Abstract

EL INVENTO SE REFIERE PRINCIPALMENTE A UN DISPOSITIVO Y A UN PROCEDIMIENTO DE GENERACION DE SEÑALES DE CONTROL. EL DISPOSITIVO SEGUN EL PRESENTE INVENTO PERMITE ELABORAR A PARTIR DE UNA REFERENCIA TEMPORAL UNICA LAS SEÑALES DE CONTROL DE ESCRITURA (WE) Y DE LECTURA (RE) DE LA INFORMACION CONCERNIENTE A UNA LINEA VIDEO EN UN DISPOSITIVO DE MEMORIZACION (7,8). ASI, SE FRANQUEAN LAS VARIACIONES POSIBLES ENTRE LA SINCRONIACION DE DOS LINEAS SUCESIVAS ORIGINADAS ESPECIALMENTE POR LA TRANSMISION. EL DISPOSITIVO, SEGUN EL PRESENTE INVENTO, SE APLICA EN ESPECIAL EN LA ELABORACION DE SEÑALES DE ESCRITURA Y DE LECTURA DE UN DISPOSITIVO DE MEMORIZACION (7,8) DESTINADO A ALMACENAR UNA LINEA DE IMAGEN VIDEO A PARTIR DE UNA REFERENCIA TEMPORAL COMUN. EL INVENTO SE APLICA PRINCIPALMENTE EN LA REALIZACION DE DISPOSITIVOS DE ELIMINACION DE INTERFERENCIAS DE EMISIONES DE TELEVISION CON INTERFERENCIAS, EN ESPECIAL DE PAGO.
