Transcript IHDTV/DV Meeting Workshop

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.

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

Possible Next Steps
 Pushing the system: multi-stream server,
PC-based decoding
 Interactivity: exploring latency vs. quality
 Scaling the system: QoS, multicast, different
data rates
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?
• 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
