How do I turn on home sharing on my iPad

Make sure you first set up Home Sharing on a Mac/PC running iTunes.

Use Home Sharing to share iTunes content with other devices - Apple Support

Now you join home sharing from your iPad.

Hi chelseafromtoledo. Note that an iOS device is a Home Sharing client only, not a server. You cannot share files from your iOS device for access by other devices. If you want to send video to Apple TV, use AirPlay instead.
