Full Description

The present document should be read in conjunction with the normative document [i.2] in order to assist networkoperators, systems integrators, and equipment manufacturers in the realization of satellite based interactive services.The present document should be interpreted as recommendations or good practices but not as mandatory requirements.It is anticipated however that future procurement documents may reference elements of the present document as part oftheir system specification.

The present document is applicable to satellite systems as defined in [i.2]. In such a system the RCSTs receive aForward Link signal based on the DVB-S [i.1] or DVB-S2 [i.38] specifications. In a non-regenerative system, theReturn Link signal transmitted from the RCST is received by one or more Gateways, which also interact with the NCC.In regenerative systems as well as in transparent mesh systems, it can be possible to also have direct RCST-to-RCSTcommunications.

The system as defined in [i.2] may be used in all frequency bands allocated to FSS or BSS services, and the firstexpected implementations are in the bands listed in annex E.

Information concerning the most relevant international regulations and recommendations (ITU, ETSI, DVB, etc.) whichcould be applicable to the DVB-RCS terminals is included in clause 2.

The present document, as well as the normative document [i.2], cover two RCST profiles:Type A, which is able to support IP services only. This type of terminal supports two types of dataencapsulation, based on ATM or MPEG2.Type B, which is able to operate as RCST Type A and also to support native ATM protocols by encapsulatingATM cells within an MPEG2 Transport Stream on the forward link.The present document should not be used to justify the fulfilment of the essential requirements under article 3.2 of theR
