Definitions
- the present invention relates to a method of broadcasting multimedia information elements, a receiver of multimedia information elements broadcast by this method and a user interface for consulting these information elements.
- the network is saturated and offers only a limited speed per user, so that response times are relatively long.
- This type of information is made up of pieces of information which generally concern a large number of users and network saturation problems arise from the fact that the same information is sent several times to different users, and this usually during the day, most often during off-peak hours.
- a smoothing of the network load would make it possible to increase the availability of the latter during periods of high use, without requiring an increase in its capacity.
- the present invention aims at this objective.
- the subject of the present invention is a method of broadcasting multimedia information elements in a network comprising a transmitter and at least one information receiver, consisting in: determining the class to which each information element belongs, according to a classification predetermined, to broadcast in advance a descriptor relating to each item of information, this descriptor characterizing the class of membership of the item of information; at the level of each receiver, to qualify on the basis of the descriptors received the potential of interest of each item of information, according to a user profile defined in the receiver, to disseminate the items of information associated with the descriptors previously used; in each receiver, to locally record each item of information according to the qualification operated on the basis of the descriptors. Thanks to the invention, a large part of the data of interest to users can be disseminated in advance, preferably during the night period, but also during the day period by taking advantage of the flow fluctuations which constantly occur in the use of a network.
- the device operates by identifying the poles of interest of each user, and local storage, at the level of each user terminal, of information elements likely to be of real interest for this user.
- information element or document applies to any form of information likely to be disseminated to a set of users: message, press release, information note, article of a journal or newspaper distributed in the form of a text file whether or not accompanied by digitized images, an audiovisual or radio program or program element; this concept also extends to the broadcasting of programs such as musical recording, digital photographs, literary works (in whole or in extracts), total or partial distribution of catalogs, dissemination of commercial information of all kinds, dissemination of multimedia entertainment programs ( interactive games).
- the invention applies to all audio-visual reproduction devices, identified below under the generic term of receiver: radio, mobile phone, portable music player, television set, microcomputer and in general any type of equipment allowing '' access the data disseminated, adapted to provide the service defined in this description.
- the method according to the invention consists, in other words, in transmitting, to all the receivers of the network, all the information elements likely to interest all the receivers and in selecting, at the level of each receiver , those of elements of information which are likely to interest a local user, in order to locally store only these interesting elements of information and make them available to this user.
- the invention increases in a very significant ratio the number of users on the network, by avoiding a multiplicity of successive individual accesses to the same element of information.
- each receiver evaluates each descriptor in order to determine whether the item of information characterized by this descriptor enters the poles of interest of the user whose profile is defined in the receiver.
- the receiver stores the descriptor of the information element in a list grouping together all the descriptors associated with the information elements selected.
- the receiver determines whether the received information element is present in the list of preselected elements, and, if the descriptor is in the selection list, the receiver stores locally the information element associated with this descriptor, unless said information element is already stored within the receiver.
- This storage can be temporary, that is to say that the information element is kept until consultation by the user, or definitive, in which case it is an archiving.
- the memory space used by the information element will be freed after access to this information element, which will make it possible to reuse the freed memory space later.
- each descriptor of piece of information will include an indication concerning the period within which this piece of information must be consulted , and that we will systematically free up space memory occupied by an item of information stored for consultation, that is to say not archived, and to which the user has requested no access within the corresponding time.
- each descriptor comprises the indication of the memory size required for the storage of the information element.
- This indication is useful if the local recording of the information elements is carried out within the limit of a storage capacity reserved for this use in the receiver.
- a threshold is then fixed which quantifies the capacity of the memory reserved for the storage of information elements in the receiver and which makes it possible to retain or discard an information element so that the sum of the memory sizes necessary for the local storage of each item of information retained remains below this threshold.
- one possibility consists in sorting the information elements by decreasing interest potential, according to a user profile defined in the receiver, and in recording said elements information based on the results of the sorting performed.
- the information elements present in the receiver memory can be cyclically overwritten by more recent information elements, within the limit of the capacity reserved for this purpose in the receiver.
- a unique identification number is used to identify any item of information which may be disseminated.
- This principle of identification by unique number makes it possible to avoid redundancy of storage of the elements of information and therefore to optimize the use of the storage capacity available at the level of the receiver. Without application of this unique identification principle, storage redundancy would be likely to occur in the case where the receiver is operated by several users (the same piece of information can be considered as being of potential interest for several users, it there is no need to duplicate it in the storage area of the receiver), and in the case where the same piece of information is broadcast successively by two separate sources (for example for a radio broadcasting application, first by a general source then by a specialized source). . • ⁇ . "
- the user profile is defined by constitution of information classes and definition of a level of interest of the user with respect to each of these. information keys.
