Data reception system with determination whether total amount of data stored in first storage area exceeds threshold

摘要

A data reception system includes a data acquisition unit acquiring data from a predetermined transmission path, an access control unit storing the data acquired by the data acquisition unit in a predetermined storage area, and a plurality of storage areas. The plurality of storage areas includes a first storage area and a second storage area having a greater storable capacity and a lower storing speed compared to the first storage area. The access control unit further includes a transfer unit. The access control unit determines whether the total amount of data stored in the first storage area is in the excess of a predetermined threshold or not and causes a transfer unit to transfer the data acquired by the data acquisition unit to the second storage area to store the data in the second storage area when the total amount is in the excess of the threshold.
