Super Hi-Vision становится стандартом26.08.2012 |
|
Международный союз электросвязи (МСЭ) утвердил в качестве перспективного телевизионного стандарта опробованную во время лондонской Олимпиады разработку японской телекомпании NHK. Super Hi-Vision, иначе называемый еще UHD и 8К, утвержден после консультаций с другими национальными телевещательными корпорациями, которые согласны с предложенными японской компанией техническими решениями. Super Hi-Vision позволяет передавать изображение с разрешением 7680 на 4320 пикселей со скоростью 60 кадров в секунду, хотя NHK надеется довести частоту до 120 кадров в секунду. 8K поддерживает как 10, так и 12 битное кодирование цвета, что дает лучшие градации цвета и расширенную цветовую гамму, позволяя воспроизводить более интенсивные и естественные цвета. На графике слева показана цветовая гамма зрения человека. Маленький треугольник представляет сегодняшнюю стандартную цветовую гамму телевизоров, а большой треугольник показывает цветовую гамму стандарта 8K Несмотря на принятие стандарта, он вряд ли появятся в жилых помещениях в ближайшем будущем, так NHK не собирается начинать внедрение Super Hi-Vision до 2020 года.
