Abstract
Un método para inhibir la grabacion de video aceptable desde una senal de video, en donde en la técnica conocida de rayas cromáticas para evitar lagrabacion de senales de video, una fase de más de la mitad y menos de la totalidad de ladurac ion de cada ráfaga de sincronizacion cromática presenteen cada línea de video activa se modifica de manera tal que cualquier grabacion de cinta de video subsiguiente de la senal de vide muestre variaciones en lafidelidad cromática que aparecencomo b andas o rayas no deseadas de error cromático
