Both formats are now digital, but they still operate on either 30 or 60 FPS to support old CRT TVs.

There’s also the issue of cable TV and broadcast TV (now called ATSC, not NTSC). So, if you try to hook up an Australian game console or DVD player to an American TV via RCA cable, it might not work. While some modern TVs support both the NTSC and PAL formats, there’s a chance yours only supports one of the two.
If you’re transmitting video information with an analog cable (RCA, coaxial, SCART, s-video), your TV has to be able to decode that information. Well, it’s mostly an issue of compatibility. Digital TVs are fully capable of pushing past these limitations (specifically frame rates), but we still see NTSC and PAL in use today. The faults (or features) of NTSC and PAL are dictated mainly by how analog TVs function. Why does all of this matter now? We keep talking about analog TVs, but what about digital TVs? Why Does This Matter in the Digital Age? (Of course, this means PAL doesn’t work with black and white sets.) It has an increased resolution (625 lines), works on high-bandwidth frequencies, and is more reliable than NTSC. PAL was meant to address the problems with NTSC. Regular color TV broadcasts didn’t get to England until 1966 when the BBC solidified the PAL format. Other continents didn’t want to deal with NTSC’s unreliability and simply waited for color TV technology to get better. As a result, NTSC stuck with black and white resolution (525 lines), operates on low-bandwidth frequencies, and is generally unreliable. Most Americans already had black and white TV sets, so ensuring that color broadcasts were compatible with older TVs was a no-brainier. When the USA began broadcasting color TV in the early ’50s, the name of the game was backward compatibility. Frame rate aside, PAL is technically superior to NTSC. PAL Is Technically SuperiorĪmerican readers, don’t get too excited about your extra 4.97 frames per second. As a result of this “skipping,” 60 Hz NTSC TVs operate at 29.97 FPS, and 50 Hz PAL TVs run at 25 FPS. That is, they skip every other line on a screen to hold an image that looks consistent to the human eye. To fix this issue, analog TVs “interlace” an image. As a result, though, the picture at the top of the screen starts to fade as the CRT beams light at the bottom of the screen. Instead, they quickly beam light down from the top of a screen. These tubes aren’t like projectors-they can’t fill up a screen in one go. WikipediaĪnalog TVs use a cathode-ray tube (CRT) to beam light against the backside of a screen. Notice the evenly spaced lines in the first image. Look familiar? These are two examples of interlacing. But just because a TV operates at 60 Hz doesn’t mean it displays 60 frames per second. The refresh rate (frame rate) of an analog TV is directly proportional to its power consumption. On other continents, the standard is 50 Hz, but this difference has a bigger impact than you might expect. In North America, electrical power is generated at 60 Hz. The systems are incredibly similar, with the main difference being electrical consumption. PAL is an analog TV color system used in Europe, Australia, parts of Asia, parts of Africa, and parts of South America. Americans Use NTSC Everybody Else Uses PALĪt an elementary level, NTSC is an analog TV color system used in North America, Central America, and parts of South America.