- a classification of the information elements is thus made before their dissemination; when accessing each item of information, the class of membership of the item of information as characterized at the source is used to identify the user profile by statistical accumulation of the accesses operated by the user on each class.
- the degree of interest of the user for an item of information belonging to a class considered is deduced from the number of accesses already operated by the user for this class.
- the user profile is updated automatically according to the way in which the user consults the pieces of information stored in the receiver.
- the locally defined levels of interest are updated as follows: any consultation of an item of information increases the level of interest attached to the class to which this class belongs information element, any rejection of an information element lowers the level of interest attached to the class to which this information element belongs.
- any interruption established rather at the start of consultation of an item of information is considered to be a rejection and reduces the level of interest attached to the class to which this item of information belongs.
- the number of accesses to an item of information can also be taken into account to update the level of interest attached to the corresponding class.
- the time spent consulting an item of information can be taken into account to weight the increment of the level of interest attached to the corresponding class.
- the user profile is refined as the user consults the elements of information offered to him by the receiver.
- the classes are organized in a tree structure.
- the first level corresponds to a type of program as "information” or “entertainment”
- the second level to a program area like “sports” or “cultural outings”
- the third level to a particular area of that area like “athletics” or “cinema” or “theater”.
- the number of classes that can be envisaged for classifying all of the information elements that can be distributed on a network is very large, it is considered that the number of branches and the depth of the tree structure depend on both the source of information (generalist source, financial, commercial news) and of the user's interest in each area covered by this source: the depth of the tree structure changes according to the level of user interest in the sector considered.
- the incrementation and / or the decrementation of the level of interest operated for a given class is accompanied by an incrementation of the level of interest associated with the classes of higher level, that is to say say located between the root of the tree and the class considered.
- the cumulation established at the level of a class considered is at least greater than the sum of the cumulations associated with the subclasses which are attached to it within the tree structure describing the profile of interest of the user and, when the cumulation associated with the root of the tree structure exceeds a fixed threshold, a decrement is determined for each level of tree structure on the basis of the difference between the cumulation associated with the root and the predetermined threshold , and this decrement is applied to each class belonging to the tree level considered, successively for each level of the tree.
- the receiver initially to have a standard profile from which it makes the first selections of information elements * in order to propose them to the local user.
- certain profiles can be oriented towards political and economic information, without the selection criteria being specified with regard to finer levels of detail in these two fields.
- the standard profile is loaded into the receiver by means of a removable device, of the magnetic card, smart card or any similar means of permanent storage.
- Such a removable device used for loading the standard profile can incorporate type data: right of access to the network, right of access to the broadcasting source, permanent or temporary archiving rights depending on the nature of the elements of , information relating to the duration and extent of these local access and archiving rights, encryption / decryption keys for exchanging information with the broadcasting source, profiles available in the event of multiple profiles type.
- the profile of each user is built in an incremental and implicit manner, from a standard profile, according to the nature of the consultations of the items of information operated by the user among the items selected by the receiver, the nature of the access made by the user - complete reading, partial reading, direct jump to the next item of information - making it possible to update the profile that the receiver associates with it, namely respectively incrementation, maintenance without modification, decrementation of the level of interest associated with the class considered.
- the user profile updated during the accesses operated by the user can be transferred to a removable medium of the magnetic card, smart card or any similar means of permanent storage, in order to be able to be reused on another receiver.
- each descriptor of an information element integrates the qualification of the level of detail corresponding to the information element (qualifying this element as information, from summary to very detailed).
- This indication of level of detail is de-correlated from the position within the tree structure: general information can be the subject of a detailed presentation, and very specialized information can be the subject of a summary message.
- the level of detail attached to an accessed piece of information can be used to weight the increment and / or decrement of the level of interest attached to the corresponding class.
- a return of the user to the broadcasting source can be provided in the form of a sending, coming from each receiver and bound for the transmitter, of an at least partial definition of the criteria for locally defined selection.
- the broadcaster can globally adjust its productions to offer programs more suited to the interests of all users.
- the feedback from the receiver to the broadcast source is established with a limit determined on the vision of the tree representing the poles of interest of the user, limit established in accordance with local regulations regarding respect for freedoms individual.
- the return of information from the receiver to the information source passes through an independent entity responsible for ensuring the non-recovery of data liable to infringe local regulations on respect for freedoms individual.
- the feedback is protected by encryption.
- descriptors are associated with the same piece of information.
- One piece of information generally covers several subjects; if all these subjects are part of the same domain, the descriptor will locate the information element in the class associated with this domain, but if the subjects are located in different branches of the tree structure, a descriptor is associated with each of the main subjects covered. This makes it possible to transmit a multiple descriptor (that is to say several descriptors) for the same item of information, and therefore several potential classifications within distinct classes.
