Abstract

Para codificar con CABAC, un valor de elemento de sintaxis no binario es mapeado a una secuencia binaria (cadena de bin), a través de un proceso de binarización. Un motor de codificación aritmética binaria codifica o decodifica un bin, en un modo regular (basado en contexto) y un modo de derivación.
