Abstract
В примере способ кодирования видеоданных может включать в себя выбор в качестве части процесса энтропийного кодирования, контекста для синтаксического элемента, связанного с текущим элементом кодирования (CU), на основе информации, относящейся к глубине CU у одного или более соседних CU относительно текущего CU. Синтаксический элемент может представлять, разбит ли текущий CU на под-CU. Способ может включить в себя энтропийное кодирование синтаксического элемента на основе выбранного контекста.
