Abstract :
In this paper we use a combination of adaptive coding and modulation with Diff-Serv techniques to optimize bandwidth allocation within DVB-S2 satellite links and propose logical grouping of receivers. Especially for scenarios setups where receivers of specific services can be grouped, additional information concerning ab area of influence of this service can be utilized to down- or upgrade modulation scheme and coding rate with minimal impact on QoS.
