Abstract

The invention relates to a video projection device, comprising at least one terminal with the video data for projection, a server and a projector, said server, being connected to the projector by a hard-wire connection and accessible from a communication network, characterised in that the terminal may be connected, by means of the network and a network access processor, to a website hosted by the server, to download a file with an .ocx extension, comprising a remote control programme for the projection with an interface (ActiveX), the running of which by the network access processor permits the projection, by a video programme suitable for the projector, of the video data displayed on the screen of the terminal.

Claims

1. Video-projection device comprising at least one terminal including video data to be projected, a server and a projector, the server being connected to the projector by hardwire connection and being accessible via a communication network, terminal being connectable, via the network and network access software to a web site hosted by the server, to load an .ocx extension file including remote control projection software offering an interface whose execution by the network access software allows the projection, by use of video software adapted to the projector, of the video data displayed on the screen of terminal.

2. Video-projection device as in claim 1, wherein the terminal and the server each comprise a network card enabling them to connect to the communication network and to communicate together via the communication network.

3. Video-projection device as in claim 2, wherein the communication network includes a wireless network.

4. A method of video-projecting video data displayed on a screen of a terminal, the method comprising:

executing network access software on the terminal the terminal is connected to an Internet communication network,

entering a determined URL address into the network access software to access a web site hosted by a server via the Internet communication network,

downloading a web page from said web site in the network access software of the terminal, with which an .ocx extension file is linked, the software comprising remote control projection software offering an interface (ActiveX) enabling the network access software and the scripts of the web page to execute and control the .ocx extension file.

sending video data displayed on the screen of the terminal to the communication network by executing the .ocx extension file with the network access software,

receiving video data by video software adapted to the video-projector, which is installed on the server, and transmitting data to the video-projector.

5. Video-projection method as in claim 4, wherein the video data, before being sent to the servers, is compressed by the .ocx extension file then, before being sent to the video-projector, is decompressed by the video software.

6. Video-projection method as in claim 5, wherein the stopping of projection is prompted by closing the network access software on the terminal.

7. Video-projection method as in claim 5, wherein execution of the .ocx extension file is prompted by activating a button associated with the .ocx extension file execution function, and shown on the web page with which the .ocx extension file is linked.

8. Video-projection method as in claim 7, wherein stopping of the projection is prompted by activation of a button associated with the stop function of the .ocx extension file execution function and shown on the web page with which the .ocx extension file is linked.

9. Video-projection method as in claim 5, wherein the stopping of projection is prompted by closing the network access software on the terminal.

10. Video-projection method as in claim 5, wherein execution of the .ocx extension file is prompted by activation of a button associated with the .ocx extension file execution function, and shown on the web page with which the .ocx extension file is linked.

11. Video-projection method as in claim 4, wherein the stopping of projection is prompted by closing the network access software on the terminal.

12. Video-projection method as in claim 4, wherein execution of the .ocx extension file is prompted by activating a button associated with the .ocx extension file execution function, and shown on the web page with which the .ocx extension file is linked.

13. Video-projection method as in claim 12, wherein stopping of the projection is prompted by activation of a button associated with the stop function of the .ocx extension file execution function and shown on the web page with which the .ocx extension file is linked.
