87 ; equal to the estimated jitter multiplied by the scaling factor. The default value for the scaling factor
88 ; is about 1.4 (scaling=22), meaning that the target average playout delay is equal to the estimated
89 ; jitter. If less packets should be dropped because of jitter, the scaling factor has to be increased. An
