Abstract

Обчислювальний пристрій визначає, чи обмежений блок прогнозування (PU) у В-слайсі однонаправленим інтерпрогнозуванням. Додатково, обчислювальний пристрій формує список кандидатів на злиття для згаданого PU і визначає вибраного кандидата на злиття в списку кандидатів на злиття. Обчислювальний пристрій формує прогнозований відеоблок для згаданого PU на основі не більше одного опорного блока, зв'язаного з інформацією про рух, заданою вибраним кандидатом на злиття, якщо згаданий PU обмежений однонаправленим інтерпрогнозуванням. Обчислювальний пристрій формує прогнозований відеоблок для згаданого PU на основі одного або більше опорних блоків, зв'язаних з інформацією про рух, заданою вибраним кандидатом на злиття, якщо згаданий PU не обмежений однонаправленим інтерпрогнозуванням.
