Clippers



I am looking for some feedback as to how everyone is handling the 
CCIR-601 component standard (SMPTE-259M) with references to signal 
levels (clipping).

In the NTSC composite world, we found ourselves pushing the envelope 
by adjusting the whites to 104 / 106 and the blacks down to between 7.5 to 3 units.
In the component world these levels equate to signal levels of up to 725 / 
730 mV and as low as 0 to -40mV.  What I get out of the SMPTE 
standard appears to suggest that video should stay between the 0 to 
700mV range.  What happened to the headroom we used to play with?  Is 
everyone following these guidelines?  Is everyone with the daVinci's 
using the hard clips or have the HP units been set up to chop it all off.

Any feedback would be appreciated
