INTRODUCTION

Television has evolved over the last halfcentury from an up-market entertainmentmediumto

becoming the major information tool around the world. Television is available to virtually all

people around the globe, be it individuallyor in a community setting.

The advent of the “personal computer”, enabling global reach and instant interaction has

escalated the demand for more and more information and the ability to respond toitinstantly.

It isthus that the broadcastersand content providersset out to seek new meansofdelivering

higher levels of content, be it in volume or quality using existing ornew transpor tmechanisms

available.

Digitalisation, taken from the world of information technology was the obvious choice. It

further brought the added benefitsof efficient use of spectrum and energy. Terrestrial

television hasto migrate from analogue to digital in order to survive in the new information

society.

Governments are keen to switch off the inefficient analogue broadcastsfor anumber of

obvious reasons, but only will be able to doso when consumersare confident that the new

proposition is attractive and affordable.

Due to the multitude ofcommunities, sometimes single operators, often on a country by

country basis dealing withthe parameters and standards options of launching Digital

Terrestrial services based on DVB, there is a natural tendency to create a variety of

incompatible platforms tied to particularTV operators, and this inturn does not allow for

economy ofscale for all parties concerned, be itcontent providers, broadcasters, network

providers or equipment manufacturers.

In 2000, after over two years of requirementcapture inDigiTAG (Digital Television Action

Group) EACEM (European Association of Consumer Electronic s Manufacturers), which has

evolved into EICTA (European Information, Communications and Consumer Electronics

Technology Industry Associations), decided to address this situation by developing a basic

specification as a minimum platform, providing secure reception ofbroadcast content and

associated services. This resulted in the first revision ofthis standard. It has been used as a

basis in many countries to deploy Digital Terrestrial TV (DTT) with great success.

In 2007, with a new wave of High Definition servicesbeing considered to be launched due to

theavailabilityof MPEG4 components, EICTA and the French “Forum HD” decided to

collaborate to create an update for High Definition, and make some minor adjustments that

were due after 7 years of practice with Standard Definition terrestrial TV in the market.The

new standard improvements are taking into account contributions and comments from a.o. UK

DTG (draft HDD-Book), Nordig and DGTVi. This standard does not yet address new

generations of channel coding (DVB-T2) now being consideredby DVB. Extensions of this

standard in this domain may be foreseen in the future.

DIGITAL TERRESTRIAL TELEVISION RECEIVERS

FOR THE DVB-T SYSTEM

1 Scope and object

This International Standard specifies both Standard Definition and High Definitionreceivers

for the DVB-T system.

It concerns:

• broadcasters, and

• receivermanufacturers.

The objective isto define:

• howto provide broadcasts that are understood by all receivers and enable receivers to

provide goodfacilitiesto their users;

• thebehaviour required from receivers towork well with these broadcasts and tobe

attractive to consumers.

To avoid doubt, the words “shall”, “should”, etc. are used i n the traditional way to distinguish

issues that aremandatory versus those that are optional A baseline receiver will support the

mandatory features but not all the optionalfeatures in this standard. Inclusion of optional

features is partof the marketing strategyofthe manuf acturer.

Subtitling and teletext are considered to be components of TV services.Standalone teletext

services (without associated video content) are not part of thisstandard.

This standardprimarily addresses terrestrial delivery of digital transmissions.

This standard primarily addresses deployment in countriesthat use European Latin script

based languages.

Two types of systems are considered:

• standard systems where services are all SD and usewell-established codecs. Standard

receivers which can decode standard services are suitable for these systems;

• advanced systems where some services mayuse advanced codecs, for example to

provide HD video. Advanced receiverswhich can decode advanced services are suitable

for these systems.

Where the term “receiver” or “broadcast” is used without aqualifier, the statement is

applicable equally to both types of systems.
