Here, the control server 160 may have a separate user information DB, but may be integrally formed with the control server 160.

The STB I / F server 100 is a server connected to the set-top box 30, and can interact with the control server 160 to reflect IPTV activation and viewing control. That is, when the IPTV screen installed in the house is turned on, the STB I / F server 100 transmits a command converted into a single type of method call to the DB server 160, and the control server 140 transmits the converted command to the DB server 160 For example, IPTV activation or control request from the mobile terminal 10, to the set-top box 30 again.

The WAP I / F server 120 is a server connected to the mobile terminal 10 via the WAP gateways 400. The WAP I / F server 120 inquires the viewing program details in cooperation with the control server 160, It is possible to control it. More specifically, the WAP I / F server 120 transmits a command converted into a single type of method call to the DB server 160, and the control server 140 transmits a method corresponding to the command stored in the DB server 160 And transmits the processed result to the mobile terminal 10 or the set-top box 30.

The result of this processing is transmitted to the WAP I / F server 120, for example, by inquiring the service history of the headend system 180 in response to a viewing history inquiry request from the WAP I / F server 120, In response to the set-top box control command from the control server 140, status information of the set-top box 10 and control information of the set-top box based on the service subscription information in the head end system capable of confirming the user's subscription by the control server 140 .

The SMS I / F server 130 is a server connected to the mobile terminal 10 via the ISMC 300. The SMS I / F server 130 notifies the mobile terminal 10 of activation of the IPTV in cooperation with the control server 160.

That is, when the mobile terminal 10 is set to receive the activation of the IPTV, the control server 40 transmits the IPTV activation processing result to the mobile terminal 10 via the SMS I / F server 130, .

The legacy I / F server 150 is connected to a head end system 180 which is an external server and transmits information such as a viewing program transmitted from the head end system 180 to the control server 140.

That is, the legacy I / F server 150 transmits an instruction converted into a single type of method call to the DB server 160, and the control server 140 calls a method corresponding to the instruction stored in the DB server 160 And transmits the processed result to the head end system 180 again.

The DB server 160 is a server connected to each of the I / F servers 100, 120, 130, and 150. The DB server 160 receives a command converted into a single type of method call provided from the I / And stores the corresponding single kind of method.

The control server 140 calls the method corresponding to the command stored in the DB server 160 to control the IPTV head end system 180 and the set top box 30 and transmits the control result to the mobile terminal.

More specifically, the control server 140 calls a method call corresponding to each server, processes a command corresponding to the method call, and receives program information or the like according to the command from the head end system 180 And transmits the data to the WAP I / F server 120 or the STB I / F server 130.

The control server 140 processes commands such as viewing program inquiry and set-top box control 30 requested through the WAP I / F server 120 or the SMS I / F server connected to the mobile terminal, It is possible to control the set-top box 180 or the set-top box 30. By transmitting the control result to the mobile terminal again, it is possible to monitor and inquire the viewing program information transmitted on the in-house IPTV screen, It is possible to control the output of the IPTV through the set-top box control.

In addition, since a single type of method corresponding to a command converted into a single type of method call is called between each I / F server and the control server, no instruction conflict between each I / F server occurs.

In addition, even in the case of mobile services of different protocols or communication methods, it is possible to easily and flexibly extend the IPTV remote control service by adding an I / F server that converts each command into a single type of method call.

Here, the control server 140 may be implemented as a system of WAS (Web Application Server), and the single type of method call described above may be implemented as a Java program such as EJB.

Table 1 shows a table in which a source used for a method used in a method call as described above, a control command corresponding thereto, and a server operation are tabulated.

Method call source Control command Server behavior CFG1001 (String, LinkedHashMap) IPTV off request (STB I / F Server?

WAP I / F Server) CTL1001 (String, LinkedHashMap) IPTV off request (STB I / F Server? STB) CTL1001 (Document, String) IPTV off request (STB I / F Server? STB)

In this way, the control server 140 calls the methods of Table 1 corresponding to the instruction converted into a single type of method call in each I / F server and processes the control instruction, The set-top box 30 can be controlled so that viewing program viewing and IPTV viewing restriction can be performed through the mobile terminal 10.

Meanwhile, the control server 140 may include a user subscription information DB that stores user subscription information subscribed to the head end system 180, but may be provided integrally with the control server 140.

5 is a flowchart illustrating a method of inquiring an IPTV viewing program at a remote location using a mobile terminal according to the present invention.

First, in step S100, when a home IPTV screen is turned on, the STB I / F server 100 connected to the set-top box 30 transmits a method corresponding to a command converted into a single type of method call for activating IPTV DB server. Then, the control server 140 calls the stored method, and the control server 140 receives information about the information between the control server 140 and the set-top box 30 based on the remote control service subscription information from the headend system 180 To enable IPTV to be transmitted. The step of activating the IPTV described above will be described in more detail in Fig.

Then, in step S110, the user who wants to watch the remote terminal accesses the wireless Internet WAP server via the WAP G / W using the Internet access means such as WINC or SMS of the mobile terminal 10, ) Is subscribed to the head-end system (180). The above-described user subscription confirmation step will be described in more detail in Fig.

If the user subscription confirmation is made in step S120, the WAP I / F server 120 connected to the mobile terminal 10 requests the viewing of the program by a single type of method call And stores the method corresponding to the converted command in the DB server.

