Abstract

EN UN METODO Y APARATO PARA CONTROLAR LA OPERACION DE UN DECODIFICADOR DE SEÑAL EN UN SISTEMA DE RADIODIFUSION, SE GENERAN UNA SEÑAL DE EMISION Y UN INDICADOR MUSICAL ENCRIPTADO Y EL INDICADOR MUSICAL SE AÑADE A LA SEÑAL. LA SEÑAL JUNTO CON EL INDICADOR MUSICAL ES EMITIDA Y RECIBIDA EN EL DECODIFICADOR, DONDE EL INDICATIVO MUSICAL ES DESENCRIPTADO Y COMPARADO CON UN VALOR DE VERIFICACION. SI SE DA UNA COINCIDENCIA, SE PERMITE OTRA OPERACION DEL DECODIFICADOR. SI NO SE DA UNA COINCIDENCIA, NO SE PERMITE OTRA OPERACION DEL DECODIFICADOR.
