This Recommendation is intended for use in the assessment of systems which introduce impairments sosmall as to be undetectable without rigorous control of the experimental conditions and appropriate statisticalanalysis. If used for systems that introduce relatively large and easily detectable impairments, it leads toexcessive expenditure of time and effort and may also lead to less reliable results than a simpler test. ThisRecommendation forms the base reference for the other Recommendations, which may contain additionalspecial conditions or relaxations of the requirements included in this Recommendation.

DVB-S (EN 300 421 [2]) a été introduit sous la forme d'une norme en 1994 et le DVB-DSNG (EN 301 210 [3]) en 1997. La norme DVB-S spécifie la modulation QPSK et le codage concaténé des canaux de Reed-Solomon et de convolution et est à présent utilisée par la plupart des opérateurs satellites dans le monde entier pour les services de télévision et de diffusion de données. Le DVB-DSNG spécifie, en plus du format DVB-S, l'utilisation de la modulation 8PSK et MAQ 16 pour les nouveaux services de reportage d'actualités et de contribution par satellites.
