Apple TV
I have an Apple TV set up through my account. I am trying to add apps to thew tv so it will mirror my phone. it says "to access your iTunes library on apple tv turn on home sharing in iTunes on your computer using (my email).
- Home Sharing is about getting content on the Apple TV from a networked computer (its iTunes Library).
- Adding apps can be done on an Apple TV (4th generation or later), by searching the App Store on the device itself.
- AirPlay allows Screen Mirroring from a mobile device.
All these are different and independent of each other.
