摘要： PROBLEM TO BE SOLVED: To recover an error in data transfer from an information processor to a display device without leaving over the error as display in the display device. SOLUTION: A host device 100 transmits error checking information for checking an error to a display device 300 by adding it to packet data. The display control part 8 of the display device 300 receives the packet data and detects an error by using the error checking information. Moreover, when an error is detected, the display control part 8 outputs the request of the retransmission of the packet data to the host device 100. Then, the device 100 receives the request of the retransmission and retransmits the packet data in which the error is generated to the display control part 8.
