Abstract

Se describen un método y aparato de codificación de entropía para un codificador o decodificador de video utilizando Codificador Aritmético Binario Adaptivo con Base en Contexto basado en múltiples tablas (CABAC). En una modalidad, un contenedor actual de unos datos binarios de un símbolo de codificación actual se codifica o decodifica de acuerdo con una probabilidad de un valor binario del contenedor actual y la probabilidad del valor binario se actualiza de acuerdo con el valor binario del contenedor actual para un siguiente contenedor al usar modelos de probabilidad de múltiples parámetros. Cada modelo de probabilidad de múltiples parámetros se actualiza utilizando al menos una tabla de búsqueda con el conjunto individual del estado de probabilidad como un índice de tabla para acceder a los contenidos de al menos una tabla de búsqueda. En otra modalidad, la actualización del rango se calcula para un intervalo del rango con base en un valor medio del intervalo del rango.
