Abstract
LA INVENCION DESCRIBE UN SISTEMA DE GRABADO Y/O DE COPIADO PARA DATOS QUE HAN DE SER ALMACENADOS. LA NORMA PARA CINTA AUDIO DIGITAL (DAT) ESPECIFICA UNA IDENTIFICACION DE LA FUENTE QUE SE EMPLEA PARA CONTROLAR TODAS LAS OPERACIONES DE GRABACION Y/O COPIADO MEDIANTE UNA INTERFASE DIGITAL. DE ACUERDO CON LA INVENCION SE EMPLEAN SEÑALES ADICIONALES QUE, POR EJEMPLO, SE GRABAN SOBRE LA CINTA COMO INFORMACION ADICIONAL DIGITAL, LOS LLAMADOS SUBCODIGOS, EN ADICION A LAS SEÑALES DE IMAGEN Y DE AUDIO. LA FUENTE ORIGINAL DE LA GRABACION DE LA CINTA O DE LA CASSETTE DE VIDEO SE PUEDE IDENTIFICAR POR MEDIO DE LA SEÑAL ADICIONAL. ESTA INFORMACION PUEDE SER USADA PARA CONTROLAR TODAS LAS GRABACIONES POSTERIORES DE VIDEO, PARA ASEGURAR QUE LAS RESTRICCIONES DE COPIA, TALES COMO DERECHO DE COPIA, SON OBSERVADAS Y PARA IMPEDIR OPERACIONES DE COPIA NO AUTORIZADAS. PARA APARATOS DE GRABACION Y DE COPIA DE DATOS.
