Abstract
Un método ejemplar para decodificar por entropía datos de video incluye recuperar un valor de inicialización predefinido para un contexto de una pluralidad de contextos utilizados en un proceso de codificación entrópica adaptable al contexto para codificar por entropía un valor para un elemento de sintaxis para una unidad independientemente codificable de datos de video; determinar, con base en el valor de inicialización predefinido y en un dominio lineal, un estado de probabilidad inicial del contexto; y decodificar por entropía, desde una corriente de bits y con base en el estado de probabilidad inicial del contexto, un bin del valor para el elemento de sintaxis.
