Abstract

Two service signals are transmitted) from a service server (ISP) through a first network (RD in such a way that user's terminal devices display personalised service data items. When service signals (SD) are filtered, a terminal device (DI) extracts common data items accessible for several terminal devices and a parameter type from a service signal identified by a stored identifier. An end address (@Fj) is determined by applying a stored parameter related to the parameter type to a pre-recorded or transmitted algorithm. Said end address is transmitted, through a second network (RP), to an (ISP) server which transmits a first personalised file (FPj) associated with the end address and bearing personalised data items (DPj) displayed with the common data items (DC) in the device.

Description

Customizing service in a terminal device

The present invention relates to the customization of service in user terminal devices.

More particularly, it relates to a service customization system whose common service signals intended for a large number of users pass from a service server to the terminal devices through a broadcast network and in which the server can communicate. interactively with the end devices through a point-to-point network.

There are several ways to distribute personalized information or services to a terminal device of a user: either through a point-to-point network or a broadcast network. The point-to-point network to which the invention also applies may be an interactive network where a user terminal transmits a request for services over a network channel to a responding service server providing service signals through the same channel. The point-to-point network has the advantage of providing on-demand services with an acknowledgment mechanism ensuring the good reception of a service signal selected by the destination device. The most well known applications that use this type of network are, for example, radiocommunication and the internet.

The customization of a service delivered by a point-to-point network is known. For example, a custom portal is implemented in a server service provider and offers a user to create his own web page by collecting links to several other websites. The end device of the user connects to the server via the point-to-point network and creates a user profile by, for example, entering his identity and interests which are then transmitted to the server in a secure manner. An identifier (login / password) is assigned to the user to identify him during the next connections to the server. Thus the user has an account at this service provider and chooses display modules proposed by the server that he wants to integrate and their layout on the page. The portal is personalized on the service provider 's server and is transmitted to the user through the point - to - point network. The significant cost of service customization that passes through the point-to-point network is due to the repetitive transmission of a large amount of data for each user of the network. In addition, access to information via the point-to-point network is slow and unavailable due to insufficient network bandwidth as soon as a large number of user devices are connected to the network at the same time.

The broadcast network to which the invention also applies may be a unidirectional network which transmits service signals to all the user devices connected to the network, some services being accessible only by a right of use. The services are therefore transmitted synchronously to the users who are authorized to access these services, without an acknowledgment mechanism. from a server. The broadcast network has the advantage of being addressed to many users. The most known applications are the broadcasting of television and / or broadcasting signals for example through a data broadcasting network of DVB (Digital Video Broadcasting) type, DAB (Digital Audio Broadcasting), DMB (Digital Multimedia Broadcasting), DTT (Digital Terrestrial Television), ISDB - T (Integrated Digital Broadcasting Services - Terrestrial), or MBMS (Mobile Broadcast Multicast Service), etc. In another example, a wireless local area network (WLAN) can be used as a point-to-point network (WIFI) and / or as a broadcast network (WIMAX). It is also known a service customization system proposed by service providers and whose services pass through the broadcast network from a service server to a user terminal. In this system, the broadcast service signals are accompanied by information associated with the services, this information being necessary for each terminal device to identify and filter the service signals in the broadcast stream according to a user profile including user parameters such as his identity and interests. These parameters are stored in a smart card inserted in a reader of the terminal. User interest information for each broadcast service is determined in the smart card based on the broadcast information associated with the service signals and the user parameters stored in the card. Thus the terminals transmit determined information to the service server to through a point-to-point network for selecting service signals broadcast in dependence of users' interests. Service customization is based solely on content filtering of broadcast service signals. The broadcast network does not transmit service on demand and has the disadvantage of broadcasting only the most used services. A user with an unusual focus, such as water skiing, can not access information related to this area of interest until it is broadcast on the network.

In another known service customization system, the end device of a user estimates the preferences of the user without the intervention of the latter, by learning according to the broadcast service signals which are selected by the user. The terminal device filters the broadcast service signals of interest to the user. This personalization system is still based on the content filtering of broadcast service signals and requires the broadcasting of numerous service signals in order to satisfy a large part of the users without however giving them access to service signals relating to service centers. unusual interest.

There is therefore a need for an inexpensive service personalization system but offering any user access to any service according to his or her centers of interest.

