PAL and NTSC have slightly divergent colour spaces, but the colour decoder differences here are ignored. Outside of film and TV broadcasts, the differences between PAL and NTSC when used in the context of video games were quite dramatic. For comparison, the NTSC standard is 60 fields/30 frames per second while PAL is 50 fields/25 frames per second.
However, most NTSC players cannot play PAL discs, and most NTSC TVs do not accept 576i video signals as used on PAL/SECAM DVDs. Those in NTSC countries, such as the United States, generally require both a region-free, multi-standard player and a multi-standard television to view PAL discs, or a converter box, whereas those in PAL countries ...
Most of the DVD-based content in the country is NTSC/60 Hz-based, while the TV standard in use is PAL/50 Hz-based. Most of the analog TV sets sold are PAL-N, PAL-M and NTSC capable, while most DVD players are multi-region. Authorities are not asking retailers to identify which standard the HDTV sets sold adhere to.
The NTSC 4.43 system, while not a broadcast format, appears most often as a playback function of PAL cassette format VCRs, beginning with the Sony 3/4" U-Matic format and then following onto Betamax and VHS format machines, commonly advertised as "NTSC playback on PAL TV".
Analog television systems were standardized by the International Telecommunication Union (ITU) in 1961, [1] with each system designated by a letter (A-N) in combination with the color standard used (NTSC, PAL or SECAM) - for example PAL-B, NTSC-M, etc.). These analog systems for TV broadcasting dominated until the 2000s.
Not all of the possible combinations exist. NTSC is only used with system M, even though there were experiments with NTSC-A in the UK and NTSC-N (625 line) in part of South America. PAL is used with a variety of 625-line standards (B, G, D, K, I, N) but also with the North American 525-line standard, accordingly named PAL-M. Likewise, SECAM is ...
For viewing native PAL or SECAM material (such as European television series and some European movies) on NTSC equipment, a standards conversion has to take place. There are basically two ways to accomplish this: The framerate can be slowed from 25 to 23.976 frames per second (a slowdown of about 4%) to subsequently apply 3:2 pulldown .
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. [7] DVDLard states "the majority of authorities on the subject favour PAL over NTSC for DVD playback quality". [7] Also DVD reviewers often make mention of this cause.
