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.
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.
Perhaps the most technically challenging conversion to make is the PAL and SÉCAM to NTSC conversion. PAL and SÉCAM use 625 lines at 50 fields/s or 25 frames/s; NTSC uses 525 lines at 59.94 fields/s (60000/1001) or 30 frames/s; The NTSC standard is temporally and spatially incompatible with both PAL and SÉCAM.
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".
NTSC and PAL image sizes are smallest, with a width of 720 (or 704) and a height of 480 or 576 lines. The third size is HDTV images that have 720 scan lines in height and are 1280 pixels wide. The largest size has 1080 lines high and 1920 pixels wide. 1080-line video is actually encoded with 1920×1088 pixel frames, but the last eight lines are ...
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.
In NTSC-system countries, the TV scan rate of 30 frame/s would cause a perceptible speedup if the same were attempted, and the necessary correction is performed by a technique called 3:2 pulldown: Over each successive pair of film frames, one is held for three video fields (1/20 of a second) and the next is held for two video fields (1/30 of a ...
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 ...
