- this diffusion can be realized in various ways.
- the method returns to a conventional digital content broadcast during a step 216.
- the invention makes it possible to broadcast a dynamically selected content according to the event and the target group by means of an exchange of information between the triggering entity responsible for associating a content with terminals for an event and the control platform as well as other network entities.
- the steps are indicated with the same reference numerals as in FIG. 2 and an index corresponding to the different embodiments. Some steps can however be done in a different order.
- the request can be issued before the detection so that the system is ready to broadcast when the event occurs.
- a multicast stream such as a television channel, is transmitted from source 102 to a set of TE user terminals 108.
- the event is a time such as 20:00 detected in step 202-1.
- the detection of this event is coupled to the correlation database 124 to verify that the conditions for the broadcast of personalized content are met and to identify the content to be broadcast and the terminals of the target group during the step 204-1.

- a broadcast management module of the platform 130 then issues a command 210-1 for broadcasting the identified content to the broadcast equipment 104 upstream of the terminals of the target group.
- the control causes the content to be broadcast by the source 120 using the address of the source 102.
- the PIM-SSM broadcast protocol causes the broadcast equipment 104 to receive the streams from the source 120 considered closer so that the initial flow to the terminals of the target group is replaced by the personalized flow in a step 214-1.
- the platform informs the other entities of the network of the progress of the broadcast of the personalized content and, at the end of this broadcast, the broadcast equipment 106 automatically switches to the source 102 and resumes the broadcast of the initial content during the broadcast. step 216-1.
- the triggering equipment realizes the association between the event, the content and the target group.
- the control platform 130 receives directly an identifier of the content to be broadcast, an identifier of the target group and broadcast parameters.
- the triggering event is a static event such as a time event, the transmission of information between the triggering equipment and the control platform allows for greater flexibility and adaptability than in static systems with Automatic substitution of content.
- steps 204 to 210 consist in preparing the diffusion and are carried out before the detection step 202.
- the event whose detection is monitored is a chain change on a TE108 user terminal. However, this event must also be associated with certain characteristics and in particular with a location geographically translated by the address of a particular distributor (DSLAM).
- the method begins with the identification 204-2 of the content to be broadcast and terminals of the target group according to the characteristics of the event (time slot, original string and target string). As before, this identification requires access to databases 122 and 124.
- This information is transmitted by request 206-2.
- this request is not transmitted directly to the control platform but to the broadcast source to be retransmitted to several terminals in multicast mode during a step 400.
- Each terminal then decides whether it is concerned or not by the query for example by analyzing the location parameters.
- the target group terminals then download the content to be broadcast. This download is made in known manner and includes one or more requests 402.
- the platform 130 identifies the content to be broadcast as well as the broadcast parameters and in particular the type of broadcast, the addresses of the speakers and other.
- Such downloading before the triggering event is performed improves the responsiveness of the system. This is particularly effective in situations where the content needs to be broadcast multiple times or if its download significantly reduces bandwidth during another activity.
- step 202-2 the event considered is detected by the terminal which then undertakes to broadcast, in step 214-2, the downloaded content.
- the broadcasting of digital content resumes from the source 102 in a conventional manner.
- the embodiment shown with reference to FIG. 5 is similar in its first part to the embodiment shown with reference to FIG. 4.
- the monitored event is the activation of a service of Video on demand VoD.
- the method begins with the identification 204-4 of a content, a target group and an event with a request 206-4 containing this information.
- a transmission in multicast mode 500 similar to step 400 described above makes it possible to forward this information to the terminals.
- the method then proceeds in a manner similar to the embodiment described in FIG. 4 up to step 210-3 of issuing a command.
- the method After receiving the command 210-3, the method includes activating the video-on-demand service at a step 504.
- the video on demand service read event is enabled and is detected in step 202-3.
- This event is further associated with a time slot so that, in the described embodiment, every 30 minutes, personalized content is broadcast on the TE terminal 108 in step 214-3.
- FIG. 6 Another embodiment is described with reference to FIG. 6.
- the detection takes place before the identification and the control of the broadcast.
- the method starts with an activation 600 of a VoD service followed by the detection 202-4 of the event corresponding to the read request of the VoD. This event results in a VoD request 602 sent to the control platform.
- the control platform requires from the equipment 126 information on the content to be broadcast. Accordingly, the method then comprises identifying 204-4 the content to be broadcast and terminals of the target group for the detected event. In the embodiment described, this identification requires several exchanges between the different entities to take into account parameters such as for example:
- This broadcast command further includes customizable parameters for advanced customization 212-4 during broadcast 214-4. As indicated above, this advanced customization results for example in the display in the broadcast content information available only on the terminal.
- the broadcast of the selected content in VoD is suspended during the broadcast of the customizable content 214-4.
- the method comprises a step 604 of Feedback to the platform to inform the various sources of the progress of the broadcast. This makes it possible to interrupt a conventional broadcast during the duration of the personalized broadcast.
- This feedback also helps to pilot the implementation of certain functions. For example, fast-forwarding or grouping content may be disabled during the delivery of custom content.
- the identification of the digital content to be broadcast is carried out directly by the control platform which integrates the functions of the triggering equipment.
