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 2 of a multi-part deliverable covering the optional extensions of the DVB-S2 system, denoted "DVB-S2X", as identified below: Part 1: "DVB-S2"; Part 2: "DVB-S2 Extensions (DVB-S2X)".

ETSI ETSI EN 302 307-2 V1.1.1 (2015-02)7 Modal verbs terminology In the present document "shall", "shall not", "should", "should not", "may", "may not", "need", "need not", "will", "will not", "can" and "cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). "must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The optional extensions of the S2 system have been approved in 2014 and are identified by the S2X denomination. Such extensions are non-backwards-compatible with EN 302 307 (V1.1.1) [4], are optional for the implementation of new receivers under EN 302 307-1 [3], but are normative for the implementation of receivers under the present document: mapping of specific S2X building blocks to application areas is specified in Table 1. For every S2X application area, as defined in Table 1, the configurations for the corresponding S2 application area, as defined in EN 302 307-1 [3], Table 1, will be implemented. In case of conflicts the definition of the S2X application area applies. The present document targets the core application areas of S2 (Digital Video Broadcasting, forward link for interactive services using ACM, Digital Satellite News Gathering and professional digital links such as video point-to-point or Internet trunking links), and new application areas requiring very-low carrier-to-noise and carrier-to-interference operation (VL-SNR). In particular for DTH, a possible use case is the launch of UHDTV-1 (e.g. 4k) television services in Ku-/Ka-band that will adopt HEVC encoding. In this context it may be desirable to eventually use fragments of smaller blocks of capacity on two or three DTH transponders and bond them into one logical stream. This permits to maximize capacity exploitation by avoiding the presence of spare capacity in individual transponders and/or to take maximum advantage of statistical multiplexing. The S2X system offers the ability to operate with very-low carrier-to-noise and carrier-to-interference ratios (SNR down to -10 dB), to serve markets such as airborne (business jets), maritime, civil aviation internet access, VSAT terminals at higher frequency ranges or in tropical zones, small portable terminals for journalists and other professionals. Furthermore, the S2X system provides transmission modes offering significantly higher capacity and efficiency to serve professional links characterized by very-high carrier-to-noise and carrier-to-interference ratios conditions. The present document reuses the S2 system architecture, while adding finer MODCOD steps, sharper roll-off filtering, technical means for bonding of multiple transponders and additional signalling capacity by means of an optional periodic super-frame structure, extended PLHEADER signalling schemes and the support of GSE-Lite signals.
The present document maintains the same clause numbering as EN 302 307-1 [3], in order to facilitate cross-reference. SIST EN 302 307-2 V1.1.

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.

Introduction
The optional extensions of the S2 system have been approved in 2014 and are identified by the S2X denomination.
Such extensions are non-backwards-compatible with EN 302 307 (V1.1.1) [4], are optional for the implementation of
new receivers under EN 302 307-1 [3], but are normative for the implementation of receivers under the present
document: mapping of specific S2X building blocks to application areas is specified in Table 1. For every S2X
application area, as defined in Table 1, the configurations for the corresponding S2 application area, as defined in
EN 302 307-1 [3], Table 1, will be implemented. In case of conflicts the definition of the S2X application area applies.
The present document targets the core application areas of S2 (Digital Video Broadcasting, forward link for interactive
services using ACM, Digital Satellite News Gathering and professional digital links such as video point-to-point or
Internet trunking links), and new application areas requiring very-low carrier-to-noise and carrier-to-interference
operation (VL-SNR).
In particular for DTH, a possible use case is the launch of UHDTV-1 (e.g. 4k) television services in Ku-/Ka-band that
will adopt HEVC encoding. In this context it may be desirable to eventually use fragments of smaller blocks of capacity
on two or three DTH transponders and bond them into one logical stream. This permits to maximize capacity
exploitation by avoiding the presence of spare capacity in individual transponders and/or to take maximum advantage of
statistical multiplexing.
The S2X system offers the ability to operate with very-low carrier-to-noise and carrier-to-interference ratios (SNR
down to -10 dB), to serve markets such as airborne (business jets), maritime, civil aviation internet access, VSAT
terminals at higher frequency ranges or in tropical zones, small portable terminals for journalists and other
professionals. Furthermore, the S2X system provides transmission modes offering significantly higher capacity and
efficiency to serve professional links characterized by very-high carrier-to-noise and carrier-to-interference ratios
conditions.
The present document reuses the S2 system architecture, while adding finer MODCOD steps, sharper roll-off filtering,
technical means for bonding of multiple transponders and additional signalling capacity by means of an optional
periodic super-frame structure, extended PLHEADER signalling schemes and the support of GSE-Lite signals.
The present document maintains the same clause numbering as EN 302 307-1 [3], in order to facilitate cross-reference.

Introduction
The optional extensions of the S2 system have been approved in 2014 and are identified by the S2X denomination.
Such extensions are non-backwards-compatible with EN 302 307 (V1.1.1) [4], are optional for the implementation of
new receivers under EN 302 307-1 [3], but are normative for the implementation of receivers under the present
document: mapping of specific S2X building blocks to application areas is specified in Table 1. For every S2X
application area, as defined in Table 1, the configurations for the corresponding S2 application area, as defined in
EN 302 307-1 [3], Table 1, will be implemented. In case of conflicts the definition of the S2X application area applies.
The present document targets the core application areas of S2 (Digital Video Broadcasting, forward link for interactive
services using ACM, Digital Satellite News Gathering and professional digital links such as video point-to-point or
Internet trunking links), and new application areas requiring very-low carrier-to-noise and carrier-to-interference

In particular for DTH, a possible use case is the launch of UHDTV-1 (e.g. 4k) television services in Ku-/Ka-band that
