Kramer’s TP-580T and TP-580R are a transmitter and receiver, respectively, using HDBaseT Lite technology to send HDMI with embedded audio, bi-directional RS232 and IR over distances of up to 230 feet (70 meters). For resolutions above 1080p60 and up to 4K, they can transmit up to 131 feet (40 meters), according to Kramer.
The TP-580T and TP-580R support HDCP, 3D Pass-through, Deep Color, x.v.Color, CEC, Lip Sync, HDMI Uncompressed Audio Channels, Dolby TrueHD and DTS-HD. They are each housed in a compact Kramer Tool enclosure and powered by the supplied 12v adapter.
So far, Epson and Panasonic (and soon Mitsubishi and InFocus) have direct HDBaseT inputs. You can get all the specs here.
