摘要： A method for generating a stream from first and second data streams received, the data streams comprising frames, each frame containing a synchronization packet, a signaling packet giving information on the structure of the data stream and packets referred to as baseband frames. The method comprises the steps of aligning the two data streams received by putting in phase the synchronization packets or the signaling packets of the frames of each data stream, identifying, in one of the data streams received, baseband packets identifying packets of a first type, and inserting, in each frame of the first stream received, baseband packets of the frame of the second stream the synchronization packet of which is aligned with the synchronization packet of the frame of the first stream.

摘要： A method for generating an original total stream intended for being distributed to at least one broadcasting site, which includes a modulator and a transmitter sending a radiofrequency signal on a first frequency. The method implements the following acts: obtaining at least one transport stream comprising at least one transport packet; obtaining, from at least one modulation parameter for the broadcasting site, at least one starting instant of a modulation frame intended for being sent by the broadcasting site; inserting at least one modulation information packet in the at least one transport stream, at a position determined from the at least one starting instant; and generating the original total stream, including at least one physical layer pipe encapsulating the at least one transport stream carrying the at least one modulation information packet.

摘要： A method for synchronizing data, via a broadcast network, which includes at least one fixed transmitter and a plurality of broadcast sites. The synchronization method uses the following acts, at at least one of the broadcast sites: obtaining a delay, referred to as an absolute delay, determined from the geographic location of the broadcast site; determining an additional delay, by subtracting the absolute delay from a fixed delay shared by the broadcast sites in the network; resetting at least one time datum or at least one portion of a data stream from the fixed transmitter, applying the additional delay to the time datum or to the portion of the data stream.

摘要： A method for signalling, to a terminal, substitution of an item of content, broadcast via a broadcast network to which the terminal is connected, with a substitute item of content. Such a method includes: obtaining a substitute information packet including time information indicating a time of execution, by the terminal, of an action for substituting the broadcast item of content with the substitute item of content, wherein the time information corresponds to a date of rendering of an image of the broadcast item of content with reference to a reference clock embedded in the broadcast item of content; generating an event notification message including the time information; and inserting the event notification message into a data flow conveying the item of content broadcast within the broadcast network.
