Equivalent "latitude" of DV

from Carlo Federiconi (cprf@jps.net)
In the film world, we speak of "latitude" when referring to the range of brightnesses, or stops, that it can handle with reasonable visible results. I've heard said that film has about 8 stops of latitude, while video has only about half that much. But I can never figure out how to tell the latitude of a particular video camera, short of doing some complicated waveform monitor tests that I know nothing about. So here are the questions:

What is the specification that relates to the equivalent latitude of a CCD? I'm assuming that latitude is a characteristic of the CCD itself, so is there any improvement in latitude between an analog and a digital camera with the same CCD? Do the multiple-CCD cameras provide greater latitude? Is the tape that the signal is recorded on a factor? (I assume minimal in the digital case)

Thanks for your help.
