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
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.
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
_ test purpose;
_ objects and procedures which are to be used to test one or more MHEG-5 features;
_ expected result.
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
A test suite for an Application Domain shall be generated by using the PICS template in subclause 9.2.1 PICS
