Does the Apple TV require a Wi-Fi connection?

You will need an internet connection to use Apple TV, but it doesn’t have to be wireless. You can connect via an Ethernet cable. If you want to use AirPlay, which allows you to stream content from your iPhone, iPad, iPod Touch or Mac to your Apple TV, you will need a Wi-Fi network. For connecting the Apple TV to your HDTV, this is done with an HDMI cable.
