scope:

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 transmitter-signature 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.

The present 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.
