<p><P>PROBLEM TO BE SOLVED: To provide an improved data transmission system and its method capable of keeping real time characteristics in data reproduction, with no change in data transmission efficiency, even if transmission error of packets occurs. <P>SOLUTION: A data transmission device 210 comprises an interruption process means 266 which, if a prescribed second time or more is consumed for packet transmission, interrupts re-transmission of a packet and instructs a data reception device to interrupt re-transmission by a specified process. The data reception device 220 comprises a data process means 360 for processing data while a packet is missed according to the specified process in the data transmission device. With this configuration, real time property in data reproduction is maintained without changing data transmission efficiency, even if transmission error of packets occurs. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
