Description

  The present invention relates generally to the field of personalizing services in a multimedia network, and more particularly to personalization based on information read from a code.

Background Personalization, interactivity, complex services and fixed-mobile convergence can be achieved in a variety of ways, but successful development of new services, And in order to achieve interoperability between technologies, the industry must follow open standards and open interface based methods. One of the most promising methods is to use the IP Multimedia Subsystem (IMS) framework. IMS was originally designed to enable multimedia services for 3G mobile terminals, but already handles access from public wireless local area networks (WLANs) and private networks. It is extended and continues to expand to platform-independent access for service delivery, including broadband fixed line access. IMS provides seamless roaming between mobile networks, public WLANs and private networks for a wide range of services. This service includes an interactive IP television (IPTV) device for playing games. The apparatus also includes a set top box, a multimedia player, and a digital camera.

  IMS's ability to deliver complex services allows TV, communications and Internet services to be seamlessly integrated to provide customers with a more convenient and engaging experience. IMS-based IPTV also inherits all IMS functions for service roaming, ie, using a common set-top box to link the IPTV experience with the user profile. Here, the apparatus to be used is not limited to this set-top box. Therefore, the IPTV service can be delivered to any device that conforms to the IMS interface and can be located within the IMS domain.

  Consumers are increasingly demanding to control TV services and delivered content anytime, anywhere and using any device. Personalization allows these consumers to customize TV and video on demand (VoD) packages according to their personal preferences and to give more and more control of channel content. The growing reputation of SMS-based voting and chat services in TV programs also shows increased business opportunities in the area of interactive services.

  IPTV implemented by IMS uses Session Initiation Protocol (SIP). This provides a unified control scheme that can be used to control all types of media sessions and application services. Support complex services and interactivity by incorporating different communication paradigms into the full multimedia user experience.

  The QR code (quick response code) is a matrix code or a two-dimensional bar code. This is generated for the purpose of deriving a code that makes it possible to decode its contents at high speed. Today, QR codes are used for inventory management in a wide variety of industries, and in Japan, two-dimensional barcodes are the most common type. Originally used to track parts in the car manufacturing industry, the introduction of QR codes as readout software for Japanese camera phones has led to a wide variety of new consumer applications. This is intended to relieve the user of troublesome data entry work for his mobile phone. QR codes that store addresses and URLs are becoming increasingly popular for magazines and advertisements in Japan. Adding QR codes to business cards has become very popular, which greatly simplifies the task of entering details of personal information of new acquaintances into the user's mobile phone address book. The consumer can acquire QP code data from the scanner using a capture program and a PC having an RS-232C interface.

  A user can build a personal profile by registering (bookmarking) products of interest. To bookmark a product, the user registers the code attached to the product by scanning a QR code or, optionally, by reading an RFID tag, color code or matrix code, etc. Memorize relevant product identities. Information related to the product can be stored in at least one of a database and a media player such as a network personal video recorder (NPVR). If such information includes personalized advertisements (individual advertisements), these can be verified on another occasion, for example on a TV, PC or mobile device, according to personal preferences.

  The method of delivering personalized advertisements, applied in many commercial systems available today, is based on the analysis of data entered by the user. Performing personalized advertising offers more value to both users and content providers. In existing technology, personalization of delivered content is based on past searches performed by the user or previously created messages. The fact that this information is stored can also be transparent to the user.

  Three-dimensional code systems that integrate digital components as well as analog components, both online and offline, are based on the use of color codes. In this system, the camera recognizes an indexing code that includes specific data. The block of color numbers and the matrix of analog data are digitized and processed by a dedicated server using a unique address registered for each of the codes. A typical color code interaction flow begins with authentication of a color code by a media player. Next, the number associated with the color code is transmitted to the server. The content or set of actions represented by the color code associated with the number is then sent to the media player for further processing.

  FIG. 1 shows an IMS-based IPTV architecture. This provides complex services and fixed network-mobile network aggregation. Although specified for IPTV services, a similar architecture can be used for other interactive services, which are accessed via a common IMS system. The architecture of FIG. 1 includes an IMS client environment 100, an IMS application server 101, a common IMS system 102, a transport layer 103, and a service distribution platform (SDP) 104. The service delivery platform provides a standardized set of support functions that can be shared across various service components.

  The major functional groups in the IMS client environment include an IPTV application 105, another application 106 such as a composite IMS service, a media client 107, and a SIP client 108.

