Abstract: Изобретение относится к области кодирования/декодирования, в частности к кодированию в интра-режиме стандарта Высокоэффективного Кодирования Видеосигнала (HEVC). Техническим результатом является повышение эффективности кодирования/декодирования информации о режимах предсказания. Предложен вывод опорных значений режима предсказания, также называемых наиболее вероятными режимами (MPM), которые применяются для кодирования/декодирования режима предсказания, связанного с текущим элементом кодирования. Первое и второе опорные значения режима предсказания выводятся из соответствующих режимов предсказания по меньшей мере двух соседних элементов кодирования текущего элемента кодирования. Первый и второй опорные режимы предсказания отличаются друг от друга, а третье опорное значение режима предсказания выводится из первого и второго опорных значений режима предсказания. При этом первое - третье опорные значения режима внутреннего предсказания используют для кодирования или декодирования значения режима, подлежащего кодированию или декодированию. Посредством вывода трех MPM вместо двух для сравнения с режимом предсказания текущего блока кодирования эффективность кодирования улучшается, поскольку происходит увеличение вероятности того, что режим предсказания текущего блока кодирования соответствует одному из выведенных наиболее вероятных режимов. 10 н. и 15 з.п. ф-лы, 11 ил.
