Definitions
- the present invention relates to a method and a device for video projection, in particular wireless.
- Wireless video projection devices such as that shown in FIG. 2 are known in the prior art.
- This type of device comprises a terminal (1), a server (2) and a projector (3).
- a software (16) for remote control of the projection, making it possible to control the starting and stopping of the projection, must first be installed on the terminal (1).
- Video software (23), such as for example VNC viewer, is installed on the server (2), which is connected by wire link (5) to the projector (3).
- the execution of the software (16) for remote control of the projection by the operating system (12) of the terminal (1) causes the transfer of the video data (11) displayed on the screen (14) of the terminal (1 ), through a network card (10), from the terminal (1) to the server (2), via a wireless network (4).
- the server (2) receives this data by a network card (20), which transmits it to the video software (23).
- the video software (23) then broadcasts them to the projector (3), which allows the projection of the video data on a screen.
- a wireless video projection device consisting of at least one mobile terminal, such as an electronic organizer, and a projector.
- the terminal and the projector each include a network module for wireless communication with each other.
- Projection remote control software is installed on the terminal, for example by being downloaded from the projector.
- the data to be projected is transmitted to the projector from the terminal or from a data server connected to the projector by a wired link.
- This device also allows the management of the projection of data transmitted by several terminals on each of which is installed beforehand a remote projection control software, allowing simultaneous or in a certain order wireless projection of the data sent by the various terminals.
- a disadvantage of these devices known in the prior art is that it is necessary to start by installing the remote projection control software on the terminal before being able to use the terminal with this projector. Similarly, if several people wish to use the projector simultaneously, they must all install the said software on their terminals before using the projector, which is restrictive and takes time.
- Document EP 1 244 303 teaches a wireless video projection device making it possible to project, via a video projector, audio and video data transmitted by wireless connection from a terminal, such as a computer.
- a video projection device comprising at least one terminal containing video data to be projected, a server and a projector, the server being, on the one hand, connected to the projector by wire connection and, on the other hand , accessible by a communication network, characterized in that the terminal is connectable, via the network and network access software, to a website hosted by the server, to load by accessing this site web an .ocx extension file, including a remote projection control software offering an interface, whose execution by the network access software allows the projection, by video software adapted to the projector, of the displayed video data on the terminal screen.
- the terminal and the server each comprise a network card allowing them to connect to the communication network and to communicate with each other via this network.
- the network is a wireless network.
- Another object of the invention is to propose a method of video projection of video data displayed on the screen of a terminal. This object is achieved by a method, characterized in that it comprises at least the following steps: - execution of network access software on the terminal to allow connection of the terminal to an Internet communication network, - entry of '' a URL address determined on the network access software to access a website hosted by a server via this communication network, - downloading of a web page from said website into the network access software of the terminal, to which is linked a file with .ocx extension including a remote control software of the projection offering a interface, allowing network access software and web page scripts to execute and control the .ocx extension file, - sending video data displayed on the terminal screen by executing the file .ocx extension by the network access software to the communication network, - reception of the video data by video software, adapted to the video projector, which is installed on the server, and transmission of the data to the video projector.
- the video data, before being sent to the server, is compressed by the extension file .ocx, then, before being sent to the video projector, is decompressed by the video software.
- the stopping of the projection is caused by the closing of the network access software on the terminal.
- the execution of the .ocx extension file is caused by the activation of a button, associated with the execution function of the .ocx extension file, and represented on the web page to which is linked the .ocx extension file.
- the stopping of the projection is caused by the activation of a button, associated with the stop function of the execution function of the .ocx file, and represented on the web page at which is linked with the .ocx file.
- the terminal (1) comprises at least one terminal (1), a server (2) and a projector (3), the server (2) and the projector (3) being connected by a communication means (5) such as, for example, a wired connection.
- the terminal (1) is preferably, but not limited to, a portable computer.
- the terminal (1) and the server (2) each comprise a network card (respectively 10 and 20) allowing them to connect to a communication network and to communicate with each other via this network.
- This network is preferably a wireless network (4), such as Wi-fi, Bluetooth, GSM, etc.
