dualing video

For my next invention I'm working on a way to create DVD's with dual audio and video. That way two people can watch different movies at the same time on the same TV. Kind of like those still pictures where one person sees a pretty young lady and the other person sees an old hag.
Each person will wear headphones with the sound track of the movie they are watching that will help them focus on the correct picture. It seems to work better when one movie is in the background area of the other but when the center of attention is in the same spot on the screen the picture with more action tend to overtake the other for some people. For phase one we are simply creating a website where the main picture on your computer is some boring video or text screen of your choice such as news headlines, spreadsheets and graphs, search engine data and the like. On a small part of the screen will be a picture in a picture of what you really want to pay attention to (such as a porn video or some secret formula calculations) the rest of the world walking by won't notice what you are watching. So now you can don your headphones and watch your x rated movies or terrorism training films at the airport while waiting for your plane and noone will be the wiser unless you make some subconcious noises or actions that give you away. I'm not ready to tell you the name of the website yet. First have to figure out how to get as many paying members as possible without giving away the secret of the technology. By the first of the year we should be able to have families watching a disney movie with their kids while at the same time watching an ball game. As long as its something the kids are not aware of or have no interest in they won't notice the other video. Just don't trade headphones.
