A TV camera actively scans the surface of the tube with an electron beam, 
resulting in a serial stream of data down a wire. The scanning rate and 
sequence is known (by design), allowing the CRT to "decode" the stream and 
rebuild the image. Do the light sensitive cells in the human eye respond 
to an active "scanning" system, or is the cell "dumping" its signal when a 
threshold is reached? Thanks, I've been curious for years!
