Abstract
La legislacion actual requiere la posibilidad de encriptado cuando se almacenan programas de television recibidos mediante una emisora. Sin embargo, los aparatos de reproduccion legados no podrán reproducir tales datos encriptados de una manera regular, posiblemente lo efectuan de forma incorrecta esto puede resultar en problemas tales como el dano de los parlantes. Por lo tanto, la presente tiene el proposito de esconder cualquiera de tales flujos daninos mediante la provision intencional de tales flujos con una identificacion erronea durante el proceso de encriptado. Entre otras cosas la presente provee un método y circuito para encriptado y un método y circuito para desencriptado. La presente es especialmente adecuada para grabadoras de DVD, pero también puede emplearse para otros grabadores de audio/vídeo. Es más, la presente puede ser usada para encriptar datos que no son audiovisuales.
