DVB standards are affected by two major developments over the last years: the convergence to IP networks, and the increasing proliferation of mobile devices. This has led to the adoption of more efficient IP encapsulation protocols such as the Generic Stream Encapsulation (GSE) on one hand, and the specification of solutions targeted for mobile channels on the other hand. One such set of solutions...
On-Board Processing (OBP) technology has been already in the satellite scene for almost two decades. It has been a difficult path and for a long time considered an added but expensive value brought to the satellite payload. Today, it is a commercial and competitive reality. In the case of Thales Alenia Space (TAS), a new generation of OBP solutions are available to satisfy the always more demanding...
The current signalling framework for Digital Video Broadcasting (DVB) systems is based on MPEG-2 encoded Program Specific Information and System Information (PSI/SI) Tables that rely on the Transport Stream (TS). It is expected that in time, this architecture will be replaced by one based on the Generic Stream Encapsulation (GSE) protocol, paving the way for the convergence of DVB-S2 broadcast transmission...
The convergence between fixed and mobile network is the new paradigm in the world wide telecommunications network. Satellites are striving to become an important actor in the Next Generation Networks (NGN) by offering seamless integration with the terrestrial networks. Satellite systems can also provide the right complement in the convergence as one more access network that can cover vast regions...
This paper presents a revision of the status of current standards dedicated to mobile services systems, using combined satellite and terrestrial components transmission. The objective is the analysis of a hybrid system compatible with DVB-SH and SDR technologies, taking as a basis the work and studies performed in MOVISAT project.
This paper introduces the standardization work on C2P (Connection Control Protocol), carried on in the frame of ETSI SES BSM working group. As a first step, this work has defined a C2P solution for dynamic connectivity and QoS control in all types of DVB-RCS satellite networks.
Current DVB-RCS systems present an IPv4-interface and no commercial RCS systems have yet offered IPv6 support. This paper explores encapsulation issues for next generation DVB-RCS terminals that will support IPv6. It assess two alternatives: the Unidirectional Lightweight Encapsulation (ULE) and the Generic Stream Encapsulation (GSE). These are shown to improve efficiency and performance and have...
The evolution of existing satellite systems towards NGN infrastructure is a key element in the integration of satellite into new "convergence" concept. This requires a big effort taking into account the specific features and constraints of satellite networks compared to terrestrial networks. SLA management is one of the essential aspects to be studied. This paper will present an analysis...
Satellite systems are playing a key role like access network in the provision of next generation services. New concepts in the payloads architectures are required in order to support efficiently the new multimedia services. This paper will present the study of next generation payload architecture (in the context of Satsix project), taking into account the impact over different system scenarios.
