Do "480p60" progressive-scan DVD players really output 59.94 frames per second (as a permanent gesture of backwards compatibility towards old TVs forever tied to 59.94 field/second NTSC), or do they literally output 60 frames per second?


Along the same lines, if current Progressive-scan DVD players DO output 59.94 frames/second, is "480p60" always going to really mean "480p59.94", or is 59.94 just a temporary transition framerate until NTSC is finally dead and buried once and for all at some point in the future?

Yes, 480p/60 is actually at 59.94Hz. It's stated as 60 for ease of reading.


I'm not sure if the frame rate changes under ATSC (i.e. is 720p/60 really 60Hz, or is it 59.94 as well). I do know that at least one scaler, the Lumagen, now has genlock capabilities to help mitigate the effects of a 60Hz/59.94Hz difference.
