| Не зависящие от метода кодирования кодовые точки для идентификации типа видеосигнала |
В Рекомендации МСЭ-T H.273 определены различные кодовые точки и поля, которые устанавливают свойства видеоизображения (или неподвижного изображения) и не зависят от метода кодирования при сжатии и битовой скорости. Указанные свойства могут служить целям надлежащей интерпретации декодированных данных или, аналогичным образом, описания характеристик такого сигнала перед сжатием сигналов кодером, подходящим для сжатия этого входного сигнала. Текст разработан как идентичный текст Рекомендации, соответствующий точкам видеокода в ИСО/МЭК 23001-8:2016 и Поправке 1 к нему, в сотрудничестве с ОТК 1 ПК 29/РГ 11 ИСО/МЭК (MPEG). Он будет опубликован обеими организациями (МСЭ-Т и ИСО/МЭК) как технически согласованный идентичный текст. |

| 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. |