  In the client environment, the IPTV application is responsible for all interaction between the IPTV service and the user on its media player 110. Examples of the media player 110 include a set top box / TV, a PC, and a cellular phone. Each media player is also a media client and a SIP client, which receives and decodes the video and audio streams that make up the digital TV signal. Here, the SIP client provides a control interface to the IMS core.

  Depending on the application, a media player is required to support dedicated hardware 111. The hardware 111 includes, for example, a camera, a scanner, or a microphone, which is connected to or incorporated in the media player.

  The IPTV application server 112, which is the center of the IPTV service, manages all IPTV dedicated functions that are not provided via the IMS interface, and is connected to the content provider 113. Each IPTV application server is connected to the IMS core and functions provided by the service distribution platform.

  The common IMS system includes an IMS core 114 comprising a call session control function (CSCF) 115 and a home subscriber server (HSS) 116, and an IMS enabler 117. The IMS core provides a control layer that controls services provided through fixed access networks and mobile access networks. The call session control function (CSCF), which is the central control point of IMS, provides a SIP routing service and performs authentication and authorization (AA). The HSS typically stores and provides user data in the IMS. Additional complexity may be included in additional databases. The IMS enablers that are most relevant to personalized TV services include presence and group management (PGM) and IMS messaging (IMSM).

  The Service Distribution Platform (SDP) provides various support functions that can be shared across different types of services. This support function includes a service provider support function such as a different charging model (charging) 118, an operation and maintenance (O & M) support function 119, and a content related support function such as an electronic service guide (ESG) 120. The ESG provides information about available services and includes an electronic program guide. This electronic program guide allows viewers to guide, search and select programs and content by date, title, channel and genre.

  The problem with existing solutions is that information gathering related to the user using the service is usually performed automatically without active user intervention. The user may not even be aware of this information collection that occurs during the execution of the service. This type of information collection does not allow the user to update and reuse the stored information, for example, for personalization purposes.

  Another problem is that while information gathering is limited for Internet searches and orders, other activities associated with human behavior are not recorded.

  In addition, it is not always appropriate that an immediate action is triggered by the information collected from the scanned code or the read RFID tag. This issue raises the question of how to enable updating of information related to an activity and to enable the activity to be stored and handled over time. Based on the personalized information that is present, the activity can be scheduled in various ways.

  Yet another problem with currently used systems is that personalization of individual users (individuals, for example) when members of various families are viewing content displayed on a shared device such as a TV. ) How to execute the dialogue. Today, this type of problem imposes the use of an active login process for each family member. Here, the family member can authorize himself / herself by inputting the remote PIN of the TV sharing the secret PIN code. This method does not provide a flexible way to update user preferences, nor does it perform user personalization related to individual user interactivity.

Summary The object of the present invention is directed to at least some of the problems described above. In particular, an object is to provide a personalization service to a user registered in a media player in a multimedia network such as IMS. This and other objectives are achieved by providing a method and application server for providing personalized service instructions based on information obtained from a code, such as a color code, QR code or RFID tag, for example. Is done.

  In the first embodiment, a media player, such as a mobile phone, is used to generate or update personal data stored in a preference database. The user can request a service from the second media player, where the personal data stored in the preference database is used for personalization.

  A first user who registers a first media player (UE A) with a first identity (ID_1) in a multimedia network uses a visual interface built into or connected to the first media player. Read the code. This code is decrypted by the media player, and a user preference message comprising the content of the code and at least one identity is generated by the media player application, which is configured to provide a personalized service according to the present invention To the designated application server. In the application server, one user preference data record for each identity of the user preference message is generated or, if it already exists, based on the content of the user preference message, that user preference message The data record is updated. A user who wants to activate the personalization service sends a request for the personalization service and a service request comprising a first identity, which is received at a second registered media player (UE B). In the application server, the user preference data record is obtained from the preference database. Based on the content of the service request and the content of the user preference data record, the application server requests a personalization message comprising personalization instructions at the service from the content database. The personalization message is sent to the second media player to perform the requested service.

  In a second embodiment, a first media player, eg, a mobile phone registered with a multimedia network with a first identity, interacts with a service displayed on a second media player, eg, a set top box / TV. Used for.

  A request for the personalization service is transmitted from the second media player (UE B) to the application server. In the case of unicast service delivery, the service-specific content associated with the requested service and the second user identity registering the second media player are encoded in the code and displayed on the second media player Forwarded to On the other hand, in the case of multicast service distribution, only content-specific data is transferred to the second media player. Here, a color code comprising content-specific data encoded with the second identity (group_ID) is presented at the second media player.

