| Coding-independent code points for video signal type identification |
 |
ITU-T H.273 defines various code points and fields that establish properties of a video (or still image) representation and are independent of the compression encoding and bit rate. These properties may describe the appropriate interpretation of decoded data or may, similarly, describe the characteristics of such signal before the signals compressed by an encoder that is suitable for compressing such an input signal. The text was developed as a twin text Recommendation corresponding to the video code points in ISO/IEC 23001-8:2016 and its Amendment 1 in collaboration with ISO/IEC JTC 1 SC 29/WG 11 (MPEG). It will be published as technically-aligned twin text by both organizations (ITU-T and ISO/IEC). |

| 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. |
