Editing Serial digital interface (section)

===Supported video formats===
The various versions of the serial digital interface support numerous video formats:

* The 270&nbsp;Mbit/s interface supports 525-line, interlaced video at a 59.94&nbsp;Hz field rate (29.97&nbsp;Hz frame rate), and 625-line, 50&nbsp;Hz interlaced video. These formats are highly compatible with [[NTSC]] and [[PAL]]-B/G/D/K/I systems respectively; and the terms '''NTSC''' and '''PAL''' are often (incorrectly) used to refer to these formats. (PAL is a composite color encoding scheme, and the term does not define the line-standard, though it is most usually encountered with 625i) while the serial digital interface— other than the obsolete 143&nbsp;Mbit/s and 177&nbsp;Mbit/s forms- is a component standard.
* The 360&nbsp;Mbit/s interface supports 525i and 625i widescreen. It can also be used to support 525p, if 4:2:0 sampling is used.
* The various 540&nbsp;Mbit/s interfaces support 525p and 625p formats.
* The nominal 1.49&nbsp;Gbit/s interfaces support most [[high-definition video]] formats. Supported formats include 1080/60i, 1080/59.94i, 1080/50i, 1080/30p, 1080/29.97p, 1080/25p, 1080/24p, 1080/23.98p, 720/60p, 720/59.94p, and 720/50p. In addition, there are several 1035i formats (an obsolete Japanese television standard), half-bandwidth 720p standards such as 720/24p (used in some film conversion applications, and unusual because it has an odd number of samples per line{{Citation needed|date=March 2008}}), and various 1080psf (progressive, segmented frame) formats. Progressive Segmented frames formats appear as [[Interlaced video|interlace video]] but contain video which is progressively scanned. This is done to support analog monitors and televisions, many of which are incapable of locking to low field rates such as 30&nbsp;Hz and 24&nbsp;Hz.
* The 2.97&nbsp;Gbit/s dual link HD interface supports 1080/60p, 1080/59.94p, and 1080/50p, as well as 4:4:4 encoding, greater color depth, RGB encoding, alpha channels, and nonstandard resolutions (often encountered in computer graphics or [[digital cinema]]).
* A quad link interface of 3G-SDI supports UHDTV-1 resolution 2160/60p
