The signal can support extra audio out by optical cable. Without adding an additional HDMI Cable this switch will reverse the audio to the AV amplifier through the HDMI cable connection allowing your HDTV to receive audio and video content. Switch between four HDMI sources using the buttons on the switch or the included IR remote. This HDMI switch is compatible with all HDMI sources and supports HDCP.
The HDMI organization has recently upgraded HDMI to include several new and exiting functions. HDMI v1.3 cables are already being phased out by the superior HDMI v1.4 cables. The problem is that most HDMI devices (including switches) do not support these new functions. This HDMI switch will allow you to enjoy all the new functions of HDMI v1.4.
HDMI Ethernet Channel: Allows you to use HDMI devices that are IP enabled such as HDTVs and Blu-Ray players with Ethernet enabled features. This would allow you to use your Netflix instant viewing app on your new Ethernet enabled HDTV, for instance.
Audio Return Channel: Allows you to connect an HDMI TV with a tuner to an audio receiver via HDMI. This allows you to send audio from your TV to the receiver "upstream" without giving up the "downstream" video from a video source connected to your receiver (like from a Blu-Ray player or gaming console).
3D Support: This cable has added 3D support, supporting every brand and type of active and non-active 3D protocols.
4K support: This future proofs your HDMI cable; supporting resolutions that far surpass 1080p (4096×2160 p24 to be exact, 1080p is 1920x1080).
Content Type Control: Your HDTV can now tell what is connected to it (for supported devices), allowing it to automatically adjust settings to best reproduce your video source's resolution, color setting, and more.
Additional Color Spaces/Spectrums: There are some colors that the RGB spectrum does not include, and many of these color spectrums are being incorporated in digital still photography and other applications, such as sYCC601, Adobe RGB, and Adobe YCC601 color spaces.
