Color burst zoomed in

Here is an oscilloscope view of the color burst before (green) and after (yellow) it has gone through the ADC/DAC.

It's interesting, it appears that you can see the discrete binary transitions on the DAC output. I have to admit, I thought that there would be a bit more resolution to those binary waves. Parsing that and trying to find the actual clock cadence may be tricky in software. (tricky but not impossible)
