Abstract
Se proporciona un método y aparato de codificación y un método y aparato de descodificación para seleccionar de manera adaptable un modelo de contexto usado para codificar por entropía y descodificar por entropía un elemento de sintaxis, con base en diversas formas de las unidades de codificación. El método de descodificación de representación visual incluye: determinar un modelo de contexto con base en información de forma de bloque que incluye por lo menos uno de una forma, dirección, anchura, relación de anchura y altura o tamaño de una unidad de codificación; obtener, a partir de una corriente de bits con base en el modelo de contexto, información acerca de un modo de forma de división para dividir la unidad de codificación; y determinar un modo de forma de división de la unidad de codificación, con base en la información acerca del modo de forma de división.
