCapture, Describe, Preserve, Deliver


SRB being layered underneath DigitalWell to allow sharing of content

Enables digital library systems to communicate using their metadata

Examples of libraries that can communicate using SRB: MIT’s DSpace, Cornell’s Fedora

Important step in being part of BIG science

Follow on goals (pending funding)Capture all HD footage to disk in SDTI / HDCam ™ and uncompressed SMPTE 292M formatsCreate Metadata engine for scientific annotationUse DigitalWell for storage and retrievalMake available to researchers worldwide as a collaborative effort

A demonstration project is underway involving several hours of video


Neptune – “a fiber optic cable to inner space”

http://www.neptune.washington.edu/pub/whats_neptune/whats_neptune.htmlGoals:• to establish a regional cabled observatory in the northeast

Pacific Ocean 2,500-km network of fiber-optic/power To be built across the Juan de Fuca tectonic plate in the northeast

Pacific Ocean • Locate between 15 and 20 experimental sites at nodes

along the cable. sites will be instrumented to interact with Sensor networks will fill in the volume between nodes Multipurpose robotic underwater vehicles will reside at depth,

recharge at nodes, and respond to events • Via the Internet, provide real-time information and

command-and-control capabilities to shore-based users.
