Abstract

UN GRABADOR DE CINTAS DE VIDEO DIGITAL (3), QUE REPRODUCE DE UN MEDIO GRABADO UNA SEÑAL DE VIDEO DE ALTA DEFINICION DIGITAL QUE TIENE EN LA MISMA DATOS DE PREVENCION DE COPIA, EXTRAE LOS DATOS DE PREVENCION DE COPIA DE LA SEÑAL REPRODUCIDA (5), GENERA A PARTIR DE LOS DATOS DE PREVENCION DE COPIAS DIGITALES EXTRAIDOS UNA SEÑAL ANALOGICA DE INHIBICION DE COPIA QUE TIENE EL MISMO FORMATO DE DATOS QUE UNA SEÑAL DE INHIBICION DE COPIA SUPERPUESTA SOBRE UNA SEÑAL DE VIDEO DE DEFINICION ESTANDAR (6), CONVIERTE LA SEÑAL DE VIDEO DE ALTA DEFINICION DIGITAL REPRODUCIDA EN UNA SEÑAL ANALOGICA Y SUPERPONE LA SEÑAL DE INHIBICION DE COPIA ANALOGICA SOBRE LA SEÑAL ANALOGICA DE SALIDA (4). PARA GRABAR UNA SEÑAL DE VIDEO DE ALTA DEFINICION, EL GRABADOR DE CINTAS DE VIDEO DIGITAL (13) RECIBE UNA SEÑAL DE VIDEO DE ALTA DEFINICION ANALOGICA QUE TIENE SUPERPUESTA SOBRE LA MISMA UNA SEÑAL DE INHIBICION DE COPIA QUE TIENE EL MISMO FORMATO DE DATOS QUE LA SEÑAL DE INHIBICION DE COPIA SUPERPUESTA SOBRE UNA SEÑAL DEVIDEO DE DEFINICION ESTANDAR, EXTRAE LA DEFINICION DE COPIA DE LA SEÑAL DE VIDEO DE ALTA DEFINICION ANALOGICA RECIBIDA (16), SUMINISTRA LA SEÑAL DE VIDEO DE ALTA DEFINICION ANALOGICA RECIBIDA CUANDO ESTA SEÑAL NO ESTA PROTEGIDA CONTRA COPIAS, CONVIERTE LA SEÑAL DE VIDEO SUMINISTRADA EN UNA SEÑAL DIGITAL, GENERA DATOS DE PREVENCION DE COPIA DIGITALES A PARTIR DE LA SEÑAL DE INHIBICION DE COPIA EXTRAIDA (15), AÑADE LOS DATOS DE PREVENCION DE COPIA DIGITALES A LA SEÑAL DIGITAL, Y GRABA SOBRE UN MEDIO DE GRABACION LA SEÑAL DIGITAL CON LOS DATOS DE PREVENCION DE COPIA DIGITALES AÑADIDOS A LA MISMA.
