Description:
TECHNICAL FIELD 
       [0001]    Embodiments of the present invention relate to a system and method for providing hint information of an interactive broadcast program to a user satisfying a predetermined condition. 
       RELATED ART 
       [0002]    Not to mention of the recent fusion between broadcasting and communication, the distributions of various terminals, such as a smart television (TV), a smartphone, and an Internet protocol (IP) TV, have brought a transition from an existing uni-directional TV environment to a bi-directional participative environment capable of interacting with users. 
         [0003]    To trigger a user participation, an interactive broadcast service producing method according to a related art has adapted a separate individual exclusive mobile application or a short message service mobile oriented (SMS-MO) system to fit for a broadcasting environment. However, in the case of using the exclusive application, a corresponding application is to be installed for the user participation. In the case of using the SMS-MO system, a user needs to pay a communication company for separate communication expenses. Also, due to the diversification of channels allowing users to participate in a broadcast program, the existing method has some constraints in terms of expandability and instantaneity in the case of using various channels to optimize the user participation for each individual program. 
         [0004]    Further, in the case of a program produced in series, program copyright information of each episode is managed and used in an individual document form. That is, since writers or producers (PDs) are managing information of each episode in an individual document form, the management efficiency may be degraded. In addition, issues such as duplicity or loss of a document are highly likely to arise and formatting information for each episode may be inconvenient. 
         [0005]    In an interactive program service, a means capable of aggressively using an advertisement is insufficient. In addition, in the case of thoughtlessly providing a mid-program advertisement, many users participating in a program may leave the program and there is no particular method capable of guaranteeing (lock-in) program participants during mid-program advertisement hours. In particular, a broadcast program unilaterally provides advertisement information scheduled in advance and thus, there are some constraints in providing a participant customized advertisement.

     BEST MODE 
       [0037]    Hereinafter, embodiments of the present invention will be described. 
         [0038]    An interactive broadcast service has been evolved to a level at which a participation and a response through direct interaction with individual programs are allowed, beyond a service level for simply verifying information associated with a program or news. During such a process, various types of broadcasting genres will be developed. In particular, a reference program that draws a high participation of users is to be distributed in an individual program format and grown into the global format business. 
         [0039]    Accordingly, the present invention proposes a technology capable of providing various communication functions required for an interactive broadcast service, together with a production tool directly executable in a real broadcasting environment in order to achieve a user participative interactive broadcast service. 
         [0040]    In the present specification, the term “broadcast program” may inclusively indicate multimedia contents produced to enable any type of interactivities, for example, a user participation such as a question (quiz), a survey, a vote, and an application, and a user record such as a bookmark and an annotation. The term “producer” may indicate a target that plans and produces an interactive broadcast program, such as a writer or a PD in broadcasting. The term “manager” may indicate a target that is in charge of a system setting and operation to provide an interactive broadcast program. Also, the term “user” or “participant” may indicate a target that directly participates in a broadcast program as a viewer viewing the broadcast program. 
         [0041]    Embodiments of the present invention may be applied to all the systems based on a user participative interactive service, such as an e-Learning system, not to mention of a broadcast system of a TV environment. 
         [0042]    Hereinafter, a program enabler service system and a program enabler service method for providing an interactive service of a broadcast program will be described based on an example of a broadcast program in which a question is given during a broadcast and a user participates. 
         [0043]      FIG. 1  is a block diagram illustrating a configuration of a program enabler service system according to an embodiment of the present invention. 
         [0044]    Referring to  FIG. 1 , the program enabler service system may include a program creator  110  for creating a broadcast program, a program executor  120  for executing the broadcast program created by the program creator  110 , and a service connector  130  for connecting a communication service for interacting with the broadcast program executed by the program executor  120 . 
         [0045]    As a system available by a producer at the planning stage to produce a broadcast program, the program creator  110  may support a tool (iFormat editor) of providing a production function of designing and scripting parts allowing a user participation in the broadcast program using a predefined enabler and a visual tool, and directly executing the scripted parts in a real broadcasting environment. In the present embodiment, as a program authoring tool required at the stage of producing the broadcast program, a function capable of inputting basic information required for the broadcast program, a function capable of selecting a broadcast participation channel by adding various service enablers, and a function capable of easily editing information for each episode of the broadcast program, converting the information to a script format, and launching the converted information in a real broadcasting environment may be provided. 
         [0046]    As an enabler system for executing the broadcast program, the program executor  120  may read broadcast program information produced using the tool, may provide an interactive participation means required for the corresponding broadcast program in association with various communication channels such as various legacy systems and/or social services, may provide statistical information of the corresponding broadcast program, and may support a function such as a monitoring tool and a user response management for progress of the broadcast program. 
         [0047]    The service connector  130  may support an adaptor function capable of easily and conveniently associating various communication channels with the broadcast program. In the present embodiment, various communication functions required to service a broadcast program may be provided as a technology for easy and convenient interaction between various communication channels and the broadcast program. 
         [0048]    Hereinafter, a program creator  210 , a program executor  220 , and a service connector  230  will be described with reference to  FIG. 2 . 
         [0049]    The program creator  210  is configured to provide an environment (iProgram Creation Environment) for authoring a broadcast program and may include an input module (iFormat Editor)  211  and an authoring module (iProgram Designer)  212 . 
         [0050]    The input module  221 , as a tool used by a writer or a PD in broadcasting to plan an interactive program, may indicate a tool for registering/correcting/deleting a program information input and participation method, a question, and the like. 
         [0051]    The authoring module  212  may author the broadcast program in a format executable in the program executor  220  by scripting data input to the input module  211  through various types of modules (iProgram Script creator, iProgram Script Validator, iProgram Execution Language) for scripting the broadcast program. 
         [0052]      FIGS. 3 through 13  illustrate editor screens provided from the input module  211 . 
         [0053]    Referring to  FIG. 3 , the input module  211  may provide a log-in screen  300  for allowing an access of a producer having a right to input and correct information of a broadcast program. In this instance, the log-in screen  300  is configured to receive an identifier (ID)  301  and a password (PW)  302 . When an editor right is different for each type of producer such as a PD and a writer in broadcasting, the log-in screen  300  may receive an ID/PW together with a producer type  303 . 
