Only CN/PAL is deployed today-
in other words, all N/PAL systems
in use are actually CN/PAL.

Brazil uses PAL-M (formally M/PAL, sometimes denoted
PAL-525), which has 480i scanning and PAL color
encoding with a subcarrier close to 3.58 MHz (but not
exactly that of NTSC).
Argentina, Paraguay, and Uruguay use system PAL-N
(formally N/PAL or CN/PAL, also known as PAL-3.58).
System N refers to 576i scanning with a bandwidth of
about 4.2 MHz. N/PAL has a color subcarrier frequency
close to 3.58 MHz (but not exactly the same as NTSC).
