Abstract

A method for a push server to broadcast data to terminals via an interface device, the data sent by the server passing through a distribution system enabling the data to be broadcast from the server to the device. The server transmits a stream of content data and web application data to the system; the system multicasts the stream of content data and web application data to the device; a receptor in the interface device receives the data; the data are stored in a storage device of the interface device; a local wireless connection is established between a terminal provided with a web browser and the interface device; a HTTP query is transmitted from the terminal to a web server of the interface device, the query requesting the execution of an application stored in the storage device; and the requested application is executed in the browser of the terminal.

Claims

1. A method for a push server to broadcast data to user terminals via an interface device, said data sent by the push server passing through a distribution system enabling the data to be broadcast from said push server to said interface device, said interface device comprising:

a receptor configured to receive data multicast by said distribution system in push mode;

a storage device configured to store said data;

a web server;

a connector configured to establish a local wireless connection with user terminals;

said method comprising;

transmitting by the push server of a stream of content data and web application data to the distribution system;

multicasting by the distribution system a stream of content data and web application data to said interface device;

receiving said data by the receptor;

storing said data in said storage device;

establishing a wireless local connection of a terminal with a web browser to said interface device;

transmitting an HTTP query from said terminal to said web server, said query requesting the execution of an application stored in said storage device; and

executing the requested application in the web browser of said terminal.

2. The method according to claim 1, wherein the connection between the interface device and the push server is a bidirectional connection.

3. The method according to claim 1, wherein said distribution system is a telecommunications satellite.

4. The method according to claim 3, wherein the connection between the push server and the interface device is a radiofrequency link between a principal ground station to which the push server is connected and the interface device via a telecommunications satellite.

5. The method according to claim 4, wherein the satellite is utilized bidirectionally such that the transmission of data from the push server to the interface device is carried out by utilizing the forward link of the satellite relaying the data transmitted by the principal ground station to the interface device and the transmission of data from the interface device to said push server is carried out by utilizing the return link of the satellite relaying the data transmitted by the interface device to the principal ground station.

6. The method according to claim 1, wherein said data are of two types:

content data integrated into multimedia files;

web applications intended to be executed locally on the user terminal.

7. The method according to claim 1, wherein the multicast broadcasting by the distribution system of the stream of content data and web applications data is done to a plurality of interface devices, each interface device ensuring the distribution of these data to user terminals connected to this interface device via its local wireless connection.

8. An interface device for implementing the method according to claim 1, the device comprising:

a receptor configured to receive data multicast by said distribution system in push mode;

a storage device configured to receive said data;

a web server;

a connector configured to establish a local wireless connection with user terminals.

9. The device according to claim 8, wherein the device comprises a transmitter configured to transmit data to said push server.

10. The device according to claim 8, wherein the device comprises a router configured to route the data received to a user terminal connected to said interface device via said wireless connector.

11. The device according to claim 8, wherein the device comprises a satellite antenna.

12. The device according to claim 8, wherein the connector includes a WiFi, WiMax or BlueTooth connector.

13. An automobile integrating an interface device according to claim 8.
