Description

<Desc / Clms Page number 1>

The present invention relates to a method for controlling the display of a multimedia document as well as the definition of such a multimedia file. It applies for example to communication terminals, or more precisely to radiocommunication terminals, pocket computers or any other device which may have multimedia capabilities and for the dimensions of its display screen may not be known. .

 The term multimedia file generally refers to the integration of data of different types (such as images, sound, text or others) in the same file. Each type of data can be contained in a given track.

Each track can be organized as a series of commands. Each track is reproduced to the user by one or more microprocessors. The microprocessor (s) execute, at the same time, the commands and can present the data, through different interfaces (microphone for sound type data and display screen for image or text type data), to a user of a multimedia device. Data intended to be displayed on a screen and belonging to different tracks must be displayed in different areas of the screen. These display areas are also called video areas.

 In the state of the art, the display of these video zones can be carried out according to the technique used, for example, by the Apple company or the Microsoft company. This technique is used for the display of all data on a computer screen.

 FIG. 1 represents a screen of a computer using this display technique. Screen 10 must display a multimedia file made up of two tracks, one containing image type data intended to be displayed in a first zone 20 and the other containing text type data intended to be displayed in a second zone 30. This screen has a height of X = 600 pixels, also called screen points, and a width of Y = 800 pixels. Each pixel is located in a frame consisting of a center 0 of coordinates x = O and y = O located at the top left of the screen, a horizontal axis 40 located on the top of the screen and a vertical axis 50 located on the left of the screen.

The first zone 20, with four vertices, is defined by the coordinates (x ', y') of the vertex 0 'located at the top left of this zone 20, by its height Il = 200 pixels

<Desc / Clms Page number 2>

et par sa largeur L1 =100 pixels. Si l'utilisateur veut afficher cette image en haut de l'écran et à 50 pixels du bord gauche 50 de l'écran, alors les coordonnées (x'=50, y'=O), H1=200 et L1==100 sont transmises au gestionnaire d'écran. Ce gestionnaire d'écran, généralement un système d'exploitation, va alors afficher la zone 20.

and by its width L1 = 100 pixels. If the user wants to display this image at the top of the screen and 50 pixels from the left edge 50 of the screen, then the coordinates (x '= 50, y' = O), H1 = 200 and L1 == 100 are transmitted to the screen manager. This screen manager, generally an operating system, will then display area 20.

 The second zone 30, with four vertices, is defined by the coordinates (x ", y") of the vertex 0 "located at the top left of this zone 30, by its height H2 = 30 pixels and by its width L2 = 150 pixels If the user wants to display this image at the bottom right of the screen right against the left edge 50 of the screen, then the coordinates (x "'= O, y"' = 600-30), H2 = 30 and L2 = 150 are transmitted to the screen manager. This screen manager will then display the zone 30.

 To display areas with this technique, you have to find out from the operating system the size of the screen and do coordinate calculations to position the areas, even when you want to display several video zones 21 to 26 inside zone 20. In the case, it is necessary to know precisely the coordinates, with respect to the vertex 0 ′ of zone 20, of the vertex located at the top left of each video zone 21 to 26 to be included. The size of zone 20 must be recalculated, by the operator, so that this zone 20 surrounds zones 21 to 26.

 The object of the present invention is therefore to display different video zones while respecting their original presentation and the display of all of the information that they comprise while overcoming the drawbacks of the prior art.

 To this end, the subject of the invention is a data file for the definition of the objects to be presented, data capable of being transmitted by a transmitter intended for a receiving terminal comprising a presentation device, characterized in that said file comprises command information for defining a presentation area on said presentation device of the receiving terminal, these commands containing parameters for identifying the number of objects in width and / or height and / or depth so as to define the size of said presentation area.

 The invention also relates to a data file characterized in that it comprises fields indicating the number of objects in width and / or height and / or depth so as to define the size of said presentation area, and the positioning of the presentation area on the presentation device of the receiving terminal.

The invention also relates to a method for displaying data forming objects to be displayed on a display device, managed by an operating system and comprising at least a first display area intended to display at least two data types in respectively two second subzones located inside the first zone, characterized in that, the method includes a step of defining said first zone by the operating system as a function of the size of the second subzones so as to allow an adaptive configuration of the first zone around said second sub-zones.

