METHOD FOR CONFIGURING AN ADAPTIVE SOURCE ENCODER BASED ON A PREDICTION OF FUTURE TRANSMISSION CONDITIONS, AND TERMINAL AND SYSTEM IMPLEMENTING THE METHOD

摘要

The invention relates to a method for configuring a source encoder that is on-board a terminal and that transmits a data stream encoded by said encoder in a wireless telecommunications network using at least one radio link. The method includes at least: a step (100, 101) of acquiring measurements D_mes performed by the terminal, as well as predetermined data D_carte associated with geographical coordinates and contained in a reference map, said measurements D_mes and data D_carte being of the same type and representative of the quality of the radio link; a step (102) of estimating the current position of the terminal at a moment T_n; a step (103) of predicting the position of the terminal at a future moment T_n+1; a step (104) of determining a value D representative of the quality of the radio link obtained by combining D_mes and D_carte, the contribution of D_mes and D_carte to the value D being dependent on the speed of the terminal; a step (105) of determining a set of configuration parameters for the source encoder, said set being selected using a correspondence table matching a value of D to a set of configuration parameters; and a step of applying the set of configuration parameters to the source encoder such that the same are taken into account at the moment T_n+1.
