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 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 time marking for synchronous terrestrial broadcasting in at least one single-frequency zone of at least one audiovisual stream via at least one connection in which the at least one audiovisual stream is multiplexed with at least one other audiovisual stream broadcast via the at least one connection, the method including: inserting packets including at least one item of information representing a common reference clock, detecting at least one packet including information representing the number of days elapsed since a predetermined date, calculating the number of loopbacks of a counter during a given period, updating the counter at each packet of the audiovisual stream transmitted, inserting at least one packet including the value of the updated counter in the audiovisual stream in order to form a modified audiovisual stream and transmitting the modified audiovisual stream.

摘要： A method for broadcasting an alert service in a system for broadcasting digital audiovisual programs in a single-frequency network, wherein the method includes steps of: obtaining frames containing the alert service and other services; associating a mark for each frame; identifying the identifiers of the packets of audio and video components of the alert service and of other services; identifying the identifiers of packets of audio and video components of other services; receiving a command to broadcast an alert message; storing video and audio packets of the alert service as from the first frame mark following the reception of the alert message broadcast command; and replacing, from the second frame mark following the reception of the alert message broadcast command, all the packets of the video and audio components of the services other than the alert service with the packets of the alert service.
