You and I are in clear agreement regarding the debilitating "disease"
affecting ATSC receiver deployment and innovation, but I'm not certain it
would be so easy to strangle COFDM in this same fashion. The dynamic would
likely be different in a number of ways:
1. There would be no US based standards committee to place a strangle hold
on the process. DVB would generally be the world wide standard, were North
America in the fold.
2. Without the ATSC standard to manipulate, those who would and do, strangle
OTA, would not gain traction; having little under their control to provide
cover.
3. Receivers could not be introduced into the US market with bugs installed
nor could artificial shortages be introduced. With the worldwide
availability of so many functional and relatively inexpensive receivers, the
CE/Subscription TV/Electronics Store cabal would simply loose control. This
stuff would be available everywhere.
4. Their ability to select and then control this unique and once very
fragile ATSC standard has given them the cover to nearly complete the
creation of the National Subscription Television System - NSTS. Soon known
as: No Shiite, This Stinks!
