Abstract:
1. An FEC transmission processing apparatus comprising: a connecting unit configured to connect to a media packet generator that generates media packets; a media packet acquiring unit configured to successively acquire the media packets from the media packet generator; a media packet transmission unit configured to transmit the media packets acquired by the media packet acquiring unit to a media packet reception processing apparatus over a network, the media packet reception processing apparatus receiving and processing the media packets; an FEC packet generation unit configured to carry out FEC calculation processing using media packets acquired within a first period of a predetermined time length after a first media packet is acquired to thereby generate a plurality of FEC packets, the FEC packets being used for the media packet reception processing apparatus to recover a lost media packet and the first media packet being a media packet acquired first among the media packets subjected to the FEC calculation processing; and an FEC packet transmission unit configured to transmit the FEC packets to the media packet reception processing apparatus in a second period of the predetermined time length after the first time period passes.
