Foreword
This ETSI Technical Report (ETR) has been produced under the authority of the Joint Technical
Committee (JTC) of the European Broadcasting Union (EBU), Comité Européen de Normalisation
ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI).
This ETR is based on the DVB document A001 revision 2, dated July 1997, and it may be converted into
an ETS after market feedback. For this purpose, the wording of an ETS rather than an ETR is used.
ETRs are informative documents resulting from ETSI studies which are not appropriate for European
Telecommunication Standard (ETS) or Interim European Telecommunication Standard (I-ETS) status. An
ETR may be used to publish material which is either of an informative nature, relating to the use or the
application of ETSs or I-ETSs, or which is immature and not yet suitable for formal adoption as an ETS or
an I-ETS.
NOTE: The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of standards in
the specific field of broadcasting and related fields. Since 1995 the JTC became a
tripartite body by including in the Memorandum of Understanding also CENELEC,
which is responsible for the standardization of radio and television receivers. The EBU
is a professional association of broadcasting organizations whose work includes the
co-ordination of its members' activities in the technical, legal, programme-making and
programme-exchange domains. The EBU has active members in about 60 countries in
the European broadcasting area; its headquarters is in Geneva *.

Digital Video Broadcasting (DVB) Project
Founded in September 1993, the DVB Project is a market-led consortium of public and private sector
organizations in the television industry. Its aim is to establish the framework for the introduction of
MPEG-2 based digital television services. Now comprising over 200 organizations from more than
25 countries around the world, DVB fosters market-led systems, which meet the real needs, and
economic circumstances, of the consumer electronics and the broadcast industry.

ETR 154: September 1997
Introduction
This ETR presents guidelines covering coding and decoding using the MPEG-2 system layer, video
coding and audio coding as defined in ISO/IEC 13818-1 [1], ISO/IEC 13818-2 [2] and ISO/IEC 13818-3 [3]
respectively.
The guidelines presented in this ETR for the Integrated Receiver-Decoder (IRD) are intended to represent
a minimum functionality that all IRDs of a particular class are required to either meet or exceed. It is
necessary to specify the minimum IRD functionality for basic parameters, if broadcasters are not to be
prevented from ever using certain features. For example, if a significant population of IRDs were produced
that supported only the Simple Profile, broadcasters would never be able to transmit Main Profile bit-
streams.
IRDs are classified in three dimensions as:
- "25 Hz" or "30 Hz", depending on whether the nominal video frame rates based on 25 Hz or
30000/1001 Hz (approximately 29,97 Hz) are supported. It is expected that 25 Hz IRDs will be used
in those countries where the existing analogue TV transmissions use 25 Hz frame rate and 30 Hz
IRDs will be used in countries where the analogue TV transmissions use 30000/1001 Hz frame
rate. There are also likely to be "dual-standard" IRDs which have the capabilities of both 25 Hz and
30 Hz IRDs.
- "SDTV" or "HDTV", depending on whether or not they are limited to decoding pictures of
conventional TV resolution. The capabilities of an SDTV IRD are a sub-set of those of an HDTV
IRD.
- "with digital interface" or "Baseline", depending on whether or not they are intended for use with a
digital bitstream storage device such as a digital VCR. The capabilities of a Baseline IRD are a sub-
set of those of an IRD with digital interface.
To give a complete definition of an IRD, all three dimensions need to be specified, e.g. 25 Hz SDTV
Baseline IRD.
It should be noted that in DVB systems the source picture format, encoded picture format and display
picture format do not need to be identical. For example, HDTV source material may be broadcast as an
SDTV bitstream after down-conversion to SDTV resolution and encoding within the constraints of Main
Profile at Main Level. The IRD receiving the bitstream may then up-convert the decoded picture for display
at HDTV resolution. With suitable down-conversion and up-conversion, the quality of the resultant HDTV
picture may be close to that of the original HDTV source.
Another notable feature of the DVB system is that a single Transport Stream (TS) may contain
programme material intended for more than one type of IRD. A typical example of this is likely to be the
simulcasting of SDTV and HDTV video material. In this case an SDTV IRD will decode and display SDTV
pictures whilst an HDTV IRD will decode and display HDTV pictures from the same TS.
Where a feature described in this ETR is mandatory, the word "shall" is used and the text is in italic; all
other features are optional. The functionality is specified in the form of constraints on MPEG-2 systems,
video and audio which the IRDs are required to decode correctly.
The specification of these baseline features in no way prohibits IRD manufacturers from including
additional features, and should not be interpreted as stipulating any form of upper limit to the performance.
The guidelines do not cover features, such as the IRD's up-sampling filter, which affect the quality of the
displayed picture rather than whether the IRD is able to decode pictures at all. Such issues are left to the
marketplace.
The guidelines presented for IRDs observe the following principles:
- wherever practical, IRDs should be designed to allow for future compatible extensions to the bit-
stream syntax;
- all "reserved" and "private" bits in MPEG-2 systems, video and audio should be ignored by IRDs not
designed to make use of them.

