* 8 - Mainly for distant transportation venues in international skies and waters such as airplanes and cruise ships, though many of these just use the format and player type of the nation they serve the most.
Note that the DVD region coding also applies to [[
For [[Blu

*** The [[Nintendo 3DS]] has introduced Region Lock on cartridge games, [[Insane Troll Logic|in hopes of combating piracy]].
** Strangely for home consoles, all PS3 games are region-free, and Xbox 360 region locking has always been at game publishers' discretion.
*** It should be noted that the [[PlayStation 3]] is a strange case. It was originally to feature optional region coding itself, using two different possible methods- the first was by Blu-Ray regional codes and the second more precise method is to query the model number of the [[PlayStation 3]]- CECHx-yy for the original models where yy is the region code, and CECH-2xyyz for the slim models, where yy is the region code. In fact, the [[PlayStation 3]] still have the region coding mechanism intact (which it still uses on Blu Ray and DVD movies, as well as [[
* In the analog age, differing TV (and electrical) standards were used as a sort of de facto regional lock-in technology. Since NTSC (typically 60Hz) and PAL/SECAM (typically 50Hz) <ref>PAL and SECAM are also different systems. And well, as noted below, it gets more complicated</ref> hardware are completely incapable of dealing with content from the other system without absurdly expensive translation hardware, this kept import trade to a minimum. Many newer PAL/SECAM TVs now offer a special 60Hz mode, and nearly every PC TV tuner/AV accessory has always supported all three standards. If all you've got are American TVs and set-top receivers, you're still hosed, though, unless you have a fairly expensive NTSC/PAL television.
** It gets even more complicated. PAL, SECAM and NTSC are only ''color'' encoding standards (though they typically have a refresh rate attached, the refresh rate is actually ''optional''. That's why there's bastard systems like 60Hz PAL and 50Hz NTSC). Ever wonder what are those letter suffixes that follows a system name when you look at the technical specifications page of a world multi TV manual? That's the ''transmission'' standard, which goes all the way from System A to System S. This is really where the TV resolution, refresh rate, and audio-visual frequency offset is defined. It's possible to mix and match transmission standard and color encoding standards, though PAL typically use B, D, E, G, H, I, K, M, N and NC, NTSC typically use M (though Japan's system could be arguably called NTSC-M'(M-prime) due to the slight luminance rating difference), and SECAM typically use B, D, G, H, K, K'(K-Prime) and L. And that's not counting abandoned systems like System A (which went through a brief trial period with all three color encoding standards by the BBC in the late 40s), and System S. Wait, there's more! This has nothing to do the the PAL, NTSC-J, NTSC/UC, NTSC-K and NTSC-C standards used for region locking game consoles. The latter bunch of imaginary NTSC variants were drummed up by marketroids to state what region code a game is for! You don't have to get confused tho- these don't really come into play as far as line input is concerned- only resolution and refresh rate are really important here with line input, and these systems should fall out of use as countries switch over to digital. On the other hand...
