Abstract
Es descrito un método de actualización de parámetro que es utilizado para la codificación y decodificación de entropía de una conversión. Un elemento de sintaxis que indica un nivel de coeficiente de conversión es binarizado al utilizar un parámetro. El parámetro es actualizado o mantenido en función del resultado obtenido comparando el tamaño del coeficiente previo de conversión con un cierto umbral obtenido en función del parámetro previo utilizado para la binarización inversa del elemento de sintaxis de nivel de coeficiente de conversión previa. El cierto umbral es establecido para tener un valor proporcional al parámetro previo y si el parámetro previo es actualizado, el parámetro actualizado tiene un valor que se incrementa, en forma gradual, en comparación con el parámetro previo.