  The user can interact with the service by reading the code via the visual interface of the first media player (UE A). The content of the code is decrypted by the application, and a user preference message including the content of the code and the first identity (ID_1) in which the first media player is registered is generated and transferred to the application server. . This operation may be continued by additional interaction between the first media player and the application server. At the end of the dialogue, a user preference data record associated with and linked to the first identity and the second identity is generated. Alternatively, if it already exists, it is updated in the preference database.

  In the next step, a personalized feedback message is generated according to each of the user preference data record and the content associated with the service request. This personalized feedback message is forwarded to a first media player for invoking an application that is configured to perform the requested service. Depending on the service selected, the forwarded personalized feedback message may trigger one or more additional interactions between the first user's device and the application server, thereby providing a continuous interaction service. Are generated and forwarded to at least one of the first media player and the second media player.

  In the third embodiment, a first user with a first media player obtains access to presence information and a code, eg, a color code with a personal identity, of a second user with a second media player. By reading the code, the first user can update the personal group list and initiate a process for accessing the second user's presence information.

  The code comprising the second identity of the second media player registered in the multimedia network is read via the visual interface of the first media player registered in the multimedia network with the first identity. This code is decrypted at the first media player, a user preference message comprising first and second identities is generated indicating a request for presence information associated with the second media player and forwarded to the application server. The A group list is generated on the application server. Alternatively, if it already exists, it is updated in the user preference data record linked by the first identity.

  For security purposes, the first user requests authorization from the second media player to access the second user's presence information. Upon receiving a successful authorization, subscription to the requested presence information can be initiated and the second media player is added to the group list.

  The media player described herein may be any type of device configured to perform a personalization service in accordance with the above-described embodiments, including, for example, a mobile device, a PC There are set-top boxes connected to laptops, TVs or PDAs. The multimedia network for appropriately providing service personalization according to the above-described embodiments is any type of network having the function of processing the above-described signal transmission and reception and processing of the encoded information. This includes, for example, IP Multimedia System (IMS).

  The present invention also refers to an application server configured to provide a personalized multimedia service to a user who has registered at least one media player in the multimedia network.

  The application server comprises a communication means configured to communicate with a media player registered with the multimedia network via at least one identity. The communication means of the application server is also configured to communicate with a preference database comprising personalization content associated with a registered media player. Personalization content is stored in user preference data records, and identities link media players and records.

  The application server also includes a preference data control means, which stores a user preference data record when a user preference message comprising the code content and identity read by the media player is received at the media player. It is configured to generate or update. If a user preference data record linked by that identity does not already exist, a user preference data record is generated based on the content of the code. On the other hand, when the user preference data record is linked by the identity, the user preference data record is updated based on the content of the code.

  The application server is configured to communicate with one or more content providers comprising service specific data. A content provider may be defined as a content database with service specific instructions or as a dedicated server such as, for example, a presence server.

  The service control means of the application server is configured to generate the personalization instruction based on the service request received from the registered media player, the contents of the user preference data record, and the data acquired from the content provider. Is done. The service control means ultimately forwards the generated instructions to the media player, where the instructions can call a specific application.

  A preference database according to any of the above embodiments may be separate from or integrated with the application server to which it is connected.

DETAILED DESCRIPTION Briefly, the present invention is registered in a multimedia network based on code content (content) read using a code reading entity connected to or incorporated in a media player. A method and application server for providing a personalization service to a media player are provided.

  A common IMS-based system 200 that provides personalization services to a media player 201 according to one embodiment of the present invention is shown in FIG. Various types of media players, each with a SIP client (not shown), provide media player access to this common IMS system. A media player that is configured to interact with this common IMS system can be any electronic device that is adapted to assume SIP client functionality. These include, for example, mobile devices, set top boxes / TV (STB / TV), PCs or PDAs. Each media player can have one or more applications stored in the memory space, which are activated by personalization messages and sent from the application server in response to a service request. Each application may be activated as a result of communication between the media player and the application server, or may be dedicated for providing a service requested by the media player or content provider. A media player user who intends to personalize a service first reads a code that provides at least one of service-specific information and one or more identities, eg, via a code reading entity such as a scanner or camera. be able to. Each media player in the figure has means for reading and decoding a code 203 such as a QR code, a color code or an RFID tag.

