- Feasable, maybe. Practical, no.
-
- Not getting into the discussion of how much CPU/memory bandwidth is
- required to digitize video in "real-time" to any decent level of
- information that could be used to compare against another signal,
- I forsee no way of comparing this information against even the same
- commercial played off a video tape for instance. It is easy enough
- to compare them but the difficulty is in trying to decide if they
- are the same. There is so much noise, and other junk that gets
- digitized along with it that would be different each time (not to
- mention, just not starting the sampling at the exactly same spot
- on the waveform). There are many other problems with this idea
- as well.

- Commercials are always louder than the programs they are stuck
- in. It is what the advertisers pay for. This is intentional.
