Abstract
The present document describes a device and method for synchronizing a motion signal corresponding to a media content with a media signal for the media content, the motion signal being for controlling a motion feedback system. The method comprises: receiving a portion of the media signal; obtaining a fingerprint corresponding to the received portion of the media signal; from reference fingerprints associated with time positions of at least one reference media content, identifying a reference time position of the media content corresponding to the obtained fingerprint; obtaining the motion signal associated with the identified reference time position of the media content; and outputting the motion signal synchronized with the media signal using the identified reference time position of the media content for controlling the motion feedback system.
