CRC's cannot be used. They respond wildly to even a singe bit change.
Since there is always some variation in the video data, the CRC would
change with every video frame regardless of whether motion was present.


What do you mean by "will not work at all," "there is no way" and
"cannot be used"? You mean:

a) Nobody can come up with a way to use CRCs in this application, and
end up with better performance than with your proposed scheme.
b) You can't.

a or b?
