'''480p''' is the shorthand name for a family of video [[Display resolution|display resolutions]]. The p stands for [[progressive scan]], i.e. non-[[Interlaced video|interlaced]]. The ''480'' denotes a vertical resolution of 480 [[pixel]]s, usually with a [[Dots per inch|horizontal resolution]] of 640 [[pixel]]s and [[Fullscreen (aspect ratio)|4:3]] [[Aspect ratio (image)|aspect ratio]] ({{Nowrap|1={{resx|480 × {{Frac|4|3}}}} =}} 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility)<ref name="Knowledge Kaltura">{{cite web |title=Best Practices for Multi-Device Transcoding {{!}} Knowledge Center |url=https://knowledge.kaltura.com/best-practices-multi-device-transcoding |access-date=2016-09-12 |website=knowledge.kaltura.com}}</ref> pixels for an approximate [[16:9 aspect ratio]] ({{Nowrap|1={{resx|480 × {{Frac|16|9}}}} =}} 853.{{overline|3}}). Since a pixel count must be a whole number, in [[Graphics display resolution#WVGA (768×480)|Wide VGA]] displays it is generally rounded up to 854 to ensure inclusion of the entire image. The [[Film frame#Video frames|frames]] are displayed progressively as opposed to [[Interlaced video|interlaced]]. 480p was used for many early [[Plasma display|plasma televisions.]]<ref>{{cite web |last=AfterDawn.com |title=480p - AfterDawn: Glossary of technology terms & acronyms |url=http://www.afterdawn.com/glossary/terms/480p.cfm}}</ref><ref>{{cite web |title=Glossary - 480p |url=http://reviews.cnet.com/4520-6029_7-6300998-1.html?tag=txt |archive-url=http://arquivo.pt/wayback/20090709015004/http://reviews.cnet.com/4520-6029_7-6300998-1.html?tag=txt |archive-date=2009-07-09 |publisher=[[CNET]]}}</ref> [[Standard-definition television|Standard definition]] has always been a 4:3 aspect ratio with a pixel resolution of {{resx|720 × 480}} at 60&nbsp;Hz for [[NTSC]] regions, and 720 or {{resx|768 × 576}} for [[PAL]] regions (1024 wide for [[widescreen]] displays). However, standard definition defines a 15.7k&nbsp;Hz horizontal scanrate, which means that interlacing has to be used for those resolution modes. The lowercase letter "p" in 480p stands for progressive, so the two must not be confused.

== ATSC progressive mode standards ==
The [[ATSC standards|ATSC]] [[digital television]] standards define 480p with 640×480p (4:3) pixel resolutions, at 24, 30, or 60 frames per second. 

When 480p30 is broadcast on air, it is frame doubled then interlaced to 480i60. In case of [[24p|480p24]], it is processed using the [[Three-two pull down|3:2 pulldown]] technique to 480i60. In both cases the spatial resolution doesn't change, but the conversion to a interlaced format allows a direct digital to analog conversion for eventual broadcast on the analog television network.
