Tv commercial replacement

Hello all - It has been a long time since I graced this fine forum.

Just as a thought I was wondering if anybody has done analysis on tv /sat signals to detect and replace advertisements / commercials.
I can see there are a few streaming based solutions but what I would be looking for is to perhaps develop a standalone hardware solution.

Your thoughts on the subject are welcomed..

    It's easy:

    Turn the TV off.

    Go to the internet and find the Parallax forums. (Ah, you did that already).

    Get some project(s) going that you can discuss here.

    Join in and try help out with projects other guys are doing.

    Some years later....should you happen to look up from your IDE or soldering iron...you will find that TV as we used to know it in the pre-internet days is obsolete and nobody watches it any more.

    Or at least, that is what happened to me. Not that I was ever much into TV since leaving the family home many decades ago.

    Sadly, you now have to turn your attention to blocking advertising on web sites instead....

    Heater ..I must compliment you on a very technical answer ;-)

    Ha, ha, thank you.

    Whilst I love engineering and technology I still have this old fashioned idea that technical solutions are not necessarily the answer to all our problems.

    Now, from what little I'm aware of good old television broadcasts now a days I have noticed one thing. The commercials have a lot louder audio than the program they are embedded in. It's really annoying when 'er-in-doors is watching telly quietly and all of a sudden I'm deafened by commercials for washing up liquid or diapers or whatever it is that girls need once a month or toilet cleaner.

    So one sure way to filter adds is to monitor the audio volume.

    Having said that, I have heard tell that there is sometimes some indication of commercials in the TV signal itself. I have no idea about that and it seems complex and unreliable.

    "Way back when", commercials were noted by an "all black" level for a defined amount of time in the TV signal. There used to be "commercial zappers" that detected this event and muted the audio.

    I believe that the broadcasters are more clever these days and have circumvented this.

    Yep, that's what I meant by "complex and unreliable". Those slippery buggers are endlessly looking for ways to get around your attempts to shut them out. Like the cleaning product salesmen of yore with their foot wedged in you front door. Extreme violence is probably a better solution than any technical gizzmo. But where to find them?

    My area has become 100% digital now, so, a box is required for every tv and or any recording device.
    I hate to say it, but what you are suggesting is illegal in my area, you can record a show, and then fast forward, but to intercept prior would be unlawful.:frown:

    Ttailspin,
    ...what you are suggesting is illegal in my area,...
    For a minute there I thought you meant my "extreme violence" suggestion :)

    Some decades ago TV companies produced such classics as "Dr Who", "The Avenegers", "Not only...but also" (Peter Cook and Dudley Moore) and many others.

    What did they do? They reused the video tapes and otherwise lost their legacy. In the case of "Dr Who" some of these have been recovered from long lost archives in the basements of TV companies in South Africa or where ever.

    My conclusion?

    I don't care what copyright law says about anything. If you find something interesting or funny or artistic or of whatever value that you might like to see, hear or read again, or have available to your friends, then you have a moral duty to make a copy and save it.

    History shows that the "rights holders" do not care at all. Even now a million miles of movie footage is rotting in basements of rights holders, lost to the world for ever.

    Ok to cover the legality - detect the commercial / advertisements then switch to a different input for the duration of the aforementioned advertisements.

    The fine print says you can do anything you want, so long as you do so after it leaves their box...

    I am right there with you heater, but I don't know where to look for these people either. Gonna need a bigger boat to find the luxury island they are hiding on..

    I've had blah-cable, uverse, and broadcast HDTV reception.

    The commercials are different in each case and there are delays from one service to another on the same channels.

    So, there is a way, legal or not to get rid of such offensive material.

    In my free time (what's that?), I tend to watch commercial-free European re-broadcast channels or PBS when there is nothing I like on the USA content pay and pay system.

    I'm quite happy with OTA Digital TV in the Bay Area now. All those retro channels not available on cable, etc... are a blast. Have you seen Hogan's Heros lately?

    I'm with Heater on this one. Turn it off. If there happens to be something worth watching on TV, it will also soon be available on the net - AdBlock works nicely. We gave up TV years ago, well, there were one or two shows that we would watch but the days of the TV just being on for extended periods are long behind us. We don't have cable or satellite but there is an antenna that I am supposed to be installing to get some OTA channels. I'm in no hurry.

    My parents watch TV nearly constantly. Once in a while I catch Jeopardy while I am visiting, then I really see how much I don't know about current celebrities and trivia.

    On behalf of my fellow members in SAG/AFTRA, please watch more TV and go to more movies! :)

    Sorry Jonny, Rick and others...

    But like I said, I still watch plenty of good shows and movies. I wish there was not so much garbage on TV is my main point, but since there is, I don't watch it.

    I dumped cable/air TV years ago.. I don't miss it. Even more I don't miss the commercials.

    @Jon, I still watch movies and even go to the theater when there is something worth paying the "big screen" for. (It's getting more and more difficult to justify more than a handful of movies a year.)

    As far as a project is concerned, aren't most commericials aired on a timed sequence?
    Seems you could combine a RTC check with a light sensor and probably make a reasonable educated guess on if it was a commecial.
    How do the DVR's do it?

    There use to be a few deices in electronics magazines that would react to increases in volume during a commercial and then do whatever you want. I watch very limited TV but usually switch to the web during commercials.

    I wonder if anyone has used a camera , a database and some face recognition software to identify commercials. time it out , do whatever and switch it back. It could work but you would have to train it for each commercial. LOL

    Bob - the volume idea is a non runner. I have read loads on this. What I'm looking for here is something similar to how a DVR cuts out ads and concatenates the pieces of the program. Use this recognition process to identify the advertisements then switch inputs for the duration and revert back.

    The suggestion to 'not watch tv' obviously doesn't answer my question.

    I fully support your attempts to build a TV ad circumvention device.

    After all, in the months and years you might spend researching, building, experimenting with such a gadget you won't have any time to actually watch TV:)

    There is software for capture cards, you connect it to AV OUT of your TV set, it detects the absence of channel logo, and based on this, presses the "mute" button or does any other predefined action. It is quite old, at least 10 year as I remember.

    Twenty years ago a friend had a video recorder that was programmed to record programs but pause recording for the videos.

    It used the fact that identifier codes for the commercials were at the beginning and end of the splice. Needless to say this invention never made it to the marketplace in any appreciable numbers before being quashed.