The aim of the invention is to overcome the aforementioned drawbacks by customizing service signals originating from a service server, directly in a terminal user device, and using both a service signal broadcast network and a point-to-point network.

To achieve this objective, a service personalization method in a terminal device receiving service signals broadcast through a first network from a server and respectively including data and service identifiers, the service signals being filtered by comparison between the service identifiers and an identifier stored in the device in a service signal identified by the stored identifier, is characterized in that it comprises the following steps: extraction of common data accessible to several terminal devices and of a type of service. parameter in the identified service signal, reading a parameter stored in the device and relating to the type of parameter, determining a final address by applying the read parameter to an algorithm, and transmitting a request including the final address through a second network to the server that transmits a first file Customized with the final address and with custom data, to record and / or display common data and custom data.

Although the algorithm may be pre-registered and common to the service signals, it may be retrieved from the identified service signal, or prerecorded in the device and designated by an identifier included in the identified service signal. Thus, according to the invention, the services in the terminal device are personalized directly in the terminal device, thanks to the personalized data dependent on the parameter read included in the profile of the user of the terminal device and transmitted by the server, the personalized data being able to be relating to an unusual focus of the user.

The common data of a service is transmitted through the first network called broadcast network, and the personalized data of said service are transmitted through the second network called point-to-point network. The invention is thus advantageous by reducing the interactivity and therefore the request-response exchanges through the point-to-point network, which reduces the load thereof and consequently the transmission cost.

According to one characteristic of the invention, after receiving the first personalized file that is transmitted with a second type of parameter, the method may comprise the following steps in the terminal device: reading a second parameter stored in the device and relating to the second parameter type, determining a second final address by applying the second parameter read to an algorithm, and transmitting a second request including the second final address through the second network to the server that transmits second personalized data associated with the first file customized through the second network to the terminal device.

According to another characteristic of the invention, the method may comprise a filtering of the signals of service distributed by comparison between the service identifiers and a second identifier retrieved from the first customized file in the terminal device to retrieve common data in a service signal identified by the second identifier.

According to yet another characteristic of the invention, the method may comprise, after receiving the first personalized file, a transmission of a request including a second final address extracted from the first personalized file through the second network to the server, said server transmitting to the server. terminal device a second personalized file associated with the second final address and having second personalized data.

The invention also relates to a service customization system comprising a terminal device and a server broadcasting service signals respectively including data and service identifiers to the terminal device through a first network, the service signals being filtered by comparison between the service identifiers and an identifier stored in the device into a service signal identified by the stored identifier. The terminal device comprises: means for storing the identifier and parameters associated with parameter types, means for extracting common data accessible to a plurality of terminal devices and a parameter type in the identified service signal, means for reading at least one stored parameter parameter type parameter, means for determining a final address by applying the read parameter to an algorithm, and means for transmitting a request including the final address through a second network to the server , the server transmitting personalized data in response to the final address to the terminal device. According to another embodiment of the terminal device, it comprises a terminal and a portable microcontroller recording medium, for example a smart card, in connection with the terminal. The terminal includes a first network interface connected to the first network for receiving the broadcast service signals and a second network interface connected to the second network. The recording medium includes the means for storing which further stores the extracted parameter type, the means for reading, the means for determining, and the means for transmitting a request through the second network interface, so as to immediately command or later in the terminal the means for displaying the common data and custom data.

Finally, the invention relates to a computer program capable of being implemented on a terminal device, said program comprising code instructions which, when the program is loaded and executed on said server, perform the steps according to the method of the invention.

Other features and advantages of the present invention will become more apparent to the Reading the following description of several preferred embodiments of the invention, given by way of nonlimiting examples, with reference to the corresponding appended drawings in which: - Figure 1 is a schematic block diagram of a service customization system according to a first embodiment of the invention;

- Figure 2 shows schematically an example of service data to customize; FIG. 3 is an algorithm of a service personalization method according to the invention;

FIGS. 4 and 5 are a sub-algorithm of the service personalization method according to the invention; and - Figure 6 is a block diagram of the service customization system according to a second embodiment of the invention.

The personalized services constructed by the invention are of any type.

