On Apple TV software 6.0 or later:
1. Use the remote control to navigate to Settings -> General -> Restrictions.
2. Scroll down to the list of apps and select which icons to hide or show.
Note: Restrictions do not have to be enabled to hide channel icons.
On earlier versions of Apple TV:
1. Use the remote control to navigate to Settings -> General -> Parental Controls.
2. Select Turn On Parental Controls and enter a four-digit passcode.
