D2-MAC

D2-MAC is a satellite television transmission standard, a member of Multiplexed Analogue Components family. It was created to solve D-MAC's bandwidth usage by further reducing it, allowing usage of the system on cable and satellite broadcast. It could carry four high quality (15 kHz bandwidth) sound channels or eight lower quality audio channels. It was adopted by Scandinavian, German and French satellite broadcasts (CNBC Europe, TV3 (Sweden), TV3 (Denmark), EuroSport, NRK 1, TV-Sat 2, TDF 1, TDF 2, etc). The system was used until July 2006 in Scandinavia and until the mid-1990s for German and French sound channels.
