<p>The method involves measuring quality level of a wireless radio link (20) i.e. upstream link, and modulating bit rate of compressed video stream emitted by a drone (10) in a direction of reduction of bit rate when an estimator indicates degradation of quality of link between the drone and a remote control (26). Control messages (ATCMB) are repeatedly emitted at constant nominal intervals. The level is measured from measurement of variability of intervals separating successive frames actually received by the drone determined from variance of the intervals on a preset number of anterior frames.</p> |
