How does a HD Television convert analogue signal to digital?

And will the quality depend on the strength of your signal? If so and the outside aerial does not pick up a good reception what is the best solution?


Answer
HDTV's upscale analogue resolution by filling in the blank space by repeating lines, sort of like the analogue 100Hz TV's with line doublers. The quality depends just as much on signal strength as it does on a regular analogue television, but poor signal quality will be much more recognized because of the increased resolution. You can try using a better aerial and a signal amplifier, but beyond getting cable or satellite, there's not much you can do. If you have an HDTV, you should consider getting a STB that can receive digital signals. There are a lot of freeview HD stations you can get as it is and the quality of these are excellent. With digital, you either get the whole signal or you don't. No fuzzy static in between. If you're on the brink of losing the signal, it becomes blocky and freezes, but as long as you have a decent signal it will look just as perfect as if it was super strong.

Is it worth getting an upconverting DVD player to go with my HDTV?

The player itself is not that much but again does it make enough difference in picture quality? Also purchasing a good HDMI cable, like Monster, is almost as much as the player.


Answer
Yes get one most up-conversion in a TV is geared toward interlaced signals. Cables make or break a system. In this case buying a HDMI cable is counter productive. Using Component cables is advisable since we want to bypass the image processing of the TV and rely solely on the DVD player to interpolate the signal.

Best Buy has created a company to "make" their own cables, what ever the package says where it is made do not be fooled the raw components come from Venezuela. The Big box stores are not training their staff on the products they sell and anything technical from a employee should be weighed with a BS factor.

Anyone that says cables are a rip off, is a MORON and I said so.

You really need to audition cables, see if they add anything, a real audio/videophile will tell you that you must be happy with what you are getting. Try them out and if you aren't able to tell a difference then take them back.

Check any reputable dealer and they will say a good benchmark is to spend 10% on cables. I can't stand people coming out of a Big Box with a $100 DVD player and a $80 dollar cable with no understanding of what it adds (another reason to stay away from Best Buy and Circuit City).

That said if you have a smoking DVD player, I just got the newest Denon, you would be crazy to handicap it with $30 dollar interconnects.

Good cables make a system work like it should and performance cables make a smoking system even hotter.