For example, the home page of a supplier or company website is personalized for each user who has an account with the supplier or the company. The home page includes content common to all users of the website, including the date and general information on products and / or services offered by the supplier or the company, and personalized content for each user including including the name of the user and information or links to information relating to specificities of the user such as his interests, age, sex, habits, etc. Another example is a digital television network through which the user chooses a television program using an electronic program guide whose main page is displayed on the television screen of the television program. The user offers common television programs such as news feeds, and weather reports, and television magazines selected according to the user 's interests, which are not often requested by other users, such as a magazine on the Internet. a specific sport. According to another example, the broadcast network is a mobile cellular radio network of the MBMS or DVBH type (Digital Video Broadcasting-Handheld).

With reference to FIG. 1, a service customization system according to the invention comprises an ISP service server of a service provider communicating with several user communicating terminal devices DI, of which only one is represented in FIG. through an RD broadcast network and a point-to-point network RP.

For example, when the communicating user terminal device DI includes the functionalities of a smart television receiver, the broadcast network RD is for example a cable television distribution network and / or satellite, or DVB digital terrestrial television network. T (Digital Video Broadcasting-Terrestrial) broadcasting television program services. The point-to-point network RP comprises, for example, an access network such as a switched telephone network or a GSM or UMTS cellular radio network, and the Internet or a private network. The ISP server transmits broadcast service signals SD, for example in the form of packets or messages, including DSP data and service information IS characterizing and identifying a service broadcast through the broadcast network RD to the device DI. For example, the broadcast service signals are of the MPEG2 type and the service information IS is like SI / PSI tables (Service Information, Program Specifies Information). The IS information indicates for example the theme and / or type and / or a title or summary of the service developed in the data content, such as a particular sport, the local weather, a historical documentary, shows in a region, etc. The broadcast service signals SD with their service information IS are accessible by any device DI connected to the broadcast network RD. These broadcast service signals are filtered by the device DI as a function of the associated information IS that they contain and of user parameters PU relative to the user of the device DI and defining a profile of the user comprising the identity of the user. user and his / her centers of interest and preferences, to select and save service data to personalize DSP and designate associated FdP personalization files. The ISP server transmits at least one customized file FP according to the PU parameters of the user to the device DI through the point-to-point network RP in response to a request RQ including a final address @F and transmitted by the device DI .

The user terminal device DI comprises, according to the first embodiment of the invention, a processor P, an IRD broadcast network interface for receiving the broadcast service signals SD and the associated IS service information of the ISP server across the RD network, an IRP point-to-point network interface for transmitting RQ requests to the ISP server and receiving FP custom files from the server through the RP network, a MROM ROM, Flash or SRAM non - volatile memory for an operating system and programs specific to the invention, a MU memory including the user parameters PU associated with parameter types and defining the user profile. an MS memory for storing in particular DC common data accessible to several terminal devices and personalized data included respectively in the personalized service signals and the personalized files received, and a display E, such as a screen, for displaying said common data. combined with custom data. The display E can be external to the device and connected to it by a specific interface.

FIG. 2 shows an example of service data to be personalized DSP represented in the form of a page or several web pages and of personalization files FdPi, FdP ₂ and FdPβ received after filtering the broadcast services signals SD. The DSP data includes common fields ChC 1 and ChC ₂ which include common data DC ₁ and DC ₂ accessible to several terminal devices, and custom fields ChP 1, C ₁ P ₂ , C ₁ P 3 which include hyperlinks respectively calling the personalization files FdP 1, Fd ₂ and FdPβ. Each personalization file FdPi, FdP ₂ , FdPβ comprises a list including one or more types of parameter TPUi, TPU ₂ , TPU3, and may also include a initial address @Ii, @ Ï _{2 r} @ I3 and / or a call to a determination program A1, A2, A3 of a final address executed by the processor P of the device DI, or else the program of determination of address - even to load in the DI device after checking its integrity. Each type of TPU parameter indicates the PU parameter to be searched in the MU memory of the DI device such as the user 's name, address, age, sports preferences, etc. An initial address @I forms a "base" of address such as "http: // TV /" helping to determine a final address @F according to the PU parameters found in the memory MU. The final address @F in a request RQ makes it possible to determine the address of storage of personalized files FP in the server ISP, said files FP each corresponding to a personalized field ChP data to personalize DSP. To obtain these custom files, the DI transmits an RQ request including the @F final address to the ISP server through the point-to-point network.

