- the present invention relates to a device and a method for exploiting information in a database and to associated products.
- each user has multimedia tools allowing the interactive exploitation or manipulation of audio, video, graphics, etc. data.
- a television device endowed with high level polymodal processing specificities (sound, visuals, graphics, etc.), can thus be linked to an information processing system (processor, network) and also be coupled to a personal digital assistant. or PDA (for “Personal Digital Assistant”).
- PDA Personal Digital Assistant
- the latter offers a clearly higher quality of data display and processing (processor, memory) than that of the television device.
- Such a home network in particular when it uses the IP standard (for “Internet Protocol”), therefore makes it possible to transmit multimedia information inside the house. It is connected to the outside world (to the Internet) through a gateway, responsible for managing the transition between the internal network space and the Internet space by re-addressing IP frames from the outside to the interior and vice versa.
- the home network possibly has an access point allowing the attachment of devices, for example PDAs, by a wireless link (or more).
- a user can, through a local application and by means of the devices mentioned above, choose films, music or other types of files or information, from a remote database.
- a remote database can be very complex. For example, for video on demand, this usually includes several thousand films, which can go up to 300,000 units.
- the present invention relates to a device for exploiting information from a database, which makes it possible to obtain user-friendly and efficient data from the database, while being able to require only reasonable processing means even when the database is very large.

- the term “automatic” here means that at least some of the operations carried out by the means concerned are automatic.
- the term “representation” covers visual representations, such as in particular a screen display, and / or auditory representations, such as in particular the audio diffusion of information.
- the terms “representation space” must be considered as being able to designate not only a spatial space, but also of any other nature, for example based on dimensions of sounds and / or colors.
- the operating device of the invention contrasts with known techniques, because it relies on a close coupling of the use of the representation space and the data elements which are placed there.
- a spatial space for example on a screen
- the forms obtained then naturally follow from the nature of the data.
- a data set in a predefined form, for example on a plane or a sphere.

- modules shown are functional units, which may or may not correspond to physically distinguishable units.
- these modules or some of them can be grouped in a single component, or constitute functionalities of the same software.
- some modules may possibly be composed of separate physical entities.
- FIG. 12 and 15 to 19 showing examples of representations on PDA and television
- the dimensions of the elements of the cards are not to scale, but are chosen so as to facilitate reading and to clarify the presentation.
- An audiovisual device coupling architecture ( Figure 1) involves a MAST master device and a SLAV slave device, the MAST master device being able to control functionalities of the SLAV slave device.
- An access control device 1 governs the access of these two MAST and SLAV devices to a database 5. Although this device 1 is represented outside of the MAST and SLAV devices, it may or may not be wholly or partially incorporated into one or both. Its separate representation is therefore based on a concern for clarity in the presentation, and must be interpreted in terms of functions either concentrated or more or less distributed.
- the access control device 1 comprises in particular (FIG. 2) a module 11 for representing information from the database 5 in the MAST and SLAV devices.
- the module 11 is able to represent at least three hierarchical levels of information NU, NI2 and NI3 respectively of orders 1, 2 and 3 (the priority of the levels decreases in order, the notation "NI" being adopted as generic). This representation is made visually, by screen display and / or auditory, by sound diffusion.
- the representation of information from one of the levels is conditioned by a selection of data carried out in at least another of the lower order levels.
- the representation of the NI2 level depends on the data selected at the NU level
- the representation of the NI3 level depends on the data selected at the NI2 level (and indirectly, of those previously selected at the NU level).
- a default representation is however possible for at least one of the order levels higher than 1, insofar as certain data can play a central role in the order level immediately higher than the current one.
- the information represented for the NI2 level may contain data that by default conditions the information to be represented for NI3 level. Only an explicit selection of data other than the latter then modifies the information of the NI3 level.
- the representation module 11 is capable of simultaneously representing two distinct levels of information respectively in the MAST master and SLAV slave apparatuses. In combination with the other functionalities of the control device 1, it allows users to have a coupled representation between at least one level of lower order in the MAST master device and one level of higher order (relatively to the lower order) in the SLAV slave device.
