Central control required within some systems to provide entralized functions as remodulation, re-timing, message accountability, contention control, diagnostic control, and access.
A central control device required by some networks (e.g., LANs or MANs) to provide such centralized functions as remodulation, retiming, message accountability, contention control, diagnostic control, and access to a gateway. A central control device, within CATV systems, that provides centralized functions such as remodulation.
the site in a cable system or broadband coaxial network where the programming originates and the distribution network starts. Signals are usually received off the air from satellites, microwave relays, or fiber-optic cables at the head end for distribution.
A point from which a local cable television network operates in a community. Has satellite uplinks to gather television feeds.
Where cable-TV signal processing occurs; where the array of satellite dishes that cable TV companies use, picks up their programming transmissions before being sent down its coax cables for distribution.
The cable company's main signal reception and distribution facility. The head end is the cable TV equivalent of a phone company CO, and all TV cables for a given area route back to a single head end.
The equipment located at the start of a CATV system. The location where signals are processed and combined prior to distribution.
Electronic control center generally located at the antenna site of a CATV system. Usually includes antennas, preamplifiers, frequency converters, demodulators, and other related equipment to amplify, filter, and convert incoming broadcast TV signals to cable system channels.
The originating point in a one-to-many network system (such as a TV cable network), or a central information-gathering point of an Internet service provider.
A central point in a broadband network that receives signals on one set of frequency bands and retransmits them on another set of frequencies. The head end is viewed as a central hub. Every transmission on a broadband network must go through the head end.
The originating point of a signal in cable TV systems. At the head end, you'll often find a large receiving satellite antennae.
The central facility where signals are combined and distributed in a cable television system.
The electronic equipment located at the start of a cable television system, usually including antennas, earth stations, preamplifiers, frequency converters, demodulators, modulators and related equipment.
This is where a cable system receives programming from various sources. It then combines these sources onto its cable, assigns channel numbers and sends it off to the customers. Essentially it is where the transmissions begin on a cable network.
The main or top transmitting device in a broadband network where all transmission are distributed.
