For controlling synchronization between a multimedia flow and a related social network thread, a device able to capture the multimedia flow and the social network thread selects (S1) a time interval, determines (S2) a list of multimedia keywords associated with the multimedia flow and determines (S3) a list of social keywords associated with the social network thread, each multimedia keyword and each social keyword being associated with a timestamp. The device produces (S4) a filtered list of filtered multimedia keywords by selecting distinctive multimedia keywords, each filtered multimedia keyword being associated with a set of similar social keywords, computes (S5) a set of delays for at least one filtered multimedia keyword, each delay corresponding to the time difference between the timestamp of the filtered multimedia keyword and the timestamp of a similar social keyword associated with the filtered multimedia keyword, and determines (S6) a drift for the time interval by means of at least one set of delays. |