- the access control device 1 also includes: - a selection module 12 allowing a user of the MAST master device to select data in the information levels, except in the highest order - so here in the NU and NI2 levels; a hierarchical determination module 13, capable of determining the information to be represented for any of the information levels, except that of the lowest order (here, NU), as a function of data selected by a user of the 'MAST master device in at least the next lower order level; this module 13 thus makes it possible to establish for each of the levels NI2 and NI3 to be represented in one of the MAST or SLAV devices, the information actually selected to be disseminated to users; - And a representation sharing module 14, capable of causing a double representation in the SLAV slave device and the MAST master device respectively; a lower order information level being represented in the MAST master device, the sharing module 14 is provided to react to a selection of data by a user of this MAST master device in this lower order level, by being able to immediately cause the representation of the
- an autonomous elective distribution device 2 includes the hierarchical determination module 13 and the sharing module representation 14 of the access control device 1, as well as an information extraction module 16 from the database 5.
- the information extraction module 16 is intended to extract the data suitable for representations in the MAST-A and SLAV-A devices, according to the instructions produced by the modules 13 of hierarchical determination and 14 of representation sharing.
- the representation module 11 of the device 1 is split between two representation sub-modules 11M and 11 S, respectively present in the master MAST-A and slave SLAV-A devices.
- the selection module 12 is itself integrated into the master device MAST-A.
- an essential part of the processing intelligence is thus concentrated in an autonomous system (the elective distribution device 2), which can for example be locally integrated in a user or be arranged at a remote server.
- the SLAV-A slave device is content with traditional representation functions based on the information communicated by the extraction module 16.
- the MAST-A master device in addition to this representation function, also includes selection functions in the levels NI information represented there.
- the extraction module 16 does not only send the appropriate data to the MAST-A and SLAV-A devices, but also sends them in the desired form for display and / or sound diffusion, by incorporating therein.
- interactivity data for example according to the DVB-MHP standard - for “Digital Video Broadcasting - Multimedia Home Platform” intended for selections in the MAST-A master device.
- the roles of SLAV-A and MAST-A devices with regard to access control are thus reduced, so that they can consist of products commonly available on the market, without requiring any particular adaptation.
- the functionalities of the latter are entirely distributed in the master and slave devices, denoted respectively MAST-B and SLAV-B.
- the master device MAST-B integrates the modules 12 for selection and 13 for hierarchical determination, as well as a representation sub-module 11M similar to that of the first implementation mode.
- it comprises a reception sub-module 17M responsible for receiving the information coming from the database 5 with a view to selecting the relevant data for representation.
- the function of an 18M filter sub-module is to select, from the accessible data in the database 5 via the reception sub-module 17M, the information required for the representations.
- This filtering sub-module 18M is in particular conditioned in its actions by the hierarchical determination module 13.
- sub-modules we refer here as previously to functionalities dissociated between the two devices MAST-B and SLAV-B , and not to a physical subset of an entity. It is thus possible to define a reception module 17 and a filtering module 18, these modules being understood as grouping the corresponding functionalities present respectively in the two devices MAST-B and SLAV-B.
- the SLAV-B slave device comprises, for its part, the representation sharing module 14, in communication with the filtering sub-module 18M of the master device MAST-B.
- representation sub-modules 11 S, reception 17S and filtering 18S having functions similar to those of the corresponding sub-modules in the master device MAST-B.
- the representation sub-modules 11 S, reception 17S and filtering 18S form, with the representation sharing module 14, an elective representation device 3 specific to the SLAV-B slave device.
- This second embodiment can make it possible to avoid the use of a specific device, by means of adaptations of the MAST master and SLAV slave devices used. These adaptations are preferably based on software additions.
- the functionalities of the access control device 1 are, as in the second mode, distributed between the master and slave devices, denoted respectively MAST-C and SLAV-C.
- the representation sharing module 14 is here integrated into the master device MAST-C, and not into the slave device SLAV-C.
- the SLAV-C slave device includes the representation sub-modules 11 S, reception 17S and filtering 18S
- the master device MAST-C includes, in addition to the selection modules 12 and hierarchical determination 13, an elective representation device 4 specific to the master device MAST-C, which includes the representation sharing module 14, and the representation submodules 11 M, reception 17M and filtering 18M.
