This study aims at gaining a good understanding of the likely evolution of satellite broadcasting during the period 2001-2007 in order to adequately plan the required developments for the future generation of broadcasting satellites. The end result shall be an identification of key technologies that have to be developed and a recommendation for a strategy for maximising the European industry/operators assets in the sector of satellite broadcasting. To this end, aspects of a technical nature (general system architecture, on board and on ground technology, services requirements), as well as of a regulatory, marketing, commercial and business nature, will have to be analysed. The work undertaken under this project encompasses all these aspects. This study is limited to geostationary broadcasting satellite systems, but includes aspects related to nomadic and mobile users.
generation of BSS will face more demanding service requirements at least for what concerns bandwidth on demand, interactivity, security, privacy and intellectual property rights. 4 main issues are shaping the evolution of satellite broadcasting:
Moreover 3 different types of constraints must be taken into account:
The study was broken down into 5 tasks and organised in three phases :
The next generation of BSS should respond in an efficient way to the changing broadcasting markets demands and the requirements of the multimedia services. The study has identified those BSS system architectures that are most promising in that respect, based on market and value chain analyses which have led to the following conclusions:
Therefore to remain competitive versus cable and digital terrestrial TV, NGBSS shall support native interactive services (PPV ordering, t-commerce, billing, games, Internet) in order to be able to offer a package of bundled services. In that context, the following BSS system architectures, which can provide two-way interactive services, were studied:
Multi Ka beams on forward and return links with
This scenario is the best adapted to two way access & peer to peer but requires significant satellite payload development. It has the lowest cost per interactive user.
Multiple Ku band regional beams on the, forward link with
This scenario is the best fit for future DTH-TV (regional broadcasting & micro-broadcasting), but requires significant satellite payload & platform development.
Overall, Scenarios 2 & 3 are preferred from future services point of view
Current Status (dated 23 May 2002)
The study is completed Early Spring 2002. Main findings are the following:
The continuous and rapid evolution of the broadcasting market requires to continuously update the appraisal of its environment (commercial and technical) to derive an adequate strategy.
