That would be the "Time Machine". Which is detectable when in use on any program that has motion. It drops frames. 
I don't know that you would use that for an HD signal. I guess it is possible, but I don't see the point in it. I would 
think it would be more of a buffering issue with the encoder or other devices in line.
