IEC 62516-3:2013

Terrestrial digital multimedia broadcasting (T-DMB) receivers - Part 3: Common API

IEC 62516-3:2013 describes the T-DMB common application program interface (API). It provides a software platform that, when combined with the T-DMB O/S, forms a universal interface for application programs. This interface allows application programs to be written in such a way that they run on any T-DMB receiver unit, as described in IEC 62516-1:2009 and IEC 62516-2:2011 regardless of its manufacturer. It also defines a software environment that allows multiple application programs to be interoperable on a single receiver unit by sharing the fixed resources of the receiver, and it provides a set of interfaces that the T-DMB middleware and the ASIC specific software use.

Récepteurs pour diffusion multimédia numérique terrestre (T-DMB) - Partie 3: API commune

La CEI 62516-3:2013 décrit l'interface de programmation d'application (API) commune T-DMB. Elle fournit une plate-forme logicielle qui, lorsqu'elle est combinée avec le système d'exploitation O/S T-DMB, constitue une interface universelle pour les programmes d'application. Cette interface permet d'écrire des programmes d'application de telle manière qu'ils puissent être exécutés sur n'importe quelle unité de récepteur T-DMB, comme décrit dans les CEI 62516-1:2009 et CEI 62516-2:2011 quel que soit son fabricant. Elle définit également un environnement logiciel permettant à plusieurs programmes d'application d'être interopérables sur une unité de récepteur unique, en partageant les ressources fixes du récepteur. Elle fournit également un ensemble d'interfaces utilisées par l'intergiciel T-DMB et le logiciel spécifique à un ASIC (Circuit intégré à application spécifique).

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 62516-3 has been prepared by technical area 1: Terminals for
audio, video and data services and contents, of IEC technical committee 100: Audio, video
