IHDTV/DV Meeting Workshop To further the development and use of “extreme quality Internet video”.

IHDTV/DV Goals ¡ Review 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 Internetbased infrastructure for both real-time and on-demand access to such extremequality video content.

IHDTV/DV Goals ¡ Identify "missing pieces" for various classes of applications using extremequality Internet video.

Security Infrastructure and i. HDTV Categories of Applications Publishing Issues Collaboration Issues Access Management Protocol Support Internet 2 Middleware Program • Security Infrastructure and i. HDTV • First i. HDTV Workshop, January 2001 • RL "Bob" Morgan, rlmorgan@ washington. edu

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 C 15 N Bo.

Uncompressed HDTV over IP Colin Perkins, Ladan Gharai USC Information Sciences Institute Gary Goncher Tektronix

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? • 720 p: progressive, 60 fps, 1280 x 720, 20 bits/sample • 1080 i: interlaced, 30 fps, 1920 x 1080, 20 bits/sample – Resulting media stream is 1. 485 Gbps • Compare to 19. 4 Mbps compressed
