Don't agree , if you are able to delay a frame, it is possible .
The mexican system uses two colours because the picture is double
interlaced. If you have a tripple interlace it can make RGB . The problem
here is colour flicker . Today this could be solved with frame stroe devices,
this causes of course artefacts in quick moving colours... and this makes
it all complicated .
The advantage of the described mexican colour is that it is very easy.
For example it can be recorded on a B&W vcr without any modificationes .
If you watch some old colour recordings, with its bad noisy colour, I think
the mexican system gives the better results here.
