I called Scientific Atlanta years ago, to find out if this function was possible and was told that they design the boxes to use it, but the cable providers omit that, as well as the IR input.
Aside from using a voltage sensor from an analog video out jack, there's no good way to do this unless you want to program the Crestron to send a Power On command at 5AM, or whenever they would never be awake.

It's been years since I've looked at this problem, but back then the video output became a black screen when you turned the box "off." That is, it was still outputting sync and a video signal; it's just that the screen looked like what you'd get from a box that's off: a black screen.
