You will have noticed that whenever ads are being run the
channel logo
is not broadcast. If someone can build a device to detect
absence of
logo and then mute the audio, that will fix the problem.


If you decode the data in the reserved lines at the top of the
frame,
there is information about the commercials.

So if there IS something to decode that makes commercials unique
(detectable), why has no aftermarket device been devised?? As we
have all
noted, the market would be huge. As one audio engineer stated,
maybe the
audio quality would suffer a bit, but I bet we could get used to
that much
easier than what we all commonly seem to go through now.


Network feeds contain the information needed by their affiliates
to
inset local commercials, along with a lot of other data. I have
looked
at it with a video waveform monitor, but I've never found an
information
on their propritary coding. I no longer work in broadcast TV, and
have
no connections to the industry, these days.

t seems that some people are actively engaged in the subject