         [0054]    Referring to  FIG. 4 , the input module  211  may provide an editor start screen  400  to a producer connected through a log-in procedure. The producer may select or input a program  401  and an episode  402  that are to be authored through the editor start screen  400 . In addition, the producer may input episode information (comment)  403 , cast information  404 , an air time  405 , and a program ID  406 . Further, for communication with a user, a service enabler  407 , such as a mobile instant messenger (IM), Twitter, and Facebook, which is to interact with the broadcast program, may be selected on the editor start screen  400 . Here, the program ID  406  is an ID of a program manager. For example, when a mobile IM is used as a communication channel with a user, the program manager needs to be regarded as a single buddy ID. A buddy ID for a corresponding program needs to be created for a question and an answer through the mobile IM. The editor start screen  400  may be configured using a direct input method of a producer and a selection method from a predetermined item. 
         [0055]    Referring to  FIG. 5 , the input module  211  may provide an initial setting screen  500  for inputting basic information required for the broadcast program. The estimated number of participants  501  in the broadcast program, a reward (for example, money and gifts)  502 , a winner (the number of persons or conditions)  503 , and other options associated with a winner  504  may be set on the initial setting screen  500 . The initial setting screen  500  may be configured using a direct input method of a producer and a selection method from a predetermined item. 
         [0056]    Referring to  FIG. 6 , the input module  211  may provide a question screen  600  for inputting a question during a broadcast. Here, the question screen  600  may include contents  601  of a question, a consultation  602  associated with the question, a type  603  of the question, and examples  604  of a multiple-choice question. Also, the question screen  600  may include a “save” menu  605  for storing a question input by a producer, a “reward” menu  606  for setting a reward for the question, and an “option” menu  607  for setting an option associated with the question. 
         [0057]      FIG. 7  illustrates a reward setting screen  700  displayed in response to the “reward” menu  606  on the question screen  600 . A producer may set a reward to be provided to a user (for example, a correct answerer and a user having viewed an advertisement) matching a predetermined condition through the reward setting screen  700 . In this instance, the reward may be individually set for each question. 
         [0058]      FIG. 8  illustrates an option setting screen  800  displayed in response to the “option” menu  607 . A producer may individually register various options, such as a photo (still image, a video, etc.), advertisements (ads), and a condition in association with each question, through the option setting screen  800 . Also, the option setting screen  800  may provide a function of giving a hint to participants matching a predetermined condition and a function of setting whether a retry opportunity is available, as an individual question option. 
         [0059]    Referring to  FIG. 8 , the producer may set a hint to be given to participants by setting a hint text, a target to receive a hint, a hinting method, and a hint query. A method of selecting a target to receive a hint may use a method designated by a program producer among a variety of methods such as a method of responding to a predetermined query, a method of responding to a predetermined advertisement, a method of responding to predetermined content (video or a voice file), a method using a location matching condition (for example, a user located at a predetermined location and a user having checked in at a predetermined location). Also, when the target to receive a hint is determined, a method of giving a hint may use a method of giving a hint to the corresponding target in an attached file format or a message format through a mobile IM. Here, a method of responding to a predetermined advertisement may include a method of giving a hint to users adding an advertisement buddy (that is, an ID of an advertiser) to a buddy list or inviting the advertisement buddy to a chatting room, a method of giving a hint to users executing advertisement content through an advertisement push, and the like. For example, in a case in which a producer selects a method of “providing through Ad buddy” as a hinting method  802  to a corresponding question and inputs a hint text  801  and an advertisement buddy ID  803  in the case of setting a hint option through an option setting screen  800 , the hint text  801  may be limitedly provided to users setting the advertisement buddy ID  803  as a buddy when giving the corresponding question during a broadcast. Meanwhile, when the producer selects a method of “providing through an advertisement push” as the hinting method  802  and inputs a link address of advertisement content, a hint text may be provided to users having connected to advertisement content through an advertisement push when giving the corresponding question. In the case of a method of responding to a predetermined query, the producer may set a hint giving option by inputting a query that is a correct answer of a hint giving question, together with a query message for giving a hint, that is, a hint giving question. 
         [0060]    The producer may set the hint giving option so that a retry opportunity may be assigned to participants matching a predetermined condition among users having submitted incorrect answers to a given question. Referring to  FIG. 9 , the producer may set a retry opportunity to be assigned to a participant having made an answer corresponding to a predetermined condition by setting a means (for example, an advertisement) for assigning a retry opportunity, a method of displaying the means, and a response time to the means. Here, similarly, the retry opportunity may also be assigned using a method of assigning a retry opportunity to users adding an advertisement buddy, a method of assigning a retry opportunity to users having executed advertisement content through an advertisement push, and the like. Also, an advertisement for provide the retry opportunity may be provided when a user response to a question is an incorrect answer and an amount of time remaining by a question solution end time is greater than an advertisement running time or an estimated minimum response time. For example, in a case in which the producer sets “push-image” as an advertisement exposure method  902  and registers an advertisement image on an advertisement registration menu  901  through an option setting screen  900 , the retry opportunity may be provided to a user having submitted an incorrect answer to a question by pushing the advertisement image registered at the event of setting an option, when the user executes the corresponding advertisement image. Here, in a case in which the producer inputs an estimated minimum response time  903  through the option setting screen  900 , an advertisement for assigning a retry opportunity may be provided only when an amount of time remaining by the question solution end time is greater than the input estimated minimum response time  903  at a point in time at which the user has submitted the incorrect answer. 
         [0061]      FIG. 10  illustrates an example of a question screen  1000  input by a producer. Referring to  FIG. 10 , “why the specialty &lt;buckwheat noodles&gt; of Chuncheon is buckwheat noodles” in contents of a question  1001 , “Chuncheon buckwheat noodles experience museum” as a consultation  1002  thereto, an “alternative” type as a question type  1003 , and two examples as examples of the alternative  1004  may be displayed on the question screen  100  based on an input and settings of the producer. In addition, an option status  1005  of a question set by the producer may also be displayed on the question screen  1000  based on a setting of the producer. 
         [0062]    Questions to be given in a broadcast program through editor screens described with reference to  FIGS. 3 through 10  may be individually created. In this instance, a list of questions created by the producer may be sequentially aligned and thereby displayed on one side of a question screen. 