- the filtering sub-module 18S of the slave SLAV-C device receives instructions from the representation sharing module 14 of the master device MAST-C.
- the software additions are essentially concentrated in the MAST master device and can be significantly reduced in the SLAV slave device.
- the role of the slave SLAV device is further reduced, the master device MAST itself performing the filtering and representation preparation operations making it possible to determine the content and the presentation of the data to be represented by the device.
- SLAV slave The result of these operations can be communicated in the form of instructions for accessing the database 5, for example in the form of interactive data in DVB-MHP format. It therefore becomes possible to be satisfied with a standard device with interactive functions for the SLAV slave device, the software additions being carried out exclusively in the MAST master device.
- a VOD software architecture ( Figure 6) uses XML (for “eXtendible Markup Language”) in terms of the representation of data and commands exchanged between different devices. These latter consist in the example shown, of a television set denoted TV and of two PDAs respectively designated by PDA1 and PDA2. These devices are respectively attached to processors 24, 26 and 28 responsible for interpreting the data and generating displays relating to these. They also have message handlers, respectively rated 23, 25 and 27.
- XML for “eXtendible Markup Language”
- the application can use local data, internal to the home network, or remote, produced by an Internet server external to the home network or hosted by a service provider.
- the data are thus available from a SERV server assembly comprising a server 21, as well as a session manager 22 capable of managing any application session involving the server 21 (local or remote).
- NI levels of information there are three NI levels of information: a first NU level allowing users to schematically view film indicators and make a selection; a second level NI2 showing, for each film selected, films neighboring the latter (according to the criteria explained below); and a third level NI3 giving various information on the selected film.
- One of the master devices (PDA1 or PDA2) sends for example the request for a new “deal” of films. This message is transmitted to the slave device (step E1 of FIG. 6) which transmits it first to the server 21, then to the other PDAs possibly connected (step E2).
- PDA1 or PDA2 sends for example the request for a new “deal” of films.
- This message is transmitted to the slave device (step E1 of FIG. 6) which transmits it first to the server 21, then to the other PDAs possibly connected (step E2).
- PDA1 or PDA2 sends for example the request for a new “deal” of films.
- This message is transmitted to the slave device (step E1 of
- the results are returned by the server 21 (step E3), they pass through the slave device (TV), which in turn sends them back to all the masters (PDAs, step E4).
- TV slave device
- PDAs masters
- step E4 Each is configured according to the application.
- the devices including the TV (in the first state of the interface it presents the NU level of the application), build the received VOD card.
- the TV slave device decides to use the information of levels NI2 and NI3 (details of the film and neighborhood) .
- the first master device that issued the action and the second master device also receive this information, but they do not process it, because it remains at NU level.
- the three devices first receive a film deal according to the NU level ( Figure 8).
- a user of the PDA1 device selects a film, film 1 ( Figure 9).
- a user of the PDA2 device selects another film, film 6 ( Figure 10).
- each of the PDAs incorporates a pointing device allowing a user to interact with displayed graphic elements, and the interfaces of the devices are based on the UPnP service (for “Universal Plug and Play”).
- UPnP service for “Universal Plug and Play”.
- a Java language program acts as a UPnP checkpoint and communicates with a Flash-based player to govern the user interface.
- PDAs preferably incorporate video control according to the MPEG 4 standard (for “Moving Picture Experts Group”), which allows interactivity to be integrated into video.
- the mode of navigation in the data will now be detailed in several exemplary embodiments.
- the three information levels NU, NI2 and NI3 described above are used, by associating the first NU level with NAV navigation maps and the second NI2 level with VOIS neighborhood maps.
- a device 30 for using information from the database 5 (FIG. 11) which is particularly suitable for representations of the NU level can be incorporated in the representation 11, extraction 16 and / or filtering 18 module of the exhibits upper.
- This operating device 30 essentially comprises a module 31 for selecting data from the base 5, and an arrangement module 32 for the data selected for the attention of users, in a representation space 40.
- the representation is visual, so that the space 40 is spatial.
- the spatial space can also have three dimensions (relief), or possibly only one (line of visualization), although the interest in the latter case is then quite limited.
