The mainstream media learns about HDTV over air. There's an article on CNN.com about use of antenna's to get local HD content. In the Los Angeles area I get the following HD (720p/1080i) channels:
- 2 PBS channels
- Tube (Music videos channel)
In addition each of these have 1-2 SD channels that have local/weather information broadcast in digital. And they all have digital program/schedule guides.
The CEA website http://www.antennaweb.org/ and forums on HDTV's were critical for me in deciding to use HDoA. Hopefully, this post helps others decide what to do. The critical thing is ofcourse distance from the antenna station and a good antenna.
