Abstract

A method for displaying multimedia content on the screen of a multimedia terminal, the multimedia content being encoded by data included in a file stored on a server remote from the terminal in a format such that the entire file is required by an application supporting the format for generating a display of the multimedia content on the screen of the terminal, wherein the method includes: requesting by the terminal the transmission of an encoding of the display of the multimedia content into a defined rendering format; using by the server the file for generating the rendering encoding of the multimedia content according to the defined rendering format by the terminal; and transmitting by the server the rendering encoding to the terminal using a graphic interface sharing protocol.

requesting, by the multimedia terminal, a transmission of an encoding of the display of a desired portion of the multimedia content in a defined rendering format that is different from said first format;

selecting, by the server, a specific application from among a plurality of different applications associated with said server that is compatible with the rendering format defined by the multimedia terminal, in which each of said plurality of different applications is associated with a different rendering format;

processing, by the server, the file with said specific application to generate the rendering encoding of said multimedia content according to the rendering format defined by the multimedia terminal, in which said rendering format defined by the multimedia terminal enables the display of only the desired portion of said multimedia content on the multimedia terminal screen without requiring a transmission from said server to said multimedia terminal of the entire file coding said multimedia content; and

transmitting, by the server, the encoding of the rendering to the multimedia terminal using a Remote Frame Buffer protocol so that the desired portion of the multimedia content is accessed and displayed by the multimedia terminal.

2. The method according to claim 1, comprising storing by the multimedia terminal different defined rendering formats for different applications processing different file formats.

3. The method according to claim 2, comprising displaying, by the multimedia terminal, command buttons on a screen and associating a command of such a button with a transmission of a command to the server intended to control the use of the file by the server.

4. The method according to claim 3, wherein the transmission of a command to the server by the multimedia terminal is coded according to the Remote Frame Buffer protocol.

5. The method according to claim 1, wherein the multimedia content is a video, the method comprising transmitting by the server the rendering encoding of the video using, first, position data encoding a position of the video according to the defined rendering format and, second, the video data encoding the images forming the video.

6. The method according to claim 5, wherein the position and the video data are generated from a same memory storing the rendering encoding of multimedia content generated by the server according to a matrix encoding.

7. The method according to claim 5, comprising processing the position data generated to inhibit the transmission of video data.

8. The method according to claim 1, wherein the defined display format determines a size of the rendering dictated by the multimedia terminal on the screen to the multimedia content.

9. A server configured to store multimedia content in a file, said multimedia content to be displayed on a screen of a multimedia terminal, the multimedia content being coded by data included in the file stored on the server remote from said terminal in a first format such that the entire file is required by an application that processes said first format to generate a display of said multimedia content on the multimedia terminal screen, the server comprising:

a receiver configured to receive a transmission request, transmitted by the multimedia terminal, of an encoding of the display of a desired portion of the multimedia content in a defined rendering format that is different from said first format,

wherein the server is configured to select a specific application from among a plurality of different applications associated with said server that is compatible with the rendering format defined by the multimedia terminal, in which each of said plurality of different applications is associated with a different rendering format,

an application manager configured to process the file with said specific application to generate the rendering encoding of said multimedia content according to the rendering format defined by the multimedia terminal, in which said rendering format defined by the multimedia terminal enables the display of only the desired portion of said multimedia content on the multimedia terminal screen without requiring a transmission from said server to said multimedia terminal of the entire file coding said multimedia content, and

a transmitter configured to transmit the encoding of the rendering to the multimedia terminal using a Remote Frame Buffer protocol so that the desired portion of the multimedia content is accessed and displayed by the multimedia terminal.

10. A terminal comprising:

a screen for displaying multimedia content, the multimedia content being coded by data included in a file stored on a server remote from said terminal in a first format such that the entire file is required by an application that processes said first format to generate a display of said multimedia content on the screen;

a system configured to request a transmission by the server of an encoding of the display of a desired portion of the multimedia content in a defined rendering format that is different from said first format so that, subsequent to said request, the server is configured to

select a specific application from among a plurality of different applications associated with said server that is compatible with the rendering format defined by the terminal, in which each of said plurality of different applications is associated with a different rendering format, and

process the file with said specific application to generate the rendering encoding of said multimedia content according to the rendering format defined by the terminal, in which said rendering format defined by the terminal enables the display of only the desired portion of said multimedia content on the screen without requiring a transmission from said server to said terminal of the entire file coding said multimedia content, and

a rendering system configured to display the desired portion of the multimedia content on the screen,

wherein the terminal is configured to receive the encoding of the rendering from the server so that the desired portion of the multimedia content is accessed and displayed by the terminal, the encoding being transmitted by the server to the terminal using a Remote Frame Buffer protocol.

11. A method for displaying multimedia content on a screen of a multimedia terminal, the method comprising:

receiving, by a server, a request from the multimedia terminal of a transmission of an encoding of a display of a desired portion of the multimedia content in a rendering format defined by the multimedia terminal, wherein the multimedia content is coded by data included in a file, stored on the server remote from said multimedia terminal, in a first format such that the entire file is required by an application that processes said first format to generate the display of said multimedia content on the multimedia terminal screen, said rendering format being different from said first format;

selecting, by the server, a specific application that is compatible with the rendering format defined by the multimedia terminal from among a plurality of different applications associated with said server, in which each of said plurality of different applications is associated with a different rendering format;

processing, by the server, the file with said specific application to generate the rendering encoding of said multimedia content according to the rendering format defined by the multimedia terminal, in which said rendering format defined by the multimedia terminal enables the display of only the desired portion of said multimedia content on the multimedia terminal screen without requiring a transmission from said server to said multimedia terminal of the entire file coding said multimedia content, and
