ABSTRACT:
A data transmission apparatus having a storage device for storing at least one structure data piece of a data processing device in a receiving data processing apparatus, a computation device for computing a transmission error detection code from the structure data stored in the storage device and a device for attaching the transmission error detection code computed by the computation device to the structure data stored in the storage device. The data transmission apparatus further includes a transmitter for transmitting the structure data to which the transmission error detection code is attached to a receiving apparatus, a receiver for receiving a retransmission request for each structure data piece returned from the receiving apparatus when a transmission error is detected based on the transmission error detection code and structure data transmitted by the transmitter, and a device for responding to the restransmission request for each structure data piece received by the reception means by retransmitting the corresponding structure data piece to the receiving apparatus.
