[edit] Definition
Is this really accurate?
According to the Wikipedia article, EDTV has the resolutions 480p60, 576p50, 720i50, 720i60, 720p24, 720p25, 720p30
- 720p originated because the computer industry didn't want HDTV to use interlace scanning. (It clashes with digital compression and rendering.) They picked that number of scan lines because at 60 fps 720p has about the same number of pixels-per-second as 1080/30i, so the same chips and circuits could be used for both. 720i doesn't really serve any purpose by that logic. The famous "18 format chart" in the refs details all the official recommendations for DTV, and you'll see that 720i is not included, and would drive the number above 18 if you added it. I'll go look at that EDTV article. Algr 15:10, 27 April 2006 (UTC)
- This article needs to be changed, and fixed into a stub. 720i and 720p is entirely different. Interlace and Progressive Scanning Modes. I'm going to fix this. Imper1um 01:49, 21 March 2007 (UTC)
- No, 720i is not a real standard and is not broadcast or received anywhere. While such a standard is possible, it would serve no purpose given the current trends and advances in technology. Algr 02:29, 22 March 2007 (UTC)
- Actually, it is possible, used in many games (Xbox 360 games), and is fully supported by many American HDTVs. I would know, my work has 450 of them. >.< Imper1um 04:18, 23 March 2007 (UTC)
- No, that's still wrong. 720i is not a real HDTV standard used anywhere. If you can cough up a model no. for a TV that actually uses 720i as its highest resolution, I apologize. But for the time being, I will assume you are mistaken, also. RyokoYaksa 13:07, 7 August 2007 (UTC)

[edit] Wrong / out of date
There is a section on 720i on the 720p page, so it is not just an mistake that people make. Somebody should sort this out. I do not know enough on the subject to do it myself. Jason404 (talk) 15:35, 21 January 2008 (UTC)
- There is no such section. This is just misinformation repeating itself. 720i would not save any bandwidth as compared to 720p, and would cause all sorts of pointless complexity. Please post references if you have them. Algr (talk) 15:47, 21 March 2008 (UTC)
