Digital Video Broadcasting – Satellite (DVB-S) is the originalDVB standard forsatellite television and dates from 1995, in its first release, while development lasted from 1993 to 1997. The first commercial applications were byCanal+ in France[citation needed] andGalaxy in Australia, enabling digitally broadcast, satellite-deliveredtelevision to the public. According to ETSI,[1]
DVB-S was the first DVB standard for satellite, defining the framing structure, channel coding and modulation for 11/12 GHz satellite services.
It is used via satellites serving every continent of the world. DVB-S is used in bothmultiple channel per carrier (MCPC) andsingle channel per carrier modes forbroadcast network feeds as well as fordirect-broadcast satellite services likeSky UK and Ireland viaAstra in Europe,Dish Network andGlobecast in the U.S. andBell Satellite TV in Canada.
While the actual DVB-S standard only specifies physical link characteristics and framing, the overlaid transport stream delivered by DVB-S is mandated asMPEG-2, known asMPEG transport stream (MPEG-TS).
Someamateur television repeaters also use this mode in the1.2 GHz amateur band.
