Abstract

Раскрыт видеодекодер, который использует методы сокращения потребления энергии. Видеодекодер содержит: (а) энтропийный декодер, который декодирует битовый поток, определяющий упомянутое видео; (b) обратное преобразование, которое преобразовывает упомянутый декодируемый битовый поток; (с) модуль предсказания, который выборочно выполняет внутрикадровое предсказание и предсказание с компенсацией движения на основе упомянутого декодируемого битового потока; (d) буфер, содержащий сжатые данные изображения, используемые для упомянутого предсказания с компенсацией движения, включающие в себя данные с низким разрешением и данные с высоким разрешением, причем упомянутый модуль предсказания предсказывает и набор данных с низким разрешением, и набор данных с высоким разрешением на основе упомянутых данных с низким разрешением с использованием информации предсказания с высоким разрешением, декодируемой из упомянутого битового потока, без использования упомянутых данных высокого разрешения.
