ODG (Origin Data Global)
HDMI Modulator: Definition & Features Understanding HDMI ModulatorsWhat are HDMI Modulators?. An HDMI modulator is a device that receives a high definition multimedia interface (HDMI) signal and modulates it into a radio frequency (RF) signal. The modulation is important because of how RF signals can be distributed over coaxial cables, enabling the distribution of HD content to various locations using coaxial cables. An HDMI modulator can be thought of as a translator, as it takes the language of HDMI and speaks in coaxial cable...
