Abstract

Для заданного изображения в наборе изображений получают остаточные данные, которые могут быть использованы декодером для восстановления первого представления заданного изображения с первым уровнем качества с использованием второго представления заданного изображения с первым уровнем качества. Второе представление основано на представлении заданного изображения со вторым, более низким уровнем качества. Данные конфигурации, относящиеся к обработке остаточных данных, генерируются и выводятся для обработки с помощью декодера. Данные конфигурации содержат параметр (754, 854) временной обработки, который определяет степень временной обработки, связанной с восстановлением, для заданного изображения, первого представления с использованием второго представления и остаточных данных, причем выполнение временной обработки включает использование данных, основанных на множестве изображений в наборе изображений.
