(e.g. 67.25 == video
carrier, 71.75 == audio carrier==> user inputs 67.25)

I took another look at the code I submitted before. The problem was
that the dboard was tuning to RF_freq instead of RF_freq + 1.75e6
(which is the center of the band for the TV spectrum). So if you change
the lines:
(success, actual_freq) = dboard.set_freq(RF_freq)
and
IF_freq = -5.75e6 - RF_freq
look at the code? Can someone else repost the code? I am very interested in this. Thanks

filter out audio component, translate the
video component and do the video demod?
Thanks

Just wondering if there's been any leaps or bounds in progress of NTSC decoding. We are still working on decoding the NTSC video signal in python. Has there been any progress in converting the MATLAB code to python?
