Abstract
Un método para decodificar datos de video comprende determinar, con base en un formato de color de una imagen de los datos de video, cual modelo de contexto de entre un primer modelo de contexto y un segundo modelo de contexto usar para determinar un incremento de contexto para un elemento de sintaxis que indica un prefijo de una coordenada x o y de un último coeficiente de transformación significativo de un componente de color de un bloque de la imagen; y decodificar un contenedor del elemento de sintaxis aplicando Codificación Aritmética Binaria Adaptativa de Contexto (CABAC) usando un contexto determinado con base en el incremento de contexto para el elemento de sintaxis.
