- This is an old concept... A device to filter commercials on T.V.. The problem
- is that there is NO WAY to tell when a commercial appears. We had a rather
- lengthy discussion on this news group about this idea last year. There were
- many ideas passed back and forth, but in the end, no one came up with anything
- that would work 100% of the time.
-
- The volume levels do not change during a commercial in any particular way.
- There is no "coded signal" in a commercial that identifies it as such.
- The pause between tv shows and commercials can be variable length (from as
- little as a few tenths of a second to many seconds). Therefore, you can
- simply search for a pause. (TV shows have pauses in themselves of the same
- type and length)
-
- An idea was to have a computer listen to commercials and shut off if it hears
- a commercial that was already played... Real-time computers can do this in
- less than a few tenths of a second. However, you must record the ENTIRE
- commercial onto a disk. You say, "so what? Just get a large disk drive."
- Okay, now the device has to register commercials that start in the middle
- or stop abruptly. It's just too complicated.
-
- I recommend getting cable.
