Q. ...just got an hdtv. It picks up some digital channels pixelized with no antenna. I have a few general antennas throughout the house. Will any of these work, or do you need a special HD or Digital antenna?


Answer
HDTV uses the same antennas as normal over the air television. The only difference is with amplified antennas, they generally require a higher quality amplifier as the cheap ones for analog television can distort the digital signal more than it improves it. Some antennas that say they're especially for HDTV may be designed to better reduce multipath interference. Your best bet is a directional outdoor antenna, but if you're getting stations even with no antenna, I'd just try one of those general antennas you already have and see what kind of results you get. The problem I had with indoor antennas was that when people walked around in the house it could make the signal go all pixelated. But like I said, if it's strong enough to where you're getting stuff with no antenna, might not be a problem for you. Start with the simplest/cheapest solution first and work your way up.

Is CABLE TV compatible with an LCD or Plasma TV?

I was at a friends home...they were connected to CABLE and the picture quality was pretty bad...However if you popped in a DVD...the picture quality was excellent



Answer
Basic cable broadcasts are analog and only around 425 interlaced lines maximum. To see a better picture, you would need either a HDTV signal, or a Satellite box. Cable companies claim to have digital boxes, but this is mostly marketing hype, because the channel are certainly not as high res as DVD, unless they are HDTV. If you are in a big city, you should be able to receive most HDTV channels with an indoor antenna. These channels will display at 480P, 720P and 1080i, all of which are equal to or better than DVD.
