Description

Method, apparatus and system for managing structured information within a graphic scene 1. Field of the invention

The field of the invention is that of access and transmission of contents and, more precisely, of graphic animation contents, between customer terminals forming receivers, such as radio telephones, electronic organizers (PDAs). , etc., and servers of such contents.

More specifically, the invention applies to a large number of applications, for example of the RichMedia type, which need to take into account a description of the spatio-temporal arrangements between the graphic objects defining a graphic animation content so that either perfectly restored on the client terminal (called receiver) the behavior of a graphic scene of a given application.

It should be noted that the technique of the invention can be applied in a nonlimiting manner to all types of descriptions of graphic animations currently existing, in particular: MPEG-4 / BIFS, SVG, SMIL, XHTML, etc.

As a preliminary remark, it should be noted that for the sake of clarity of the description, a certain number of technical information has been included in the appendix. It is understood that all of this information in these various appendices is an integral part of this description.

2. State of the art

Several techniques are known to date which make it possible to simultaneously process a database of structured information and a graphic scene based on such structured information and on a series of simple instructions making it possible to automate certain tasks and to define the behavior of graphic objects contained in the scene.

A major drawback of the use of such instructions is that they are part of a programming language (or script) which must necessarily be previously interpreted or compiled, that is to say previously translated into a binary language directly understandable by the processor of the terminal on which the graphic animation must be restored.

By way of illustrative and nonlimiting example, such a drawback today constitutes an obstacle to the possibility of recovering on a receiving terminal representative structured information, for example from an electronic program guide available from a television server terminal. digital and the direct presentation of this guide in the form of a corresponding graphic animation on the receiving terminal having required the display of such a guide.

Indeed, taking into account the entire program guide can not be done using the known solutions of the prior art without making a change in the programming and / or design of the player equipping the terminal. In addition, taking into account the information contained in this program guide can not under any circumstances be carried out in a single block of information, which has the additional disadvantage of implying on the contrary an iterative taking into account of the information contained in the program guide, with the consequent risk of desynchronization between the information available on the server at a time t and the return of the latter on the receiving terminal at a time t + dt.

The document "LASeR and SAF editor's study", INTERNET CITATION July 2005, XP002394535, discloses an architecture, a scene description format, an aggregation format, profiles and various sections including a formal description of a binary encoding. . In the scene description section, there are sub-sections on the time model, execution model, events, binary encoding, update commands, and scene description elements. However, this document does not describe any means of including external information, which would not be graphic scene information, within the graphics scene, as is the case with the present invention.

Finally, the document "An MPEG standard for rich media services" IEEE Multimedia USA, Vol 12, No. 4, October 2005, XP002412761, makes a presentation of the LASeR standard. This document describes rich media, LASeR main features, portal applications, interactive mobile TV, screen saver, LASeR components with SVG-like initial scene, extensions scenes, scene updates, binary encoding, audiovisual support, fonts, incremental scenes, aggregation format, and cache mechanism.

In this document, there is described a service aspect updated by the server where all the information is available in a LASeR format, which means that all the information is in the field of the graphic scene, contrary to the present invention which is proposes to simultaneously process a database of structured information and a graphic scene.

3 _; Objectives of the invention

The invention particularly aims to overcome these disadvantages of the prior art. More specifically, an object of the invention is to provide a simple technique or mechanism for managing structured information within a graphic scene, which:

• generic in terms of implementation;

can be integrated into any graphical representation in an uncompiled form, without requiring, as in the known solutions of the prior art, the use of a script interpreter such as ECMAScript, for example, or still the execution of a virtual machine JAVA (registered trademark);

"allows the establishment of a system for anticipating the management of structured information, in order to optimize the material resources required for the processing of the application, the invention also aims to provide such technical, which is simple and inexpensive to implement, while allowing to respond to the following technical problems: managing the variation of the volume of information in the structured information base used by the graphics rendering engine within the graphic scenes. anticipate one or more requests for valuation of graphic objects and interaction on the behavior of graphic objects. temporarily save the state of the structured information base in relation to the state of the graphic scene at a given time, minimizing the processing on the basis of structured information and structured information, in order to favor as much as possible the performance of the graphic rendering.

