Abstract
В примере раскрытие предусматривает прием кодированной видеопоследовательности, содержащей кодированные изображения видеопоследовательности, и прием параметров синхронизации для кодированной видеопоследовательности, которые включают в себя временную шкалу и число единиц в такте синхросигнала самое большее один раз в синтаксической структуре набора параметров видео (VPS), к которой обращается кодированная видеопоследовательность, и самое большее один раз, в части информации применимости видео (VUI) синтаксической структуры набора параметров последовательности (SPS), к которой обращается кодированная видеопоследовательность. Другой пример предусматривает кодирование изображений видеопоследовательности для того, чтобы генерировать кодированную видеопоследовательность, и сигнализирование параметров синхронизации для кодированной видеопоследовательности посредством, по меньшей мере, частичного сигнализирования временной шкалы и числа единиц в такте синхросигнала самое большее один раз в синтаксической VPS-структуре и самое большее один раз в VUI-части синтаксической SPS-структуры.
