Abstract

Se provee un método para derivar un valor para un primer elemento de sintaxis, Syntax_A. El método comprende determinar si Syntax_A está presente en un flujo de bits. El método comprende, como resultado de determinar que Syntax_A no está presente en el flujo de bits, derivar el valor de Syntax_A para que sea igual a un primer valor, B, si se cumple una primera condición, o derivar el valor de Syntax_A para que sea igual a un segundo valor, C, si se cumple una segunda condición.