The technical interest of the invention can be summarized in the following three main technical points:

- reduction of the memory used; gain in the use of computing resources; - compatibility with conventional decoding techniques.

The invention also makes it possible to take into account, in graphic animation content, structured information possibly retrieved from a particular content server, without having a program or design constraint on the reader used on the client receiving terminal. Another object of the invention is to provide a technique that allows the taking into account of a structured information block in the multimedia scene description, or in the description of a graphic animation content and therefore, which avoids any risk of desynchronization of information as in the techniques known from the prior art. A last objective of the invention consists in providing such a technique that makes it possible to overcome any constraint of modifying the reader dedicated to reading the animation graphics content or the multimedia scene, or else any constraints of re- programming. 4. Summary of the invention These objectives, as well as others that will appear later, are achieved by means of a method of managing a plurality of structured information received by a client terminal, called a receiver, in response to a recovery request. a graphics animation content with a server terminal of such content. According to the invention, such a method advantageously comprises the following steps: sending a request for recovery of at least one graphic animation content by said client terminal, to said content server terminal; - Recovery by said client terminal of at least one description file of said graphic animation content, said file describing the spatio-temporal arrangement between the graphic objects of said animation content and comprising at least one information management function structured device capable of automating: the creation and execution of the request to assign at least one given value to at least one attribute of at least one of said graphic objects and / or the creation and execution of at least one of an interaction value with at least one of said graphical objects and taking into account said plurality of structured information.

The structured information management functions interrogate the database containing the plurality of structured information (for example those relating to the consideration or integration into a graphic animation content or a multimedia scene, d. an electronic program guide). It makes it possible to link a semantic information model and an information presentation model on a receiving client terminal.

Such an approach according to the method according to the invention also advantageously makes it possible to dispense with any scripting mechanism and any reprogramming of a content to be rendered on a terminal that has required it. The method also advantageously makes it possible to synchronize the rendering of a graphic animation content on the client terminal, by means of a deterministic model formed by the plurality of structured information taken into account by the management functions, which are directly embedded in the description file of the animation content or the multimedia scene.

In an advantageous embodiment of the invention, said plurality of structured information is stored in a memory of said receiving terminal. In a variant of the method according to the invention, said plurality of structured information is received by said receiving terminal from an independent structured information management server with respect to a plurality of graphic animation contents.

In this embodiment, the structured information management functions take into account an addressing link (preferably a URL) pointing to the various structured information to be used for the rendering of a predetermined graphic content, which are hosted on the network. independent structured information management server.

In a variant of the invention, the independent structured information management server and the graphics animation content server can be grouped together in the form of a single server. More specifically, the invention relates to a method for rendering a graphic animation content comprising the following steps, in a receiving terminal: transmitting a request for retrieval of said content; obtaining at least one graphic scene of said content, describing at least the spatio-temporal arrangement between the graphic objects of said content.

According to the invention, said content also includes at least one structured information management function for interacting with a structured information database, and said method comprises the following steps: interrogating said database, as a function of at least one command present in said graphic scene and associated with said structured information management function (s); obtaining structured information from said database; integrating said structured information into said graphic scene; restitution of said graphic scene.

Thus, the method according to the invention makes it possible to integrate in a graphic scene structured information derived from a database, that is to say information different from the description information of the graphic scene, and whose structure is known in advance.

According to a variant of the invention, said content and / or said structured information are stored in said terminal. Thus, the database structured information can be in the terminal, following a download prior to the rendering of the graphics scene.

According to another variant, said content and / or said structured information are stored in at least one remote server. Thus, the rendering method according to this variant interrogates one or more remote servers, on which are housed the graphic contents and the structured information database.

Preferably, said structured information is stored in a dedicated server, separate from the content server or servers.

According to a particular embodiment, the rendering method comprises a step of configuring a filter, initiated by one of said commands, which defines a subset of said structured information database, comprising the information to be presented.

