Extender for HDMI 3DTV extends HDMI including multi-channel digital audio at resolutions of up to 1080p Full HD and Ultra HD 4K x 2K (3840 x 2160 @ 30Hz) up to 330 feet (100 meters) using one CAT-5e cable for the extension. This product also provides an IR back channel to control AV sources using the same CAT-5 cable extension. Using this channel with the built-in IR "eye" on the receiver, or an optional RMT IR Extender, simply point IR remote(s) of the A/V device towards the display to control Hi-Def sources as if they were located in the same room or proximity to the display.
