But Bob, isn't it time that you accept reality and admit that COFDM is never going to be used here in the U.S. for broadcast TV?

Like it or not, the system that the ATSC group has selected is something that we will be using for the rest of your (and my) lifetime. Learn to accept that. Your life will be less stressful and, just maybe, we won't have to listen to how great COFDM is (which, if you talk to some knowledgeable engineers, isn't nearly as great as you make it out to be, at least, not here in the U.S.).


In this age of rapid change where in just the last few weeks the speed of change in the broadcast industry has again quickened you talk of time frames for "TV" in terms of decades???

How quaint.

Every owner of content is considering new ways to sell their content via DVD and online download. Every advertiser is wondering what an ad on TV means by the end of 2006. What will be the penetration of DVR's by the end of next year, the year after that.

Today video was watched in our household for at least 5 hours by someone or another. No one watched a single ad. We watched a number of episodes of Rome that were previously recorded off HBO. We watched the news, local and national all recorded and we skipped the commercials. Some of us watched DVD's of previous TV shows given as gifts on Christmas.

Most of what we know about TV will be erased or radically changed in the next ten years. I plan on living longer than that and I expect 8-VSB will live a shorter life.

It is much harder to envision that ten years from now the US would still be saddled with 8-VSB and MPEG2 than almost any other change that will come to broadcasting.

Would love to hear the names of your "knowledgeable engineers" so that I can post their names. The laws of physics are the same here in the US as anywhere else. COFDM works as great here as anywhere.

It is used here in all WiFi except 802.11b. WiMax, Sirius, XMRadio, all digital ENG (electronic news gathering), wireless HD studio cameras and will be used in both the Qualcomm and Crown Castle national broadcast DTV services.

It is used in ANY modern wireless venture of ANY kind. And it will be used on most if not all spectrum of TV channels at auction above channel 51. It is rumored that Qualcomm also plans on using COFDM in future cell phone technology.

COFDM is used in all modulations in all countries other than the US, Canada, Mexico and S. Korea. It will be used in China.
