I remember hearing about a method by which one could connect
directly to the composite video of an ordinary TV. Does anyone
know how this is done? I believe I have found the correct point
on the schematic of my 12" B/W TV. I think there is an issue with
isolation, since the TV ground is the AC cold (black wire). Can I
simply use capacitors? How about linear optocoupling? The
application is to bypass the RF stuff of my home computer, i.e.
connect the computer composite video directly into the TV. Thanks
in advance.
