Abstract

EN UN SISTEMA DE RESPALDO DE RESPUESTA DE TELEVISION DONDE MUCHAS ESTACIONES RECEPTORAS SE COMUNICAN CON UNA ESTACION TRANSMISORA DE TELEVISION POR MEDIO DE PULSOS RF GENERADOS POR OSCILADORES RF EN LAS ESTACIONES RECEPTORAS, LOS REQUERIMIENTOS PARA MANTENER TODOS LOS OSCILADORES EN FRECUENCIA SE CONSIGUEN MEDIANTE EL CONTROL AUTOMATICO DE LA FRECUENCIA DEL OSCILADOR RF USANDO SEÑALES DE SINCRONIZACION PORTADAS EN LA SEÑAL DE VIDEO RECIBIDA DEL ESTUDIO DE TELEVISION. MEDIANTE ESTE INVENTO HA SIDO POSIBLE CONTROLAR LA FRECUENCIA DE UN OSCILADOR DE MEGAHERZIO MULTIPLE CON TANTA EXACTITUD COMO SE DESEE DESDE SEÑALES DE SINCRONIZACION DE RELATIVAMENTE BAJA FRECUENCIA TALES COMO LOS PULSOS DE SINCRONIZACION DE VIDEO HORIZONTAL Y VERTICAL. DE ESTA FORMA UN CONTADOR DE OSCILACIONE SE CONMUTA POR UN PERIODO DE TIEMPO MUY EXACTO MEDIANTE PULSOS DE SINCRONISMO, Y LA CUENTA DE OSCILACIONES SE COMPARA CON UN DATO QUE REPRESENTA LA FRECUENCIA DE OSCILACION DESEADA. PARA EVITAR QUE LAS ESTACIONES RECEPTORAS CONTESTEN CON PULSOS RF EN RESPUESTA A REQUERIMIENTOS CONTENIDOS EN GRABACIONES DE VIDEO DOMESTICO DE SEÑALES EMITIDAS PREVIAMENTE SE CODIFICA EL TIEMPO DE EMISION EN TODA PREGUNTA QUE CONTENGA TRANSMISIONES DE TELEVISION, Y COMPARANDO EN LAS ESTACIONES RECEPTORAS LA INFORMACION DEL TIEMPO DE EMISION DE LA SEÑAL RECIBIDA CON EL TIEMPO DEL RELOJ DE RESPALDO DE BATERIAS LOCAL CONTENIDO EN CADA ESTACION RECEPTORA ASI LA DESCRIMINACION DE GRABACIONES DE VIDEO ES POSIBLE COMPARANDO EL TIEMPO DE EMISION DE VIDEO RECIBIDO CON EL TIEMPO LOCAL.
