The above image shows the rear of the second-generation Apple TV and the ports it offers. Each of the ports is explained below, since knowing what each does will help you get the most out of your Apple TV.
- Power Adapter - This is where you plug in the Apple TV's power cord.
- HDMI port - Plug an HDMI cable in here and connect the other end to your HDTV or receiver. The Apple TV supports up to the 720p HD standard.
- Mini USB port - This USB port is designed to be used in service and technical support, not by the end user.
- Optical Audio jack - Connect an Optical Audio cable here and plug the other end into your receiver. This allows you to enjoy 5.1 surround sound even if your receiver doesn't support getting 5.1 audio via the HDMI port.
- Ethernet - If you're connecting the Apple TV to the Internet via a cable rather than WiFi, plug the Ethernet cable in here.
