Abstract

Las implementaciones se relacionan con varios aspectos para modificar o utilizar una corriente de bits codificada, o para recuperar la información de marca de agua de datos. En una implementación, la corriente de bits codificada se modifica para permitir la aplicación de una marca de agua en una corriente de bits codificada sin cambiar la codificación de cualquier otro elemento de sintaxis en la corriente de bits. Esto se lleva a cabo al identificar las condiciones necesarias para cambiar un elemento de sintaxis codificado sin interrumpir la interpretación de los elementos codificados posteriores. El elemento de sintaxis codificado se reemplaza con otro valor codificado cuando el valor modificado genera las mismas variables de decodificación que el valor original hubiera generado. Las implementaciones particulares se enfocan en elementos de sintaxis codificados con el uso de la codificación por entropía, incluyendo por ejemplo, la codificación aritmética binaria adaptable con base en contexto (CABAC). Sin considerar el tipo de codificación o marca de agua, varias implementaciones pueden proporcionar la recuperación de la información de marca de agua. Las implementaciones particulares recuperan la información de marca de agua con el uso de datos de detección y la información de características.