In the example of a personalized service such as an electronic program guide, a presentation page of the guide includes common data such as the date, an announcement message and international news. The data to be customized in the guide are relative for example to the user 's name and to local news related to the user' s address and the sports events preferred by the user.

The service personalization method shown in FIG. 3 is executed by the processor P of the device DI and comprises steps E0 to E9. The step E0 consists in receiving, via the IRD broadcast network interface of the device DI, service signals SD including the service information IS, broadcast by the server ISP through the broadcast network RD.

In step E1, the processor filters the service signals SD to select service data to be personalized DSP associated with J personalization files FdPi to FdPj as previously described. The broadcast service signals SD are filtered by comparison between service identifiers included in the services service information IS and a broadcast identifier ID stored in the memory MU to extract and store service data to be personalized DSP of the service signal thus identified in the memory MS. The identifier ID relating to this service signal may be a PU parameter, or a data relating to a right of use of the service, or a data item resulting from a selection by the user, for example a request to view a guide. electronic program on the display of the DI device. The broadcast identifier ID more generally contains a broadcast network identifier and an identifier of the service signal broadcast by this broadcast network, which allows the device DI to select indifferently service signals broadcast by several broadcast networks. Then the processor P processes the service data to personalize registered DSPs.

In step E2, the processor P reads each common field ChC of the service data to be personalized DSP and writes in the memory MS the common data DC read in the common fields ChC. In this example, DSP data also includes J custom ChP fields. For each custom field

ChP _j , the index j being an integer between 1 and

J, the processor P executes a loop from step E3 to step E8 of the method as shown in FIG.

In step E3, the processor extracts from the field

ChP _j a call link pointing the associated personalization file and received FDP _j . In step E4, the processor reads, in the pointed file FdP _j, the parameter types TPU _j and reads in the memory MU the parameters PU _j relating to the types of parameter TPU _j . In step E5, the processor extracts the initial address @I _j from the personalization file FdP _j and determines a final address @F _j resulting from an application of the initial address extracted @I _j and read parameters PU _j to a respective algorithm A _j which can be pre-stored in the MROM memory of the DI device, or which can be extracted from the FdP file _j and loaded into the DI device, or which can be pre-registered in the DI device and designated by a identifier included in the FdP file _j . Alternatively, the algorithm A _j is an algorithm pre-recorded in the device and executed regardless of the broadcast service signal. Then the processor establishes in step E6 a request RQ _j including the final address @F _j , which is associated with a personalized file FP _j , and transmitted by the point-to-point IRP network interface of the device DI to ISP server through a point-to-point network RP channel. The FP _j file is addressed in a database of the ISP server according to the final address @F _j and includes custom data DP _j . In response to the request RQ _j , the ISP server transmits the personalized file FP _j to the device DI through the same transmission channel what constitutes the point-to-point network RP. The processor P of the device DI receives the file FP _j in step E7 by the point-to-point network interface

IRP of the device DI and stores the customized data DP _j of the file FP _j in the memory MS.

In step E8, if all custom fields

ChPi to ChPj in the DSP data have not been read, the processor executes a j + ^lth loop by reading in step E3 the j + ^lth custom field ChP _j + ₁ . Once all the ChPi to ChPj fields have been read and processed, the processor controls the display of the common data DC and the personalized data DPi to DPj extracted from the received files FPi to FPj and stored in the memory MS, on the display E of the DI device in step E9. The data DC and DPi to DPj are displayed in one or more pages according to locations defined in the respective fields ChC and ChPi to ChPj of the DSP service data thus personalized. As a variant, in step E9, the common and personalized data are stored for later display either on the screen E of the device DI or in another device of the user via a recording medium removable .

At the request of the user, the processor can subsequently retrieve the common data DC and the personalized data DP without necessarily accessing the server ISP by one of the two networks RD and RP, thanks to the memory MS which recorded said data. This has the advantage on the one hand of viewing the data of the selected service without any connection to the two networks and on the other hand of decreasing the access time to the personalized data DP. Steps E0 to E8 can be executed in the background without the intervention of the user.

