After reading all of the above response posts for this thread, I'm not
really certain that you have yet received a definite reply as to how
to do the detecting of adverts on TV.
Another possibility may be for you to 'digitally' record say the 1st 5
seconds of audio for each ADVERT shown from the TV (suggest do
recording over say a 5 day period to get as many Adverts as possible
that are transmitted) - then using these 'recorded' SPOTS perform
comparison checks against the 'received' Ads from the TV service.
Also you may find that commercial TV services show Ads in sets of 4-6
Ads (or maybe more - for some) after so many minutes of actual program
shown - so blocks of Ads become more easier to detect and monitor if
you use the 'digital' audio record & comparison method. In the
majority of cases the audio of Ads doesn't change -UNLESS the Ad
changes (can be expensive for the company placing the Advert - so they
usually don't change the Ads too many times over a year unless they
can feel justified to get more public response - such as the likes of
Supermarkets [Woolworths, etc..] or higher profile companies
[airlines, travel agents, etc..] or UNLESS the TV service is
experiencing transmission problems - then all bets are out the window.
I suggest that the first 5 seconds of audio will be more than
sufficient to get a good 'digital' signature to use as the comparison
reference - you most probably find that when the system is performing
a 'comparison' the 1st 1-2 seconds of the digital reference will be
all that will be needed to determine a match.
I hope this helps!!
