The HDMOD-3B is a high quality DVB-T "Home" modulator with HDMI loop-through circuit. It receives one HDMI signal as input and converts it into one RF DVB-T channel output as well as in HDMI out. The excellent picture (Full HD 1920*1080-30p) and modulation quality (MER~35dB) renders the HDMOD-3B an ideal solution for distributing SD/HD digital signals received from any device with an HDMI output (e.g. a DVD player, STB or camera in a CATV network using the DVB-T technology).

The user has the ability to control the device remotely using a Bluetooth interface by downloading and using the appropriate application from the Android Play store or iOS App store for free. Finally, the HDMOD-3B's small size and metal case provides excellent electromagnetic shielding as well as great temperature dissipation and rigidness.
