FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62516-1 has been prepared by technical area 1: Terminals for

audio, video and data services and content, of IEC technical committee 100: Audio, video and

multimedia systems and equipment.

4 Summary of receiver implementation
4.1 General

This part of IEC 62516 provides the characteristics and minimum required performance

specifications necessary in implementing T-DMB receivers in order to minimize flaws due to

misunderstandings of the relevant standard. This clause provides just a summary of this

specification. Normative characteristics and requirements are provided in detail in Clauses 5

to 10.
4.2 Basic operation of a T-DMB transmitter

As shown in Figure 1 the T-DMB system is an extension of the existing DAB system by adding

a video multiplexer before the stream mode channel.

Figure 2 shows the conceptual structure of the video multiplexer including an IOD generator

that provides the information on system initialization, an OD/BIFS generator that provides

information on scene composition using objects, and AV encoders that generate audio/video

compressed streams. The IOD, OD, BIFS, compressed AV data, and auxiliary data are

packetized and multiplexed into a RS-coded MPEG-2 TS. The RS code is included here for

maintaining the multiplexed video data at a higher quality than those of existing DAB signals.

For each of the video, audio, and data services provided by the video multiplexer in Figure 2,

this standard specifies characteristics and requirements that are needed in implementing a

receiver that supports such services.

4.3 Functional requirements

Information on receiver implementations is provided on a technical basis by the descriptions

and requirements on the items needed for the implementation of T-DMB receivers.

Various operational situations are defined such as service switching situations within an

ensemble and between ensembles.
4.4 Summary of audio service

In this standard, the audio service is related to the implementation of a receiver compatible

with the DAB audio, i.e. MUSICAM. For the audio service, IEC 62104 can be referred to

without making any further specifications. IEC 62104 classifies system functions, performance

requirements, interfaces, minimum performance specifications and its measurement method

and gives as requirements audio decoder, automatic mode selection, service selection,

receiver operation on multiplex reconfiguration, automatic switching to another ensemble, etc.

It has specifications for each of the interfaces that are divided into RF inputs, analog and

digital audio interfaces, and coded audio interfaces. For minimum performance specifications

and measurement methods, it specifies bit-error ratio (BER), selectivity, minimum input

power, sensitivity with their measurement methods.

Mandatory characteristics and requirements for T-DMB and audio services are described in

5.1 and 5.2.

4.5 Summary of video service

In this standard, the video service is defined as in the T-DMB standards, i.e. ETSI TS 102 427

and ETSI TS 102 428, and is related to the implementation of a receiver compatible with a

service composed of a video (H.264), audio (BSAC or HE-AAC V2) and multimedia data

(BIFS, Images) in stream mode.

Clause 5 gives additional requirements to those already specified in ETSI TS 102 427 and

ETSI TS 102 428. Clause 6 explains the timing information related to the AV synchronization.

Clauses 7, 8, and 9 define requirements for video decoders, audio decoders, and BIFS,

respectively.
4.6 Summary of data service

The data service is related to the implementation of a receiver compatible with the T-DMB

data services including MOT slideshow and broadcast website service that use MOT,

transparent data channel, and IP datagram tunnelling protocols. The data service is outside

the scope of this document.
5 Requirements on receiver implementations
5.1 T-DMB service selection and basic requirements

The main service channel and the fast information channel (FIC) deliver service components

and MCI, respectively. A service is composed of one or more service components and

multiple services can be delivered in an ensemble.

Users of T-DMB receivers get access to a service component by selecting a service. Primary

component is a mandatory service component in a service, whereas the other remaining

service components are secondary components. These two components should be
distinguished.
A T-DMB receiver shall meet the following basic requirements:

– a T-DMB receiver shall appropriately process the MCI for the access to the service

desired;

– a T-DMB receiver shall abide by the terms in ETSI TR 101 496-2 regarding multiplex

reconfiguration;
– a T-DMB receiver sh