Thereafter, in step S130, the control server 140 calls the stored method, and the control server 140 requests inquiry to the headend system 180 via the legacy I / F server 150, End system 180 inquires about the viewing history of the program to be provided to the set-top box 30.

If the viewing history information inquiry fails (step S170) in accordance with the viewing history information received from the head end system 180 via the legacy I / F server 150 in step S140, Transmits a query failure result to the mobile terminal 10 via the WAP I / F server 120 (step S180).

If the user of the mobile terminal 10 wishes to inquire the viewing details of the program again, the process proceeds to step S120 and the above process is repeated.

On the other hand, when the viewing result of the program is successful, the service history, such as viewing time and content name, is stored in the legacy I / F server, and the viewing time and content name stored in the legacy I / 140 (step S150). The control server 140 receiving the service details including the viewing time and the content name transmits the viewing time and the content name to the mobile terminal 10 via the WAP I / F server 120 (step S160).

As described above, the method corresponding to a command converted into a single kind of method call is called between each I / F server connected to the mobile terminal and the set-top box and the control server, and the viewing program information displayed in the IPTV is inquired, And security.

In addition, it is possible to control the set-top box installed in the IPTV of the house through commands corresponding to a single kind of method while monitoring and inquiring the viewing program information from a remote place using the mobile terminal. Therefore, It is possible to do. For example, IPTV can be turned off by setting the set-top box to turn off immediately or to turn off the reservation.

6 is a flowchart of a method for activating IPTV according to an embodiment of the present invention.

First, in step S210, when the viewer turns on the IPTV at home, the STB I / F server 100 connected to the set-top box 30 corresponds to the value of the state information of the set-top box 30 And stores the method in the DB server 160 so as to be executable through a command corresponding to the converted method call. Thereafter, the control server 140 calls the method corresponding to the command from the DB server 160, and on the basis of the called method, the control server 140 notifies the head end system 180 of whether the control service is subscribed .

If the control service subscription is not confirmed, the head end system 180 requests registration of the control service subscription information to the WAP I / F server, and updates the control service subscription information when the subscription information is registered. Thereafter, in step S250, the control server 140 notifies the mobile terminal 10 of the activation information of the IPTV, and proceeds to step S260. Also, if the subscription of the control service is confirmed by the head end system 180, the process also proceeds to step S260.

However, if it is determined in step S260 that the mobile terminal 10 does not receive the activation state indicating the on state of the IPTV, the SMS I / F server 130 transmits an SMS text message for notifying the activation of the IPTV (Step S280).

On the contrary, when the mobile terminal 10 is set to receive the activation state indicating the on state of the IPTV, the SMS I / F server 130 transmits an SMS text message for notifying the activation of the IPTV to the mobile terminal 10 via the ISMC (Step S270).

7 is a flowchart illustrating a method for confirming a user subscription for IPTV remote viewing control using a mobile terminal according to an exemplary embodiment of the present invention.

First, in step S300, the user of the mobile terminal who wants to watch the IPTV in the house inputs user information (ID, PW) and the like. The WAP I / F server 120 or the SMS I / F server 130 that has received the input information converts the input information into a method call corresponding to the input information, and executes the converted method call through a command corresponding to the converted method call To the DB server 160. [0050] Thereafter, the control server 140 calls the method corresponding to the command from the DB server 160, and the control server 140 inquires the accumulated user information DB (S310).

If the mobile terminal 10 is in an unplugged state as a result of inquiring of the user information DB by the control server 140, any of the I / F servers 120 and 130 connected to the mobile terminal 10 Notifies the mobile terminal 10 of the non-insertion.

Thereafter, when the control server 140 inquires the user information DB in step S310, if the subscription status is confirmed, the control server 140 proceeds to step S320 and returns to the head end system 180 again And requests to inquire user subscription information once.

If it is determined that the mobile terminal 10 is in the non-inserted state as a result of inquiring the user information in the home digital server (HDS) of the headend system 180, the unused state information is stored in the DB (step S330) It is possible to reduce the process of requesting confirmation of the user subscription of the headend system 180 when the user has canceled the IPTV service. In step S340, the mobile terminal 10 notifies the mobile terminal 10 through the I / F server 120 or 130 connected to the mobile terminal 10 that the mobile terminal 10 is not inserted.

When the subscriber status is confirmed when the head end system 180 inquires the user information in step S320, the control server 140 transmits the user subscription confirmation result provided from the head end system 180 to the legacy I / F server 150 and notifies the mobile terminal 10 of the result of the received user subscription confirmation through any one of the I / F servers 120 and 130.

However, it is also possible to execute the inquiry directly through the head end system 180 without inquiring the user information DB in the control server 140, without being limited to the above method.

In the embodiment of the present invention, it is possible to use a portable terminal such as a PC or PDA instead of the use of a mobile terminal to provide a remote viewing and controlling service for IPTV.

When an IPTV remote control service subscription is confirmed by the embodiment shown in FIG. 7, an IPTV control command (for example, IPTV deactivation, prohibition of downloading of charged contents, viewing time restriction, etc.) Is converted into a single type of method call in the SMS I / F server or the WAP I / F server, and is transmitted to the remote control server.

The method corresponding to the method call is converted into an IPTV remote control command in the legacy I / F server or the STB I / F server to perform IPTV remote control corresponding to a predetermined command.

One embodiment of the present invention may also be embodied in the form of a recording medium including instructions executable by a computer, such as program modules, being executed by a computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes any information delivery media, including computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transport mechanism.
