Synchronization between multimedia flows and social network threads

A device 1 for controlling synchronization between a multimedia flow and a related social network thread, the device being able to capture the multimedia flow and the social network thread and comprising:

• means for selecting a time interval,
• means for determining a list of multimedia keywords associated with a part of the multimedia flow corresponding to the time interval, each multimedia keyword being associated with a timestamp,
• means for determining a list of social keywords associated with a part of the social network thread corresponding to the time interval, each social keyword being associated with a timestamp,
• means for producing 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,
• means for computing 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,
• means for determining a drift for the time interval by means of at least one set of delays.

A computer program capable of being implemented within a device for controlling synchronization between a multimedia flow and a related social network thread, the device being able to capture the multimedia flow and the social network thread, said program comprising instructions which, when the program is loaded and executed within said device, carry out the following-steps:

• selecting a time interval,
• determining a list of multimedia keywords associated with a part of the multimedia flow corresponding to the time interval, each multimedia keyword being associated with a timestamp,
• determining a list of social keywords associated with a part of the social network thread corresponding to the time interval, each social keyword being associated with a timestamp,
• producing 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,
• computing 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,
• determining a drift for the time interval by means of at least one set of delays.
