The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http://ipr.etsi.org). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members' activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. The present document is part 1 of a multi-part deliverable covering the DVB Interactive Satellite System specification, as identified below: TS 101 545-1: "Overview and System Level specification"; EN 301 545-2: "Lower Layers for Satellite standard"; TS 101 545-3: "Higher Layers Satellite Specification"; TR 101 545-4: "Guidelines for Implementation and Use of EN 301 545-2"; TR 101 545-5: "Guidelines for the Implementation and Use of TS 101 545-3".

5 ETSI TS 101 545-1 V1.2.1 (2014-04) Introduction EN 301 790 [1] defines the first generation of DVB-RCS which is a system providing an interaction channel for satellite distribution systems. Together with its guidelines (TR 101 790 [i.1]) the present document describes how such system can be built on the physical and MAC layers to provide an efficient way of turning a satellite broadcast TV into a full VSAT solution capable of transporting IP traffic in a satellite-only system. Since the original definition of DVB-RCS systems, several versions of the standard were issued, describing the requirements for the implementation of a system providing an interaction channel for satellite distribution systems. The sum of these specifications allowed to adapt the DVB-RCS systems to different market segments from small to large networks and from fixed to mobile terminals but it appears that the evolutions of the physical layer techniques and the stabilisation of IP standards now deserves deeper changes which can only be implemented in a consistent way via the definition of a second generation system. The requirements in the present document have been introduced in order to provide the best possible interoperability between terminals and hubs, thus defining not only the lower layers of the system (up to layer 2) but also network functions as well as management and control capabilities. As these requirements combined together may end up in a very complex terminal design, the present document also describes subsets of capabilities known as profiles that can be used together to address a given market segment. ETSI

6 ETSI TS 101 545-1 V1.2.1 (2014-04) Scope 1 The present document establishes the system specifications for the 2nd Generation Interactive DVB Satellite System (DVB-RCS2) and represents the first part of the multi-part specification of that system. It also gives links to the adequate sections into the detailed specification documents and explains how the features should be combined together to make a terminal compliant with different subsets of specifications mentioned here as profiles. General terms and definitions are given in the present document which can be found also in the other parts of the DVB-RCS2 multi-part specification. References 2 References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.

Layer 1 Regenerative and Re-multiplexing System: satellite interactive network that relies on an on-board regenerative processor to demodulate upcoming MF-TDMA data from terminals and generate a TDM downlink signal with this data NOTE: Such system looks like an RCS second generation system from the layer 1 RCSTs perspective. management plane: communications that carry information to maintain the network and to perform operational functions user plane: communications that carry user information 3.2 Symbols For the purposes of the present document, the following symbols apply: α Eb/N0 Es/N0 f0 fN NR,max Nrand Nslots Rs Roll-off factor Ratio between the energy per information bit and single sided noise power spectral density Ratio between the energy per transmitted symbol and single sided noise power spectral density Carrier frequency Nyquist frequency Number of replicas in a frame 12-bit random number used as a random seed value during CRDSA frame decoding Number of the slots in the frame Symbol rate corresponding to the bilateral Nyquist bandwidth of the modulated signal 3.3 Abbreviations For the purposes of the present document, the following abbreviations apply: ACM BPSK CCM CLI CPM CRC CRC32 CRDSA CSC DA DAMA DCP DHCP DL DoS DSA DTP Adaptive Coding and Modulation Binary Phase Shift Keying Constant Coding and Modulation Command Line Interface Continuous Phase Modulation (or Modulator) Cyclic Redundancy Check Cyclic Redundancy Check (32 bits) Contention Resolution DSA Common Signalling Channel Dedicated Access Demand Assignment Multiple Access Dynamic Connectivity Protocol Dynamic Host Control Protocol DownLink Denial-of-Services Diversity Slotted Aloha Digital Transparent Processor ETSI
