Technologies de l'information — Codage de l'information multimédia et hypermédia — Partie 7: Essais d'interopérabilité et de conformité pour l'ISO/CEI 13522-5

1.1 Context of the scope

ISO/IEC 13522 specifies the coded representation of multimedia/hypermedia information objects (MHEG objects)

for interchange as final form units within or across services and applications, by any means of interchange

including local area networks, wide area telecommunication or broadcast networks, storage media, etc.

ISO/IEC 13522-5:1997 defines the MHEG-5 object classes for interchange and use in base-level applications

intended to be run on limited resource terminals such as set-top-boxes in such contexts as interactive broadband

services.

Annex F of ISO/IEC 13522-5:1997 specifies the features that need to be defined by a specific MHEG-5 application

domain. The informative annexes of this part of ISO/IEC 13522-5:1997 give illustrative examples of profiles of

some common application domains.

1.2 Scope

MHEG-5 engines are system or application components that handle, interpret and present MHEG-5 objects. The

scope of this part of ISO/IEC 13522 is to define a test suite that can be used to test an MHEG-5 engine's

conformance to a specific application domain. It also defines a format for test cases that can be used to extend the

test suite, either for more detailed testing or for extensions defined by the application domain.

It is beyond the scope of this part of ISO/IEC 13522 to define tests for engine performance, engine memory usage

or for MHEG-5 applications that run on these engines.

This part of the ISO/IEC 13522 specifies test cases for all features of ISO/IEC 13522-5:1997. Application domains

define a subset of MHEG-5 features that must be supported. In order to test conformance to a specific application

domain, a corresponding subset of the test cases must be defined. This subset of the test suite is then used to test

the conformance of the engine.

This part of ISO/IEC 13522 tests conformance of the behaviour of an MHEG engine. It does not validate the

physical presentation of MHEG-5 objects.

The test suite comprises a set of test cases and a corresponding set of test objects. The test cases are defined in

terms of:

_ test purpose;

_ objects and procedures which are to be used to test one or more MHEG-5 features;

_ expected result.

ISO/IEC 13522-7:2001(E)

A set of content data will be provided for the test objects. These content data are intended as a guide for

generating a test suite and should be converted or replaced by content formats appropriate to the Application

Domain.

A test suite for an Application Domain shall be generated by using the PICS template in subclause 9.2.1 PICS

Template.
