Abstract

EN UNA SEÑAL DE IMAGEN DENTRO DE IMAGEN (PIP) (5) DE UN RECEPTOR DE TELEVISION EN COLOR, LOS PULSOS DE LA RAFAGA DE SINCRONIZACION CROMATICA PARA EXTRAER LA SINCRONIZACION CROMATICA DE UNA SEÑAL DE VIDEO QUE SE CORRESPONDE CON LA IMAGEN PRINCIPAL SON GENERADOS EN RESPUESTA A LOS PULSOS DE SINCRONIZACION HORIZONTAL (DH) PRODUCIDOS POR LA SECCION DEFLECTORA (23) DEL RECEPTOR DE TELEVISION. LA RAFAGA DE SINCRONIZACION CROMATICA SE USA PARA DERIVAR UNA SEÑAL SUBPORTADORA DE COLOR PARA REMODULAR LOS COMPONENTES DE COLOR DE LA BANDA BASE QUE SE CORRESPONDEN CON LA INSERCION DE LA IMAGEN PEQUEÑA. LOS PULSOS DE SINCRONIZACION HORIZONTAL (DH) RELACIONADOS CON LA DEFLEXION SE ACOPLAN A LA SECCION PIP PARA POSICIONAR DE FORMA APROPIADA LA IMAGEN PEQUEÑA EN RELACION CON LA IMAGEN PRINCIPAL SIN TENER EN CUENTA LOS AJUSTES DE CENTRADO HORIZONTAL. PARA SITUAR APROPIADAMENTE LOS PULSOS DE LA RAFAGA DE SINCRONIZACION CROMATICA, SE GENERA UNA SEÑAL DE CONTROL DE RETARDO DE PULSO DE BARRIDO EN RESPUESTA A LARELACION ENTRE LAS POSICIONES DE LOS PULSOS DE SINCRONIZACION HORIZONTAL RELACIONADOS CON LA DEFLEXION (DH) Y LOS PULSOS DE SINCRONIZACION HORIZONTAL DE LA SEÑAL DE VIDEO (CS) QUE SE CORRESPONDEN CON LA IMAGEN PRINCIPAL. LA SEÑAL DE RETARDO DEL PULSO DE LA RAFAGA DE SINCRONIZACION CROMATICA SE GENERA DE FORMA VENTAJOSA MEDIANTE UN CONTROL DE TELEVISION BASADO EN UN MICROPROCESADOR QUE RECIBE TANTO LOS PULSOS DE DEFLEXION (DH) COMO LOS PULSOS DE SINCRONIZACION HORIZONTAL RELACIONADOS CON EL VIDEO (CS) PARA EL CONTROL SOBRE LA PANTALLA Y LA SINTONIZACION RESPECTIVAMENTE.
