DHEI Components and Configuration

DHEI commonly includes several components that work together to extend the capability of a cable headend. the primary components of DHEI consist of −

• Input/output modules − These modules obtain signals from the satellite tv for pc or terrestrial resources and convert them into digital signals that can be processed through the DHEI

• Processing modules − These modules perform various signal processing features, which include modulation, demodulation, multiplexing, and scrambling. In addition they include errors correction and detection competencies to ensure signal high-quality.

• Manage modules − These modules allow remote control and monitoring of the DHEI device. They also permit operators to configure and manage the system parameters, consisting of channel allocation and modulation settings.

• Power supply unit − This unit offers the important power to perform the DHEI device.

The configuration of DHEI depends on the particular needs and requirements of the cable operator. However, in general, DHEI is established in the cable headend and linked to the satellite tv for pc or terrestrial resources through input/output modules.

The processed signals are then allotted to subscribers via the cable network. The DHEI device may be configured and controlled remotely using control modules.
