摘要:
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.

A method for synchronizing of multimedia flows provided by different sources or transmitted via different transport protocols to a single receiving device or are designed to be rendered by different rendering devices. According to the invention, a reference datum representative of a datum of the first multimedia flow is provided in the second multimedia flow and associated with a datum of this second multimedia flow to synchronise the two flows. This reference datum constitutes a timing reference for the datum of the second multimedia flow with which it is associated. It is used to synchronize the two multimedia flows.

A method for delivering content to at least two terminals for synchronous playback is described. The method includes providing a first association of content to a preamble sequence, providing a second association of content to an ending sequence, providing estimations of data delivery duration from a server to at least two terminals and a playback duration of the preamble sequence in at least one of the first and second association, delivering the first and second association to the terminals wherein the playback duration of the preamble sequence is greater than or equal to the largest difference between the estimations, and wherein the estimations of data delivery duration allows each of the at least two terminals to evaluate a local temporization duration for playing-back synchronous content.

The invention enables the different access links between a local network and a remote network to be used in a common and transparent manner. The invention is based on the use of various IP tunnels using the different access links between an appliance on the local network of the user and an appliance on the remote network. Said tunnels are embodied as a single link providing access to the remote network.

The invention relates to a method for navigation in a panoramic video sequence displayed on a user terminal. The video sequence is divided into a plurality of non-overlapping video patches each corresponding to a zone of the video sequence. The video patches required to form a zone of the panoramic video sequence to be displayed on a screen of the user terminal, called the visibility zone, are determined according to navigation commands.According to the invention, the video patches are provided to the user terminal, for one part, via a first transmission network and, for another part, via a second transmission network distinct from said first transmission network.