         [0063]    Referring to  FIG. 11 , when creation and setting of questions to be given for a predetermined episode of a broadcast program are completed, the input module  211  may provide a process creation screen  1100  for setting a question solving process. In this instance, the process creation screen  1100  may also provide a list  1101  of questions created by a producer and a screen  1102  for adding a question to a list for each round. For example, referring to  FIG. 12 , the producer may selectively set a question to be given for each round by selecting a question to add to each round from a list  1201  of questions and dragging the selected question to a question addition screen  1202 . 
         [0064]    Further, the process creation screen  1100  may provide a function of adding two or more questions as a question to be given at one round and a function of setting detailed conditions for connection between questions. That is, two or more questions of different conditions based on a previously given question may be set as subsequent questions to be given (interactive question). Referring to  FIG. 13 , in an example in which questions A and B are set as a question  1302  to be subsequently given after a first question  1301  is given at a first round, a condition  1303  may also be set that if a correct answer rate of a first question is 30% or less, the question A is given as a subsequent question, and if the correct answer rate of the first question exceeds 30%, the question B is given as the subsequent question. 
         [0065]    According to the above configuration, the input module  211  may provide a function of inputting basic information (episode number, broadcast start/end time) of a broadcast program and a function of selecting a service enabler to interact with the broadcast program through the aforementioned editor screen, and may also provide the overall function of inputting an interactive object (for example, a quiz, a survey, an application, and a vote) allowing a user to participate in the broadcast program and creating a participation process for the corresponding interactive object. 
         [0066]    Referring again to  FIG. 2 , the program executor  220  serves to provide an environment (iProgram Runtime Environment) for executing a broadcast program authored by the producer. Referring to  FIG. 2 , the program executor  220  may include a portal module (iProgram Studio Portal)  221 , a management module (iProgram Lifecycle Manager)  222 , an execution engine (iProgram Execution Engine)  223 , a recording module (iProgram Logger)  224 , a monitor module (iProgram Monitor)  225 , a registration module (iProgram UDDI Repository)  226 , a bus module (iProgram Bus)  227 , and a storage module (iProgram Database)  228 . 
         [0067]    The portal module  221 , as a web-based portal system for using an enabler system, indicates a system accessible by registering a user ID at the event of launching an individual service enabler and basically used by a program manager. The portal module  221 , as a service enabler for communication with a user, may interact with a mobile IM, Twitter, and Facebook. 
         [0068]    The management module  222  may provide a function of managing a service lifecycle of an individual service enabler and a function of launching and closing a service to fit for a broadcasting environment in interaction with the broadcast program.

         [0082]      FIG. 18  illustrates a configuration of a program enabler service system including a mobile IM enabler  1840  as an example of an interactive service enabler. A description related to constituent elements described above with reference to  FIG. 2  among constituent elements of the program enabler service system of  FIG. 18  will be omitted. 
         [0083]    The present embodiment may apply the mobile IM enabler  1840  for a user participative interactive service with respect to a broadcast program, and may use an advertisement as a means for providing additional information and an additional service associated with the broadcast program to a user through the mobile IM enabler  1840 . Here, the advertisement, as the means for providing additional information or an additional service, may be displayed to the user in a variety of forms such as a related video, image, text, and a hyperlink. 
         [0084]    A service connector  1830  may be connected to a mobile IM service platform  1850  and/or an advertisement server  1870  through a legacy adaptor. That is, the legacy adaptor may provide an adaptor function through an interaction with a mobile IM platform service provider and an adaptor function through an interaction with an advertisement database. 
         [0085]    The mobile IM enabler  1840  may be included as an internal configuration of a program executor  1820  or may be configured as a separate system to interact with the program executor  1820 . In the present embodiment, the mobile IM enabler  1840  may provide a communication channel with a user participating in a broadcast program, and may serve to open a chatting room for the broadcast program through a buddy setting with a user that is to participate in the broadcast program. Further, the mobile IM enabler  1840  may serve to provide a variety of additional information or services associated with the broadcast program through a mobile IM by associating the variety of additional information or services with an advertisement. 
         [0086]    Referring to  FIG. 18 , the mobile IM enabler  1840  may include an interface module (Web-based GUI MO)  1841 , a message control module (Message Control Function)  1842 , a statistics module (Real-time Monitoring Function)  1843 , a buddy management module (Buddy List Control Function)  1844 , a chatting room control module (Chatting Room Control Function)  1845 , and a response recording module (Score Recording Function)  1846 . 
         [0087]    The interface module  1841  provides a function capable of verifying information of users (buddies) participating in a program, a message reception/send status, and a response (correct answer/incorrect answer) of a user in a web-based GUI form. 
         [0088]    The message control module  1842  may provide a function of triggering the participation intent of a user through a character string based filtering (message matching) and a function of determining whether a response of a participant is a correct answer or an incorrect answer. Also, the message control module  1842  may provide a function of sending a predetermined message to a user (buddy) through interaction message recognition on a program script. Here, a delimiter that enables an authoring module  1812  of the program creator  1810  to identify a type (for example, a question, a hint of the question, etc.) of a corresponding message needs to be created. For example, the message control module  1842  may read a delimiter capable of identifying whether a type of a message to send to a user is a question or a hint, and may indicate the read delimiter on the message displayed through a mobile IM application installed in a terminal of the user. Further, in the case of a message associated with an advertisement, the message control module  1842  may provide a connection function through a hyperlink within the message. When an advertisement is set as a means for providing a hint or a retry opportunity to a given question, the message control module  1842  may include link information of the corresponding advertisement in a message to be transferred to the user. All the responses (that is, a playback, a connection, etc.) to the message associated with the advertisement pass through the message control module  1842  on the mobile IM enabler  1840  to verify the accuracy of advertisement execution and whether to execute the advertisement. 
         [0089]    The statistics module  1843  may provide a statistical function such as the number of users participating in a program, a participation rate for each question, and a correct/incorrect answer rate in real time. 
         [0090]    The buddy management module  1844  may provide a function of managing a list of buddies having set a relationship based on an ID on a messenger created by a manager with respect to the broadcast program. In this instance, when a user authentication function is required to set a relationship with a user, the buddy management module  1844  may interact with an authentication system through a legacy SCP or a legacy adaptor. The buddy management module  1844  may provide a function of managing messenger IDs of advertisers providing advertisement contents, that is, an advertisement buddy list. In the present embodiment, advertisers may indicate entities that provide advertisement contents such as an indirect advertisement of a broadcast program, and may register their messenger IDs in association with a corresponding advertisement when registering advertisements. Accordingly, the buddy management module  1844  may support a function of inviting an advertisement buddy to a chatting room participated in by the user, a function of adding an advertisement buddy to a buddy list of the user, and the like, through interaction with the message control module  1842 . 
