Abstract

Se proporcionan sistemas y métodos para decodificar marcas de agua en cuadros de video. Un dispositivo de medios puede recibir un cuadro de video que incluye una primera región predeterminada que comprende una marca de agua y una segunda región predeterminada que tiene valores de pixel seleccionados para reducir la perceptibilidad de la primera región predeterminada. El dispositivo de medios puede detectar la marca de agua en la primera región predeterminada del cuadro de video e identificar uno o más subconjuntos contiguos de pixeles que corresponden a un primer valor de pixel y uno o más subconjuntos contiguos de pixeles que corresponden a un segundo valor de pixel. El dispositivo de medios asigna entonces un primer símbolo al uno o más subconjuntos contiguos de pixeles que corresponden al primer valor de pixel y un segundo símbolo al uno o más subconjuntos contiguos de pixeles que corresponden al segundo valor de pixel. El dispositivo de medios genera entonces una primera secuencia de símbolos a partir de los símbolos asignados.
