At the local headend, the feed signals from the individual television channels are received by dish antennas from communication satellites.
Additional local channels, such as local broadcast television stations, educational channels from local colleges, and community access channels devoted to local governments ( PEG channels ) are usually included on the cable.
Commercial advertisements for local business are also inserted in the programming at the headend ( the individual channels, which are distributed nationally, also have their own nationally oriented commercials ).
