The DVB project is an Alliance of about 250-300 companies, originally of European origin but now worldwide. Its objective is to agree specifications for digital media delivery systems, including broadcasting. This paper is aimed at stimulating some thoughts on how DVB derived standards and services will evolve in the future, with a bias towards satellite delivered services
Economic communities based in scattered or remote rural areas, such as agriculture and maritime, share a pronounced need for both broadband connectivity at remote geographical locations and interactive multimedia content delivering education system. Accordingly, each of these sectors also has their own special requirements with regard to the type of content needed to be delivered. Our papers reports...
This paper presents some enhanced techniques that can be successfully applied to the return link of interactive satellite terminals with some estimated performance gains. In particular the following techniques are presented: i) an enhanced forward error correction (FEC) scheme with improved performance with respect to the current turbo code, ii) a novel framing and layer 2 encapsulation scheme optimized...
In this paper a new hybrid network solution relying on synergy between a IEEE 802.16-based networks (commonly known as a WiMAX networks) and digital video broadcasting-return channel satellite (DVB-RCS) networks is presented. The novelty of the architecture proposed is that of employing DVB-RCS domains as a backhaul for content delivery to IEEE 802.16 domains. It goes on to analyse key implementation...
Advantech believes that the combined use of DVB-S2 and DVB-RCS technologies, plus complementary technologies such as Ka band satellites, can produce a very low cost broadband delivery platform for both broadcast and interactive services. A return channel is rapidly becoming mandatory to serve both the needs of the content provider and to enable delivery optimisations (such as adaptive coding and modulation)...
This paper focusses on the network-layer interface to the physical layer of the second generation standard for DVB over satellite, DVB-S2. It considers the transport of IP data using both an MPEG-2 transport stream, and the continuous generic stream. It highlights design issues, leading to a new proposed encapsulation method that improves efficiency by reducing protocol overhead while providing strong...
Both constant and variable forward error correcting (FEC) coding is provided by the DVB-S2 system. Variable FEC can be used to provide different levels of error protection according to applications, & may be combined with the use of return channels, to achieve adaptive coding. The novel idea explained in this paper, introduces an algebraic method for construction of well-structured low density...
The use of DVB-S and DVB-RCS for conducting two-way communications from small satellite terminals has become well established in Europe and elsewhere. During the development of the DVB-RCS standard in DVB and ETSI the possibility of limited use for satellite terminals that were moving was considered in Jan 2004 and, after much discussion, incorporated into Annex L of the Guideline document associated...
