Airplay question: Suppose I'd like to stream a video from the internet to my Apple TV via Airplay with my iPad being the middle man. Does the full video stream come to my iPad and then get beamed back to the Apple TV? Or is it somehow redirected to the Apple TV to save on battery, network resources, etc.?
The reason I ask is because it doesn't really seem to use up as much juice as I would expect it to. I have listened to about 30 minutes of radio and watched about 30 minutes of a documentary, and I have only used 4% of the battery. Seems too good to be true.
