480p is the shorthand name for a video mode. The p stands for progressive scan, i.e. non-interlaced, the 480 for a vertical resolution of 480 lines, usually with a horizontal resolution of 640 pixels and an aspect ratio of 4:3; that is standard-definition television (SDTV). The frame rate (in the interlaced case the field rate) is usually 30 or 60 hertz and can be given explicitly after the letter. It is usually used in former NTSC countries (North America, Japan) for NTSC can have 480p30 image resolution, but analogue and interlaced. With doubled temporal resolution, 480p60 is considered enhanced-definition television (EDTV). It can be transported by both major digital television formats, ATSC and DVB, 480p30 also on DVD.