- a relevance note is associated with each descriptor in order to qualify the validity of the ranking of this item of information within the class considered.
- This relevance score is used in the receiver to weight the potential interest of the information element for the user, as established from reading the statistical table representing the poles of interest of the user .
- the value of potential interest for a given item of information is the highest weighted value obtained from all the descriptors associated with this item of information. It is this value, also designated score, which is selected when the descriptors are sorted by potential of decreasing interest.
- the invention also provides a user interface which comprises in particular: means for consulting a proposed item of information, means for rejecting a proposed item of information, means to request access to information elements presenting a better level of detail.
- This interface can be constituted by a hardware device comprising at least three keys performing the functions described above or by a simulated graphical interface on a computer screen.
- the advantage of its definition is that it adapts to a large number of pre-existing screens or remote control devices whose keys respond to a known standard.
- the interface also includes means for returning to a previously consulted item of information as well as possibly means for archiving an item of information during consultation.
- the interface also includes means for causing the definitive or temporary storage of a previously consulted piece of information.
- This storage can be carried out either for the purpose of subsequent consultation, or for the purpose of pure and simple archiving.
- the interface can also comprise a means for signaling to the user the presence, in the storage memory, of at least one piece of information having a degree of detail finer than that of the item being consulted. .
- the interface can include a means of signaling to the user the existence, at the level of the broadcasting source, of at least one piece of information having a degree of detail finer than that of the item. during consultation.
- the interface comprises a control means allowing the user to make a request for access to an item of information not present in the local storage memory but present at the level from the broadcasting source, means which automatically send a request to the source. information, and the subsequent sending of the information element ' • ' from the source to the receiver.
- a repetitive action on the means of controlling access to the lower, respectively higher levels of detail causes systematic consultation of the levels of detail of the same level as the average level of detail in progress during these repetitive activations of the command.
- the present invention also relates to a receiver of multimedia information elements intended to be integrated into a network broadcasting information elements preceded by their descriptors according to the method described above.
- This receiver is characterized in that it comprises: means for receiving descriptors of information elements, characterizing the class to which each element of information belongs, means for qualifying potentials of interest of each element of information on the basis of the descriptors received, means for locally recording each item of information according to the qualification operated on the basis of the descriptors.
- the choice of the material structure of each of these means can be easily made by a person skilled in the art, who can in particular use a computer programmed in an appropriate manner.
- FIG. 1 is a schematic view of a system allowing the dissemination and reception of information elements in accordance with the invention
- FIG. 2 is a flowchart representing the different steps implemented by the invention
- FIGS. 3, 4 and 5 represent a tree structure of classification of information elements, at different stages of the learning process of the user profile
- the figure ⁇ represents a table of descriptors of information elements sorted by decreasing level of interest
- the figure 7 represents an example of an interface allowing the consultation of the elements of information disseminated and locally stored
- FIG. 8 is a graph showing a typical load curve on a multimedia access network as a function of time.
- the system represented in FIG. 1 comprises a hardware infrastructure constituted by a "gateway" 1, that is to say an assembly comprising a broadcasting server 2, a transmission chain 3 and an antenna 4.
- the infrastructure also includes a satellite or a constellation of satellites 5 capable of transmitting the signals received from the transmitting station to different receivers 7 distributed in a given region or over the whole planet.
- the receivers 7 are present in an unlimited number at different points in the region covered by the satellites.
- a single receiver 7 has been shown in FIG. 1.
- the processing of information elements by this system is as follows. Initially, pieces of information are produced by production units ⁇ . To facilitate understanding, the rest of the description will be based on information elements constituting radio programs, hereinafter called "broadcasts".
- the broadcasts are classified by the production units, then are stored in the broadcasting server 2, which transmits them to the satellites 5 at the times of best availability of the network.
- FIG. 2 the processing of the information elements is illustrated in FIG. 2, where each block, referenced 8 to 18, corresponds to the following steps.
- Steps 8, 9 The production units carry out emissions [#i] to which are assigned identifiers [ID # i].
- Step 10 For each program, a program descriptor is generated.
- This descriptor includes: the identifier of the program [ID # i], the duration [d] of the program, an indication of the classification of the program [a ;, b ;, q], the level of detail [ det] representative of the information processing detail, a relevance note [pert] to the classification of the program, possibly other classification values, detail and relevance, in the case of a multiple descriptor and finally, the program element [#ij itself.
- the classification of the program in the example described, consists of positioning it in a tree structure such as that represented in FIGS. 3, 4 and 5.
- the classification structure used comprises three levels of tree structure.
- each branch referenced t ,, t 2 , t 3 , corresponds to a particular type of program, for example: news programs, cultural programs, music program.
- each type of program tt 2 , t 3 is divided into areas of which three, dd 2 , d 3 , have been represented here.
