Digital Video Broadcasting – Satellite (DVB-S) is the original DVB standard for satellite television and dates from 1995, in its first release, while development lasted from 1993 to 1997. The first commercial applications were by Canal+ in France and Galaxy in Australia, enabling digitally broadcast, satellite-delivered television to the public. According to ETSI, 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 both multiple channel per carrier (MCPC) and single channel per carrier modes for broadcast network feeds as well as for direct-broadcast satellite services like Sky UK and Ireland via Astra in Europe, Dish Network and Globecast in the U.S. and Bell 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 as MPEG-2, known as MPEG transport stream (MPEG-TS). Some amateur television repeaters also use this mode in the 1.2 GHz amateur band.
