Since around 1994, digital SNG uplinks have been made possible by the development of low bit-rate digital compression encoders. The development of digital compression encoders that could run at bit-rates as low as 8 Mbps created an opportunity for use for SNG, and this in turn led to the realization that more channels could be fitted on a satellite, which led to lower costs to use the satellite. So the advantage offered was lower power uplinks and narrower bandwidth channels on the satellite, offering the possibility of lower satellite charges. Instead of a 27 MHz channel for ...
