:'''[[wikipedia:PAL-M|PAL-M]]''' was only used in Brazil and should not be confused with PAL-60. PAL-M uses PAL encoding on NTSC channel allocations, as such the frequency of the color signal is lower than that of regular PAL, close but not the same as NTSC. As with NTSC PAL-M used a 59.94hz field rate.
;SECAM
:'''[[wikipedia:SECAM|SECAM]]''' (also written as ''' SÉCAM''' ) was developed in France for similar reasons as PAL. Unlike NTSC and PAL, which transmits a full color signal each line, SECAM alternates between two axes of the color signal, making a delay line mandatory for decoding(hence the name which translates roughly as Sequential color with memory). Also unlike NTSC and PAL this signal is frequency modulated, which makes it more robust to transmission errors. Aside from France, SECAM was used by the Soviet Union and its satellite states. For this reason SECAM is rarely found on video game consoles, most often opting to use a RGB SCART cable instead (in some cases such as the NES, the RGB signal comes from an internal PAL decoder, hence not being "pure" RGB). Rare exceptions are the [https://forums.atariage.com/topic/258613-atari-2600-secam/ French Atari 2600] and [https://www.smspower.org/forums/13939-SovietUSSRRussianMasterSystemWithNoCardSlot Soviet Sega Master System]
;MUSE
:''' [[wikipedia:Multiple sub-Nyquist sampling encoding|MUSE]]''' ('''<u>M</u>ultiple sub-Nyquist <u>S</u>ampling <u>E</u>ncoding'''), also known commercially as Hi-Vision (<u>h</u>igh definition tele<u>vision</u>) was created in Japan in the eighties where it was used for HDTV transmissions as well as laserdisc. MUSE works in a completely different manner from the above systems and was never used for any video game console, and is only mentioned here as it was still an analog system :)
