Usb for apple tv
How to play some best photos/videos captured through iPhone which I had in flash drive /pen-drive in apple tv?
Apple TV takes its input from a network connection:
- through a local networked computer (Home Sharing),
- from servers on the internet; for photos that can be in iCloud Photo Library,
- AirPlay from a network connected mobile device or computer.
You can’t connect USB drives directly to Apple TV. Such media input is not supported.
You can connect a USB flash drive to iPhone, using an adapter, if you think that is convenient or your only option. Connect external storage devices to iPhone - Apple Support. Then you could AirPlay from iPhone.
Note the many TVs will also support reading from USB flash drives for photo slide shows. No iPhone or Apple TV needed.
