| 用于视频信号类型识别的独立于编码的代码点 |
ITU-T H.273（ex H.STI）建议书定义了用以确定视频（或静止图像）呈现属性并独立于压缩编码和比特率的不同代码点和字段。这些属性可以描述对解码数据所做的相关说明，同样也能够在适用于压缩这一输入信号的编码器进行信号压缩前，描述这一信号的特性。该建议书是作为对应ISO / IEC 23001-8 2016号文件及其修正1的一部分，与ISO/IEC JTC 1 SC 29/WG 11（MPEG）协作编写的双文本建议书。该建议书将作为技术匹配的姊妹文件，由两个机构（ITU-T和ISO/IEC）共同发布。 |

| Observation: | ITU-T H.273 (2016) was published as a twin text technically aligned with ISO/IEC 23001-8:2016 and its Amendment 1. After ISO/IEC 23001-8:2016 was split into three parts in 2019 and renumbered as ISO/IEC 23091 parts 1, 2 and 3, ITU-T H.273 remained technically aligned to ISO/IEC 23091-2:2019. |
