Gefen's 6x2 HDMI Switcher is a small metallic unit equipped with six HDMI inputs and two HDMI outputs. Six inputs accommodate the simultaneous connection of up to six high definition video sources, such as satellite systems and HD DVD players. Two outputs send the high definition audio/video signals to two high definition displays or one display and one audio receiver. Digital audio and high definition video for each source is accessed immediately when the unit inchswitchesinch to it. You control the switching by using the IR remote that comes with the unit. HDCP (high bandwidth digital content protection) is a standard encoded into the video signal to prevent it from being pirated. If a source device is HDCP coded and is connected to a display or projector without the proper decoding mechanism, the picture is relegated to inchsnowinch or in some cases, very low (480P) resolutions of the images. In order to see high resolution digital video with HDCP compliance, both the source, the display and anything in between must be equipped with HDMI connections that can enable HDCP decoding, such as the 6x2 HDMI Switcher. You simply connect all your sources to the Switcher's inputs. You have a choice of connecting either two displays or a display and a receiver to the Switcher's outputs. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the IR remote.
