Ah alas then that scratches the headphone to TV connection idea. However there are still other alternative and perhaps viable methods such as a mini-USB2VGA connector or AV to mini-USB. My understanding is that the USB does not support host mode, however i dont know if host mode is required for our purposes.

Another alternative might be to send video via wifi(or maybe bluetooth?) wirelessly to some device connected to a TV.

Right now Im trying to figure out what the hardware allows and then go from there.
