Digicipher 2
Star Choice and 4dtv use Digicipher 2 encoder/decoders. PBS is moving away from this standard. It's gone to DVB MPEG 2 for their HD feed. HD NET and National Geographic are also using the DVB MPEG 2 as well. The Digicipher 2 will be around for a while longer because of so many companies are using it. But it is a standard that has had it's day and will be phased out over time. One of the 2 Showtime HD feeds dropped it a while back and replaced it w/ the Power Vue HD. TNT and Braves HD have gone Power Vu HD. These seem to be the up and coming standards on the BUD side of satellite.
I don't know what you are comparing SC to on C Band, but considering some of the bitrates I see coming off SC - you've fallen for something hook, line and sinker. D* overall has better bitrates than SC - not to mention there very old Motorola Encoders.
