Abstract

Даний опис описує способи для сигналізації режиму внутрішнього прогнозування для кодування відео. В одному прикладі відеокодер конфігурується, щоб визначити, для блока відеоданих, набір найбільш ймовірних режимів внутрішнього прогнозування таким чином, що набір найбільш ймовірних режимів внутрішнього прогнозування має розмір, який дорівнює заздалегідь визначеному числу, яке більше ніж або дорівнює двом. Відеокодер також сконфігурований, щоб кодувати значення, що представляє фактичний режим внутрішнього прогнозування для блока, на основі, щонайменше частково, набору найбільш ймовірних режимів внутрішнього прогнозування, і кодувати блок, використовуючи фактичний режим внутрішнього прогнозування. Відеокодер може бути далі сконфігурований, щоб кодувати блок, використовуючи фактичний режим внутрішнього прогнозування, наприклад, кодувати або декодувати блок. Відеокодери і відеодекодери можуть реалізувати ці способи.
