SUMMARYThe current signalling framework for Digital Video Broadcasting systems is based on MPEG-2 encoded Program Specific Information and System Information tables that rely on the transport stream. It is expected that in the near future, this architecture will be replaced by one based on the Generic Stream Encapsulation protocol, paving the way for the convergence of DVB-S2 broadcast transmission networks and IP infrastructure. This paper presents a new lightweight Generic Stream Signalling Transport Protocol, which can be used to realise a transmission system based only on the Generic Stream Encapsulation and that efficiently supports filtering of Program Specific Information and System Information tables.
This paper intends to demonstrate the high versatility of Amerhis satellite system for all kind of environments where high-quality multimedia capabilities are needed, specially for remote areas or those with very low telecom infrastructures. The operation and exploitation possibilities of Amerhis system will be presented.
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 networks and IP infrastructure. A new lightweight Generic Stream Signalling Transport Protocol (GSSTP) is presented in this paper, which efficiently facilitates the filtering of PSI/SI Tables in a GSE-only transmission system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
