Abstract:
1. A transmission apparatus comprising: a communication unit for performing transmission and reception of encoded data packets with other terminals; a redundant code generating unit for generating a redundant code associated with a data packet for restoring a loss of the data packet; a redundant code control unit for controlling a band used for the redundant code; a buffer for accumulating retransmission packets that can be retransmitted to the other terminals; a retrieval unit for retrieving a corresponding retransmission packet from the buffer for retransmission after receiving a retransmission request for the data packet from another terminal; a retransmission control unit for controlling a band used for retransmission; and a band control unit controlling to keep the sum of the band used for retransmission and the band currently used for the redundant code.
