The system incorporates two data bases (10,30), interacting with a data delivery circuit (20) with a data store and data processing circuits. Object data (211v1) is transmitted from the delivery circuit to the data bases at a time (t1). There is a blank period (t2) and further data (211v2) is transmitted at a third time (t3). There is a second blank period (t4). At a time (t51) actual object data (211) are sent, step (401). Further steps (405-420) involve return of the first two sets of data to the data delivery circuit at time (t52). At times (t53) and (t54), further data (211-3d,211v3) and (211-2d) are transmitted. |