- a similar technique is applicable in particular to an auditory representation, the space then being sound (for example, sound diffusion of information in two dimensions, comprising a first dimension of pitch and a second melodic dimension, with possible progressive evolution. according to each of these dimensions).
- a combination of several heterogeneous dimensions is also possible, for example a four-dimensional space comprising two spatial dimensions, a color dimension and a sound dimension.
- the space 40 is delimited so as to be entirely accessible to a user, and is explicitly provided for his attention. It comprises a plurality of positions suitable for receiving elements representative of the data in the base 5. These positions correspond to a discretization of the space 40 according to its dimensions.
- the arrangement module 32 is therefore provided for positioning in certain of these positions, elements representative of the data selected by means of the selection module 31.
- the selection modules 31 and arrangement modules 32 comprise several units intended to act in cooperation during each representation to a user.
- the arrangement module 32 comprises in particular a preliminary definition unit 33 of at least one related representation area within the space 40. This area or these areas
- the preliminary definition unit 33 can be produced in various ways, including random definition, drawing of zones by a user, selection of zones by a user from different available zones, etc.
- the selection modules 31 and arrangement 32 respectively comprise an initial specification unit 34 of at least one element priming data for each of the connected zones Z and Z ', and a unit 35 for positioning these priming elements respectively in priming positions P and P' of the connected zones Z and Z '.
- These starting elements for example obtained as a function of a user profile, constitute starting points for filling the connected zones Z and Z '.
- the preliminary definition 33, initial specification 34 and positioning 35 units together form an initiation block 41.
- a unit for successive determinations 36 of new data elements is capable of extracting data from the base 5, from the elements already positioned in the related zones Z and Z '.
- This unit 36 extracts the data in accordance with at least one proximity order relationship based on the contents of this data.
- a successive positioning unit 37 of the new data elements thus determined places these elements in positions not yet occupied by the connected zones Z and Z ′, in positions close to the positions occupied by the data elements already selected.
- One proceeds to a progressive filling of the connected zones step by step, with for engine the relation of order of proximity. This iterative process converges with the end of the filling of all the related zones (or possibly, in an uninteresting case, with the exhaustion of the data).
- the successive determination units 36 and successive positioning units 37 together form a recursive block 42.
- the latter is closely linked to the content of the data itself, and is applied iteratively. It allows to classify all the data elements in relation to any of them, several data elements being able to be assigned the same level of proximity. For example, if the data elements relate to music, the order relation with respect to a reference music (element already positioned) classifies the music according to the number of common notes, or common chords possibly transposed, or common melodic sequences of at least three notes possibly transposed, with this reference music.
- the system sets up NAV navigation maps, based on TAB tables which allow their graphic construction.
- the NAV navigation maps are previously constructed in space, their contents being generated by the system being implemented and adapted to the request of a user.
- each NAV navigation map is coded using a TAB navigation table made up of “1” and “0” as in the example below: 0110000101 0111100101 1111100101 0001101111 0011111111 0001110111 0001111101 1101110101 0011110101 0001110101
- Each element represents a film, materialized in the NAV navigation map associated with the TAB table in the form of a colored square indicating its genre.
- Each navigation mode uses this type of NAV navigation map in the data.
- N films are proposed to the user (N being equal to the number of "1" in the TAB table), selected randomly in the database but taking into account the constraints set out below. The user can at any time use a new random NAV navigation map, based on a new TAB table. In addition, the system randomly chooses the navigation table
- This TAB table serves as a support for the presentation of information. In the example described, it changes with each random request. Thus, the user can break with the previous data, because he immediately realizes that a new draw has taken place and that it is very different from the previous one.
- the prior organization of the NAV navigation map by means of the TAB table makes it possible to consolidate the interface system in a consistent reading mode.
- the squares representing the films are not placed randomly on the screen. They favor, in the first place, a better distribution increasing the comfort of reading and interpretation.
- This representation also borrows an analogy from the game of scrabble or dominoes. The user thus believes that he is in a free, instinctive navigation of the database, when in reality this navigation depends on the pre-built NAV navigation maps.
- each film is attached to eight neighbors.