  If the code is read, the media player establishes a connection with the IMS application server 204 via the CSCF of the IMS core. The IMS system shown in the figure comprises several IMS application servers, each configured to provide services to different types of media players. IMS application server 1 that provides services to mobile phones, IMS application server 2 that provides television services, IMS application server 3 that provides services configured for PCs, and IMS X, which is a default server, Service can be provided to media players that are specifically configured for these types. Through the IMS core, one of a plurality of IMS application servers (204, IMS AS1-X) responsible for the requested service is assigned. Here, together with the personal identity in which each media player is registered, the content of the code (content) is decrypted and transferred to each IMS application server. The IMS application server generates a user preference data record. This is stored in the preference database (207). This preference database may be located in the IMS core or content provider, for example, depending on the business model and O & D structure selected by each service provider. This preference data will be further described with reference to FIG. 6 below.

  The IMS application server has access to one or more content providers 206 with service-specific content used when setting up personalization instructions from a personalization service to a media player, such as, for example, an identified advertisement. Is provided. The content provider can also be accessed from the IMS application in response to receiving a request for a personalization service from the media player.

  The personalization service may be actively reextracted by the user of the media player, or may be activated by a predetermined state such as date and time. According to an embodiment of the present invention, a request for a service is sent from the media player as a SIP message, which comprises a feature tag that identifies an instruction associated with the requested service. If the feature tag is not added to the SIP message, a default command may be added to the body of the SIP message. In response to receiving a SIP message, including a feature tag, or a default instruction by an IMS application server configured to deliver the requested service, the IMS application server stores each Make a request for information from a user preference data record. Depending on the content of the service request and the content of the user preference data record, the relevant content sent from the content provider is collected and assembled to form a personalization message by the application in the IMS application server. The content obtained from the content provider can be in the form of an extensible markup language XML. The IMS application server adds a feature tag (FT1-FTX) corresponding to the service request to the XML. This message, here including the XML and feature tag, is forwarded to each media player for which the requested service is intended, and the personalization service is delivered to the media player.

  A strolling user can come across a product and find something of interest. Acquired with a QR code reader by reading a QR code with a product identity attached to the product using a QR code reader connected to or embedded in a media player registered in IMS The content is linked by the personal IMS identity with which the media player is registered and initiates a process for generating or updating the associated user preference data record. The information obtained from the above QR code can also be used to update the user preference data record by allowing the user preference data record to be changed according to the user behavior of the media player. . A media player can be shared by multiple users by linking each user to a specific user preference data record by their identity. Each user who wants to personalize the service can register a media player using his personal identity. This identity is linked to a user and a dedicated user preference data record, in which personalized data associated with that user is stored and updated.

  Since how the user preference read from the code is reflected in the content acquired from the content provider is not within the scope of the present invention, this process will not be described further.

  A signaling process showing an embodiment of the present invention when a user having a media player registered in the IMS network subscribes to an interactive personalization service will be described with reference to the signaling diagram of FIG. In the figure, a UE A300 that is a first media player such as a mobile terminal, for example, is SIP: user @ net. com, registered in a personal IMS identity (ID_1). In the first step 3: 1, the user reads the QR code 301 using the installed or connected cordiness 302. Here, in step 3: 2, the application decrypts the content of the QR code and generates a message comprising the content of the QR_code and ID_1. In UE A, the SIP MESSAGE method using QR_AD, which is a feature tag, to send the content of the QR code and ID_1 to the CSCF in step 3: 3 and to send it to the IMS application server 305 in step 3: 4 The SIP client 303 initiates communication with the IMS network (IMS core) via the CSCF 304 by generating a user preference message using. When the IMS application server receives the read information, a user preference data record linked by ID_1 is generated in the preference database 306 at step 3: 5. Alternatively, if it already exists, the relevant part of the user preference data record is updated according to the content of the received user preference message. In step 3: 6, this generation / update process is verified with a 200 OK message sent to the CSCF, and ends in UE A in step 3: 7.