- three areas can be considered for example: political information, sports information, cultural information.
- Each information domain is in turn subdivided into sectors, which constitutes a third level of tree structure.
- the classification of a program by its positioning within the classification structure is expressed in this case by a pointer consisting of three references ab i; q, each of which corresponds to a level of tree structure.
- the classification within the structure is associated with the indication of level of detail representative of the degree of detail with which the information is processed, for example 1 for summary presentation to 3 for very detailed analysis, and the relevance score, qualifying the validity of this classification at the level of the class considered.
- Step 1 1 All the programs thus generated with their descriptors are stored in the "gateway" 1 for broadcasting by the satellite network 5.
- Step 12 Only the descriptors defined above are disseminated.
- Step 13 Each receiver or user terminal receives the descriptors and extracts statistical data representative of the number and duration of the accesses already operated by the user on the class considered. It uses the pointer [a i; b], q] provided by the descriptor, pointer used to access the statistical table constructed by the receiver. This table may not have the three levels for the branch considered, which is the case in particular for branches little exploited by the user or at the start of learning, during the first operations of the device by the user; the evaluation is then based on lower level access statistics [a-êtbj, or even [aj, weighted by the difference in the level of the tree structure.
- the statistical value selected is the highest value, once weighted by the relevance score.
- the resulting weighted statistical value is called the score of the information element.
- Each score is representative of the interest that the user is likely to bring to the program carrying this element of information.
- a threshold S is determined in the receiver, expressing the storage capacity reserved in the receiver for the emissions received.
- the selection of emissions consists of retaining, in descending order of score, those whose sum of durations is part of the storage capacity, as defined by the threshold S.
- the receiver is ready to receive the programs.
- Step 14 The broadcasts are broadcast globally to all receivers.
- the satellite network 5 broadcasts, throughout the coverage area, each of the emissions produced by the production units.
- Step 15 Each receiver locally stores the broadcasts whose descriptors it has previously selected.
- Step 16 At the end of the broadcasting of all the programs, each receiver contains a personalized program determined by its user profile.
- the programs are sequenced for the consultation phase according to criteria which can be defined by the production units or by the user. according to their preferences: simply by domain and by decreasing score within the domain considered.
- Step 1 7 The user can then consult the programs stored locally in the receiver. Each program is presented to the user via the interface 19 shown. FIG. 7.
- next button allows you to go to the next program. If this key is pressed at the start of the transmission, the interface interprets the user's action as a rejection.
- the user can dynamically determine the programs he wishes to listen to. If he does not intervene in the progress of the program, he listens to all the programs classified in the order established in step 1 6.
- this information may not be available in the receiver, the corresponding program not having been selected during step 15 (frequent case at the beginning of operation of the system, the statistical table being only partially constituted).
- the receiver then sends a request to the "gateway" using the network.
- the gateway returns the requested transmission to this receiver instantly. This type of request takes place under the usual conditions of “pull” requests, regardless of the state of charge of the network.
- the invention in this case, does not avoid the transfer of information on the network during peak hours but limits their number, since this transfer only occurs if the user leaves the profile already set up by requesting broadcasts that do not 'have not been selected by the receiver.
- Step 18 While the user listens dynamically to the program, marking their choices by using the interface keys, the statistical table representative of the user's areas of interest is updated on the basis of the actions performed by the user.
- , q] is incremented if full access to the information element is made, without interruption; this value is maintained without change if the access was made with an interruption at the end of the consultation; the value is decremented if the access takes place from the start of the presentation of the information element (for example before the half-duration of the information element).
- the increment applied to the statistical value is a function of the level of detail associated with the information element: a complete consultation of a detailed element of information causes an incrementation of the statistical table more important than access to a presentation summary of the same subject. The degree of interest granted by the user to the subject is thus taken into account more precisely.
- Figures 3 to 5 show the degree of user interest by the thickness of each branch of the classification. The thicker the branch, the higher the user's interest in the corresponding information.
- Each incrementation or decrementation operation performed at a given level of the tree structure is naturally passed on to the entire branch up to the root of the tree structure.
- This confirmation can be returned to the "gateway" for processing and updating a note of relevance of the classifications assigned by the production units.
- the relevance rating of the classifications assigned by this production unit may be increased.
- the average relevance score of all the programs offered by the broadcasting company may constitute a quality criterion for its production units, and therefore a reliability criterion for potential users.
- a quality criterion for its production units and therefore a reliability criterion for potential users.
- This information is provided to the production units by the user returns defined above.
- the relevance scores assigned to the various pieces of information can be used as a tool for production units which can thus base their reputation on the relevance of the rankings they offer.
- the means of receiving information, assessing the degree of interest, storing information, and accessing information can be located on separate physical entities, the whole of these means being identified by the generic term receptor.
