a smarter adaptive noise removal?

I think this idea has been thrown around before but here goes:

I capture alot of stuff off tv and various shows/commericals fade to/from black. When a fade reaches black, noise is at its most apparent. If spliced all together this black area might add up to 30secs of video.

Could some type of adaptive noise filter analyse this and become some type of smart filter better than what we already have? Or because noise is normally random that to the filter's it doesn't make a difference if it can have an 'only noise' sample?
