Does anyone know where the A to D converters in digital video stuff
such as MiniDV, Digital8 and DVD run out of 1's and clip the signal?
Does anything bad happen when it does, such as bearding or losing sync?
This could happen with impedance mismatch, maladjusted camera clipping
point, etc.
I have seen consumer VHS machines that put out about 1.25 volts of
video. Presumably if digital machines are designed to accept this (so
the public can convert their home tapies to DVD), then this would be
about the limit. I'm just wondering how close to clipping level normal
video would be. Thanks.
