HD Peering – Our Next Hurdle
Today, most of the HD deployments are islands
Metcalfe’s Law
Says: the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2).
Percy’s Corollary:
Says: the value of a HD telecommunications network is proportional to the square of the
number of connected HD users of the system (n2).

HD Peering – Our Next Hurdle
Much like Fax machines in the 70’s, you need HD from island-to-island for customers adoption
IP Peering is paramount to truly realize value
Proposal: Form an “HD Connect Peering” committee for the carriers and their vendors.
Objective: work out the technical and business issues to enable HD IP Peering

Which Voice Coder?
What if Video had only “one coder”?Many of today’s portable video innovations wouldn’t exist!

Connecting The Islands
HD is possible between networks. However, conversion from one coder to another (transcoding)
between networks is required
