ISO/IEC 14496-4:2004规定了如何设计测试，以验证比特流和解码器是否满足ISO/IEC 14496（第1、2和3部分）和ISO/IEC 14496-6:2000规定的要求。它规定了如何以符合ISO/IEC 14496（第1、2和3部分）的可互操作透明方式，为各种传输技术上的比特流传输设计测试。编码器并没有被特别提到。如果编码器生成符合ISO/IEC 14496（第1、2和3部分）中规定的语法和语义比特流要求的比特流，则可以将其称为ISO/IEC 14496编码器。 描述了测试比特流和解码器是否符合ISO/IEC 14496（第1、2和3部分）中定义的要求的程序。 鉴于所声称的一系列特性，必须满足的要求完全由ISO/IEC 14496（第1、2和3部分）确定。ISO/IEC 14496-4:2004总结了这些要求，将其与特性交叉引用，并定义了如何测试符合性。给出了构造测试以验证比特流和解码器一致性的指南。ISO/IEC 14496-4:2004给出了如何构建比特流测试套件以检查或验证解码器一致性的指南。此外，根据这些指南实施的一些测试比特流作为ISO/IEC 14496-4:2004的电子附件提供。这些测试比特流记录在ISO/IEC 14496-4:2004的各个章节中。ISO/IEC 14496中定义了会话和信道建立的过程和信令消息- 6:2000. 符合ISO/IEC 14496-4:2004中的信令消息和程序是根据ISO/IEC 14496-6:2000中的规范定义的。本规范允许制造商在静态审查中确定信令消息的一致性，并提供抽象测试用例，以在ISO/IEC 9646（所有部分）一致性测试系列标准中定义的实施动态审查中测试程序的一致性。

ISO/IEC 14496-4:2004 specifies how tests can be designed to verify whether bitstreams and decoders meet requirements specified in ISO/IEC 14496 (parts 1, 2 and 3) and for ISO/IEC 14496-6:2000. It specifies how tests can be designed for bitstream delivery over various delivery technologies in an interoperable transparent manner to ISO/IEC 14496 (parts 1, 2 and 3). Encoders are not addressed specifically. An encoder may be said to be an ISO/IEC 14496 encoder if it generates bitstreams compliant with the syntactic and semantic bitstream requirements specified in ISO/IEC 14496 (parts 1, 2 and 3). Procedures are described for testing conformance of bitstreams and decoders to the requirements defined in ISO/IEC 14496 (parts 1, 2 and 3). Given the set of characteristics claimed, the requirements that must be met are fully determined by ISO/IEC 14496 (parts 1, 2 and 3). ISO/IEC 14496-4:2004 summarizes the requirements, cross references them to characteristics and defines how conformance with them can be tested. Guidelines are given on constructing tests to verify bitstream and decoder conformance. ISO/IEC 14496-4:2004 gives guidelines on how to construct bitstream test suites to check or verify decoder conformance. In addition, some test bitstreams implemented according to those guidelines are provided as an electronic annex to ISO/IEC 14496-4:2004. These test bitstreams are documented in the various sections of ISO/IEC 14496-4:2004. The procedures and signaling messages for session and channel establishment are defined in ISO/IEC 14496-6:2000. Conformance with the signaling messages and procedures in ISO/IEC 14496-4:2004 are defined in accordance with the specifications in ISO/IEC 14496-6:2000. This specification allows the manufacturer to identify the conformance of the signaling message in a static review and provides abstract test cases to test the conformance to the procedures in a dynamic review of an implementation as defined in ISO/IEC 9646 (all parts), the Conformance Testing series of standards.
