“…This differentiation is performed in a static manner. In case that dynamic bandwidth management is required, a mechanism like the one described in [13] can be employed. Video streams are served by a real-time H.264 encoder fed by a live source, and a VoIP Gateway utilizing H.323/SIP acts as an interface to the public PSTN network.…”

This paper discusses the convergence of digital broadcasting and Internet technologies, by elaborating on the design, implementation, and performance evaluation of a hybrid terrestrial/satellite networking infrastructure, enabling triple-play services access in rural areas. At local/district level, the paper proposes the exploitation of DVB-T platforms in regenerative configurations for creating terrestrial DVB/IP backhaul between the core backbone (in urban areas) and a number of intermediate communication nodes distributed within the DVB-T broadcasting footprint (in rural areas). In this way, triple play services that are available at the core backbone, are transferred via the regenerative DVB-T/IP backhaul to the entire district and can be accessed by rural users via the corresponding intermediate node. On the other hand, at regional/national level, the paper proposes the exploitation of a satellite interactive digital video broadcasting platform (DVB S2/RCS) as an overlay network that interconnects the regenerative DVB-T/IP platforms, as well as individual users, and services providers, to each other. Performance of the proposed hybrid terrestrial/satellite networking environment is validated through experimental tests that were conducted under real transmission/reception conditions (for the terrestrial segment) and via simulation experiments (for the satellite segment) at a prototype network infrastructure.

“…Based on these two policies, different resource optimization algorithm should be applied. Currently, we found that most optimization algorithms are based on the assumption that all data to be sent already exists in the DVB radio station server( [3], [5], [6]), which means they all follow policy 1, and no algorithm considering the characteristics of the coming Internet data streams is found yet. Hence, the current existing algorithms may not be fit for more real-time demanding services which prefer policy 2 in BNCC and they won't be able to fully exploit the BNCC resources.…”

Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current access technologies like UMTS, WLAN, and so forth. Combined with other media as a return channel for user requests and acknowledgement signaling, DVB-T can provide interactive data services. In this paper, the integrated Internet and DVB-T network is proposed to provide broadband Internet access services for users with high mobility. In order to make effective use of valuable DVB-T resources, we present a bandwidth allocation algorithm SOBAM(Satisfaction Oriented Bandwidth Allocation Method), which is based on a new concept: user satisfaction. The simulation results powerfully show that SOBAM gives good QoS differentiation and make plentiful utilization of DVB-T available bandwidth. With SOBAM, the integrated Internet and DVB-T network can provide a soft system capacity which is similar to the one in CDMA networks.Keyword: DVB-T, integrated network, satisfaction, resource management Abstract-Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current existing access technologies like UMTS, WLAN, and so forth.

“…A triple-play service scenario requires simultaneous handling and adaptation of both unicast and multicast, interactive and streaming services. A crosslayer approach, extending to the services layer, is required as the one proposed in [6], but at this time including physicallayer adaptation. This is achieved by the proposed satellite resource management system (SRMS), currently under development in the frame of the EU-funded IST IMOSAN (FP6-IST-027457) project.…”

This paper presents a mechanism for dynamic rate control of satellite integrated services, based on a cross-layer approach, utilising link quality feedback from the satellite terminals. The mechanism, namely, satellite resource management system (SRMS) relies on the adaptive coding and modulation (ACM) capabilities of DVB-S2 in order to perform real-time adjustments on the physical, network and services layer and optimise the usage of satellite spectrum. The functionality of the SRMS is discussed along with its implementation in the frame of the IST IMOSAN Project. Simulation results are presented, involving modelled rain fading and prioritised heterogeneous services, which illustrate the efficiency of the proposed solution against current static transmission schemes.
