ABSTRACT:
A receiving unit receives a group of packets transmitted from a transmitting apparatus. A detecting unit detects a missing packet based on the received group of packets. A first output unit outputs data corresponding to the group of packets, irrespective of a result of the detection by the detecting unit. A transmitting unit transmits a retransmission request for the missing packet to the transmitting apparatus. A re-receiving unit receives the missing packet retransmitted from the transmitting apparatus in response to the retransmission request. A second output unit outputs data corresponding to the group of packets and the retransmitted packet.
