I was listening to a popular radio consumer advocate. He said that you will actually get a better picture using an antenna to get your HDTV vs. cable or satellite. The reason given was that cable and satellite have to compress the signal, but free over-the-air does not.
In the computer world, there's lossy compression, like JPEG, where some clarity is lost. Then there's ZIP where no data is lost and you receive a perfect reproduction.
So I guess their are 3 questions:
1. Is an over-the-air signal compressed or not?
2. Do cable and sattellite companies use a "lossy" compression scheme for the HDTV signals.
3. Is it true that the HDTV picture is superior if received from over-the-air transmission.