  Another media player, UE B307, ie, a user who wants to receive a personalization service via STB / TV, depends on the information previously obtained from the QR code, and personalizes in UE B registered in IMS Can make a request for the service. As UE A, UE B has the same personal IMS identity, i.e. SIP: user @ net. By registering with com, each media player is linked to the same user preference data record. By forwarding this service request containing a unique instruction in the feature tag from the UE B to the IMS application server, the user instructs the IMS application server to deliver the personalized service to the UE B TV screen. . This instruction may, for example, instruct a user to request that a certain category of advertisements be received on the family's TV screen at a given opportunity. This message is configured as a SIP REGISTER message, and the requested service is specified by the attached feature tag TV_QR_AD. In step 3: 8, the message is sent to the IMS application server. The IMS application server that receives the service request from UE B makes a request for the user preference data record linked by personal ID_1 from the preference database in step 3: 9. Next, at step 3:10, the IMS application server makes a request from the content database 308 for a service specific instruction, such as an XML instruction, for example. The IMS application server that makes the request is configured with SIP MESSAGE that forms a personalization message including feature tags, TV_QR_AD, and XML description that is configured to follow the contents of each preference data record and the service request. At step 3:11, the personalization message is sent to the CSCF, and at step 3:12 it is forwarded to UE B. At UE B, the application interprets the received personalization message and the requested service is executed in a personalized way.

  In a home that owns a media player, ie STB / TV, registered with IMS via a family IMS identity (group IMS identity), several individuals, eg family members, share the same STB / TV can do. Also, each family member can have a unique media player, eg, a mobile phone. Each of these is registered with the IMS via a different unique personal IMS identity. In order to be able to provide a personalized service to multiple users at the same time, the content being displayed on a shared device, for example a TV screen, and also to individual user preferences stored in each user preference data record. In order to provide automatic generation / update of references and group user preferences, another embodiment is required. Such another embodiment will be described with reference to FIG.

  In the embodiment of FIG. 4, both a first media player 400, designated UE A, eg, a mobile phone, and a second media player 401, designated UE B, eg, STB / TV, are IMS. Each UE is registered with the group IMS identity, that is, SIP: group1 @ net. com to the user preference data record, and for UE A, the personal IMS identity, ie, SIP: user1 @ net. com to the user preference data record. Multiple additional media players can be registered with a personal IMS identity. That is, a personalization service can be provided to additional users. The user selects a service, eg, a TV program, by entering a command into UE B and forwarding it to the dedicated IMS application server 402 via CSCF 403.

  In the case of unicast service delivery, the group IMS identity to which UE B is registered includes a service request, a color code, which carries both content specific information and the group IMS identity. They are also generated by an IMS application server that can provide the service. The color code is transferred to UE B in the initial step 4: 1a and presented on the display of UE B.

  However, in the case of multicast service distribution status, only content-specific data is transmitted to UE B by the IMS application server for presentation on the TV screen. For multicast service delivery, the color code itself is generated by UE B's IPTV code generation application 404. Here, the group IMS identity to which UE B is registered is also encoded into a color code in step 4: 1b.

  The color code displayed on the TV screen includes content-specific information, that is, voting information. This is associated with each program on the display. In step 4: 2, the color code is registered by the code reading application 405 via a visual interface, for example a camera built in or connected to UE A. In step 4: 3, UE A's SIP client 406 decodes the color code and forms a user preference message. This includes code specific information and personal IMS identity ID_1. When the relationship (dialogue) with the record is terminated, the feature tag TV_CC_1 is added to the user preference message forming the SIP message. This is transferred to the CSCF in step 4: 4. In step 4: 5, this message is forwarded to the IMS application server. UE A's Graphic User Interface (GUI) also allows the user to interact with the IMS application server. This optional interaction will result in various messages being sent between UE A and the IMS application server, as shown in step 4: 6. Such interactions can introduce additional personalization of specific services. In the IMS application server, both personal and group IMS identities are extracted during the interaction. Depending on the outcome of the interaction, at step 4: 7, one or both relevant sections of the user preference records linked by each IMS identity can access each record from the preference database 407, Updated. If a preference data record linked by each identity does not already exist, such a record is generated in response to receiving a user preference message.

  In the IMS application server, at step 4: 8, one or both contents (contents) of the user preference data record launch the application and generate a personalization message. Here, related service-specific content is acquired from the content database 408. At step 4: 9, the personalization message is forwarded to the CSCF and at step 4:10 is forwarded to UE A. Here, the SIP client of UE A activates the application and executes the requested personalization service.

  As an option, the personalization service may also be involved with UE B registered in the group IMS identity. Such personalization message, finally forwarded to UE B at step 4:11, may comprise the same information that is sent to UE A or is associated with the group IMS identity. Depending on the content of the user preference data record, information according to another configuration can be provided. In UE B SIP, the UE B client 409 launches the application and performs the requested service according to the received personalization message.

  If a service related to a business transaction is selected from any of the registered media players, additional steps may be required. Such interaction can, for example, allow interconnection between each media player and a third party business application.

