Abstract

UN SISTEMA DE REPRESENTACION DE SISTEMAS DE PRESENTACION EN VIDEO DE <<IMAGEN A IMAGEN>> DEPENDE DE LAS RELACIONES DE TEMPORIZACION CRITICAS ENTRE LAS SE ALES DE ENTRADA Y LAS SE ALES DE RELOJ USADAS PARA MUESTREAR Y PRESENTAR TANTO LAS SE ALES DE GRANDES IMAGENES COMO DE PEQUE AS IMAGENES. LAS SE ALES DE VIDEO DE VARIAS FUENTES, POR EJEMPLO LAS DE VTR (GRABADOR DE VIDEO EN CINTA), TIENDEN A PONER VIBRACIONES EN BASES DE TIEMPO, LO QUE PUEDE ORIGINAR QUE LA IMAGEN PEQUE A PUEDE SER REDUCIDA EFECTUANDO RETRASOS ADAPTATIVOS DE SE AL EN LA SE AL DE IMAGEN DE RELOJ DEL SISTEMA CON RESPECTO A LOS IMPULSOS DE SINCRONIZACION HORIZONTAL DE LA SE AL DE IMAGEN PEQUE A Y/O GRANDE.
