Abstract
Винахід описує методики обчислення значень для субцілих пікселів, що застосовуються кодером і декодером, щоб кодувати блоки відеоданих. В одному прикладі відеокодер виконаний з можливістю приймати значення для положень повного цілого пікселя з контрольної вибірки, застосовувати інтерполяційний фільтр відносно першої групи значень для положень повного цілого пікселя, щоб обчислити значення для першого субцілого пікселя одного з положень повного цілого пікселя, застосовувати інтерполяційний фільтр відносно другої, іншої, групи значень для положень повного цілого пікселя, щоб обчислити значення для другого, іншого, субцілого пікселя одного з положень повного цілого пікселя, кодувати поточний блок пікселів з використанням вектора руху, який вказує на один з першого субцілого пікселя і другого субцілого пікселя.
