When the fcc does make the switchover you have options. The first option is to simply go out and buy an hd set with the atsc tuner. By the was ATSC stands for advanced television standards committe. That was the committee formed to determine which digital television system we use in the US. You see analog systesm varied from country to country. The US, Japan, Canada and Mexico all used the NTSC system which stands for National television standards committe. That was the committe that had a similar problem when color was introduced. There were two proposed system, one electronic and one mechanical.
Now as we move to current day the Hdtv system has several noticeable differences.
1. Digital signal is basically a computer based signal broadcast to you. The digital signal has no ghosts, no color shifting and color fading, the signal is either perfect or it is gone.
2. You will have several sources to receive digital signals from: Satelite, cable tv, off-air broadcasts, dvd.
One thing you have to remember just because you have a digital television, doesn't guarantee that the program is in HD. A good live broadcast on HD can be as much as 7times more detailed than analog. Some tv stations had to re-do their news sets because with HD you could see how cheap looking the materials were they used.
