Appendix F. DVB-S/S2 BER

Performance at Quasi-Error Free

(QEF)

The Forward Error Correction (FEC) technique used in Digicast receivers complies with ETSI
EN 300 421 for DVB-S and ETSI EN 302 307 for DVB-S2. The information provided below
demonstrates the Es/No to provide "Quasi Error Free" (QEF) performance for a packet error rate