ETR 154: September 1997
The rules of operation for the encoders are features and constraints which the encoding system should
adhere to in order to ensure that the transmissions can be correctly decoded. These constraints may be
mandatory or optional. Where a feature or constraint is mandatory, the word "shall" is used and the text is
italic; all other features are optional.
Clauses 4 to 6 provide the guidelines for the Digital Video Broadcasting (DVB) systems layer, video and
audio respectively. For information, some of the key features are summarized below, but clauses 4 to 6
should be consulted for all definitions:
Systems:
- MPEG-2 TS is used;
- Service Information (SI) is based on MPEG-2 program-specific information;
- scrambling is as defined in ETR 289 [5];
- conditional access uses the MPEG-2 Conditional Access CA_descriptor;
- Partial TSs are used for digital VCR applications.
Video:
- MPEG-2 Main Profile at Main Level is used for SDTV;
- MPEG-2 Main Profile at High Level is used for HDTV;
- the 25 Hz SDTV IRD supports 25 Hz frame rate;
- the 25 Hz HDTV IRD supports frame rates of 25 Hz or 50 Hz;
- the 30 Hz SDTV IRD supports frame rates of 24000/1001, 24, 30000/1001 and 30 Hz;
- the 30 Hz HDTV IRD supports frame rates of 24000/1001, 24, 30000/1001, 30, 60000/1001 and
60 Hz;
- SDTV pictures may have either 4:3, 16:9 or 2.21:1 aspect ratio; IRDs support 4:3 and 16:9 and
optionally 2.21:1 aspect ratio;
- HDTV pictures have 16:9 or 2.21:1aspect ratio; IRDs support 16:9 and optionally 2.21:1 aspect
ratio;
- IRDs support the use of pan vectors to allow a 4:3 monitor to give a full-screen display of a 16:9
coded picture of SDTV resolution.
Audio:
- MPEG-2 Layer I and Layer II is supported by the IRD;
- the use of Layer II is recommended for the encoded bit-stream;
- IRDs support single channel, dual channel, joint stereo, stereo and the extraction of at least a
stereo pair from MPEG-2 compatible multi-channel audio;
- sampling rates of 32 kHz, 44,1 kHz and 48 kHz are supported by IRDs;
- the encoded bit-stream does not use emphasis.

1 Scope
This ETSI Technical Report (ETR) provides implementation guidelines for the use of MPEG-2 audio-visual
coding in satellite, cable and terrestrial broadcasting distribution systems. Both Standard Definition
Television (SDTV) and High Definition Television (HDTV) are covered. Guidelines for devices equipped
with a digital interface intended for digital VCR applications are also given in this ETR. It does not cover
applications such as contribution services which are likely to be the subject of subsequent "Guidelines"
documents.
The rules of operation for the encoders are features and constraints which the encoding system should
adhere to in order to ensure that the transmissions can be correctly decoded. These constraints may be
mandatory, recommended or optional.

4 Systems layer
This clause describes the guidelines for encoding the systems layer of MPEG-2 in DVB broadcast
bit-streams, and for decoding this layer in the IRD. The source bitstream may be transmitted via a
satellite, cable or terrestrial channel, or via a digital interface. Subclause 4.1 applies to the encoding of all
source bitstreams and their decoding by a Baseline IRD. Subclause 4.2 gives specific information relating
to bitstreams transmitted via a digital interface intended for VCR applications and decoding by IRDs
equipped with such an interface.
4.1 Broadcast bitstreams and Baseline IRDs
The multiplexing of baseband signals and associated data conforms to ISO/IEC 13818-1 [1]. Some of the
parameters and fields are not used in the DVB System and these restrictions are described below. To
allow full compliance to ISO/IEC 13818-1 [1] and upward compatibility with future enhanced versions, a
DVB IRD shall be able to skip over data structures which are currently "reserved", or which correspond to
functions not implemented by the IRD. As an example of this capability, a descriptor tag not yet defined
within the DVB System shall be interpreted as a no-action tag, its length field correctly decoded and
subsequent data skipped.
For the same reason, IRD design should be made under the assumption that any legal structure as
permitted by ISO/IEC 13818-1 [1] may occur in the broadcast stream even if presently reserved or
unused. Therefore the following is assumed:
- private data shall only be acted upon by decoders which are so enabled;
- filling out the bit-stream shall be carried out using the normal stuffing mechanism. Reserved fields
shall not be used for this purpose. Data of reserved fields shall be set to 0xFF.
The headings below in this clause are based on ISO/IEC 13818-1 [1]. The numbers in brac
