Abstract

Устройство генерирует в боксе-контейнере файла для хранения видеоконтента бокс SampleGroupDescription, который предоставляет описание группы выборок для группирования выборок. Бокс SampleGroupDescription включает в себя элемент синтаксиса типа группирования с конкретным значением. Дополнительно бокс SampleGroupDescription включает в себя одну или более записей группы выборок. Устройство генерирует в том же самом боксе-контейнере множество боксов SampleToGroup. Каждый соответствующий бокс SampleToGroup из множества боксов SampleToGroup включает в себя соответствующий элемент синтаксиса типа группирования с конкретным значением, включает в себя соответствующий элемент синтаксиса счетчика выборки, указывающий количество выборок в соответствующем группировании выборок, и включает в себя соответствующий элемент синтаксиса индекса описания группы, указывающий индекс записи в боксе SampleGroupDescription, которая описывает выборки соответствующего группирования выборок. Каждая выборка соответствующего группирования выборок содержит соответствующую картинку видеоконтента.
