Abstract
Proteccion contra copiado de señales de programa emitidos por television que son recibidas y registradas en un formato que reserva áreas de registro para informacion accesoria relacionada con el formato y reserva otras áreas de registro para señales de imágenes digitales. Cuando se determina que las señales de entrada recibidas para su registro son señales de programa de television, una señal de limitacion de generacion insertada ahí se establece en un estado de proteccion contra copiado y se registra para inhibir el copiado.