Thus, the method according to the invention makes it possible to filter the structured information data to be loaded according to the graphic scene to be restored. Advantageously, the rendering method of the invention comprises at least one loading step, initiated following the step of configuring a filter, which defines the nature and the number of structured information data to be loaded. . Advantageously, said loading step is preceded by a step of positioning an index, initiated by a command that defines the loading order of the structured information data to be loaded.

Thus, after having defined the subset of information to be presented, via a filter, a command makes it possible to position an index defining the order of the data to be loaded, in a step of loading the data. This data loading step includes parameters defining the nature and number of data to be loaded.

Preferably, the rendering method according to the invention comprises: a step of detecting the success of loading the structured information data, generating success information; a step of updating said content on receipt of said success information.

Thus, the method detects if the loading was successful before updating the graphics scene with the loaded data. In this case (successful loading), said update step comprises a step of assigning a loaded data item to a field of an object of said graphic scene.

Thus, the objects of the graphic scene are updated, by assigning the loaded data to the corresponding fields, so as to integrate the structured information into the graphic scene.

In addition, in the case of detecting the success of the last data to be loaded, the method comprises a step of adding in said graphic scene an interactive descriptive element making it possible to signal to a user of said terminal the possibility of loading data. additional structured information. Thus, once the last data loaded successfully, an additional element is added to the graphics scene, to indicate to a user of the terminal that additional data can be loaded. Such an element may be for example an arrow indicating to the user that he can access additional information if he clicks on the arrow.

In the case of detection of a failure to load the structured information data, the method comprises a step of updating said content, delivering information representative of said failure. For example, the graphic scene may be updated by displaying instead where the structured information should have been embedded a sign indicating to the user that he does not have access to the information.

5. List of figures

Other features and advantages of the invention will emerge more clearly on reading the following description of a preferred embodiment, given as a simple illustrative and nonlimiting example, and the appended drawings, among which: FIG. 1 presents an example of architecture and exchange of flows between the different elements of the structured information transmission and management system within a graphic scene. FIG. 2 presents two examples of host contents for information imported from a structured information base; - Figure 3 shows the different steps of the method according to a particular embodiment of the invention.

6. DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION The general principle of the invention is therefore based on a method making it possible to integrate structured information into a graphic scene (or graphic animation content) to be rendered on a screen. customer terminal receiver.

The invention can in particular be used in a large number of applications that require a description of spatio-temporal arrangements of graphic objects to represent the graphic behavior of said applications and a structured information database updated regularly to enhance the graphic objects and interact on their behavior and thus semantically present the information to a user.

The object of the invention is therefore to describe a device for transmitting, decoding and processing structured information management functions (not providing a graphical indication) within graphic scenes (or animation graphics content). ).

Many use cases require the use of graphic scenes to present on a terminal structured information that is sent to said terminal by a different means.

According to the invention, Structured Information Management Functions (called FGIS by the inventors) within graphical scenes, described in this document, make it possible to manage: requests for valuation of graphical objects by the structured information, these requests for valuation for the purpose of assigning at least one value to at least one attribute of a graphic object contained in the scene or the graphic animation content (for example: setting the size of a rectangle object, changing the color of an object, to say to a graphic object if it must be visible or invisible, in transparency, etc.); simple instruction suites (of variable structuration level), allowing to automate the execution of these queries, their transmission and their reuse within several graphic scenes. Such a relatively "low-level" representation of the "management" functions makes it possible to have a fine interaction between the graphic scenes and the structured information sent.

The technique according to the invention advantageously makes it possible to gain in ease of maintenance on the creation of graphic animation contents.

In particular, the use of a mechanism integrated in the process of rendering graphics commands allows a strong dependence between the content and the use of the structured information and requires no additional debugging process (Le., search and if possible to remove errors) for the validation of the valuation requests (ie the attribution of at least one value to at least one attribute of the targeted graphic object) and interaction with graphic objects.

