Transmitting device, transmitting method, integrated circuit, and program

A transmitting device that transmits a communication packet to a receiving device via a communication channel, the transmitting device comprising:

• a transmitting unit configured to transmit the communication packet to the receiving device;
• a receiving unit configured to receive, from the receiving device, a feedback packet that is a response signal corresponding to the communication packet;
• a detecting unit configured to detect a change of a reception interval of the feedback packet;
• and
• a transmission rate determining unit configured to decrease a transmission rate at which the transmitting unit transmits the communication packet in the case where the change of the reception interval is detected, and to increase the transmission rate on the basis of an amount of change of a travelling speed of at least either the transmitting device or the receiving device before and after the decrease in the transmission rate.

A transmitting method for transmitting a communication packet to a receiving device via a communication channel, the method comprising:

• transmitting the communication packet to the receiving device;
• receiving a feedback packet, which is a response signal corresponding to the communication packet, from the receiving device;
• detecting a change of a reception interval of the feedback packet;
• and
• decreasing a transmission rate at which the communication packet is transmitted in the transmitting in the case where the change of the reception interval is detected, and increasing the transmission rate on the basis of an amount of change of a packet loss rate representing a loss rate of the communication packet and a jitter that is an amount of change of a transmission time of the communication packet, before and after the decrease in the transmission rate.

An integrated circuit that transmits a communication packet to a receiving device via a communication channel, the integrated circuit comprising:
