Reference Terms
3:2 Pull Down
3:2 pull down is a process where six frames are added to a film’s original 24-frames-per-
second format so that it can work within the 30 fps NTSC standard.
24P
A term for 24 full frames per second digital video progressively captured. It generally
refers to the HD format of 1920x1080, although it is also used with 1280x720 images as
well.
1080i
Refers to a picture resolution of 1920 vertical pixels by 1080 horizontal pixels. The “i”
stands for interlaced scanning. Interlaced scanning is based on the principle that the
screen shows every odd line at one scan of the screen and then all the even lines in a
second scan.
1080p
Refers to a picture resolution of 1,920 vertical pixels by 1,080 horizontal pixels. The “p”
stands for progressive scanning. This format works on the same principle as 720p; the
only difference is that in this type there are more pixels and the resolution is better.
1080psf
1080psf differs from 1080p defined previously; PSF is an acronym for “Progressive
Segmented Frame”. Like 1080p, psf is progressive, but it differs in that the data is
written as two separate “fields” (but without inter-field motion as interlaced video
carries). This provides psf with the temporal motion characteristics of progressive
video, but with the data transport ease of interlaced video. There should be no visual
difference between the display of a progressive frame communicated as 1080p, and
the same frame communicated as 1080psf.
16:9
Refers to the aspect ratio of movie screen and widescreen DTV formats used in all HDTV
(High Definition TV) and some SDTV (Standard Definition TV). The ratio is 16 arbitrary
units of width for every 9 arbitrary units of height.
4:3
The aspect ratio of traditional National Television Systems Committee (NTSC) TV
screens. The ratio refers to four units of width for every three units of height.