The following scenario gives an example of implementation of the invention in a given application context: a receiver requests a graphics animation content at the source (server A). the server returns content that describes the spatio-temporal arrangement of the graphic objects, in the form of a structured information block. in this latter content are integrated and described structured information management functions (FGIS). These can be arranged as a series of simple instructions capable of enabling the automation of valuation and interaction requests targeting at least some graphic objects of the graphic animation content required by the receiver (client terminal).

They indicate in particular that a set of structured information stored in memory in the receiver, will be accessible or not and that if necessary a treatment (Le., Valuation and interaction on a graphic object) will be performed. the structured information is received by the receiver via a server (server B) which may be independent of the server A. Different commands may be used to modify a set of properties of a scene at a given time.

The commands that must be executed at a time specified by the graphics scene are described as URLs activated following a user interaction. In order to modify the appearance of the graphic scene, the graphic objects to be enhanced, or which may be subject to interaction, must be referenced by a unique key (named ID or DefName according to the graphic scene representation techniques). Such commands make it possible to define the types of information used by the scene and the nodes of the latter which must receive this information.

They include a list of the elements necessary to obtain the structured information integrated in a multimedia scene description or in a graphic animation content.

An example of the syntax and semantics of such a command is given here for illustrative purposes: cmd: // <action>? <Xxxx> = <nnnn> & <yyyy> = <pppp> & ... Where:

<action> defines the type of query of the structured information base (or block);

<xxxx> and <yyyy> represent the types of information to look for; <nnnn> and <pppp> represent elements of this type of information. Another example of definition of nodes of a graphic scene is also given here for illustrative purposes: cmd: // <action>? <Xxxx> = <nnnn> & ... & idT = <yyyy> & idA = <zzzz> where :

<action> defines the type of action to perform on graphic objects:

• <yyyy> being the graphic object to modify;

• <zzzz> being the graphical object on which to interact if the information exists.

An example embodiment of the invention is presented here.

The operation of the structured information management method within a graphic scene can be described according to the following steps, in consideration of FIG. 1- Entering graphic scene description and structured information data via network connections or file reads;

2- Decompression of these data in order to obtain a description of graphic objects directly usable by an audio and graphic rendering engine;

3- Possible decompression of these data in order to obtain a description of the structured information elements directly usable by the modules interrogating the structured information base; 4- Composition of graphical objects together to create a graphic scene;

5- Activation of the commands describing structured information management functions (FGIS) according to the execution model used by the rendering engine (see Figure 1); 6- Processing orders describing the FGIS (see Figure 1).

7- rendering (the., Display of visual objects or game of a sound) audio and graphic objects;

8- Taking into account the user interactions (the., Click of the pointer, pressing of a key, etc.) and recording of the activations of the possible FGIS;

9- Establishing a connection to a local or distant information source if necessary;

10- Return to 1 if no stop mechanism is activated.

Thus, following a request from a user, the system according to the invention will open a connection to the server and recover a bit stream.

This bit stream will be analyzed by the player (or player) who will then create the graphic scene that will contain textual elements to render.

If a URL contains a command containing FGIS is parsed in the bitstream, then the drive will save it and run the FGIS before rendering the next representation of the graphic scene on the receiver (eg, direct representation of the pixels on the screen).

Such a new and inventive approach is particularly interesting in that it allows to take into account at the reader a block of structured information necessary for the return of a next representation of the graphics scene on the receiver, no more have to reprogram the player and therefore, in a totally generic way. All the "design" of a multimedia scene or animated graphic content is now directly performed in the scene or animation content. As summarized in FIG. 1, the operation of the FGIS management system and method according to the invention can be summarized by the following steps:

1- Retrieving structured information instructions from the rendering device.

2- Establishment of a connection to a source of local or distant information if necessary.

3- Querying the structured information database and storing responses to queries.

4- Waiting and processing orders describing the FGIS (see step 6 of the rendering, above). 5- Return to 1 if no stop mechanism is activated.

