Abstract
A receiving terminal is provided that prevents a load on a network near a receiving terminal from increasing when a retransmission request is made to a plurality of other terminals, and enables the probability of being able to compensate for a lost packet by means of a retransmission packet to be increased. In a receiving terminal that transmits a retransmission request for compensating for a lost packet lost in a network, a measurement section measures a time period corresponding to a distance in the network between the receiving terminal and a plurality of receiving terminals, a calculation section calculates for each of the receiving terminals a float (spare time period) found by subtracting the current time and a time period measured by the measurement section from a playback time at which a retransmitted packet is played back, and a decision section decides retransmission request transmission timing and a retransmission request transmission destination for each of the receiving terminals based on the calculated floats.
