Description
Summary:DVB-S was initially targeting unidirectional services such as broadband TV broadcasting. DVB-S2, the newest evolution of the standard is rather packet delivery oriented. Together with an RCS return channel, it constitutes an improved network to convey IP based traffic. This paper addresses the issues relating to transporting voice over IP via a DVB-S2 link. Tests were performed on a real DVB-S2/RCS test bench part of the DVB-S2 experiment infrastructure. The standard flexibility, in comparison to DVB-S, to encapsulate different lengths of IP packets allowed acceptable performances. Through an efficient sizing of IP packets within a mixed traffic (voice and data) it is possible to improve encapsulation efficiency. In addition, a focus on the voice behaviour during fading event in an adaptive coding and modulation mode, showed acceptable quality.