         [0091]    The chatting room control module  1845  may provide a function of opening a program chatting room for reading chatting room creation information associated with the broadcast program and then verifying whether a user included in a buddy list participates in a corresponding episode of the broadcast program. Here, the chatting room control module  1845  may individually open a program chatting room for each episode of the broadcast program. In the case of using a character string based filtering method, the chatting room control module  1845  may recognize an input of a predetermined character string among character strings input from the user through the program chatting room and may verify the participation intent of the user. Here, the predetermined character string to be used to verify the participation intent of the user may be registered in advance to the message control module  1842  by the program manager. 
         [0092]    The response recording module  1846  may provide a function of recording a success/failure (correct answer/incorrect answer) of a response to a question for each user ID included in a buddy list of a manager ID. Also, the response recording module  1846  may provide a function of storing a hint answer received from a user to be distinguished from a question answer based on a separate flag as expressed by the following Table 1. The response recording module  1846  may provide a function of recording the number of executions and responses (for example, the number of invitations, the number of buddy additions, the number of playbacks, and the number of connections) with respect to the advertisement. Information recorded in the response recording module  1846  may be used to calculate statistical information in the statistics module  1843 .

         [0093]    When providing an individual question, the mobile IM enabler  1840  constructed as above may determine whether to give a hint for a corresponding question based on a hint input status, and may employ a character string matching method as an example of the determining method. Also, when giving an individual question, the mobile IM enabler  1840  may determine whether to give a hint to a corresponding question or whether to assign a retry opportunity to an incorrect answerer based on a user response. As an example of the determination method, an advertisement buddy adding method, an advertisement buddy inviting method, and an advertisement push method, and the like, may be employed. 
         [0094]    A mobile IM application  1860  installed in a terminal of a user may include a user management module (Chatting UI Manager)  1861 . In this instance, when an ID of a conversation partner requested by the user to create a chatting room is not a personal ID, for example, in the case of a special service such as an interactive broadcast program, the UI management module  1861  may provide a function of visually expressing participation information about the corresponding program by changing a chatting UI. To this end, the UI management module  1861  supports a function capable of changing a chatting room of a program participated in by the user using a background image or a window UI set by the program manager. Also, the UI management module  1861  may provide a UI for inputting an “answer” to a question and a separate UI for inputting a “response” to a hint, as UIs for a user input in a program chatting room. That is, the UI management module  1861  may activate the UI for inputting an “answer” to a question and in this instance, may verify whether a hint is given for the question. In this instance, when the question is a hint giving question, the UI management module  1861  may also activate the UI for inputting a “response” to a hint. The UI management module  1861  may support a function of inactivating a hint message when a predetermined period of time is elapsed after receiving the hint message based on a characteristic of the hint and a function of providing a hint message one time in a marquee form, as an additional function associated with a hint UI. 
         [0095]    Further, the mobile IM application  1860  may execute advertisement content provided from the advertisement server  1870  through link information included in a received message. The UI management module  1861  may provide a communication function for an advertisement included in the received message using a variety of methods. The UI management module  1861  may support a function of inviting an advertisement buddy to a program chatting room or adding the advertisement buddy to a buddy list as a communication method for the advertisement, and may also support a function such as a function of activating a hypertext of an advertisement included in the received message, a function of outputting an image in a chatting room, a function of changing to a background image of the chatting room, a function of playing back a video in the chatting room, and a function of playing back a video through interaction with a separate application. 
         [0096]    Finally, the advertisement server  1870 , as an advertisement database system to store and maintain advertisement contents, may include an advertisement monitor module  1871  and an advertisement media server  1872 . Here, the advertisement media server  1872  may indicate a media server to provide advertisement content to a user by way of the mobile IM application  1860 , and the advertisement monitor module  1871  may serve to record a user response to an advertisement provided through the mobile IM, and to analyze the advertisement execution effect based thereon. As described above, the advertisement server  1870  performs the functionality of an advertisement platform, such as registering an advertisement of an advertiser, determining an advertisement inventory, providing an advertisement to a publisher (that is, a user terminal), charge according to displaying of an advertisement, distributing advertisement revenues to the publisher, and the like. 
         [0097]    According to the present embodiment constructed as above, a mobile IM enabler is included as a communication channel for a broadcast program and thus, it is possible to support a user participation in a convenient environment by providing various communication functions required for the corresponding broadcast program through a mobile IM service. In addition, in the present embodiment, it is possible to use an advertisement as a means for providing an additional information or service associated with the broadcast program, and to give a hint of a question in the broadcast program or to assign a retry opportunity to a user having submitted an incorrect answer to the question using an advertisement buddy adding method, an advertisement buddy inviting method, an advertisement push method, and the like, through the mobile IM enabler  1840 . 
         [0098]    Further, irrespective of additional information or an additional service associated with a given question, the program enabler service system may configure an advertisement model to directly provide a user with a mid-program advertisement or an indirect advertisement of a corresponding program in interaction with a broadcast program being viewed by the user. Also, when the user sends, to a corresponding advertisement buddy as a message, a predetermined text, a brand name, a product picture, a QR code of a screen, and the like, with respect to the mid-program advertisement or the indirect advertisement of the program being viewed by the user, the program enabler service system may provide a service of providing the user with a reward. 
         [0099]      FIGS. 19A through 20B  are flowcharts illustrating a process of creating a program chatting room in the program enabler service system of  FIG. 18 . 
