标准范围
本推荐性国际标准规定了框架、概念、测试方法以及声称符合Rec所需达到的标准。ITU-T T.800 ISO/IEC 15444-1或建议。ITU-T T.814 ISO/IEC 15444-15。它为指定抽象测试套件（ATSs）和定义一致性测试期间要遵循的过程提供了一个框架。本推荐国际标准:？指定使用Rec进行编码和解码的合规性测试过程。ITU-T T.800 ISO/IEC 15444-1和建议。ITU-T T.814 ISO/IEC 15444-15；？指定要与测试过程一起使用的码流、解码图像和错误度量；？指定ATSs？为创建编码器符合性测试提供指导本推荐性国际标准不包括以下试验:-验收测试:确定实现是否满足验收标准并使用户能够确定是否接受该实现的过程。这包括计划和执行证明实现满足用户需求的几种测试（例如，功能、质量和速度性能测试）。-性能测试:在各种条件下测量被测实现（IUT）的性能特征，例如其吞吐量和响应性。-稳健性测试:确定实现如何处理包含错误的数据的过程。
This Recommendation International Standard specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim compliance to Rec. ITU-T T.800 ISO/IEC 15444-1 or Rec. ITU-T T.814 ISO/IEC 15444-15. It provides a framework for specifying abstract test suites (ATSs) and for defining the procedures to be followed during compliance testing.
This Recommendation International Standard:
？ specifies compliance testing procedures for encoding and decoding using Rec. ITU-T T.800 ISO/IEC 15444-1 and Rec. ITU-T T.814 ISO/IEC 15444-15;
？ specifies codestreams, decoded images, and error metrics to be used with the testing procedures;
？ specifies ATSs;
？ provides guidance for creating an encoder compliance test
This Recommendation International Standard does not include the following tests:
- Acceptance testing: the process of determining whether an implementation satisfies acceptance criteria and enables the user to determine whether or not to accept the implementation. This includes the planning and execution of several kinds of tests (e.g., functionality, quality, and speed performance testing) that demonstrate that the implementation satisfies the user requirements.
- Performance testing: measures the performance characteristics of an implementation under test (IUT) such as its throughput and responsiveness, under various conditions.
- Robustness testing: the process of determining how well an implementation processes data which contains errors.
