Abstract

В одному прикладі, аспекти даного розкриття стосуються способу кодування відеоданих, який включає в себе визначення контекстної інформації для блока відеоданих, де блок включений в кодовану одиницю відеоданих, де блок знаходиться нижче верхнього ряду блоків у кодованій одиниці, і де контекстна інформація не включає в себе інформацію із сусіднього зверху блока в кодованій одиниці. Цей спосіб також включає в себе ентропійне кодування даних блока за допомогою визначеної контекстної інформації.
