ABSTRACT:
A data transmitter10transmits packets each with a sequence number and a priority added. A data receiver20detects any packet loss by referring to the sequence numbers added to the packets, and if detecting any packet of high priority as having been lost, requests for packet retransmission. Based on information about thus detected packet loss, the data receiver20generates and transmits an RR packet110indicating the packet reception state. The data transmitter10extracts from the RR packet110a packet loss ratio200, and therewith, changes manners of priority assignment. The manners are so changed that the packet of high priority is found with a lower ratio when the packet loss ratio200is high, and when the packet loss ratio200is low, found with a higher ratio.
