DVB-S is an abbreviation for "Digital Video Broadcasting — Satellite"; it is the original Digital Video Broadcasting Forward error correction and demodulation standard for Satellite Television and dates from 1995, in its first release, while development lasted from 1993 to 1997. The first application was commercially available in Australia via Galaxy, enabling digitally broadcast, satellite-delivered Television to the public.

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 & Ireland) via Astra in Europe, Dish Network and Globecast in the U.S. and Bell 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.
