Abstract

Схемы шумоподавления в устройстве компрессии видеосигнала типа компрессии с дифференциальной импульсно-кодовой модуляцией (DPCM) с предсказанием содержат простой элемент нелинейной обработки (500) в системе DPCM (12, 15, 16, 18, 1333) для исключения остатков между предсказанными и реальными сигналами изображения, которые меньше, чем предварительно определенное значение. Исключение таких остатков резко уменьшает количество уплотненных данных, порожденных для сигналов, содержащих даже самые умеренные количества шума.