         [0100]    Referring to  FIGS. 19A and 19B , an execution engine  1823  of the program executor  1820  loads program information provided in a script format from the program creator  1810  and requests the chatting room control module  1845  to create a chatting room of a corresponding program ( 1901 ). Here, in the case of initiating a user participation using a character string matching method, the chatting room control module  1845  transfers a predetermined character string preset by a manager to the message control module  1842  as a message for requesting a program participation, in response to the request of the execution engine  1823  ( 1902 ). Also, the chatting room control module  1845  requests the buddy management module  1844  for a list of buddies having set a relationship with respect to an ID of the program manager ( 1903 ). In response thereto, the buddy management module  1844  transfers the buddy list registered to the ID of the manager to the chatting room control module  1845  ( 1904 ). Accordingly, the chatting room control module  1845  sends, to the mobile IM service platform  1850 , a message (hereinafter, a “participation request message”) for requesting all the users included in the buddy list for participating in a program. That is, the participation request message is sequentially transferred from the chatting room control module  1845  to the message control module  1842  of providing a function of identifying a message type, from the message control module  1842  to a recording module  1824  of providing an event recording function, from the recording module  1842  to a bus module  1827  of providing a message transfer function, and from the bus module  1827  to the mobile IM service platform  1850  through the legacy adaptor of the service connector  1830  ( 1905  through  1909 ). In this instance, the participation request message may be a predetermined character string preset by the manager. In response to the participation request message to a predetermined program received from the program enabler service system, the mobile IM service platform  1850  sends the participation request message to terminals (mobile IM application  1860 ) of all the users included in the buddy list of the manager ( 1910 ). 
         [0101]    Referring to  FIGS. 20A and 20B , the mobile IM application  1860  displays the participation request message received from the mobile IM service platform  1850 , receives a response message to the participation request message from a user, and transfers the response message to the mobile IM service platform  1850  ( 2001 ). In this instance, the mobile IM service platform  1850  transfers the response message to the program enabler service system of the manager through a legacy adaptor of the service connector  1830  ( 2002 ). The response message of the user is sequentially transferred from the legacy adaptor of the service connector  1830  to the bus module  1827  of providing a user authentication and message sending function, and from the bus module  1827  to the message control module  1842  of providing a function of determining whether a character string matches ( 2003  through  2005 ). Here, in the case of initiating the user participation using a character string matching method, the message control module  1842  may determine whether a predetermined character string is included in the response message. The message control module  1842  receives the intent for participating in the program from a user using the character string matching method or a general push method, and requests the chatting room control module  1845  to create a chatting room ( 2006 ). Accordingly, the chatting room control module  1845  opens a program chatting room in which the user having expressed the participation intent through the response to the program participation message participates. The chatting room control module  1845  may open a program chatting room for each episode of the broadcast program. Here, log information (manager ID, a user ID, a created date, etc) of the opened program chatting room may be recorded in the recording module  1824  ( 2007 ). 
         [0102]      FIGS. 21A through 21C  are flowcharts illustrating a process of providing a hint of a question in the program enabler service system of  FIG. 18 . 
         [0103]      FIGS. 21A through 21C , when a question including a hint is given during a program execution, the message control module  1842  of the mobile IM enabler  1840  provides a query message (question message) for giving a hint. Here, the question message indicates a hint giving question preset by a manager. The hint giving question is sequentially transferred from the message control module  1824  to the recording module  1824  of providing an event recording function, from the recording module  1824  to the bus module  1827  of providing a message transfer function, and from the bus module  1827  to the mobile IM service platform  1850  through the legacy adaptor of the service connector  1830  ( 2101  through  2104 ). In response to the hint giving question received from the program enabler service system, the mobile IM service platform  1850  transfers the received hint giving question to a terminal (mobile IM application  1860 ) of a user participating in the program chatting room ( 2105 ). 
         [0104]    The mobile IM application  1860  may activate a UI for inputting a “response” to a hint through the UI management module  1861  and may receive a response to the hint giving question from the user through the activated UI. Accordingly, the mobile IM application  1860  transfers the response of the user to the hint giving question to the mobile IM service platform  1850  ( 2106 ). The mobile IM service platform  1850  transfers the response message of the user to the program enabler service system of the manager through the legacy adaptor of the service connector  1830  ( 2107 ). The response of the user to the hint giving question is sequentially transferred from the legacy adaptor of the service connector  1830  to the bus module  1827  of providing a user authentication and message transfer function, and from the bus module  1827  to the message control module  1842  of providing a function of determining whether a character string matches ( 2108  through  2110 ). Here, the message control module  1842  may determine whether the response message received from the user to the hint giving question is a correct answer using the character string matching method. The message control module  1842  transfers the hint answer of the user to the response recording module  1846  to record whether the hint answer is a correct answer or an incorrect answer ( 2111 ). When the hint answer of the user is a correct answer, the message control module  1842  may send a hint message set for the hint giving question to a terminal (mobile IM application  1860 ) of the corresponding user through the aforementioned process ( 2101  through  2105 ). 
         [0105]    As an example different from the aforementioned example of using a hint giving question, a hint message to a given question may be provided using an advertisement. In detail, when a question including a hint is given during a program execution, the message control module  1842  of the mobile IM enabler  1840  sends a message including a preset advertisement to the mobile IM application  1860  of a user side through the mobile IM service platform  1850 . Accordingly, when the user takes an action such as inviting an advertisement buddy to a program chatting room or adding the advertisement buddy to a buddy list through a hyperlink to the advertisement within the message, and executing advertisement content, in response to the advertisement, a result of taking the action is transferred to the message control module  1842  as a user response to the advertisement. In this instance, the message control module  1842  may transfer a user response to the advertisement to the response recording module  1846  for its recording, and at the same time, may transfer a hint message set in the question to the user through the mobile IM application  1860 . 
         [0106]      FIGS. 22A through 22C  are flowcharts illustrating a process of providing an interactive question in which a condition is set between questions in the program enabler service system of  FIG. 18 . 
         [0107]    Referring to  FIGS. 22A through 22C , the message control module  1842  of the mobile IM enabler  1840  may determine whether there is any remaining question and whether the remaining question is an interactive question, and may request recording of a previous question when the remaining question to be given is the interactive question. As an example, the message control module  1842  may request the response recording module  1846  of providing a function of recording a correct answer or an incorrect answer for each user, to verify whether a response of a user to a previous question is a correct answer or an incorrect answer, or may request the statistics module  1843  of providing a statistical function for a correct/incorrect answer rate for each question, to verify a correct answer rate of the previous question ( 2201 ). The message control module  1842  may give a subsequent question based on records about the previous question, such as giving a subsequent question only to a user having sent a correct answer to the previous question through a response  2202  of the response recording module  1846 , or giving a subsequent question based on a correct answer rate of the previous question through the response  2202  of the statistics module  1843 . The given question is sequentially transferred from the message control module  1842  to the recording module  1824  of providing an event recording function, from the recording module  1824  to the bus module  1827  of providing a message transfer function, and from the bus module  1827  to the mobile IM service platform  1850  through the legacy adaptor of the service connector  1830  ( 2203  through  2206 ). In response to the question received from the program enabler service system, the mobile IM service platform  1850  sends the received question to a terminal (mobile IM application  1860 ) of a user having sent a correct answer to the previous question or a user participating in a program chatting room ( 2207 ). 
