The HDMI to Two SDI Converter allows HDMI signals to be shown on two SDI monitors while ensuring high bit rates of 2.970 Gbit/s to give you high resolution signal without any loss. For professionals, it is now easier to convert your HD HDMI signal with audio to SDI for long distance transmission and display your work on SDI display.  

Features:
Allows HDMI signal sources to be shown on two SDI monitors and SDI interface operates at bitrates of 2.970 Gbit/s, 1.485 Gbit/s, and 270 Mb/s. 
Supports HDMI input timings of 720p@50/60, 1080i@50/60, 1080p@50/60.
Allows to convert HDMI signal to SDI, including converting 480i/576i to SD-SDI (SMPTE 259M-C, at bitrates of 270 Mbit/s), 720p/1080i to HD-SDI (SMPTE 292M, at bitrates of 1.485 Gbit/s or 1.485/1.001 Gbit/s), 1080p to 3G-SDI (SMPTE 424M/425M-AB, at bitrates of 2.970 Gbit/s and 2.970/1.001 Gbit/s).
Supports SDI output distance up to 100 meters (3G-SDI), 200 meters (HD-SDI), or 300 meters (SD-SDI).
Superior performance and easy to operate.

Note:
SDI: The SDI refers to an acronym for the serial digital interface that sequentially transmits individual bits of a data word and corresponding data through a single channel, which shall be processed before transmission due to its high data rate.
HDMI: High Definition Multimedia Interface, an all-digital video and audio transmission interface that can transmit uncompressed audio and video signals, can be used in set-top boxes, DVD players, personal computers, video games, integrated amplifiers, digital audio and televisions and can simultaneously transmit audio and video signals, greatly simplifying system installation due to the same cable for audio and video signals.
