Abstract
There is provided a transmission rate control method. In this method, data is transmitted to a receiver at the most recent transmission rate R, and an RTCP packet including a reception rate Rof the data is received from the receiver. When a network is in a congestion state, or when the network is in a non-congestion state and the most recent reception achievement rate Ris higher than the reception rate R, a reception achievement rate Ris calculated as a long-term EWMA of the reception rate R. When the network is in the non-congestion state and the most recent reception achievement rate Ris lower than the reception rate R, or when a time-out of the RTCP packet occurs, the reception achievement rate Ris calculated as a short-term EWMA of the reception rate R. A transmission rate Ris set based on the reception achievement rate R.
