TUTORIAL 3 DVB-S Standard in a nut shell Developed by the European Telecommunication Standard Organization (part of ITU), the DVB-S is a standard for satellite video broadcasting. This description is a summary of the standard as described in ETS Document ETS 300 421. The standard applies only to Ku-band satellites at 11/12 GHz. It is designed to provide Quasi Error Free (QEF) service at BER rates of between 10 -10 to 10 -11 . By using a fairly robust error protection scheme which can be varied depending on the channel environment, it can provide this QEF rate to channels with non- corrected error rates of 10 -1 to 10 -2 .
