IHDTV/DV Meeting Workshop
To further the development and use of “extreme quality Internet video”.
IHDTV/DV GoalsReview the state-of-the-art of Internet
HDTV and DV via presentations by vendors and institutions who have active pilots or deployment plans for sending "extreme quality" video over Internet links.
IHDTV/DV Goals
Discuss the necessary "next steps" toward deployment of a robust Internet-based infrastructure for both real-time and on-demand access to such extreme-quality video content.
IHDTV/DV Goals
Identify "missing pieces" for various classes of applications using extreme-quality Internet video.

• Security Infrastructure and iHDTV• First iHDTV
Workshop, January 2001• RL "Bob" Morgan,

Publishing Security Issues• Access rights management
• who can do what operations on which resources • expressing and enforcing policy/contract requirements ... • ... at scalable cost • manual per-user/per-resource settings don't scale
• Content Protection
• enforcing access/use policy after content arrives at consumer ...
• Discovery, Contextualization
• applying user context to search/retrieval: • ... find me items about broncos (and I hate football) • ... find me copy of X that I have rights to access • recent work in IETF C15N BoF
Internet2 Middleware Initiative• Develop, promote infrastructure services for I2• networks • organized April 1999, producing "tightly-linked vapor" ... • some joint projects with Educause
• Directory projects • EduPerson schema: common HigherEd directory attributes • LDAP Recipe: promote best practice for HE LDAP deployments • Dir of Dirs: promote linked white pages directories
• HE-PKI • promote standards, adoption of PKI in HE • coordinate with US Federal PKI, state govts
• Shibboleth • inter-institutional Web access control • linking per-institution web authentication services • working with OASIS XML-Security TC on industry standards in this space • supported by IBM

Possible Next Steps Pushing the system: multi-stream server,
PC-based decoding
Interactivity: exploring latency vs. quality
Scaling the system: QoS, multicast, differentdata rates
Uncompressed HDTV over IP
Colin Perkins, Ladan GharaiUSC Information Sciences Institute
Gary GoncherTektronix
Why uncompressed HDTV?
• To avoid compression artifacts and loss– For example during editing/post-production
• To avoid latency in interactive use– MPEG encoders can add several frames worth of delay
• Because we can… :-)
• Implications– How much data?
• 720p: progressive, 60 fps, 1280x720, 20 bits/sample• 1080i: interlaced, 30 fps, 1920x1080, 20 bits/sample
– Resulting media stream is 1.485 Gbps• Compare to 19.4 Mbps compressed
Planned demonstration• Aim to demonstrate between ISI and UW, over the DARPA
