22015-09-16. НАСА решило запустить UHD канал.
НАСА объявило о запуске первого в мире некоммерческого спутникового канала в UHD качестве. В качестве партнеров в данном проекте компанию агентству составили SES и Harmonic. В соответствии с пресс-релизом агенства новый канал будет доступен не только в спутниковых сетях, но и в Интернет (требуется пропускная способность канала 13 мбит в сек.). Спутниковое вещание будет проходить при помощи космического аппарата AMC 18 (принадлежит компании SES).Тэги: Космическое агентство СШАSESHarmonicAMC 18