 In another embodiment, the invention relates to a method for displaying data in which the first zone having undergone a first adaptive configuration around the second sub-zones, is reconfigured iteratively as a function of the taking into account. subsequent count of third subzones of sizes different from those of the second subzones.

 The invention and its advantages will appear more clearly in the description which follows, in conjunction with the attached figures.

Sur la figure 2, le terminal émetteur 1, distant ou programme informatique, est l'émetteur de la requête de définition d'une zone d'affichage ou l'émetteur du fichier multimédia contenant cette requête.

In FIG. 2, the transmitter terminal 1, remote or computer program, is the transmitter of the request to define a display area or the transmitter of the multimedia file containing this request.

 This request includes a command for defining a display area in width and / or height and / or depth.

 The receiving terminal 2, operating system or interpreter of a multimedia file, is the manager of the display area, receiving the request.

 FIG. 3 represents a multimedia file defined according to the invention.

 This file is composed of a field constituting the header of file 3, a field 4 containing data and command information and a field constituting the end of file 5.

 Field 4 presents commands 4a for defining a first display area, associated with commands 4a ', 4a ", as well as the data 4b intended to be displayed in this first area, then commands 4b for defining d 'a second display area and so on.

 FIG. 4 represents the definition of a display area according to the invention.

 The commands 4a for defining a first display area consist of defining the positioning of the display area on the display device of the receiving terminal, of the number of objects to be contained in width in the area d display, the number of objects to be contained in height in the display area and the number of objects to be contained deep in the display area.

 The commands 4a ', 4a "and 4a"' associated with the commands 4a, are respectively representative of the number of the display area, the number of dimensions of the area and other properties of the area such as its transparency or its framing. visual.

 These commands are not limited to what is described.

 These commands are coded so that the commands 4a occupy the bits of the computer control 6 numbered from 0 to 4, the commands 4a 'occupy the bits of the computer command 6 numbered from 5 to

<Desc / Clms Page number 5>

8, les commandes 4a"occupent les bits de la commande informatique 6 numérotés de 9 à 10, les commandes 4a''occupent les bits de la commande informatique 6 numérotés de 11 à 15.

8, the commands 4a "occupy the bits of the computer control 6 numbered from 9 to 10, the commands 4a" occupy the bits of the computer control 6 numbered from 11 to 15.

 In Figure 5, there is shown a first video display area 60 on a display screen 10 of the termina! receiver.

 The video zones 61 to 66 are intended to be displayed inside the video zone 60. In this case, for example, the transmitter of a multimedia file, to a recipient having the terminal composed of the screen 10, want each of the six tracks in this file to be displayed in each of the six areas 61 to 66 and for these six areas 61 to 66 to appear inside the area 60.

 The size of the video zone 60 is not physically defined at the start: the operating system is first of all informed that the zone 60 must frame six zones 61 to 66 of different size, respectively the zone 61 of height hl and length II, zone 62 of height h1 and length 12, zone 63 of height h2 and length II, zone 64 of height h2 and length 12, zone 65 of height h3 and length II, zone 66 of height h3 and length 12.

 In our example, hl = h2 = h3 = ll = 12 = 13 = 32 pixels, the total size of the area 60 must therefore be H = 32X3 pixels and L = 32X2 pixels, that is to say height 96 pixels and width 64 pixels.

 The size of the area 60 is therefore defined as a function of the size and the number of elements that compose it.

 In another case, in FIG. 6, the transmitter wishes the video zones displayed 61 ′ to 66 ′ to be of smaller size than the zones 61 to 66, the zones 61 ′ to 66 ′ being defined by, respectively, the zone 61 'high h and length Il', zone 62 'high h and length 12', zone 63 'high h2' and length 11 ', zone 64' high h2 'and length 12' , the zone 65 'of height h3' and length Il ', the zone 66' of height h3 'and length 12'. This is the zoom out technique well known to those skilled in the art.

 In this case, the zone 60 is defined as a function of the size of the zones 61 ′ to 66 ′. This zone 60 ′ will therefore have a reduced size compared to that of the zone 60. The zone 60 ′ is therefore automatically adapted to the size of the zones 61 ′ to 66 ′.
