Abstract

CIRCUITOS PARA LA REPRODUCCION DE INFORMACION EN FORMA DE CODIFICACION DIGITAL, COMO SEÑAL DE TEXTO DE VIDEO EN UNO O VARIOS CANALES DE TELEVISION, POR MEDIO DE CABLES O TRANSMISION SIN HILOS. LA INSTALACION PARA LA SELECCION DE PROGRAMAS Y LA PARTE DE ALTA FRECUENCIA DELA APARATO TELEVISOR SON USADOS PARA LA SELECCION Y DEMODULACION DE LA SEÑAL DE TELEVISION, MIENTRAS QUE UN DEMODULADOR DE TEXTO DE VIDEO SINCRONIZA Y REGENERA LAS SEÑALES DIGITALES RECIBIDAS. UN CIRCUITO PARA EL ANALISIS DE DIRECCIONES COMPRUEBA UNA SUCESION DE BITS A TRANSMITIR, MEMORIZADOS PREVIAMENTE EN UN REGISTRO PREVIO DE DIRECCIONES, Y EN CASO DE UN RESULTADO POSITIVO DE ESTA COMPROBACION LOS DATOS SON ALMACENADOS EN UNA MEMORIA, PARA SU POSTERIOR PROCESAMIENTO A UN DECODIFICADOR DE TEXTO DE PANTALLA.
