DIGITAL CABLE SERVICES DEFINITION (continued): … A cable head-end (or headend) is the facility at a local cable TV office that originates andcommunicates cable TV services and cable modem services to subscribers.In distributing cable television services, the head-end includes a satellitedish antenna for receiving incoming programming. This programmingis then passed on to the subscriber. (Cable TV companies may also play videotapes and originate live programming.) Normally, all signals are those that are sent downstream to the subscriber, butsome are received upstream such as when a customer requests a pay-per-view program.When a cable company provides Internet access to subscribers, the head-endincludes the computer system and databases needed to provide Internet access.The most important component located at the head-end is the cable modemtermination system (CMTS), which sends and receives digital cable modem signalson a cable network and is necessary for providing Internet services to cablesubscribers.
