The DVD version often uses a 16:9 ratio, thus carrying additional picture info on either side. —The preceding unsigned comment was added by Lee M ( talk • contribs).
While there are a number of LCD monitors sold with 852x480 resolution, the actual digital television signal format for 480p is 720x480. Noclip- do you have any source that shows 480p has a resolution of 852x480? Tvaughan1 14:39, 25 October 2006 (UTC)
When describing the display resolution we should only use active picture area. I think some of these higher figures for pixel resolution include the horizontal blanking interval. ATSC only allows 720x480, 704x480, or 640x480 (square sampling), although the latter is not commonly used anywhere. Tvaughan1 02:30, 26 October 2006 (UTC)
From what I have tested, Widescreen Anamorphic Film DVD is encoded at 720X480 and then stretched to 853x480.
If 16:9 = 1.777...
Then I would think 853x480 would be the most accurate resolution for widescreen 480p
853x480 = 1.77708333...
854x480 = 1.7791666...
852x480 = 1.775
It just so happens that most EDTVs (plasma) have a native resolution of 853x480.
Also, my understanding of Frame Rate and Refresh Rate is that you have to divide by 1.001 for accurate figures.
24 FPS = 23.976 FPS
30 FPS = 29.97 FPS
60 FPS = 59.94 FPS
48 Hz = 47.952 Hz
60 Hz = 59.94 Hz
72 Hz = 71.928 Hz
120 Hz = 119.8801 Hz
Does the 480p standard prescribe square or rectangular pixels for the image? Perhaps this should be tossed in the article. Daniel.Cardenas 20:19, 10 June 2007 (UTC)
{{ helpme}} I don't think the line "The 480 denotes a vertical resolution of 480 vertically scanning lines" is correct. 480 pixels vertical resolution (or "480 pixels tall", as described by http://www.afterdawn.com/glossary/terms/480p.cfm) should be equivalent to 480 horizontally scanning lines instead. Am I right? Stephanas ( talk) 20:56, 6 February 2010 (UTC)
This statement is not correct unless qualified: "Standard definition has always been a 4:3 aspect ratio with a pixel resolution of 640 × 480 pixels."
In DVB, standard definition has always been 576i, displaying as 1024 x 576, aspect ration 16:9.
Please state in what domain SD has always been 4:3. (I've never heard this idea before.) — Preceding unsigned comment added by 59.101.113.26 ( talk) 03:21, 5 July 2015 (UTC)
AlgebraFanatic8 has added many unannoteted entries to the table. Where do these come from? Why are they relevant? ~ Kvng ( talk) 16:05, 31 January 2024 (UTC)
