A headend is a facility in a cable television system where signals are received, processed, and distributed to subscribers. It serves as the central hub that collects content from various sources, such as satellite feeds, local broadcasts, and other media providers. The headend converts these signals into a format suitable for transmission over the cable network. In addition to processing video signals, the headend also manages data services and internet connectivity for subscribers. It plays a crucial role in ensuring that viewers receive high-quality programming and reliable service. The technology used in a headend can include servers, routers, and other equipment necessary for signal management.
