Draft Scope:

The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed 
for delivery of high-quality digital audio and video programmes and data services for mobile, portable and fixed 
reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands as well as for distribution 
through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terrestrial 
transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB 
system meets the required sharing criteria with other radiocommunication services. 
The present document defines the DAB transmission signal. It includes the coding algorithms for multiplexing of audio 
and video programmes and data services, channel coding and modulation. Provision is also made for transmission of 
additional data services which may be programme related or not, within the limit of the total system capacity. The 
present document provides information on the system configuration which includes information about the ensembles, 
services, service components and linking of them. 
The present document describes the nominal characteristics of the emitted DAB signal. The aspects related to the 
receiver design are outside the scope of the present document.
