Patent ID: 8782481

Claim:
A receiving terminal apparatus that transmits a retransmission request for compensating for a lost packet lost in a network, the receiving terminal apparatus comprising: a measurement section that measures a time period corresponding to a distance in the network between the receiving terminal apparatus and a plurality of other receiving terminal apparatuses; a calculation section that calculates, for each of the receiving terminal apparatuses, a float, by subtracting a current time and a time period measured by the measurement section from a playback time at which a retransmitted packet is played back, the float being a spare time period; and a decision section that decides, as retransmission request transmission destinations, a predetermined number of other receiving terminal apparatuses from the plurality of other receiving terminal apparatuses based on the calculated float and further decides a retransmission request transmission timing for each of the decided retransmission request transmission destinations based on the calculated float, wherein the calculation section calculates a plurality of the floats, each of which corresponds to one of the receiving terminal apparatuses, and the decision section decides the retransmission request transmission timing and the retransmission request transmission destinations in accordance with an order of the plurality of the calculated floats, and at least one of the measure section, the calculation section, and the decision section comprise a processor.
