Apple TV should have a pass through HDMI connector and an app called "pass through". When the pass through app is selected ATV displays whatever is connected the the pass through - Cable box, satellite etc.
Then, this would allow us to keep the TV always on the ATV input and you wouldn't have to keep switching TV inputs when you want to airplay something from your iOS device, watch Netflix or back to regular TV for example.
