1.1范围的背景 ISO/IEC 13522规定了多媒体/超媒体信息对象(MHEG对象)的编码表示 通过任何交换方式，在服务和应用程序内或跨服务和应用程序作为最终表单单元进行交换 包括局域网、广域网或广域网、存储介质等。 ISO/IEC 13522-5:19 97定义了MHEG-5对象类，用于交换和在基础级应用中的使用 旨在在诸如交互式宽带之类的上下文中运行在诸如机顶盒之类的有限资源终端上 服务。 ISO/IEC 13522-5:19 97附录F规定了特定MHEG-5应用程序需要定义的特性 域。ISO/IEC 13522-5:19 97这一部分的信息性附件给出了说明性示例 一些常见的应用领域。1.2范围 MHEG-5引擎是处理、解释和呈现MHEG-5对象的系统或应用组件。The ISO/IEC 13522这一部分的范围是定义可用于测试MHEG-5发动机的测试套件 符合特定的应用领域。它还为测试用例定义了一种格式，该格式可用于扩展 测试套件，用于更详细的测试或由应用程序域定义的扩展。 定义发动机性能、发动机内存使用的测试超出了ISO/IEC 13522本部分的范围 或用于在这些引擎上运行的MHEG-5应用程序。 ISO/IEC 13522的这一部分规定了ISO/IEC 13522-5:19 97所有特性的测试用例。应用程序域 定义必须支持的MHEG-5功能的子集。为了测试与特定应用的一致性 域中，必须定义相应的测试用例子集。然后使用测试套件的这个子集来测试 发动机的一致性。 ISO/IEC 13522的这一部分测试MHEG发动机行为的一致性。它不验证 MHEG-5物体的物理呈现。 测试套件包括一组测试用例和一组相应的测试对象。测试用例定义在 条款: _测试目的； _用于测试一个或多个MHEG-5特征的对象和程序； _预期结果。 ISO/IEC 13522-7:20 01(E) 将为测试对象提供一组内容数据。这些内容数据旨在作为 生成测试套件，并应转换为适合应用程序的内容格式或替换 域。 应用程序域的测试套件应使用子条款9.2.1 PICS中的PICS模板生成 模板。

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.
