Introduced at Macworld Expo in January, Apple TV bridges the gap between your computer and your home entertainment system. The device has USB 2, Ethernet, HDMI, component video, and optical audio connections. It also supports the three most popular wireless standards: 802.11b, 802.11g, and 802.11n; thus allowing users to send content from iTunes on Mac or PC to the television.
Apple TV connects to the television via the HDMI port or using the component video connection. The wireless transmission capacity is responsible for automatically synchronizing the iTunes library from any Mac or PC, reflecting on the Apple TV any changes made to the iTunes library. You can also access and control music and photo libraries from up to five computers.
