HDTV Requires P2P
By Gary Kim, Contributing Editor
Nobody yet knows what the Federal Communications Commission ultimately will decide to do about traffic shaping. But it seems fairly clear that no matter what it decides to do, Internet Service Providers are simply going to have to make their peace with peer-to-peer applications and content streaming.
For starters, consumers, content owners and service providers are starting to recognize that video content--especially high-definition content, cannot be delivered economically any other way.
Using standard P2P techniques, HDTV content will cost application providers roughly four times more than standard definition video in 640 by 480 format (rows and columns of picture elements on a display), some would argue.
That's one reason some application and service providers are interested in managed P2P that is network aware and can assemble a P2P event using local servers to the greatest extent possible.
A standard definition, two-minute movie trailer might represent something like 47 to 78 megabytes. An HDTV version of that same movie trailer might require 126 megabytes.
A two-hour movie in standard definition might require about three gigabytes, while the HDTV version of the same two-hour movie might require 7.6 gigabytes.
