The 1T-CT-653 transmitter and 1T-CT-654 receiver employ HDMI v1.4 capability and HDBaseT 5Play™ technology to allow transmission of uncompressed 1080p high definition television signals over a single Cat.5e or Cat.6 cable. The system supports HDMI v1.4 signals, including 3D and 4K x 2K formats, and supports DVI signal transmission with appropriate DVI to HDMI Cable adapters. In addition, embedded 7.1CH LPCM, Dolby TrueHD and DTS-HD Master Audio capability is standard. The 1T-CT-653/1T-CT-654 system can achieve signal distribution distances of up to 100 meters (325 feet) for uncompressed 1080p signals without signal degradation. Control of the system can be accomplished via Ethernet, Infrared or RS-232 and POH (Power Over HDBaseT) technology is employed to allow powering of the Receiver from the Transmitter, negating the need for a separate power supply.
