Abstract: Provided is a method for effectively suppressing packet losses by burst losses without an increase in delay by adaptively or fixedly changing a size of an FEC encoded block even when the number of packets per unit time is small. Each communication device 101 includes a transmitting unit 102 and a receiving unit 103. The transmitting unit 102 has a function of calculating forward error correction (FEC) codes based on the number of packets per encoding time and a value of a burst loss time of a network line. The receiving unit 103 decodes an FEC encoded packet and measures line quality information of the network for transmission to the transmitting unit 102. The transmitting unit 102 transmits the packets at equal intervals for as long as it is required for encoding, and can change a system for calculating FEC based on the burst loss time and the encoding time.
