Startup Idea : Two videos on same screen

It is a common scenario at homes that who will have the remote controller, because everyone wants to watch their own favourite show in the TV. And because there is only one tv, they have to compromise. This can be solved by making two videos stream on the same screen, both in full screen mode by using activie shutter glasses. Active shutter glasses can be modified to work with TV's capable of 240 FPS. Two groups of people will be able to watch two different videos on the same TV in full screen mode at the same time using modified active shutter glasses. The hardware in the TV already exists. All we need to do is modify the glasses (which is very easy). And then provide an app which allow the phones to act as remote controllers for the two different videos. Audio can be taken care of by converting stereo to mono.
