Interesting .... so that means the television system of Brazil shall
be called NTSC/PAL ??? NTSC because they use the NTSC b&w standard
(525 lines/etc), and PAL because the color is encoded according to
PAL standards.
This site:
http://www.mtxindia.com/An1.htm
refers to the underlying 525-line b&w standard as EIA rather than NTSC.
Also: monochrome monitors are usually quite flexible. I have an old
monochrome monitor myself which easily can sync to both 625-line CCIR
and 525-line EIA (or NTSC) video signals.

The 625-line b&w standard is called CCIR, which also is the name of a
now gone organisation: Committee Consultative Internationelle Radio
(French). CCIR is now been replaced by ITU-T.

I know -- CCIR/SECAM transmissions can be viewed as black-and-while on
a CCIR/PAL TV.

They probably do --- and such a DVD ought to be playagle on e.g. a
German "PAL" DVD player.
