标准摘要
[中文适用范围]： 指定 ITU-T Rec.T.81 (ISO/IEC 10981-1) 编码和解码过程的规范性合规性测试。 这些合规性测试适用于 ITU-T Rec.T.81 (ISO/IEC 10918-1) 中规定的一种或多种编码和解码过程的“独立”通用实现。 这些测试的目的包括通用编码器（和解码器）实现以足够的精度计算离散余弦变换 (DCT) 和量化函数。 [外文原描述]： Specifies normative compliance tests for the ITU-T Rec.T.81 (ISO/IEC 10981-1) encoding and decoding processes. These compliances tests are applicable to "stand-alone" generic implementations of one or more of the encoding and decoding processes specified in ITU-T Rec.T.81 (ISO/IEC 10918-1). The purposes of these tests include that generic encoder (and decoder) implementations compute the discrete cosine transform (DCT) and quantization functions with sufficient acccuracy.