- neighborhood relationships in a cardinal orientation mode, in the form of VOIS neighborhood maps such as for example the following:
- Neighbor 1 Neighbor 2 Neighbor 3 Neighbor ⁇ Film Y Neighbor 4 Neighbor 7 Neighbor ⁇ Neighbor ⁇
- VOIS neighborhood maps are used to fill the NAV navigation map and, on the other hand, are used for representations of the second level NI2.
- the neighborhood relationships are based on an algorithm which makes it possible to classify all the films according to an analogy link with the film Y.
- the algorithm is based on a number of terms common in the titles of the films, a number of common actors, differences in the years of production and / or a semantic analogy of the summaries of the films (for example number of identical or similar terms, excluding common words to be excluded from the account).
- One thus establishes an order relation in the films other than the film Y, determined with respect to this film Y and being able to include several films at each level of analogy with Y.
- the eight neighbors Voisinl to Voisin ⁇ respectively target the eight films having strongest analogy with Y, ranked in descending order according to the order relation used.
- a particular case of algorithm making it possible to establish an order relation based on a semantic analysis is described in document EP-A-1365583.
- the navigation map NAV can be used by the system on the basis of these neighborhood relationships to provide the user with a selection of films taken from preset paths, as described below. he In this way, a cartography is progressing, progressively adding neighbors, building a very dense network of films "corresponding" to each other.
- the system first selects a film, randomly from the global database or from a set extracted according to the user profile. This film constitutes an entry point in the NAV map, and allows to materialize one of the squares. From this initial film and following the indications in the TAB navigation table with the “0” and the “1”, the user progressively chooses which neighbors are presented by means of the VOIS neighborhood maps. For example, if the TAB navigation table indicates that you must take the neighbor “EST” (on the left) of film Y in the diagram above, the film “Neighbor” of the VOIS neighborhood map is selected and presented to where the TAB table defined it.
- the entry point of the TAB table is the first non-zero element of the upper line, going from left to right.
- the position of the element “Film Y” thus constitutes a starting point, and the TAB navigation table indicates to take exclusively the neighbors west, southwest and south (underlined below): 0 1 1 0 0 0 0 0 1 1 1 1 1 0 ...
- the system uses the VOIS neighborhood map centered on the film Y, by extracting the neighbors concerned: Film Y Voisin4 Voisin ⁇ Voisin ⁇ and positions them in the NAV navigation map.
- the system continues its action by continuing to read the TAB navigation table. He chooses one of the neighbors and repeats the same operation. It therefore begins by searching for the latter's neighbors and reads the TAB navigation table which indicates which ones are displayed (this cartographic system used to direct searches in the base).
- the path constructed by the TAB table "discriminates” the selection in the database according to a so-called “random” mode, which provides a sort of "nomadic" route (the user takes directions at random in neighborhood relationships).
- the neighbor chosen after Y is Neighbor4.
- This implementation allows to pass from a random extraction to a random path in a neighborhood system.
- the NAV navigation map obtains a predominantly local coloration, the “Film Y” element often, but not necessarily, having neighbors of the same kind.
- the squares, representing the films and their genres, are therefore often the same color in a local vision of the map, but color changes can occur from one neighbor to another. If a neighbor is of another genre, he also sets up a neighborhood with this new genre as dominant, in his local space formed by the VOIS neighborhood map. As indicated above, it is preferable to avoid the repetition of films on the NAV navigation map, by eliminating from the list of available films those already selected previously, as the filling of the map progresses.
- each VOIS neighborhood card except the first integrates not only the element from which a neighborhood must be established (central element), but also the neighboring elements already known. , previously used for the route in the TAB navigation table. These elements are then placed in their respective positions with regard to the NAV navigation map, the VOIS neighborhood map being represented in this form on the screen.
- the element Voisin4 already has its neighbors to the west (Y), to the southwest (Voisin ⁇ ) and to the south (Voisin ⁇ ), and therefore only its five other neighbors are missing, to obtain the neighborhood map. VOIS to exploit and represent. Finally, only one of these neighbors (that of the south-east) is used to fill the NAV navigation map.
- NAV navigation maps NU level
- VOIS neighborhood maps NI2 level
- specific INFO information on selected films NI3 level
- the representations of the cards on the PDA and on television are identified by the terms PDA and TV respectively in parentheses.
