How is the color video for display on a TV generated? I have a reasonable understanding of how the composite video signal works, although probably not all the details. Each horizontal scan line consists of a lower frequency signal that represents the brightness with higher voltage being darker. Added to this is a higher frequency signal that represents color and the color is determined not by amplitude, but by phase shift relative to a reference generated during the horizontal retrace time. So, if this is how the video signal works, then to generate 16 colors, we could use one bit for a brightness level and 3 bits to select a color. I can see a D F/F to hold the brightness level during a pixel time.For color, I see an 8 bit shift register with the color signal being shifted though and an 8 to 1 multiplexer to select the phase based on the 3 color bits during each pixel time. Now add some resistors to set the right levels and maybe some capacitors to take off the sharp edges and you have a video signal. I know this is ignoring the sync signals. I am really interested in how you get color. OK, so how close am I? -chuck
