摘要

A congestion/non-congestion determining unit determines whether or not a communications network is in a congestion state. An FEC (forward error correction) packet generator generates error correction packets containing error correction data for correcting error of streaming data contained in transmission packets. When the determination result changes from a non-congestion state to a congestion state, an FEC transmission controller controls the error-correction-packet generation so as to change the number of error correction packets. The present invention is applicable to a remote TV conference system.