The method and system according to the invention advantageously makes it possible to confer on graphical scenes or graphic animation contents, for example of the "richMedia" type, the possibility of accessing structured information, by providing them with new commands directly. in their description, commands that will then be directly read and interpreted by a rendering engine, for example a CBMS rendering engine (according to the CBMS standard of the same name, for "Convergence Broadcast Mobile Services"). Such a method advantageously also allows: to overcome the programming constraint, all the graphic rendering of a scene now being integrated into the description file of the scene; to overcome any hard coding constraints of the scene, particularly with regard to certain categories of graphic objects; to no longer be constrained by the management of a limited and predetermined number of graphic objects in a scene.

According to the invention, a multimedia scene or a content of graphic animations is now able to: define filters on data; perform a selection of one or more objects by implementing a previously defined filter; to load in the scene graphical objects thus indexed on the realized selection; modify one or more indexes of the selection; - search for attribute values for a selected object; test the value of an attribute of a given object.

With reference to FIG. 3, the different steps of the method according to a particular embodiment of the invention will now be described.

The first step of issuing a request 31 is to issue a request to retrieve a graphical content from a server of such content.

In response to this request, the terminal receives at least one graphic scene of the requested content, comprising, in addition to the spatio-temporal layout information between the graphic objects, structured information management functions.

With these structured information management functions, the method queries, during a step 33 of interrogation, a database of structured information, through a command present in the scene. The sub-steps 331 for configuring a filter, 332 for defining the data loading and 333 for the loading request, included in the step

33, to select, from the structured information of the database 334, the information necessary for updating the graphic scene in question and then to load them, in a predefined order.

Depending on the result (success or failure) of the data loadings, the method updates the graphic scene during update steps 341 or 342 and then restores it during a restitution step 35.

Thus, the rendering method allows the integration of structured information in a graphic scene.

In a particular embodiment of the invention, within a system where the database of structured information is a television program information base that can be used for the constitution of an electronic program guide, it is possible to advantageously use contents such as those shown in Figure 2 to create the program guide.

Part (a) on the left of Figure 2 presents a screen for presenting a program. Part (b) to the right of Figure 2 presents a screen for presenting a summary version of the presentation of two programs from a list of programs. The use of the content of part (a) according to the invention is as follows.

There are graphical or textual elements in the content of which certain fields are intended to be replaced by information from the structured information database: the service name, the service logo, the presentation image of the program, the program name, the start and end times of the program, the name of the next program.

There is in the structured information base for each program at least some of the information above. The method described by the invention aims to transfer this information from the database to the presentation: a first command of type cmd: // Cbms_filterDef as presented in Appendix A, is present in the content for position a filter on the basis of information: for example, the content is intended to present the sport programs of the current day. The first order is therefore a filter that restricts the scope to "sport" type programs as of today. There can be a number of programs in this small area. A second command of the type cmd: // cbms_loadID as presented in Appendix A, is present in the content to load within this content, among programs corresponding to the filter, detailed information of the first program, namely name of the service, logo, image, name of the program, hours and following program. if there is a sport program for the current day, then a third command of the type cmd: // cbms_getattr as defined in appendix A, is present in the content to transfer the information loaded by the second command into the fields of the presentation: the string of the name of the service will replace the string <service name> in the presentation content, the logo of the service and the characteristic image of the program will be placed in the content, the names of the program, hours and following program will replace respectively the strings <Prg Name>, <Prg Prg Time>, <Next Name> and <Next Start Time>.

An incrementing mechanism makes it possible to use the same content when next invoking this content on the next program in the list of programs meeting the filter "sport" and "today".

For part (b) of Figure 2, the positioning of the filter may be the same. The second cmd: // cbms_loadID command will concern the name and logo of two programs. The third command cmd: // cbms_getattr will replace the texts <Name> and the images <Logo> by the names of the two programs concerned and their logo. The "previous" and "next" elements are buttons which shift the content into the list of programs affected by the filter.

