requirements:
EyeTV software running on a local networked Mac
get EyeTV software here http://www.elgato.com/elgato/na/mainmenu/products/software/EyeTV3/product1.en.html
a pretty powerful, fast Mac.
enable iPhone access on the EyeTV software.
i really recommend you go to the developer's page to make sure this is going to work for you. i can't explain it better because i've never used a Mac.
