how can I build a Wireless Display/Transmitter that don't need a receiver? Answered
On my school's cafeteria there are 3 big HDTVs. What I wanna do is, at lunch time that everybody in in there, hijack the 3 tvs' signals and replace them with a funny video. (Also, later on I can use it on my own house)
I don't know if you've heard about those headphones that you put on and they catch the signal from the nearest TV so, at night when everyone else is sleeping you can listen to it without disturbing people. I was thinking about using something like that! Of course, doing the opposite. I don't know what's the 'official' name. Some people call it a 'low power transmitter' and other people call it 'Wireless Display (WiDi)'. Hopefully you'll know and if you do, please let me know.
I just want SOMETHING like the iTrip, you know? That the radio station IS the receiver so I won't have to build the actual receiver. I want to build/buy a transmitter that will adapt to my laptop or my iPhone so when I click play on a video, it will show on the nearest TV or TVs without the necessity of them having a receiver. That the actual TV, tv's signal, channel, whatever IS the receiver so I can carry it around without the necessity of putting something on the other end whenever I wanna watch something on a different TV.
I'm really hoping I made myself crystal clear and didn't confuse you. I'm also hoping you could give me your advice, or if you have a better method.
