[time-nuts] Measuring TV delays

[Chris Albertson]

When they broadcast "live" TV like from a sports vent I wonder if the time
code generated by the camera is preserved?  But then even if it were the
time might have been set manually to match the display on the camera
operator's cell phone.

Same for scenes with clacks in the background.  Do you trust them to be
on-time?   They might even have ben intentionally set wrong to hide the
transmit delay.