         [0108]    The mobile IM application  1860  displays the question received from the mobile IM service platform  1850 , receives a response message to the question from the user, and transfers the received response message to the mobile IM service platform  1850  ( 2208 ). In this instance, the mobile IM service platform  1850  transfers the response message to the program enabler service system of the manager through the legacy of the service connector  1830  ( 2209 ). The response of the user to the question is sequentially transferred from the legacy adaptor of the service connector  1830  to the bus module  1827  of providing a message transfer function, and from the bus module  1827  to the message control module  1842  of providing a function of determining whether a character string matches ( 2210  through  2212 ). In this instance, the message control module  1842  may determine whether the response message received from the user to the question is a correct answer using the character string matching method, and transfers the response message of the user to the response recording module  1846  to record whether the response of the user to the question is a correct answer or an incorrect answer. 
         [0109]    Accordingly, the program enabler service system according to the present invention may support an environment capable of directly executing an interactive broadcast program produced using an editor for producing the interactive broadcast program through association between the editor and various services. Further, the program enabler service system according to the present invention may aggressively use an advertisement as a means for providing a variety of additional information or services associated with a broadcast program. 
         [0110]    Hereinafter, a program enabler service method for providing a user participative interactive broadcast service will be described. Operations included in the program enabler service method according to the present invention may be performed by the program enabler service system of  FIG. 18 . 
         [0111]      FIG. 23  is a flowchart illustrating a method of creating, by a producer, an interactive broadcast program according to an embodiment of the present invention. 
         [0112]    Referring to  FIG. 23 , the program enabler service system may receive basic information of a program from a producer by providing an editor screen (FIG.  4 / FIG. 6 ) for inputting basic information of the program in response to a request of the producer (S 2301 ). In this instance, basic information of the program may include a name of the program, an episode of the program, cast information, and an air time (start time and end time). Here, the program enabler service system determines whether a buddy ID associated with the program is present (S 2302 ), and creates a buddy ID of the program when the buddy ID is absent (S 2303 ). When using a mobile IM as a communication channel with the user, a program manager is also regarded as a single buddy ID and the buddy ID associated with the corresponding program needs to be created to give a question and receive a response through the mobile IM. 
         [0113]    When the buddy ID of the program input from the producer is already present or when the buddy ID of the manager is created through the above process, the program enabler service system may receive a question to be given from the producer by providing an editor screen ( FIG. 6 ) for inputting a question to be given during a broadcasting (S 2304 ). The program enabler service system may receive, from the producer, contents of a question, consultation, a type of the question, and examples of a multiple-choice question through the question screen. When the producer is to provide a hint as an option associated with the question, the program enabler service system may receive a hint text, a target to receive a hint, a hinting method, and a hint query through an editor screen ( FIG. 8 ) for setting an option. Also, when providing a retry opportunity as another option, the program enabler service system may receive a retry opportunity assigning method and an estimated minimum response time through an editor screen ( FIG. 9 ) for setting an option (S 2305 ). In this instance, when using an advertisement as a means for providing a hint and a retry opportunity, the program enabler service system may set an advertisement providing method (that is, an advertisement buddy adding method, an advertisement buddy inviting method, and an advertisement push method), an advertisement buddy ID, link information of advertisement content, and the like, based on an input of the producer. 
         [0114]    When a question creation of the producer is completed (S 2306 ), the program enabler service system may receive a question giving order and a question giving method from the producer by providing an editor screen ( FIGS. 11 through 13 ) for setting a question solution process. That is, the program enabler service system may create an individual round (scene) for a predetermined episode of the broadcast program by creating a question solution process based on an input of the producer (S 2307  through S 2308 ). In this instance, when a detailed condition setting for connection between questions is required, the program enabler service system may receive a detailed condition associated with an interactive question from the producer through an editor screen ( FIG. 13 ) (S 2309  through S 2310 ). For example, when questions A and B are set as a question to be given in successive to a previous question, a detailed condition for selecting a subsequent question may be set by the producer based on a correct answer rate of a first question. 
         [0115]    When a creation of all the rounds for a predetermined episode of a broadcast program is completed through the aforementioned process, the program enabler service system may edit a user participation method with respect to the corresponding program (S 2311  and S 2312 ). As described above, through an exclusive editor, the program enabler service system may provide questions about the broadcast program and may set various options for each question. In particular, the program enabler service system may also set an advertisement option to give a hint or assign a retry opportunity associated with a corresponding question. 
         [0116]      FIG. 24  is a flowchart illustrating a method of creating, by a program manager, a program ID according to an embodiment of the present invention. 
         [0117]    The program manager refers to an operator operating an interactive service of a broadcast program, and is in charge of logging in the program enabler service system (that is, a portal module  1821 ) through a separate account and inputting and loading a basic interactive service creation condition. 
         [0118]    Referring to  FIG. 24 , when a new program (or a new episode) is selected by a manager, the program enabler service system registers a new buddy ID for each corresponding program (S 2401  and S 2402 ). 
         [0119]    In this instance, the program enabler service system may determine whether the buddy ID registered by the manager is duplicated, and may create a chatting room associated with the corresponding buddy ID when the buddy ID is determined not to be duplicated (S 2403  and S 2404 ). Accordingly, the program enabler service system may use the chatting room created based on the buddy ID of the manager as a communication channel for an interactive service of the corresponding program (S 2405 ). 
         [0120]    Accordingly, when using a mobile IM for an interactive service of a program, the program enabler service system may need to create a buddy ID of the manager and may create a chatting room (that is, a program participation room) based on the buddy ID of the manager. 
         [0121]      FIG. 25  is a flowchart illustrating a method of executing a broadcast program produced through an editor proposed herein in interaction with an interactive service enabler according to an embodiment of the present invention. 
