Abstract

Video verisi entropi-kodlama/entropi-kod çözme için bir usul ve cihaz sağlanmaktadır. Video verisi entropi-kodlama usulü, bir mevcut bloğun bir kalıntı bloğunun frekans alanına dönüştürülmesiyle oluşturulan frekans alanının katsayılarının farklı iki tabanlı hale getirme usulleri kullanılarak iki tabanlı hale getirilmesini ve iki tabanlı hale getirilmiş katsayılar üzerinde iki tabanlı aritmetik kodlama gerçekleştirilmesini içerir. Bu şekilde, katsayıların frekanslarının yüksek veya düşük olmasına göre katsayılar uyarlamalı bir şekilde iki tabanlı hale getirilir, böylece video verisi sıkıştırma verimi arttırılır.