- the invention consists, in a device and a method, to be projected by the video projector (3) onto the screen (not shown) of a conference room the video data (11) displayed on the screen (14) of the terminal (1) by the operating system (12) of the terminal (1) via the video card (13) of the terminal (1) on the screen of the projection room, without having to install software (16) for remote control of the projection on the terminal (1) as in the prior art (figure 2), which turns out to be a long and tedious operation, requiring the possession of a number of software (16) equal to the number of terminals on which it is necessary to install them.
- network access software (15), for example, but not limited to, Internet Explorer, is previously installed on the terminal (1). This step is generally carried out during the purchase of the terminal.
- the server (2) connected to the video projector, comprises an HTTP server (Hyper Text Transfer Protocol) which hosts a website (22) corresponding to a determined URL address.
- This website (22) comprises at least one web page to which is linked to at least one file with the .ocx extension, which includes the software (221) for remote control of the projection offering an ActiveX interface (222), allowing network access software (15) and web page scripts to run and control the .ocx file.
- HTTP server Hyper Text Transfer Protocol
- This website (22) comprises at least one web page to which is linked to at least one file with the .ocx extension, which includes the software (221) for remote control of the projection offering an ActiveX interface (222), allowing network access software (15) and web page scripts to run and control the .ocx file.
- the server (2) also includes a DHCP (Dynamic Host Configuration Protocol) server (21), which allows the connection of the terminal (1) to the server (2) by a Wi-fi network, and video software (23), which directly receives from the terminal (1) the video data (11) transmitted during the execution of the .ocx extension file and which broadcasts them to the video projector (3) by wire connection (5).
- the video projection method according to the invention comprises a first step of execution of the network access software (15) on the terminal (1) by the user of the terminal.
- the terminal (1) is a portable computer, the latter will seek to connect to a wireless network (4), for example the Wi-fi network, by seeking the nearest DHCP server, which will assign a dynamic IP address.
- the second step of the method consists in entering into the network access software (15) on the terminal (1) the URL address corresponding to the website (22) hosted by the server (2).
- the terminal (1) connects (61, 62, 63) then to the website (22) of the server (2) via the wireless network (4), via the network cards (10, 20) of the terminal (1) and server (2).
- the web page to which the .ocx extension file is linked is then loaded (64, 65, 66) into the network access software (15) of the terminal (1) via the wireless network (4), via the network cards (10, 20) of the terminal (1) and the server (2).
- Said web page, to which the .ocx extension file is linked, which includes the remote projection control software (221), is therefore loaded into a memory of the terminal, with the .ocx extension file, at the place provided for the web pages of the network access software (15).
- the .ocx extension file is executed spontaneously.
- the instructions in the .ocx extension file comprising the remote projection control software (221) are interpreted directly in the language of the network access software (15) and are executed by the operating system (12) (for example Windows) from the terminal (1).
- This execution allows the sending (67, 68, 69, 70, 71) of the data video (11) intended to be displayed on the screen (14) of the terminal (1), on the one hand, to the video card (13) associated with the screen (14), on the other hand, through the network card (10) from the terminal (1) to the server video software (23) via the wireless network (4).
- the video data are converted by the remote projection control software into a format understandable by the video software (23) of the server (2) before being sent to the server (2).
- the video software then transfers (72) the video data to the projector (3) by the communication means (5).
- the .ocx extension file optionally compresses the video data before sending it to the server (2).
- the video software (23) decompresses them before the step (72) of transmission to the projector (3).
- the .ocx extension file does not execute spontaneously but following an action of activating a button, for example "ON / OFF", displayed on the web page, by example by a mouse click, this action of activating the button causing the execution of a script written for example in Javascript language, which launches the execution of the file of extension .ocx.
- the server (2) is integrated into the projector (3).
- the wireless network (4) is replaced by a wired network.
- the server (2) is therefore also equipped with a suitable module, for example ADSL.
- ADSL a suitable module
- the network access software such as the Internet Explorer browser
- the data video (11) intended to be displayed on the screen (14) of the terminal (1) are transmitted to the server (2), which is connected to the video projector (3) and which contains the video software (23), for example type VNC viewer
- the .ocx extension file including the remote projection control software runs without the need to install it on the terminal (1).
- the .ocx file including the remote projection control software is deleted from the terminal's RAM (1).
- Video projection is only possible later if a new network access to the HTTP server containing the web page (22) defined by the determined URL address is made by the user of the terminal (1) by launching the access software.
- network such as Internet Explorer, with the determined URL address.
