The first was the American NTSC ( National Television Systems Committee ) color television system.

* The NTSC color broadcast system was engineered by RCA to be backward compatible with black-and-white NTSC television sets.

Although color gamut can be expressed as three pairs of numbers, the XY coordinates within color space of the reddest red, greenest green, and bluest blue, it is usually expressed as a ratio of the total area within color space that a display can show relative to some standard such as saying that a display was " 120 % of NTSC ".

Originally, for NTSC countries, the seal was a large, black and gold circular starburst.

The first NTSC standard was developed in 1941 and had no provision for color television.

In 1953 a second modified version of the NTSC standard was adopted, which allowed color television broadcasting compatible with the existing stock of black-and-white receivers.

NTSC was the first widely adopted broadcast color system and remained dominant where it had been adopted until the first decade of the 21st century, when it was replaced with digital ATSC.

CBS rescinded its system in March 1953, and the FCC replaced it on December 17, 1953 with the NTSC color standard, which was cooperatively developed by several companies, including RCA and Philco.

The first publicly announced network television broadcast of a program using the NTSC " compatible color " system was an episode of NBC's Kukla, Fran and Ollie on August 30, 1953, although it was viewable in color only at the network's headquarters.

The first color NTSC television camera was the RCA TK-40, used for experimental broadcasts in 1953 ; an improved version, the TK-40A, introduced in March 1954, was the first commercially available color television camera.

The support of overscan, interlacing and genlocking capabilities, and the fact that the display timing was very close to broadcast standards ( NTSC or PAL ), made the Amiga the first ideal computer for video purposes, and indeed, it was used in many studios for digitizing video data ( sometimes called frame-grabbing ), subtitling and interactive video news.

The joke was that " SECAM " stood for " Something exceedingly Contrary to the American Method " versus NTSC " Never Twice the Same Color " whilst " Peace At Last " or " Perfection At Last " could only be obtained through the PAL system.

In the case of modern television receivers, no other technique was able to produce the precise bandpass characteristic needed for vestigial sideband reception, similar to that used in the NTSC system approved by the U. S. Federal Communications Commission ( FCC ) in 1953, and the PAL system approved by the BBC in 1957.

The use of film rather than videotape was essential, as British 405-line video was technically incompatible with the U. S. NTSC videotape format.

One advantage to using monochrome video is that different colour broadcast standards ( e. g. PAL, NTSC ) simply weren't an issue when the system was sold outside the UK.

This interlaced field rate was developed separately by Farnsworth and Zworykin in 1934, and was part of the NTSC television standards mandated by the FCC in 1941.

When NTSC color was introduced in 1953, the older rate of 60 fields per second was reduced by a factor of 1000 / 1001 to avoid interference between the chroma subcarrier and the broadcast sound carrier.

By convention an NTSC video frame is considered to start with an even field followed by an odd field.

For example, regular VHS machines sold in Australia and Europe nowadays can typically handle PAL, MESECAM for record and playback, plus NTSC for playback only ( provided the TV is able to display NTSC's 525 / 30 line standard-most can ).

Sold in the North American and Japanese consumer markets, the Nomad was never officially released in PAL territories such as Europe and Australia, though the unit retained its PAL / NTSC switch on the internal board.

In the theater it is 24 frames per second, in NTSC ( US ) Television it is 30 frames per second ( 29. 97 to be exact ), in PAL ( Europe ) television it is 25 frames per second.

Later, Europe and the rest of the world either chose between the later PAL and SECAM color television standards, or adopted NTSC.

* The unrated version, available in the US and mainland Europe, running 156 minutes ( NTSC ) and 150 minutes ( PAL ), is the most widely seen cut of the film.

The Europe / Australia version boots in PAL mode, while the others boot in NTSC mode.

While teletext is widespread in Europe and is closely associated with the PAL television system worldwide, it was is nonexistent in North America in the analog age, where the NTSC standard was used.

Most games designated as part of this region will not run on hardware designated as part of the NTSC-US, PAL ( or PAL-E, " E " stands for Europe ) or NTSC-C ( for China ) mostly due to the regional differences of the PAL ( SECAM was also used in the early 90s ) and NTSC standards.

Formula One 04 was released in Europe ( PAL ) and Japan ( NTSC ).

DVDs of region 1 ( US, NTSC format ) or region 2 ( Europe, PAL format ) can be also found in local shops like HMV ), which is not an issue for the local market as DVD players commonly sold in the shops are multi-region.

This is because switchers and effect mixers can easily handle PAL ( or NTSC ) but the SECAM-signal can't be mixed in the same way due to the frequency modulation of the color information.

352x240 and 352x288 ( or SIF ) resolution was chosen because it is half the vertical, and half the horizontal resolution of NTSC and PAL video, respectively.

Broadcast television requires 6 MHz wide channels, because it transmits 25 or 30 picture frames per second ( in the NTSC, PAL or SECAM color systems ), but SSTV usually only takes up to a maximum of 3 kHz of bandwidth.

This was possible because unlike a VHS Hi-Fi deck, an NTSC Betamax didn't need an extra pair of heads.

This is because the " 30frame / s " framerate of NTSC is actually 30 / 100. 1 %, also referred to as 29. 97frame / s – this framerate is matched when video at 23. 976frame / s has a 3: 2 pulldown applied.

Today's copies of the episode are taken from an NTSC copy returned from Canada, after the original PAL videotape was deliberately wiped by Yorkshire Television because of the offence caused.

In the original MOD file the minimum time frame was 0. 02 seconds, or a " vertical blanking " ( VSync ) interval, because the original software used the VSync timing of the monitor running at 50 Hz ( for PAL ) or 60 Hz ( for NTSC ) for timing.

NTSC vectorscopes have one set of boxes for the color bars, while their PAL counterparts have two sets of boxes, because the R-Y chrominance component in PAL reverses in phase on alternating lines.

* The UK ( Region 2 ) 18 certificate version of Freeway is 98 minutes long versus the 102 minute US ( Region 1 ) R-rated version and thus is mistakenly thought to be cut, whereas the time difference is because of normal NTSC to PAL conversion.

It is so named because of the PAL television standard traditionally used in those regions, as opposed to the NTSC standard traditionally used in the United States and Japan, which both produce a large portion of the world's televisions.

( retitled as The Jungle ) is set in a blue forest — because the game ROMs are NTSC versions played on a PAL console.

480i is usually used in countries that conventionally use NTSC ( most of the Americas and Japan ), because the 525 transmitted lines at 60 hertz of analogue NTSC contain 480 visible ones.

Many movie enthusiasts prefer PAL over NTSC despite the former's speed-up, because the latter results in telecine judder, a visual distortion not present in PAL sped-up video.

This was because, unlike 1 inch type C which recorded one field per helical scan track on the tape, Type B segmented each field to 5 or 6 tracks per field according to whether it was a 525 ( NTSC ) or 625 ( PAL ) line machine.
