While many of the systems will use encryption. I think it is wrong to
characterize the next generation of compression codecs as "encryption
based." The same can be said for MPEG-2 today.
There are already many free services using H.264 in its various
flavors. The last Apple special event was webcast in the free & clear
to millions of H.264 enabled computers.
Compression codecs are agnostic to the business models they support.
Cable and DBS use encryption routinely because their platforms
support it. Broadcasters do not encrypt services that are delivered
in the clear. All of the downstream Broadcast Flag bull#*&# is about
control:
Control of the way content is consumed and paid for;
AND Control of potentially competing platforms for the delivery of
content to consumers.

This is ALREADY true for millions of first generation HD capable
monitors. HDMI has only been showing up in products for the past year.
Apparently this is not bothersome to the FCC.
