  1. Now lets get some NTSC by ankhcraft · · Score: 5, Interesting

    Once someone posts how to do this with NTSC (which you'll need if you're in the U.S. like me), I'll be all over this! Anyone? Enlighten me...

    There's an X program that can transmit an MP3 to your radio by displaying pictures in certain ways. Quality's not too good, but it works. I guess it was just a matter of time before people did it with television.

    It also goes to show TEMPEST attacks are real. Your screen is transmitting what's on it in a way that's detectable over quite a distance. Shielding is worth looking at if you're doing something sensitive.

    I know he's the guy behind ffmpeg (used by most *nix media players) and the excellent qemu emulator that I use every day.
