Abstract
UN MODULO DESCODIFICADOR BASADO EN UN MICROPROCESADOR DE SEÑALES DE VIDEO DE TELEVISION QUE HAN SIDO CODIFICADAS SUPRIMIENDO PULSOS DE SINCRONIZACION Y/O INVIRTIENDO EL VIDEO DE IMAGENES. EL MODULO DESCODIFICADOR GENERA PUERTAS DE RESTABLECIMIENTO DEL SINCRONISMO Y/O PUERTAS DE INVERSION DE VIDEO DESARROLLADAS POR SEÑALES DE TEMPORIZACION PRESENTES EN EL BVI DE LA SEÑAL DE VIDEO CODIFICADA. LAS SEÑALES DE TEMPORIZACION BVI PUEDEN SER IMPULSOS DE SINCRONIZACION QUE NO SON SUPRIMIDOS DURANTE EL BVI O SEÑALES ESPECIALES DE TEMPORIZACION INTRODUCIDAS EN EL CODIFICADOR DE VIDEO. EL MICROPROCESADOR EN EL MODULO DESCODIFICADOR PUEDE CONTENER SEGMENTOS DE PROGRAMA SELECCIONABLES EXTERNAMENTE DONDE CADA SEGMENTO PERMITIRA LA DESCODIFICACION DE UNA VARIEDAD DIFERENTE DE CODIFICACIONES DE VIDEO.
