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 standardization interoperability and future proof. specifications, The present document is part 1 of a multi part deliverable covering a second generation modulation and channel. coding system denoted DVB S2 as identified below,Part 1 DVB S2.

Introduction, DVB S EN 300 421 2 was introduced as a standard in 1994 and DVB DSNG EN 301 210 3 in 1997 The DVB S. standard specifies QPSK modulation and concatenated convolutional and Reed Solomon channel coding and is now. used by most satellite operators worldwide for television and data broadcasting services DVB DSNG specifies in. addition to DVB S format the use of 8PSK and 16QAM modulation for satellite news gathering and contribution. Since 1997 digital satellite transmission technology has evolved somewhat. New channel coding schemes combined with higher order modulation promise more powerful alternatives to. the DVB S DVB DSNG coding and modulation schemes The result is a capacity gain in the order of 30 at. a given transponder bandwidth and transmitted EIRP depending on the modulation type and code rate. Variable Coding and Modulation VCM may be applied to provide different levels of error protection to. different service components e g SDTV and HDTV audio multimedia. In the case of interactive and point to point applications the VCM functionality may be combined with the use. of return channels to achieve Adaptive Coding and Modulation ACM This technique provides more exact. channel protection and dynamic link adaptation to propagation conditions targeting each individual receiving. terminal ACM systems promise satellite capacity gains of up to 100 to 200 In addition service. availability may be extended compared to a constant protection system CCM such as DVB S or. DVB DSNG Such gains are achieved by informing the satellite up link station of the channel condition. e g C N I of each receiving terminal via the satellite or terrestrial return channels. DVB S and DVB DSNG are strictly focused on a unique data format the MPEG Transport Stream. ISO IEC 13818 1 1 or a reference to it Extended flexibility to cope with other input data formats such as. multiple Transport Streams or generic data formats is now possible without significant complexity increase. The present document defines a second generation modulation and channel coding system denoted the System or. DVB S2 for the purposes of the present document to make use of the improvements listed above DVB S2 is a. single very flexible standard covering a variety of applications by satellite as described below It is characterized by. a flexible input stream adapter suitable for operation with single and multiple input streams of various formats. packetized or continuous, a powerful FEC system based on LDPC Low Density Parity Check codes concatenated with BCH codes. allowing Quasi Error Free operation at about 0 7 dB to 1 dB from the Shannon limit depending on the. transmission mode AWGN channel modulation constrained Shannon limit. a wide range of code rates from 1 4 up to 9 10 4 constellations ranging in spectrum efficiency from. 2 bit s Hz to 5 bit s Hz optimized for operation over non linear transponders. a set of three spectrum shapes with roll off factors 0 35 0 25 and 0 20.
