Samsung TVs support ARC (Audio Return Channel) function via HDMI cable. ARC enables the output of digital sound using just an HDMI cable. However, ARC is only available through an HDMI (ARC) port and only when the TV is connected to an ARC-enabled AV receiver.

i'm not sure this meaning arc can only be use with ARC-enabled AV receiver!!
