Abstract
A packet data is formed of a plurality of ATM cells. When cells of the packet data are lost, especially if the packet data is an image or picture signal including synchronous signals, it becomes difficult to reproduce the image or picture on a receiving terminal. A data length compensating device compensates the lost cell. In order to deal with the lost cells lying over between two packets, a data length compensating device includes a lost cell detecting circuit which detects a lost cell to be included in the data according to the sequence number of the plurality of cells, compensation control circuit which outputs compensation information including the number of lost cells to be compensated, and inserting circuit inserts dummy data corresponding to the lost cells to be compensated based on the compensation information.
