Abstract
A method for synchronising a first audio stream, reproduced in the form of a sound signal by a reproduction device near a terminal, with an alternative audio stream received by the terminal. The terminal also receives a control stream representing the first audio stream reproduced on the reproduction device, the control stream and the alternative audio stream being synchronised according to a single time reference. the method includes: capturing a portion of the sound signal; transmitting to the reproduction device a command to suspend the reading of the first stream; obtaining a first data item representing at least one portion of the captured sound signal; detecting the first data item in the control stream and, when the first data item is detected in the control stream, transmitting to the reproduction device a command to resume reading the first stream; and reproducing the alternative audio stream received by the terminal.
