HDMI to DVB-C (QAM) Modulator: Terra MHD003P, HDCP



The MHD003P R86105 modulator is a multifunctional device that encodes and modulates input HDMI signals with a Full HD resolution (1920x1080-30p) into the DVB-C QAM channel. The modulator has an HDMI input, an RF input, a 12 VDC input (a DC jack inside an F-like socket - the device cannot be powered via a coaxial cable).
MHD003P R86105 is a single-channel modulator, which means it cooperates with one signal source and generates a single DVB-C multiplex with one channel. With the RF channel selection and RF loop, the multiplex can be easily combined with existing channels in the antenna system.
Thanks to the support for HDCP protocol, the source signal may come from a variety of devices: a multimedia player, DVR or Blu-ray player, PC, STB etc. The modulator can distribute high-quality content in the form of a DVB-C multiplex via typical RF coaxial cables used in antenna and CCTV systems.
This feature makes it a good alternative to the distribution of HDMI signals with the use of HDMI splitters and cables.