         [0122]    Referring to  FIG. 25 , a program enabler service system may load corresponding program information provided in a script format in order to create a chatting room for a predetermined program at an arbitrary point in time (S 2501 ). That is, the program enabler service system may load chatting room creation information required for a corresponding episode by calling a service enabler (for example, the mobile IM enabler  1840 ) through a management module  1822  at an arbitrary program start point in time and by enabling the service enabler to load a program script created through the authoring module  1812 . 
         [0123]    The program enabler service system may determine a chatting room creation method (that is, whether to open a chatting room) and then may register a user as a participant in a corresponding program chatting room based on the determined chatting room creation method (S 2502  through S 2503 ). In the present embodiment, a predetermined character string input standby method and a push method with respect to a buddy list may be employed. 
         [0124]    Referring to  FIG. 26 , in a predetermined character string input standby method, even though a program enabler service system does not send a separate message, a user may directly execute a corresponding chatting room  2600  using a program ID and may input a “character string”  2601  indicating a program participation intent. Here, the “character string” indicating the program participation intent is notified to all the users viewing a program. For example, “start” and “participate” may be used as a predetermined character string indicating the program participation intent. That is, a mobile IM enabler of the program enabler service system may determine whether a character string input from a user through a chatting room of a program ID matches the predetermined character string indicating a broadcast program participation intent and when they match, may set the user as a buddy of the program ID. In this instance, when setting the user as the buddy of the program ID using the character string matching method, a buddy relationship with the program ID may be maintained during an air time of the broadcast program and a buddy setting with the user may be automatically canceled when the broadcast program is terminated. 
         [0125]    As another example, a buddy list target push method triggers a participation by sending a program start message to users having expressed a program participation intent in advance through making a friend with the program ID using the program enabler service system. Referring to  FIG. 27 , a program start message  2701  is pushed to all the users set as buddies and thus, a user may participate in a corresponding program by executing a chatting room  2700  at any time. That is, to trigger a participation in a broadcast program through a chatting room of the program ID, the mobile IM enabler of the program enabler service system may transfer a participation request message to users having set a buddy relationship in advance with the program ID using a message push method. 
         [0126]    The program enabler service system may provide program information to users participating in the program chatting room (S 2504 ). Here, in the case of a program that gives a question during an execution of the program, the program enabler service system determines whether there is any un-given question and closes the program chatting room when no question remains (S 2505  and S 2506 ). In contrast, when any question remains, the program enabler service system may provide a subsequent individual question. In addition, when any question currently remains and the remaining question is an interactive question that interacts based on a result of a previous question, the program enabler service system may determine whether a user response to the previous question is a correct answer or an incorrect answer, may limit a participation in the remaining question to a user having input an incorrect answer and may provide an individual question corresponding to the remaining question to a user having input a correct answer (S 2507  through  2510 ). 
         [0127]    The program enabler service system may verify whether a hint is set as a question option in providing an individual question and may give the hint of the corresponding question based on a predetermined hinting method (S 2511  and S 2512 ). 
         [0128]    As an example, when a hint is set to be given using an advertisement, the program enabler service system may provide a hint text of a corresponding question to a user inviting an advertisement buddy set in the question to a program chatting room. Referring to  FIG. 28 , when an “advertisement buddy inviting method” is set as the hinting method, the program enabler service system transfers a message (for example, “This question, you can get a hint from Sponsor Buddy.”)  2801  guiding that a hint is included in a corresponding question and an advertisement message  2802  including link information of an advertisement buddy through a program chatting room  2800 , and waits for a user response to the advertisement message  2802 . When the user invites the advertisement buddy included in the advertisement message  2802  to a current chatting room, the program enabler service system may provide a hint  2803  of the question given in operation S 2510 . As another example, referring to  FIG. 29 , when a user invites an advertisement buddy included in an advertisement message to a program chatting room  2900 , the program enabler service system may replace a background screen of the corresponding program chatting room  2900  with an advertisement image  2910  and then may give a hint to the user. In addition, an embodiment of using an advertisement, such as giving a hint to a user response using a method of adding an advertisement buddy to a buddy list of a user and a method of executing advertisement content (image display and playback of a video) connected to link information of the advertisement message may be configured various embodiments. 
         [0129]    As another example, when a hint is set to be given using a predetermined character string, the program enabler service system may transfer a hint giving question to the user through a predetermined character string, the program enabler service system may transfer a hint giving question to the user through the program chatting room. When the user inputs a character string that matches a correct answer of the hint giving question, the program enabler service system may provide a hint text. In detail, the program enabler service system may provide a query for giving a hint through the program chatting room, and then wait for an input of the user to the query. In this instance, the UI management module  1861  of the mobile IM application  1860  installed in a terminal of the user may provide an answer UI for inputting an “answer” to the question and a hint UI for inputting a “response” to the hint as UIs for user input in the program chatting room. That is, when the user creates a message in the program chatting room and uses the answer UI, it may be input as the answer to the question. When the user uses the hint UI, it may be input as the response to the hint. The program enabler service system may receive each response through a UI classified on the terminal of the user or may receive each response through combination of hash character string values. Accordingly, when a response to a hint giving query is received from the user through the program chatting room, the program enabler service system determines whether the response matches a hint query preset by the producer using the character string matching method. In this instance, when the response of the user to the hint giving query matches the preset hint query, the program enabler service system may give a hint of the question given in operation S 2510 . 
         [0130]    When a user response to the question given in operation S 2510  is received after the hint of the question is given, the program enabler service system may determine whether the user response is a correct answer or an incorrect answer, and may record the determination result for each user (S 2513  and S 2514 ). In this instance, when the answer of the user submitted in operation S 2513  is an incorrect answer, the program enabler service system may verify whether to provide a retry opportunity set by a producer and may provide the retry opportunity to the user having submitted the incorrect answer using a predetermined retry opportunity providing method (S 2515  and S 2516 ). 
         [0131]    As an example, when a retry opportunity is set to be provided using an advertisement, the program enabler service system may transfer a message including link information of the advertisement to a user through a program chatting room. When the user executes corresponding advertisement content through the link information of the advertisement included in the message, the retry opportunity that allows the user to submit an answer again may be assigned. Referring to  FIG. 30 , when an “advertisement push method” is set as a retry opportunity providing method, the program enabler service system may transfer an advertisement message  3002  including link information of advertisement content through a program chatting room  3000  to a user of which a submitted answer  3001  is an incorrect answer, and waits for a user response to the advertisement message  3002 . When the user executes the advertisement content through the link information included in the advertisement message  3002 , an advertisement execution screen  3010  is maintained during a running time. After the advertisement running time, the program enabler service system may transfer a message (for example, “please enter your answer again”)  3003  indicating a retry opportunity through the program chatting room  3000  and may receive again an answer  3004  of the user to the question. In addition, the retry opportunity may be assigned by applying an advertisement buddy adding method and an advertisement buddy inviting method. 