Appendix A: New Proposed Instructions 1 - List of New Orders

1.1 Arithmetic commands

- SET cmd: // var_set? Name = variableName & value = X

-> Who defines and / or positions the value of a variable

- ADD cmd // var_add? Name = variableName & value = X -> Who adds X to the value of a variable - SUB cmd: // var_sub? Name = variableName & value = X -> Who subtracts X from the value of a variable

1.2 CBMS and Query Definition Commands cmd: // Cbms_filterDef? Name = filtername & expr = expression where:

"" Name "is a name that allows you to reference this filter later;

"Expr" is an expression in a query language understood by the CBMS parser.

The words suffixes by $ refer to Text nodes, they are to be replaced by the value of the node corresponding to the execution of the query. In the context of the invention, a plurality of additional following supplementary requests is defined: AHServices: all services ordered from a service number or "serviceNumber";

The following commands are used to load an ID block into the scene according to a given filter, and to activate nodes based on the existence or not of a part of the ID block. 1.3.1 Value-indexed The value-indexed command allows a scene-level atomic command to load a consistent set of data.

Thus we will access n elements corresponding to a given filter, to retrieve the IDs of these N elements and trigger nodes if there is an element or not. cmd: // cbms_loadID? type = agiventype & filter = filtername & index = variablen ame & idt = DEFS & ids = DEFS & idh = DEFS where:

"" Type "is a value, this can currently take the value" service "

Or "program" (required) "" Filter "is a reference to a pre-defined filter (required)

"" Index "is a reference to a pre-defined variable (required)""Idt" is a comma-separated list of DEFs that will receive the ID values of the n elements according to the filter defined from an index , (optional) "" idS "is a comma-separated list of DEFs that will be started if there is an ith present value in the query, (optional)""idH" is a list of DEFs separated by comma that will be started if there is no i value present in the query, (optional) 1.3.2 Indexed by ID The ID-indexed command allows a scene-level atomic command to load a consistent set of data.

This allows you to load a dataset so that the element with the ID ID is in the place indicated by the delta value. cmd: // cbms_loadID? filter = filtemame & type = agiventype & idindex = id & delt a = downstream & idt = DEFS & I ds = DEFS & idh = DEFS where:

"" Type "is a value, it can currently take the values" service "or" program "(required);" "Filter" is a reference to a pre-defined filter (required)

"Idindex" is an id (required);

"" Delta "is the offset that we want for the id given in the query." "Idt" is a comma-separated list of DEFs that will receive the ID values of the n elements according to the filter defined in from an index, (optional)

"IdS" is a comma-separated list of DEFs that will be started if there is an ith present value in the query, (optional) • "idH" is a comma-separated list of DEFs will be started if there is no i value present in the query (optional).

1.4 Retrieving a value from an item

Used to evaluate an attribute of a scene node from the value of an attribute of an element that is addressed using its identifier. cmd: // cbms_getattr type = agiventype & name = atributeName & target = DEF & IDS = DEF & IDH = DEF & ID = agivenID & format = idformat where:

"" Type "is a value, it can currently take the values" service "or" program "(required),""Name" is the name of the attribute to retrieve (required); "" Target "is the DEF of the node for which we will position the attribute if found (optional);""idS" is the DEF of a node that will be started if we find an attribute with a value of defined (optional) "" idH "is the DEF of a node that will be started if an attribute is not found or its value is undefined (optional)""ID" is the id of the element in question (required) "" Format "(optional) is a formatting of the attribute, no formatting if not present 1.5 Testing the value of an element

This makes it possible to test the value of an attribute of a given element. cmd: // cbms_testattr? type = agiventype & name = atributeName & value = avalue & IDS = DEF & IDH = DEF & ID = agivenID & format = idformat where: "" Type "is a value, this can currently take the values" service "or" program "(required)" "Name Is the name of the attribute to be tested (required) "" Value "is the value to which the attribute should be compared." "IdS" is the DEF of a node that will be started if the test is positive. (optional)

"" IdH "is the DEF of a node that will be started if the test is negative, or if there is no value (optional)" "ID" is the id of the element in question, ( required)

"" Format "(optional) is a formatting of the attribute, no formatting if absent.

2 - Abstraction of the structure
