Abstract

Una unidad de codificación de longitud variable 13 codifica en longitud variable un índice que indica un método de clasificación para llevar a cabo una clasificación de clase en cada bloque de codificación que tiene un tamaño mayor, el método de clasificación se determina por una unidad de filtro de bucle 11, y también codifica en longitud variable un parámetro acerca de un valor de desplazamiento para cada clase determinado para cada bloque de codificación que tiene el tamaño mayor con base en un proceso de binarización que utiliza un código unario truncado.
