Abstract

Se relaciona con un método y dispositivo para agregar o extraer una senal de informacion secundaria hacia/desde una secuencia de codigo de longitud de ejecucion limitada. Una polaridad de una longitud de ejecucion en una primera posicion predeterminada de una secuencia de codigo de longitud de ejecucion limitada es detectada y un parámetro reflejando el grado de libertad que se encuentra presente en el codigo de canal de longitud de ejecucion limitada, por ejemplo la seleccion de un patron de bit de union en el estándar CD, es fijado sobre la base de la polaridad detectada para así obtener una polaridad predeterminada de una longitud de ejecucion en una subsiguiente segunda posicion predeterminada de la secuencia de codigo de longitud de ejecucion limitada. La polaridad predeterminada entonces corresponde a un valor binario de la informacion secundaria. Así se provee un canal lateral de poca capacidad, el cual es posicionado muy cerca del canal físico tal que la informacion secundaria es difícil de detectar desde el flujo de bit EFM. Por lo tanto, el canal lateral puede ser usado como un canal escondido con propositos de proteccion de copia. La invencion también se relaciona con un portador de grabacion y una senal binaria comprendiendo la informacion secundaria.
