1 – 8 HDMI Digital RF Modulator CC (Closed Captioning)
The signal source could be from any STB, satellite receiver, closed-circuit television cameras and antenna etc. Its output signal is designed to work with any TV or STB. Because it comes standard with every RF modulation standard builtin, this device can work anywhere in the world in a plug and play format.
This unit is similar to our popular line H-1,2,4 HDMI-QAM-IPLL product line, but it has some differences .It is less expensive unit, each program is modulated on its own frequency , CATV RF ouput only, no IPTV output
