摘要

PROBLEM TO BE SOLVED: To make an information processing system speedily adaptive to the change of a network state.

SOLUTION: A picture transmission device 11 transmits a packet to a picture reception device 12 and receives a confirmation response from the picture reception device 12. The picture transmission device 11 acquires RTT and a packet loss rate based on the received confirmation response. The picture transmission device controls a transmission rate by a rate control algorithm which preferentially corresponds to the change of the packet loss rate when fluctuation of RTT is small and controls the transmission rate by a rate control algorithm which preferentially corresponds to the change of RTT when the fluctuation of the packet loss rate is small. Thus, the packet can be transmitted at an ideal transmission rate corresponding to the change of RTT and two parameters of the packet loss rate. The invention can be applied to an electronic apparatus connected to the network.
