The present invention concerns a system and a method for synchronizing
interactive content with individual video stream. In particular, it
concerns a method for generating an interactive mark, comprising, at a
generating device, the steps of receiving video packets of a video
stream, creating an interactive mark intended to enable an interactive
service during a period of the video stream, periodically inserting the
interactive mark into Internet Protocol packets, noted IP-based packet,
said IP-based packets being synchronized with packets that transport the
associated video stream, and sending the IP-based packets.
