Abstract

Un codificador de video puede ser configurado para determinar un valor para un parámetro cero con base en el parámetro Rice, en donde el valor para el parámetro cero identifica un valor codificado que corresponde a un nivel de coeficiente de cero; recibir un primer valor codificado para un primer coeficiente del segundo conjunto de coeficientes; y con base en el valor para el parámetro cero y el primer valor codificado para el primer coeficiente, determinar un nivel para el primer coeficiente.
