Sorry, but I could not disagree more.

With analog TV standards the installed base of TV receivers was the sea anchor that kept things from changing quickly. NTSC color was a band-aid to keep B&W receivers working. And stereo was added so that it would not break existing TVs (BTW many stations never upgraded to stereo for local production).

When ATSC was created, the mind set was still analog. That is, the entire system had to be defined up front and once again millions of receivers were deployed that cannot be upgraded. There was no valid excuse for this approach, as we provided a road-map for the future and showed the ACATS folks how to build an extensible system.

So now, the ATSC standard is the sea anchor. They cannot even figure out how to add mobility without changing almost everything.

Modern programmable devices are evolving rapidly, WITHOUT a hardwired legacy to drag them down. Well, most programmable devices. - Vista demonstrates the problems trying to prop up a legacy system that was not built upon a solid software foundation.

The public is now growing accustomed to the notion that devices CAN be upgraded to do new things. My first generation iPhone is a perfect example - it does everything the 3G iPhone does except GPS and 3G.
