720p is a progressive scan with 720 lines of resolution.
1080i is interlaced with 1080 lines of resolution.
1080p is progressive scan with 1080 lines of resolution.
In terms of which is the better picture quality, generally you can assume that the higher the the lines of resolution, the better the picture quality.
How much of an improvement does HDTV provide over DTV/EDTV? The best answer to this question is to walk or drive to your local electronics store and get a demonstration from someone qualified to show you. You may want to have the demonstrator find channels that are broadcasting only in 480p, flip to a 720p or 1080i broadcast. On smaller televisions, you may not notice a huge difference, but it will be noticable. On larger television sets, have them demo the same 480p, to a 720p or 1080i format. It should become more evident that the 720p and 1080i broadcasts are much more sharper and clearer than the 480p format. |
We bought a
HDTV a few months ago. I spent a lot of time trying to decide which one had the better picture. If I was going to invest that kind of money into a television, I wanted to make sure it was what I wanted. I ended up choosing a LG brand 1080p. However, when I got it home and hooked up it was not the same quality of picture. Well, I thought maybe I just needed help with the settings. No, that wasn't the problem. The store conveniently forgot to tell me I had to have a
HD box,
HDMI cables, etc. O.k. I was frustrated at this point, since the whole reason I bought the t.v. was because of the crystal clear picture I saw in the store. I ended up having to also order
HD programming, as well. I didn't appreciate having to spend all this extra money to get the picture that was advertised in the store.
In addition to all this, when Direct TV came out to install the
HD box and
HDMI cables they told me that stations only broadcast in 1080i, not 1080p. He said they were selling television capable of broadcasting in a higher resolution than the stations were currently set up to broadcast.. Well, in a way I guess it could be a good thing. Hopefully, my television will be good for years to come. I asked why the picture in the store was able to broadcast 1080p, if I couldn't get it. They told me they stores play a video on a Blue-Ray in a loop. Of course, they are nature videos and the clarity is amazing. I just wish they would have told me up front what I would have to go thru to get the picture I thought I was paying for.
