Hello everyone i just bought Sharp 20in LCD TV
(Best Buy For Business - Product Detail)
It says it displays highdef at reduced 480p EDTV. Now do i have to get high definition cable to watch shows in 480p or would that not even work because most networks broadcastin 720 or 1080p. Can some help me out i am really confused?

As far as I can tell from your questions, your new TV displays 480p, although it can also display signals up to 1080p. This is normal with most TV's made today. Nowadays, 480, is the worst signal, so I have no idea why you want to watch anything in that mode. 720 is better, but 1080p (or 1080i) is the best signal possible.
Place a DVD in the player, and set it to send a 480 signal to the TV connected via a set of cables with yellow, red, and white terminals. That's similar to a 480 signal. If you connect the DVD player to the TV with a set of Component cables (blue, red, and green terminals), then you should be able to see a 720 signal. If the DVD player is one with "signal up-converting via HDMI), then you can play a DVD movie with the player and the TV connected to the HDMI ports (HDMI cable), and then you can see a 1080 signal on your TV.
What I would do if I was you was to buy a DVD player with signal up-converting via HDMI (make sure your TV has a HDMI port in the back, or side). Such a DVD player costs from $40.00 to as high as you want. Then I would buy a $29,00 or so HDMI cable. I bought one used for the X-Box player, and it works fine. Connect both the TV and the DVD player with the HDMI cable, and then go through the DVD player's settings to send the best signal possible to the TV. Play a DVD movie, and it will look real good. The free over the air (from the roof antenna) analog signals won't look very good, but any High Definition, or digital signal, will look great on the TV.
IMO:
There isn't a whole lot of reason to go from 720p to 1080p unless you're watching Blu-ray, which I haven't tested myself and need to find someway to figure out if its really going to be worth it.
Also, 1080i tends to be worse than 720p for fast action items. 720p has a faster refresh rate. So, just use that. Use component cable and you'll be totally fine.
Seriously, the upconversion just isnt worth it unless you're use HD DVD or Bluray.

What? If you believe it's so, then play a movie with the DVD set to 720 when connected to one of the newest sets, and then up-convert the same signal to 1080. Tell me if you can't tell the difference. I certainly can, and the difference can be noted on a good color screen.
And yes, I agree with you that a Blue-Ray or HD-DVD signal is great, but for the time being, a 720p, or an up-converted 1080p looks good enough for me.
In reality, there is not a clear answer, although a factor that seems to make a difference is the distance from you to the screen. Some of the factors are explained on video at You-Tube:

For about a 50" screen, you can tell if you're 8" away. Otherwise, the human eye cannot see the difference between 720p and 1080p.
1080i, imho, is inferior to 720p. Progressive video is much more fluid to the eye, and reduces eye strain. Given the choice, I would go 720p over 1080p.
When upconverting, its the scaler that is the primary issue. A good scaler will "improve" (atleast, from the perspective of the human eye) a low quality signal to a great deal. The scalers in dvd players now (like Faroudja) used to cost around $10k; now you see the same chips and tech in dvd players costing around $300 (pro lines). Is a native signal better? Absolutely. Will everyone notice? Doubt it.
Now, to the OP - EDTV is enhanced digital. You have a digital tuner, and will not need some sort of adapter to work with digital broadcasts. Your TV will always be displaying a 480p/i signal. However, it will accept video that is 720p or 1080p - it just scales it down to be displayed at 480p, a reduction in quality.
If you have a progressive scan DVD player, and you use component cables, this will be a 480p signal - and is the best video you'll get out of the TV, the highest quality, at native resolution.
Well, I can clearly tell the difference when I play a DVD with the player set at 720p, and then boost the signal to 1080p on my 42" TV. DVD players with signal up-converting can be had from around $45.00 to as high as you like.
A couple of mid-priced DVD players with signal up-converting via HDMI:
a. $169.00. Denon DVD-1740: 720p/1080i/1080p
b. $179.00. Yamaha DVD-S661: 720/1880i
All other companies, including Sony have such DVD players. I bought a Sony about 6 months ago, for $75.00 at Sears. The availability of such units makes it more difficult to Blue-Ray to corner the market, specially with folks who enjoy collecting DVD movies for them to watch any time they want, and without paying around $25.00 for a Blue-Ray DVD. Yes, Blue-Ray may be great, but one can still play a standard DVD to nearly a digital 1080p signal.

The native resolution of your TV is 1080p?
Is the 720p imaged filling the entire screen?
If so, whats happening is the player has upconverted to 720p, and then your TV is once again scaling up to 1080p. This will likely have a visible difference. This is not a difference of 720p vs 1080p, but the use of two scalers with different capabilities. Typically, the scaler in a TV will not be very good.

The TV is 1080i capable, a HDTV, Sony Bravia LCD. The same model this year is 1080p capable (can display up to 1080p). The DVD player I have (Sony) up-converts to 720p, or 1080i. All I do is to set the DVD to send a 720p, or a 1080i signal to the TV. The units I listed above do the same thing, except that one of the two up-converts to 720p, 1080i, and 1080p. The TV just receives and displays whatever signal is sent to it. Some new home receivers do the same. Some not only up-convert to 1080, but also switch from several video components, and send one signal to the TV.
Now, I can place my TV next to a friends, and i can't tell the difference between his playing a 1080p signal, and mine playing a 1080i. I just can't, but he thinks it's different.

Your video talks about 720p being better than 1080i. Again, faster refresh rate.
It depends on the signal coming in. a DVD isn't IN 1080p resolution, so upconverting can 'enhance' the signal, but you're still working with the original. Try playing Bluray on both TVs. I bet your 1080i will look worse than his 1080p then.
