INTRODUCTION
Television has evolved over the last half century from an up-market entertainment medium to

becoming the major information tool around the world.

Television is available to virtually all people around the globe, be it individually or 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 to it instantly.

It is thus that the broadcasters and content providers set out to seek new means of delivering
higher levels of content, be it in volume or quality using existing or new transport mechanisms
available.
Digitalisation, taken from the world of information technology was the obvious choice.
It further brought the added benefits of efficient use of spectrum and energy, not to mention
interaction through a return path.
Terrestrial television has to migrate from analogue to digital in order to survive in the new
information society.
Without any doubt, all means of information and content dissemination technology will merge
over time, provided that sound business models find uptake by consumers at large.
Governments are keen to switch off the inefficient analogue broadcasts for a number of
obvious reasons, but only will be able to do so when consumers are confident that the new
proposition is attractive and affordable.
Business models are being developed to promote the uptake of digital receivers, however this
activity up to now is mainly led by private enterprises targeting the public sector willing to pay
for services in addition to those available from established public broadcasters.
This in itself is fine, but will not enable the migration from analogue to digital of all broadcasts,
however funded.
The more so as it has led to a variety of incompatible platforms tied to particular TV
operators, and this in turn does not allow for economy of scale for all parties concerned, be it
content providers, broadcasters, network providers or equipment manufacturers.

After over two years of requirement capture in DigiTAG (Digital Television Action Group) and
other fora, EACEM (European Association of Consumer Electronics Manufacturers) decided
to address this situation by developing a basic specification as a minimum platform, providing
secure reception of broadcast content and associated services. This includes both free to air
as well as pay TV services by means of the DVB common interface.

62216-1  IEC:2001(E) – 9 –
This is in order to provide a stable base from which new applications and services can be built
up, and ensuring backwards compatibility for products in the market based on this

specification, thus ensuring that the consumer will continue to receive the services they have

grown accustomed to.
EACEM has taken into consideration all other documents and specifications that were freely

available from various bodies (NorDig Group, ANIEL, etc.) in order to develop a pan European

specification.

DIGITAL TERRESTRIAL TELEVISION RECEIVERS

FOR THE DVB-T SYSTEM –
Part 1: Baseline receiver specification

1 Scope
This part of IEC 62216 specifies the baseline receiver for the DVB-T system.

It concerns:
• broadcasters, and
• receiver manufacturers.
The objective is to define:
• how to provide broadcasts that are understood by all receivers and enable receivers to
provide good facilities to their users;
• the behaviour required from receivers to work well with these broadcasts and to be
attractive to consumers.
To avoid doubt, the words “shall”, “should” etc. are used in the traditional way to distinguish
issues that are important versus those that are optional. The term “shall” is also used to
identify mandatory requirements that are inherited from other specifications that have greater
force.
This specification does not consider interactive applications and the data broadcasting that
would support them. Subtitling and teletext are considered to be components of TV services.
Standalone teletext services are not part of this standard.
This specification primarily addresses terrestrial delivery of digital transmissions.
This specification primarily addresses deployment in countries that use European Latin script
based languages.

4 Receiver capabilities
The list below gives a general overview of receiver capabilities supported by this
specification.
4.1 Frequency spectrum
• UHF and/or VHF (band III);
• 8 MHz and/or 7 MHz Channel bandwidth;
• supports all DVB-T modulation methods;
• supports both 2K and 8K transmitting methods;

• supports all code rates;
• supports all guard intervals;
• supports hierarchical mode by the demodulator;
• supports portability.
4.2 Conditional access
The receiver is capable of receiving free-to-air as well as pay services. In order to have the
necessary flexibility to choose a conditional access (CA) system one common interface slot
(according to EN 50221) is foreseen. In future, other means to add new CA systems might be
used such as the IEEE 1394 digital interface.
4.3 Return path
If a modem is not embedded then suitable means should be provided for connection to one
(for example RS 232) for further interactive applications (for example IPPV, …).

62216-1  IEC:2001(E) – 13 –
4.4 Navigator (SI)
The navigator will use the mandatory service information broadcast in the service information

table and the event information table to present appropriate service and event information to

the user and to allow automatic selection of service features when the user selects a service.

Details can be found in clause 9, which is based on (mandatory) DVB-SI rules.

4.5 Auto installation
The receiver will allow access to all receivable services and will use the mandatory
information in the NIT and/or SDT to automate the initialisation of the service list and

subsequent updates thereof. See also 9.4.2.
4.6 Teletext carried in digital streams
Support of this feature is the responsibility of the manufacturer. Manufacturers are prepared
to support teletext for a transition period. This feature and its signalling is described in
clause 11.
4.7 Analogue recording/copy management
Analogue recording via the peritelevision connector (EN 50049-1) is supported.
4.8 Services
The receiver shall support the following services and service features:
• free to air broadcast;
• multi-lingual sound, multi-comments;
• multi-lingual subtitles (DVB subtitles, region based graphics);
• audio broadcast;
• screen formatting for ratios of 4:3 and 16:9.
In addition, the receiver may support:
• teletext linked with a program;
• mosaic services;
• Automatic Format Descriptor (AFD) for flexible screen formatting.
4.9 Future versions of this specification
It is the intention to extend this specification in a backward compatible way towards new types
of services and service options and consequent receiver behaviour.
This is the case, in particular for the choice of an API, where it is currently expected that
DVB-MHP is an appropriate choice as a generally accepted API for broadly marketable
receivers.
In clause 9, the following additions are foreseen:
• Service list and logical channel number handling through the SDT as an additional
alternative to the
