VIERA Link lets you operate SC-XH50 with a single VIERA TV remote control. With VIERA Link, there's no more need to switch between multiple remote controls. Further, ARC (Audio Return Channel) feature makes it possible to receive audio signals from the TV, on top of the preexisting HDMI function of sending audio/video signals to the TV with just one cable. This simplifies connection by eliminating the audio cable connection between the TV audio output and the main unit's audio input.
* ARC compatible TV is required.
