Abstract
Un método de decodificación de datos de vídeo comprende actualizar un valor estadístico de coeficiente con base en uno o más coeficientes de transformada de un bloque de transformada (TB), en donde la actualización del valor estadístico de coeficiente comprende, para cada coeficiente de transformada respectivo del uno o más coeficientes de transformada del TB: realizar un proceso de derivación para determinar un valor temporal, en donde el proceso de derivación se determina con base en al menos en parte en qué procedimiento de codificación de una pluralidad de procedimientos de codificación se usa para codificar el coeficiente de transformada respectivo, la pluralidad de procedimientos de codificación que incluye un procedimiento basado en contexto para codificar el coeficiente de transformada respectivo y codificar el coeficiente de transformada respectivo como un valor absoluto; y establecer el valor estadístico de coeficiente como un promedio del valor estadístico de coeficiente y el valor temporal; determinar un valor histórico con base en el valor estadístico de coeficiente; determinar un parámetro Rice para un coeficiente de transformada específico del TB.
