ISO/IEC 23008-5:2017提供了随附的参考软件，作为电子附件，用于记录ITU-T H.265 | ISO/IEC 23008-2。该软件是本文件不可分割的一部分。 根据建议ITU-T H.265 | ISO/IEC 23008-2，编码器或解码器的实现不需要使用该参考软件。建议ITU-T H.265 | ISO/IEC 23008-2中确定的要求优先于参考软件的行为。

ISO/IEC 23008-5:2017 provides accompanying reference software for Rec. ITU-T H.265 | ISO/IEC 23008-2 as an electronic attachment. The software is an integral part of this document. The use of this reference software is not required for making an implementation of an encoder or decoder in conformance to Rec. ITU-T H.265 | ISO/IEC 23008-2. Requirements established in Rec. ITU-T H.265 | ISO/IEC 23008-2 take precedence over the behaviour of the reference software.
