Abstract

У одному прикладі, розкритий пристрій для кодування коефіцієнтів, асоційованих з блоком відеоданих, під час процесу кодування відео, при цьому пристрій включає в себе відеокодер, виконаний з можливістю кодувати координати X і Y, які вказують позицію останнього ненульового коефіцієнта в блоці згідно з порядком сканування, асоційованим з блоком, коли порядок сканування містить перший порядок сканування, і кодувати переставлені координати X і Y, які вказують позицію останнього ненульового коефіцієнта в блоці згідно з порядком сканування, коли порядок сканування містить другий порядок сканування, при цьому другий порядок сканування відрізняється від першого порядку сканування.