  In yet another embodiment, described with reference to FIG. 5, the content of the reading code, eg, color code 500, is sent to the first user A using the media player (UE A) 501 to the second media player ( Allows access to presence information of second user B using UE B) 502. Here, both media players are registered in the IMS. UE A has ID_A, for example, SIP: userA @ net. com, and UE B has ID_B, for example, SIP: userB @ net. com. The color code added to user B and comprising the user identity of user B, ID_A, is read by user A, for example, a code reader 503, which is a scanner, in a first step 5: 1. In step 5: 2, the read content is decoded by the decoding application stored in UE A, and ID_A is added to the color code. SIP MESSAGE FT: GLM_AS, a SIP message with a feature tag, is formed by UE A's SIP client 504. In step 5: 3, the SIP MESSAGE is transferred to the CSCF 405, and in step 5: 4, it is transferred to each IMS application server 406. In the IMS application server, the existing group list is stored by ID_A in a preference data record of a preference database (not shown) that exists separately from the IMS application server or integrated with the IMS application server, step 5: 5 is updated with data related to user B (ID_B). Next, at step 5: 6, the notification is sent to the CSCF as a 200 OK message and to the UE A at the next step 5: 7. Before user A can access user B's presence information, an authorization request must be approved by user B. Such authorization involving the SIP clients of UE A and UE B 507 is performed in step 5: 8. If authorized, user A will access user B's presence information by accessing presence server 508, as shown in step 5: 9.

  An IMS application server configured to provide a user with a personalized service according to an embodiment of the invention as defined in the claims will be described with reference to FIG.

  An IMS application server 600 configured to provide personalized multimedia services to users registered with the multimedia network (607), according to one embodiment described herein, is shown in FIG. It is. A user preference message comprising content obtained from the code and at least one identity is received by the communication means 601 of the IMS application server. The communication means communicates with one or more preference databases 603, where personalization content is stored in user preference data records. The identity with which the media player (606) is registered links a user preference message to each user preference data record. The communication means is also connected to one or more content databases from which service related information is set up to set up personalization instructions, i.e. personalization messages, used to personalize the service. You can search. Optionally, the IMS application server can access a dedicated server, such as, for example, a presence server, from which service specific information associated with each requested service can be retrieved.

  The contents of the user preference message are transferred to the preference data control means 602. The preference data control means 602 is configured to generate a user preference data record associated with and linked to the identity included in the user preference message. The content of the generated user preference data record is based on the content of the code. If preference data records already exist, the preference data control means is configured to update each record based on the contents of the code. The IMS application server has access to one or more preference databases 603, where user preference data records are stored. As indicated by the dashed rectangle, the preference database may be integrated into the IMS application server.

  The solid rectangle represents another alternative architecture, where the preference database is configured separately from the application server.

  In another embodiment, the preference data control means may be directly connected to the preference database rather than being connected via the communication means, as indicated by the broken line.

  According to one embodiment, the request for the personalized service received by the communication means 601 is forwarded to the service control means 604. The service control means 604 personalizes the requested service based on the service request, the contents of the user preference data linked by the identity of the request, and the data obtained from the connected content provider 605. It is configured. The content provider may be a content database with service-specific instructions or a dedicated server such as presence server A. The dedicated server can start the personalization service according to a predetermined rule. The predetermined rule may, for example, come when the day arrives, that is, when it becomes possible to operate in the same manner as a registered media player. A personalized instruction in the form of a personalized message is constructed by an application with a service control means by considering the content obtained from the service request, each preference data record, and the content from the content provider, and It is forwarded to a communication means for further distribution to the requesting media player.

  FIG. 7 shows the contents of the preference database 603. The one or more preference databases can be accessed from the IMS application server of the IMS network according to any embodiment proposed herein. If a preference message with content read from the code and a previously unknown identity (ID_1, ID_2) is received at the IMS application server, a user preference data record (700, 701) is generated by the IMS application server. . However, when a link to the user preference data record already exists, the related content of the user preference data record is updated in the preference database. Each user preference data record may include user preference data (702) indicated by a trigger rule set by a certain feature tag. This rule stored in the user preference data record may be triggered when a service request is received, or it may be applied to a media player registered in the user identity according to a predetermined rule such as a specific date and time. It may be automatically activated for distribution to a personalization service.

  Although the invention has been described with reference to illustrative embodiments, the description is intended only to illustrate the concepts of the invention and is to be construed as limiting the scope of the invention as defined by the claims. Should not be done.
