Thanks again. Do you realize that there is 427 pixels per horizontial
line of NTSC? I have no idea where number "427" comes from when I read on
the website.
Technically, NTSC doesn't have any concept of "pixels". The rate of change
of phase is limited by the frequency band alloted for transmission of the
chrominance. The raster line is just one big long analogue waveform.