         [0132]    When a user response to a question is an incorrect answer and a time remaining by a question solution end time is greater than an advertisement running time or an estimated minimum response time, an advertisement for providing a retry opportunity may be provided. As another example, when providing the advertisement for providing a retry opportunity, the advertisement server may dynamically adjust a length of the advertisement to be less than the time remaining by the question solution end time and provide the length-adjusted advertisement through interaction with the program enabler service system. That is, the advertising effect may be optimized by providing advertisement contents having different running times. 
         [0133]      FIG. 31  is a flowchart illustrating a method of allowing a user to participate in a program on a terminal of the user according to an embodiment of the present invention. 
         [0134]    Referring to  FIG. 31 , a user terminal installs a mobile IM application in response to a request of a user (S 3101 ). In this instance, the mobile IM application, as a messenger program supported in a mobile environment such as Kakao Talk, Line, Tick Talk, and NATE ON, may indicate any type of messengers generally used. To participate in an interactive service program, the user needs to register a buddy ID of a corresponding manager to a buddy list through the mobile IM application installed in the terminal (S 3102  through S 3105 ). 
         [0135]    The user terminal maintains a program execution standby state when an actual broadcast program is not initiated yet (S 3106 ). Here, the program execution standby state may indicate a situation up to a time designated by the program manager (for example, 5 minutes before the program start). 
         [0136]    When the actual broadcast program starts, the user terminal may execute a chatting of the corresponding program using a program participation method designated by the program manager for triggering the user to participate in a program through the mobile IM application (S 3107  and S 3108 ). In the present embodiment, the chatting room of the corresponding program may be executed using a predetermined character string input standby method ( FIG. 26 ) and a buddy list target push method ( FIG. 27 ). That is, in the case of using the predetermined character string input standby method, the user may participate in the broadcast program by directly executing a program chatting room using a program ID and by inputting a predetermined character string in the program chatting room. Also, in the case of using the buddy list target push method, the user may participate in the broadcast program by executing a program chatting room at a point in time when a participation request message is received from the program enabler service system in a state in which the user has registered the program ID to a buddy list of the user in advance. 
         [0137]    The user terminal may receive a question given during a program execution from the program enabler service system, and may display the received question through a program chatting room of the mobile IM (S 3109 ). Accordingly, the user may verify the question through a TV screen on which the corresponding program is on air and a conversation window of the mobile IM. Also, when a given question is a hint giving question, the user terminal may receive an advertisement message including link information of an advertisement from the program enabler service system and may display the advertisement message through the program chatting room (see  FIGS. 28 and 29 ). As an example, when a hint giving method is set as an advertisement buddy adding method and an advertisement buddy included in the advertisement message is added to a buddy list of the user (S 3110 ), the user terminal may display a hint of the question given from the program enabler service system on the program chatting room to be verifiable by the user (S 3111 ). As another example, when the question is a hint giving question, the user terminal may receive a query for giving a hint from the program enabler service system and may display a hint query through the program chatting room In this instance, the user terminal may receive a response to the hint query from the user and may transfer the received response to the program enabler service system. The program enabler service system may display the hint of the question in the program chatting room to be verified by the user, based on a hint query matching result. 
         [0138]    When the user verifies the hint and inputs a response to the question, the user terminal may transfer the response to the program enabler service system and the program enabler service system may display a result of verifying whether the response is a correct answer or an incorrect answer on the program chatting room to be verifiable by the user (S 3112  and S 3113 ). In this instance, with respect to a question that provides a retry opportunity to a user having submitted an incorrect answer, the user terminal may receive an advertisement message including link information of an advertisement from the program enabler service system, and may display the advertisement message through the program chatting room (see  FIG. 30 ). As an example, when an advertisement push method is set as a retry opportunity providing method and the user selects click information of the advertisement message in the program chatting room, the user terminal may execute corresponding broadcast content during a running time so that the user may view the advertisement (S 3114 ). Accordingly, when the user completes viewing the advertisement, the program enabler service system transfers a message indicating a retry opportunity to the user through the program chatting room and receives again an answer of the user to the question. 
         [0139]    The user terminal may maintain the user&#39;s participation in the program until the program is terminated (S 3115 ). That is, even though the user executes another application after participating in the program chatting room, the program enabler service system recognizes that the user is to maintain the participation in the corresponding program unless the user selects a separate program participation end. Also, when a corresponding episode of the program is terminated after the user participates in the program chatting room, the program enabler service system may terminate an instance of a corresponding service and the user may leave the participating program chatting room. In this instance, when the user is to participate in a subsequent episode of the program in a state of maintaining a chatting room after the program is terminated, the user needs to express the intent regarding whether to participate in this episode. In this case, similarly, a participation character string input request message may be sent to the user and the user may participate in the corresponding program by inputting a character string. 
         [0140]    The program enabler service method described above with reference to  FIGS. 23 through 31  may include a reduced number of operations or additional operations. Also, at least two operations may be combined and orders or locations of operations may be changed. 
         [0141]    As described above, according to embodiments of the present invention, there is provided a system in which an editor for producing an interactive broadcast program and an enabler capable of associating and thereby executing a broadcast program produced through the editor with existing communication channels are combined and thus, it is possible to format program information and thereby improve the production and management efficiency. Also, it is possible to easily and conveniently provide various communication functions required for the interactive broadcast program. 
         [0142]    The methods according to embodiments of the present invention may be recorded in non-transitory computer-readable media including program instructions to implement various operations embodied by a computer. The media may also include, alone or in combination with the program instructions, data files, data structures, and the like. The program instructions recorded in the media may be those specially designed and constructed for the purposes of the present invention, or they may be of the kind well-known and available to shoes having skill in the computer software arts. Also, the file systems may be recorded in the non-transitory computer readable media. 
         [0143]    Although a few embodiments of the present invention have been shown and described, the present invention is not limited to the described embodiments. Instead, it would be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
