Abstract

В одному прикладі пристрій включає в себе відеокодер, виконаний з можливістю визначення контексту для ентропійного кодування біна значення, що вказує останній значущий коефіцієнт блока відеоданих з використанням функції індексу згаданого біна, і кодування згаданого біна з використанням визначеного контексту. Відеокодер може кодувати або декодувати згаданий бін, використовуючи контекстно-адаптивне бінарне арифметичне кодування (САВАС). Згадана функція також може залежати від розміру блока. При такій конфігурації немає необхідності запам'ятовування пристроєм таблиці, що вказує контекстні індекси для згаданих контекстів.In one example, the device includes a video encoder configured to define the context for entropy encoding of the bin value, indicating the last significant factor of the block of video data using the index function of said bin, and encoding said bin using a defined context. The video encoder can encode or decode said bin using context-adaptive binary arithmetic encoding (SAVAS). The mentioned function may also depend on the size of the block. With this configuration, there is no need to memorize a table that specifies contextual indexes for the contexts mentioned.
