The Thor H-HDMI-RF-Petit-IR is a compact HDMI-compliant modulator with loop-out and IR so you can change the source Set Top Box from a different one via a Television. However, you can still use this modulator with any HDMI source like Blu-Ray, Apple TV, ROKU, PC, etc.
You can connect any amount of TV's you want to the RF output and view your programs over your existing coax network in up to 1080p resolution. You can also inject an RF input into the modulator, like an Antenna, and then add your HDMI-sourced product to inject into the ATSC channel lineup on a vacant frequency. This added accessibility along with the IR and digital link passing through your coax network will make adding programs, and adjusting the channel on your STB an easy-to-use solution.
Furthermore, the modulator also has an HDMI loop-out so if you have your unit stationed near a TV, and use the IR to control a second TV, the first TV can be fed with the HDMI input for monitoring or viewing. There is an LCD display with easy-to-use buttons, and of course, there is an RJ45 input so you can add your modulator to the LAN and control it through a WEB GUI. This unit also has all the major RF modulation standards built in, QAM(J83A/B), ATSC, ISDBT, and DVBT.
