Abstract

EL SISTEMA SEGUN EL INVENTO ESTA DESTINADO PRA LA INVESTIGACION Y BUSCA DE VOCABLOS DE SINCRONIZACION DE UNA SEÑAL EN PARTE NUMERICA DEL TIPO D2MAC DE TELEVISION. ESTA PREVISTO PARA PONER EN MARCHA TRES MODOS DE FUNCIONAMIENTO SUCESIVAMENTE. EN UN PRIMER MODO LOS VALORES NECESARIOS PARA REGULAR LA GANANCIA Y EL NIVEL DE CORRIENTE CONTINUA DE LA SEÑAL DE TELEVISION SE OBTIENEN POR MEDIO DE UN DETECTYOR DE CRESTAS (18). EN UN SEGUNDO MODO ES IGUAL PERO EL DETECTOR ES VALIDO SOLAMENTE EN LOS PERIODOS DE SEÑAL NUMERICA DE SEÑAL D2MAC. EN EL TERCER MODO, LOS VALORES DE REGLAJE SE OBTIENEN MEDIANTE DISPOSITIVOS (13,8) QUE SE APOYAN EN LA MEDIDA DE PALIERS DE CADA LINEA Y DE LA LINEA 624. LA SEÑAL DE TELEVISION SE CONVIERTE EN SEÑAL NUMERICA POR UN CONVERTIDOR ANALOGICO/NUMERICO (6) QUE ALIMENTA NOTABLEMENTE EL DISPOSITIVO (8) NUMERICO DE MEDIDA DE LOS PALIERS DE IMAGEN, LOS RESULTADOS DE MEDIDA DEL DETECTOR DE CRESTAS (18) SON IGULAMENTE CONVERTIDOS EN VALORES NUMERICOS (17). LA GESTION DEL PROCESO Y EL TRATAMIENTO DE AL MENOS UNA PARTE DE LAS SEÑALES DE REGLAJE SON REALIZADOS POR UN MICRO-PROCESADOR (33) Y VARIAS SEÑALES DE REGLAJE SON DE NUEVO CONVERTIDAS EN VALOR ANALOGICO POR UN CONVERTIDOR NUMERICO ANALOGICO (10).
