Abstract

UN SISTEMA PARA SOLAPAR SEÑALES DE CARACTER DIGITAL SOBRE UNA SEÑAL DE FUENTE DE VIDEO ANALOGICO QUE COMPRENDE UNA SUBPORTADORA COLOR PREDETERMINADA COMPRENDE UN BUCLE DE BLOQUEO DE FASE SUBPORTADORA (14), UN DISPOSITIVO GENERADOR DE CARACTER DIGITAL (28), UN CODIFICADOR DE VIDEO DIGITAL (18), Y UN DISPOSITIVO DE CONMUTACION (24). EL BUCLE DE BLOQUEO DE FASE SUBPORTADORA GENERA SEPARADAMENTE UNA SUBPORTADORA COLOR Y UNA SEÑAL DE RELOJ DE SISTEMA QUE SE BLOQUEA EN LA SUBPORTADORA COLOR DE LA SEÑAL DE FUENTE DE VIDEO ANALOGICA. EL DISPOSITIVO DE GENERACION DE CARACTER DIGITAL DETECTA LA TEMPORIZACION HORIZONTAL Y VERTICAL DE LA INFORMACION DE PIXEL EN LA SEÑAL FUENTE DE VIDEO ANALOGICA, Y GENERA SEÑALES DE CARACTER DIGITAL QUE HAN DE SOLAPARSE EN PIXELES PREDERMINADOS DE LA SEÑAL DE FUENTE DE VIDEO ANALOGICO. EL CODIFICADOR DE VIDEO DIGITAL RESPONDE A LAS SEÑALES DE RELOJ DE SISTEMA Y SUBPORTADORA COLOR PARA GENERAR UNA SUBPORTADORA COLOR SEPARADA QUE SE BLOQUEA EN LA SUBPORTADORA COLOR DE LASEÑAL FUENTE DE VIDEO ANALOGICO. EL CODIFICADOR DE VIDEO DIGITAL TAMBIEN CONVIERTE LAS SEÑALES DE CARACTER DIGITAL DEL MEDIO GENERADOR DE CARACTER DIGITAL EN SEÑALES DE SALIDA DE VIDEO ANALOGICO QUE COMPRENDE LA SUBPORTADORA COLOR GENERADA EN EL CODIFICADOR DE VIDEO DIGITAL. EL MEDIO DE CONMUTACION DIRIGE LA SEÑAL DE SALIDA DE VIDEO ANALOGICO DESDE EL CODIFICADOR DE VIDEO DIGITAL O LA SEÑAL DE SALIDA DE VIDEO ANALOGICO A UNA SALIDA DEL SISTEMA DURANTE LOS TIEMPOS DE PIXELS CUANDO UN CARACTER DIGITAL HA DE SER SOLAPADO O NO SOLAPADO, RESPECTIVAMENTE, SOBRE LA SEÑAL DE FUENTE DE VIDEO ANALOGICO.
