A system and method for transmitting a data stream between a server and a user terminal, comprises at least one satellite gateway associated with a satellite router communicating with at least one satellite terminal associated with a terminal router, wherein the terminal router is configured, when it receives a stream request from a user terminal, to search for it in its memory resources and, if appropriate, transmit it to the user terminal, the satellite router is configured to transmit the request to the server, estimate a popularity of the stream and transmit a message of correspondence between the stream and broadcasting parameters then convert the stream into a point-to-multipoint stream adapted to the broadcasting parameters, the terminal router is configured to convert point-to-multipoint streams into point-to-point streams and transmit them to the user terminals.
A system for transmitting a data stream between a server and one or more user terminals, comprising:
A method for transmitting a data stream between a server and one or more user terminals in a transmission system comprising at least one satellite gateway connected to said server through a satellite router, and configured to communicate with at least one satellite terminal via a satellite link, said system further comprising one or more terminal routers comprising memory storage resources, each user terminal being connected to said satellite terminal through one of said terminal routers, the user terminals being configured to make requests for data streams to said server, the method comprising the steps of:

This application claims priority to foreign French patent application No. FR 1500230, filed on Feb. 6, 2015, the disclosure of which is incorporated by reference in its entirety.
The invention lies in the field of high bit rate satellite communication systems, and more particularly the optimization of the use of the bandwidth in these systems.
Internet traffic, pulled primarily by the consumption of multimedia content of increasing volumes, and by the increase in the number of services, is increasing exponentially. This has a direct impact on the average bandwidth per user. However, the satellite communication links are provided with limited IP traffic transport capacities, which cannot increase during the life of the satellite.
The invention will be better understood and the features and advantages will become more apparent on reading the following description, given in a nonlimiting manner, and through the attached figures in which:
FIG. 1 presents an embodiment of an architecture of a satellite communication system according to the invention,
FIG. 2 presents a sequencing diagram of the steps of the satellite communication method according to the invention,
Internet traffic, pulled primarily by the consumption of multimedia contents, is experiencing exponential growth.
The average consumption of multimedia contents is increasing, with a current average of more than 6 hours per day per individual in the United States.
This growth is linked to:
