标准范围

ISO/IEC 23002:2008规定了整数输出8x8反离散余弦变换(IDCT)的特定实现方式,其完全符合ISO/IEC 23002-1中规定的精度要求,并且还满足或超过了许多国际视频编码标准中为IDCT精度规定的所有精度要求。它还提供了基于相同因子分解结构的整数输出8x8前向DCT的(非规范性)规范。

ISO/IEC 23002-2:2008 specifies a particular implementation of an integer-output 8x8 inverse discrete cosine transform (IDCT) that fully conforms to the accuracy requirements specified in ISO/IEC 23002-1 and additionally meets or exceeds all accuracy requirements specified for IDCT precision in a number of international video coding standards. It additionally provides a (non-normative) specification of an integer-output 8x8 forward DCT based on the same factorization structure.
