->  Something about holding the first line in memory, then
->  scanning it at the same time as the second line.

 That is right. the Color Differnce signals, R-Y ande B-Y are sent
alternatly. The signals are frequenct modulated into the Subcarrier and
a delay line is used at the reciever to enable both sets of signals to
be avaialble. The use of Sequential signals effectiavely halves the
vertical resolution(Thus the 800 scan lines used by the French System
to get accecptable picture as compaired to NTSC)
Well that totaly exhauseted my SECAM knowledge. Berhpas it will tickel
some of your Brain Cells.  :-)  :-)


->  BTW, France has now banned the use of the term "e-mail"
->  throughout the government.

 I noted that from a CNN clip several days ago. Unbelievable Stupidity
to think you can FORCE people to not use one of the most Common Words in
the World.
