It also expands connectivity, with HDMI 1.2, Component, Composite, S-Video, S/PDIF RCA and Stereo RCA making up the video and audio outputs, with a 10/100 Ethernet port for wired network connection and a USB port, though it's only used for Firmware upgrades when an Internet connection isn't available"
