I am trying to condense prior discussions and save you the usual back and forth and fail after fail after fail.
There's a lot to learn and maybe I'm going about this wrong by expecting folk to know that all this, has been done and discussed a lot. Or that folk want each answer to be vetted.
Sorry about that but I do this transfer stuff and have been through some hundred systems over the past 20 years. Not only that but I designed video capture circuitry for CCTV systems. The real circuits as in drawing the schematic, having the PCB made and integrating into the systems.
You bring up a great point as in, did the industry really mess this one up? Or was it all about Farnsworth and the best they could come up with over the past 100 years? (not kidding, read http://inventors.about.com/od/tstartinventions/a/Television.htm )