- the PDA user acting as the master device requires the drawing of a NAV navigation map.
- the NAVO infrastructure (PDA) of such map ( Figure 12) is then used on the PDA in the form of a square assembly of 8x7 elements, themselves in the form of small squares representative of films.
- the PDA then randomly draws a navigation table TAB1 ( Figure 13) formed of "1" (presence of films) and "0" ⁇ (not shown in Figure 13, absence of films), among various tables available.
- the PDA To fill the NAV1 navigation map associated with the TAB1 table ( Figure 14), the PDA first automatically selects an F1 film from the database, which it positions at the first "1" encountered by scanning the lines from top to bottom and from left to right (here, this is the second square of the first line). Then, the PDA builds a neighborhood map VOIS1 of 3 ⁇ 3 elements centered on this film F1 by means of a neighborhood algorithm, and positions in the map NAV1 the films ⁇ corresponding to the elements identified by “1” on the table TAB1. The PDA repeats these operations step by step, successively centering the VOIS1 neighborhood cards on different neighbors.
- NAV1 navigation map (PDA) which is displayed on the PDA ( Figure 1 ⁇ ) .0
- PDA NAV1 navigation map
- Figure 1 ⁇ Another illustrative example will make it possible to follow the types of complementary display represented on the PDA acting as master device, and on the TV acting as a slave device.
- a NAV2 navigation map being displayed on the PDA in a similar way to the NAV1 map (in ⁇ Figure 1 ⁇ ), this NAV2 map is immediately shown on the TV, in an exploded NAV2 (TV) form ( Figure 16).
- the TV display is not however reduced to this NU level information, already present on the PDA, but also includes a NI2 level representation showing a VOIS2 (TV) neighborhood map.
- This VOIS2 map determined similarly to the VOIS1 card mentioned above, is centered on a film Fi which is the one on which positions the user of the PDA. At this point, however, the user has not yet made any film selection in the NAV2 navigation map.
- the VOIS2 map also includes a film F (i-1) (called “father film”) positioned before the film Fi during the construction of the navigation map carte NAV2, and from which the film Fi was obtained by relation of neighborhood.
- the VOIS2 neighborhood map (PDA) is displayed on the PDA ( Figure 17).
- the display on the TV is then automatically modified ( Figure 18), to include not only the NAV2 navigation map (TV) and the VOIS2 neighborhood map (TV) associated with the selected Fi film, but also INFO information (Fi ) relating to the film Fi.
- This NI3 level INFO information is established by default, since it is directly derived from the choice of the PDA user at NU level.
- the information INFO adapts to be representative of this film.
- maps other than NAV navigation and VOIS neighborhood maps are also useful. These maps have fixed shapes and offer a static mode of data interpretation.
- a “Past” card stores the extractions previously made by the user in the database and used by diffusion of the corresponding films - by way of illustration, this card has a pyramidal shape (for example of 8 elements at the base , 2 at the top and 4 at the top).
- a “Future” card contains indicators of films that the user wishes to see later - by way of illustration, it has a square shape (for example ⁇ x5 elements) .0
- highlighting of the elements of these "Past" and “Future” cards is possible according to time indications required by the user. For example, a list of months of the year is displayed opposite these cards, and allows the user to select one of the months to see the films already watched ("Past" card) or to watch. (“Future” card) during this month.
- a user uses a stylus 60 to make a selection on a grid associated with the blank NAVO infrastructure (PDA) of the navigation map NAV.
- the system analyzes this plot and converts the selected points, thus producing (FIG. 20) a navigation table TAB3 comprising an area Z3 of "1" derived from the layout, and intended to accommodate the films.
- each NAV navigation map can have several related shapes, without contact with each other.
- a film is for example chosen at the start for each of the related forms of the navigation table TAB, then used to fill this connected form step by step, in the same manner as explained above.
- the data initially chosen for these starting points themselves have a link of analogy with each other. For example, they are linked together by a neighborhood relation based on ⁇ on the same algorithm as that used to fill the connected forms.
- SLAV slave device for one or more MAST master devices
- PDAs master devices
