This product is compliant with the latest HDCP 2.2 protocol as well as HDCP 1.4. Audio Support The GTB-UHD-HBT supports Stereo and Multichannel digital audio including 7.1 channels of LPCM as well as High Bit Rate (HBR) digital audio formats such as Dolby® TrueHD and DTS-HD Master Audio. TOSLINK® Optical Digital Audio can be sent from the display side back to the source and analog audio can be extended from the source side to the Receiver. IP & Serial Extension This product provides RS-232 and 2-way IR extension between the Sender and the Receiver units, facilitating the control of A/V sources placed near the Sender unit and sending automation commands to the display or another device placed near the Receiver unit. Bi-Directional Power Over HDBaseT Gefen Bi-Directional POL (Power Over Line) technology powers the Sender or the Receiver unit using the same cable that extends the HDMI signal. Only one of the two units will need a power supply. This feature simplifies installation in cases when an electrical outlet may not be available near the source or the display.