Figures 4 and 5 show Sl sub-steps S12 relating to the execution of the step E7 when the custom file FP _j, referred to hereinafter as the first personalized file REIT description _jf received by the device DI through RP network, includes first custom data DPI _j and K customizable fields ChPIi to ChPlK- In this case, in response to the request RQ _j , the device DI receives the sub-step Sl the file FPI _j and R customization files FdP2χ at FdP2 _R , the number R of personalization files FdP2 being different, or possibly equal to the number K of custom fields included in the file FPI _j . In the substep Sl the processor P stores the first custom data DPI _j in the memory MS. According to the data in each field ChP1 of the file FPI _j , the index k being an integer between 1 and K, the processor executes either the substeps S2 to S6, or the substeps S7 and S8, or substeps S9 to SI1.

In the substep S2, the processor P checks whether the field ChP1 contains a call link pointing to a personalization file received FdP2 _r associated with the field ChP1, the index r being an integer between 1 and R. The processor P executes substeps S3 to S6 which are identical to steps E4 to E7 previously described, as shown in FIG. 4. In substep S3, the processor reads in the pointed file FPD2 _r associated with the field ChP1 parameter types TPU2 _r and reads in the memory MU the parameters PU _r relating to the parameter types TPU2 _r . In substep S4, the processor retrieves the address initial @ l2 _r of the personalization file FdP2 _r and the respective algorithm A2 _r or an identifier thereof and determines a final address @F _k resulting from an application of the initial address extracted @ l2 _r and read parameters PU _r to an algorithm A2 _r . Then in the substep S5, the processor establishes a second request RQ _k comprising the final address @F _k which is associated with a second personalized file FP2 _k including second personalized data DP2] _C. The IRP point-to-point network interface of the DI device transmits the second request RQ _k to the ISP server through the point-to-point network RP. In response to the second request RQ _k, the ISP server transmits the personalized file FP2 _k associated with the address @ F _k to the device DI through the point-to-point network RP. The processor P of the device DI receives the file FP2 _k in the substep S6 by the point-to-point IRP network interface of the device DI and stores the second custom data DP2 _k of the file FP2 _k in the memory MS.

Another field ChPl of the file FPI _j may also comprise a call link for pointing a second personalization file FdP2χ to FdP2 _R by incrementing S61 of the index r. Similarly, as indicated in substep S12, if FP2 _k also includes custom fields, processor P iteratively executes substeps S2 through S12. If in sub-step S2, the field ChPI _k does not contain a call link relating to an FdP2 personalization file, the processor proceeds to substep S7. If the field ChPI _k contains a second diffusion identifier ID2 _k distinct from the first identifier ID present in step E1 and relating to a service signal broadcast by the ISP server through the broadcast network RD, the processor P filters the broadcast service signals SD received by the IRD broadcast network interface of the device DI to record second common data DC2 _k relating to the second broadcast identifier ID2 _k in the memory MS, in the substep S8. The processor then executes substep S12. Using the example of the electronic program guide, the second broadcast identifier is an indicator of a national football match that is of interest to a large number of users and is then broadcast through the R & D broadcast network. If in sub-step S7 the field ChIP _k does not contain any second broadcast identifier ID2 _k , the processor executes substep S9 to extract a final address @URL included in the field ChIP _k . Following the example of the electronic program guide, the @URL address is a link to a video clip representing a sport not broadcast by the RD broadcast network but accessible by the point-to-point network RP, because interesting a minority of users. At the substep SlO the processor establishes and transmits a request RQ _k through the point-to-point IRP network interface of the DI device to the ISP server through the point-to-point network RP. The request RQ _k comprises the address @URL which is associated with a second personalized file FP2 _k including second personalized data DP2 _k and stored in the database of the server ISP. In response to this request RQ _k , the ISP server transmits the personalized file FP2 _k to the device DI through the point-to-point network RP. The processor P of the device DI receives the file FP2 _k at the substep SI1 through the interface of IR point-to-point network of the DI device and stores the second custom data DP2] _C FP2] _C file in the memory MS. Referring to the previous example, the custom data DP2] _C is the video clip.

In the substep S12, the processor P verifies that all the custom fields ChIPi to ChlPκ of the file FPI _j have been read. Otherwise the processor executes a k + l ^th loop S2 to S12 by reading in step S2 k + l ^th custom field HPLC _k + i - Once all Chipi fields ChlPκ FPI _j file were read and processed, the processor executes steps E8 and E9 as described with reference to FIG.
