In case you're wondering, "ARC" stands for Audio Return Channel. It allows this particular input to send audio back to an AV receiver over the same HDMI cable that is carrying video from the receiver to the HDTV. That's useful if you're using your HDTV's over-the-air tuner or perhaps one of its built-in streaming media services (such as Netflix or Amazon VOD), and want to listen with your surround-sound system. The receiver--or sound bar or home theater system or whatever--must also support ARC for this feature to work (more info).
