ISO/IEC 13818-4:2004规定了如何设计测试，以验证编码数据和解码器是否符合ISO/IEC 13818第1、2、3和7部分中规定的要求。 ISO/IEC 13818第1、2、3和7部分定义了编码数据和解码器的特性。解码器的功能通过定义可在编码数据中利用的标准子集，指定解码器可解码和重构的编码数据。如果编码数据的特性在解码器功能指定的标准子集内，则解码器可以对编码数据进行解码。 描述了测试编码数据和解码器是否符合ISO/IEC 13818第1、2、3和7部分规定要求的程序。鉴于所要求的一系列特性，ISO/IEC 13818第1、2、3和7部分完全确定了必须满足的要求。ISO/IEC 13818-4: 2004年总结了需求，交叉引用了它们的特征，并定义了如何测试与它们的一致性。 ISO/IEC 13818-4:2004的电子附件中提供了一组根据这些指南实施的一致性测试序列。

ISO/IEC 13818-4:2004 specifies how tests can be designed to verify whether coded data and decoders meet requirements specified in parts 1, 2, 3 and 7 of ISO/IEC 13818. Characteristics of coded data and decoders are defined for parts 1, 2, 3 and 7 of ISO/IEC 13818. The capabilities of a decoder specify which coded data the decoder can decode and reconstruct, by defining the subset of the standard that may be exploited in the coded data. Coded data can be decoded by a decoder if the characteristics of the coded data are within the subset of the standard specified by the decoder capabilities. Procedures are described for testing conformance of coded data and decoders to the requirements defined in parts 1, 2, 3 and 7 of ISO/IEC 13818. Given the set of characteristics claimed, the requirements that must be met are fully determined by parts 1, 2, 3 and 7 of ISO/IEC 13818. ISO/IEC 13818-4:2004 summarizes the requirements, cross references them to characteristics, and defines how conformance with them can be tested. A set of conformance test sequences implemented according to those guidelines are provided as an electronic annex to ISO/IEC 13818-4:2004.
