Hi,
Correct. There are certainly 525-line PAL standards.
And
it wouldn't suprise me if there wasn't a 625-line colour
system using NTSC-lke encoding.
As an aside, isn't (wasn't?) France's SECAM system broadcast with something
like 800 lines?

819, but proposed but not deployed. SECAM-L used in France was 625
lines, like PAL. Variants of SECAM were also deployed in various
Warsaw Block countries, including the DDR and some parts of Africa.
Although color resolution is lower than NTSC, overall picture quality
and relative immunity to transmission disturbances is superior to
PAL.

Well, you really do learn something new every day!
Makes sense I suppose.

Very true, Poland used SECAM until sometime in the 90's I believe when they
switched to some variant of PAL (I haven't been over there since 1985 so I
don't know the exact details).
....overall picture quality and relative immunity to

disturbances is superior to PAL.
I believe it was developed, at least in part, to overcome some of the
problems with PAL (whatever they are/were)?
But this is heading well OT....

As far as I know, System E (819 lines) was monochrome only. The French
Secam system was 625 lines.
I once saw a portable monochrome TV with 3 interlocked buttons to select
between 625 lines/5.5MHz souncs carrier offet (continental Europe), 625
lines/6MHz sounce carrier offset (UK) and 819 lines/AM sound (France). I
wish I'd managed to talk the owner out of it...
I assume there were French home computers and the like with SECAM colour
outputs. Were there ever 819-line video machines?
