DATA SENDING/RECEIVING SYSTEM, DATA RECEIVING DEVICE, AND DATA RECEIVING METHOD BASED ON GENERATING A TEMPORARY FILE-NAME AND TEMPORARY FILE-SIZE ACCORDING TO A POSITION INFORMATION BEFORE STORING ON THE RECEIVING SIDE

摘要

A data sending/receiving system, data receiving device and data receiving method enable technique of efficient data; reception to be provided in such a way that even though when the system receives data whose file-name, file-size and so forth are unknown, the system determines temporary file-name and/or file-size with possible bounds, before implementing storing processing. A sending device converts file to be sent into packet data, and adds identification information of the file and position information of the packet data in relation to the file to respective packets. A receiving device generates a temporary file-name and a temporary file-size according to an identification information, before storing packet data associated with the temporary file-name in storage device.
