Digital Video Broadcasting (DVB); Structure and
modulation of optional transmitter signatures (T2-
TX-SIG) for use with the DVB-T2 second
generation digital terrestrial television
broadcasting system

The present document describes an optional extension to the DVB-T2 second-generation transmission system for digital
terrestrial television broadcasting, as specified in [1]. This extension takes the form of the addition of transmittersignature
information, and is primarily intended for use in single-frequency networks (SFNs). The extension is made in
ways which are fully compatible with the original specification by exploiting some of its explicit provisions for future
expansion.
The primary purpose of the addition of transmitter-signature information described herein is to assist network operators
with the setting-up, maintenance, monitoring and fault-finding of their networks, by making it possible to identify the
individual contributions of different transmitters within a single-frequency network. However, once it is present the
transmitter-signature information could also be used for other purposes, e.g. applications requiring location information.
This document specifies the details of the additional signals, and must be read in conjunction with the DVB-T2
specification [1] for full understanding. In order to accommodate different purposes, and different scales of networks,
various options are provided; network operators can select from them to suit their requirements.
