Abstract

CODIFICAR DE VIDEO-DISCO CONTROLADO POR MIACROPROCESADOR. UNA SEÑAL DE VIDEO COMPUESTA PROCEDENTE DE LA FUENTE (30) SE COMBINA DE UNA FORMA LINEAL EN UN ADICIONADOR (36) CON UNA CORRIENTE DE DATOS DIGITALES PROCEDENTE DE UN GENERADOR DE DATOS DIGITALES (38). UN DISPOSITIVO DE SINCRONIZACION (32) ALIMENTA UNA SUBPORTADORA DE COLOR E IMPULSOS DE SINCRONIZACION, DE MODO QUE LOS BITIOS DE DATOS DEL GENERADOR (38) SEAN SINCRONICOS CON LA SUBPORTADORA DE COLOR, DE MODO QUE EL MENSAJE DIGITAL SE CODIFIQUE EN LA LINEA HORIZONTAL ADECUADA EN EL INTERVALO DE SUPRESION VERTICAL. LOS TIBIOS DE INFORMACION QUE REPRESENTAN EL NUMERO DE CAMPO DE VIDEO Y EL NUMERO DE BANDA SE GENERAN EN UN APARATO (34) Y SE CONTROLAN CON UN MICROPROCESADOR. UN DISPOSITIVO DE ELEBORACION ADICIONAL DE LA SEÑAL (40) PONE EN CONDICIONES LA SEÑAL DE VIDEO COMPUESTA PARA EL MEDIO DE GRABACION. LA SEÑAL COMPUESTA ES DEL TIPO DE SUBPORTADORA ENTERRADA Y SE GRABA CON TECNICAS DE MODULACION DE FM.
