Understanding HD to Coax Modulators
An HD to coax modulator is a device that converts an HD signal into a format compatible with coaxial cables, allowing for easy and efficient distribution over existing coaxial cable infrastructure. This conversion process enables users to transmit HD signals over long distances without compromising on quality.
How Does an HD to Coax Modulator Work?
HD to coax modulators utilize advanced encoding and modulation techniques to convert digital HD signals into RF signals compatible with coaxial cables. The device takes the HDMI or SDI input and converts it into a standard MPEG transport stream. This transport stream is then modulated onto a specific RF channel using modulation standards such as QAM (Quadrature Amplitude Modulation)or COFDM (Coded Orthogonal Frequency Division Multiplexing). The modulated signal is then combined with the existing coaxial cable infrastructure and distributed to the desired destination.
