Hereinafter, an IPTV remote viewing control system using a mobile terminal will be described in more detail with reference to FIGS. 3 and 4.

As shown in FIG. 3 and FIG. 4, the above-described IPTV broadcasting system 20 includes an STB interface (I / F) server 100 connected to a set-top box provided in the IPTV, and a WAP I connected to the mobile terminal 10. / F server 120 or SMS I / F server 130, legacy I / F server 150 connected to the head-end system 180, and each of the I / F server (100, 120, A DB server 160 storing a single type of method corresponding to a command converted into a single type of method call provided at 130 and 150; and calling the method corresponding to the command to the IPTV headend. An IPTV broadcasting system 20 including a control server 160 for controlling a system or the set-top box and transmitting a control result to a mobile terminal.

Here, the control server 160 is provided with a user information DB separately, but may be integrated with the control server 160.

The STB I / F server 100 is a server connected to the set-top box 30, and may work with the control server 160 to reflect IPTV activation and viewing control. That is, when the screen of the IPTV installed in the home is turned on, the STB I / F server 100 transmits the command converted into a single type of method call to the DB server 160, and the control server 140 is the DB server 160 As a result of calling the method corresponding to the command stored in the), for example, the IPTV activation or the control request from the mobile terminal 10 is transmitted to the set-top box 30 again.

The WAP I / F server 120 is a server connected with the mobile terminal 10 and the WAP gateway 400, interworking with the control server 160 to inquire the viewing program history, and the set-top box 30. It is possible to control. More specifically, the WAP I / F server 120 transmits a command converted into a single kind of method call to the DB server 160, and the control server 140 sends a method corresponding to the command stored in the DB server 160. Call and transmit the processing result to the mobile terminal 10 or the set-top box 30.

This processing result is, for example, in response to the viewing history inquiry request from the WAP I / F server 120, inquires the service history of the headend system 180, or the WAP I / F server 120 In response to the set-top box control command from the user, the result of controlling the set-top box based on the state information of the set-top box 10 and the service subscription information in the head-end system that can confirm the user subscription by the control server 140. .

The SMS I / F server 130 is a server connected with the mobile terminal 10 and the ISMC 300, and notifies the mobile terminal 10 whether the IPTV is activated 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 via the SMS I / F server 130 as an SMS text message to the mobile terminal 10. To be sent).

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

That is, the legacy I / F server 150 transmits a command converted into a single type of method call to the DB server 160, and the control server 140 calls a method corresponding to the command stored in the DB server 160. The processing result is transmitted to the headend 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 converts the command into a single type of method call provided by the I / F servers. Store the corresponding single kind of method.

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

More specifically, the control server 140 calls a method call corresponding to each server to process a command corresponding to the method call, and then receives program information according to the corresponding command from the headend system 180 The data is transmitted to the WAP I / F server 120 or the STB I / F server 130.

By doing so, the control server 140 processes a command such as viewing a program and requesting control of the set-top box 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 180 or the set-top box 30, and by transmitting the control result back to the mobile terminal, monitoring and querying the viewing program information transmitted on the IPTV screen of the home at a remote location, Therefore, 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 the command converted into a single type of method call is called between each I / F server and the control server, command conflicts between each I / F server do not occur.

In addition, in the case of mobile services of other protocols or communication methods, IPTV remote control service can be easily and flexibly extended by adding an I / F server that converts each command into a single method call.

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

Table 1 shows the source of the method used in the method call as described above, the control commands and server operations corresponding thereto.

Method call source Control instruction Server behavior CFG1001 (String, LinkedHashMap) IPTV Off Request (STB I / F Server → STB) CFG1002 (HashMap) IPTV channel restriction request (WAP I / F Server → WAP) CFG1002 (String, LinkedHashMap) IPTV channel restriction request (STB I / F Server → STB) CFG1002 (Document, String) IPTV channel restriction request (STB → STB I / F Server) CFG1301 (HashMap) Request IPTV On Notification Settings (WAP → WAP I / F Server) CFG1301 (ActionMapping, ActionForm, HttpServletRequest, HttpServletResponse) Request IPTV On Notification Settings (SMS Server → SMS I / F Server) CTL1001 (HashMap) IPTV Off Request (WAP → 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, since the control server 140 processes the control command by calling the method shown in Table 1 corresponding to the command converted into a single type of method call in each I / F server, there is no command conflict for each I / F server. Through the mobile terminal 10, the set top box 30 may be controlled to enable viewing of a viewing program and restriction of viewing of an IPTV.

On the other hand, the control server 140 is provided with 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 querying a viewing program of an IPTV at a remote location using a mobile terminal according to the present invention.

First, when the screen of the home IPTV is turned on in step S100, the STB I / F server 100 connected to the set-top box 30 is a method corresponding to the command converted to a single type of method call for IPTV activation. Save to DB server. Thereafter, the stored method is called by the control server 140, and the control server 140 based on the remote control service subscription information from the headend system 180, and the information between the control server 140 and the set-top box 30. Activate IPTV to make it possible to send. The step of activating the above-described IPTV is described in more detail in FIG.

Then, in step S110, the user who wants to watch the remote access 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, the mobile terminal 10 Check whether or not the user of) is subscribed to the headend system 180. The above-described user registration confirmation step is described in more detail with reference to FIG. 7.

In addition, when the user subscription confirmation is made in step S120, in order to request the viewing of the viewing history of the program, the WAP I / F server 120 connected to the mobile terminal 10 is a single type of method call for viewing the viewing history. Save the method corresponding to the converted command in the DB server.

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

Then, if the viewing history query fails according to the viewing history inquiry result received from the headend system 180 via the legacy I / F server 150 in step S140 (step S170), the control server 140 Transmits the inquiry failure result to the mobile terminal 10 via the WAP I / F server 120 (step S180).

In addition, if the user of the mobile terminal 10 wants to check the viewing history of the program again, the process proceeds to step S120 and repeats the above process.

On the other hand, if the viewing history query 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 / F server is stored in the control server ( 140) (step S150). The control server 140 receiving the service history 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, since the method corresponding to the command converted into a single type of method call is called between each I / F server and the control server connected to the mobile terminal and the set-top box, the viewing program information displayed on the IPTV is inquired. And security can be enhanced.

In addition, it is possible to control the set-top box installed in the home IPTV through a command corresponding to a single type of method while monitoring and viewing the viewing program information from a remote location using a mobile terminal, thereby controlling the children's reckless viewing habits from the outside. It is possible to. For example, you can power off the IPTV by turning the set-top box off or on.

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

First, in step S210, when the viewer turns on the IPTV in the home, the STB I / F server 100 connected to the set-top box 30 corresponds to a value for the status information of the set-top box 30. The method call is converted into a method call, and the method for executing through a command corresponding to the converted method call is stored in the DB server 160. Thereafter, the control server 140 calls a method corresponding to the command from the DB server 160, while the control server 140 subscribes the control service to the headend system 180 based on the called method. Ask for confirmation.

If the control service subscription is not confirmed, the headend 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. In addition, when the control service subscription is confirmed by the head-end system 180, the process proceeds to step S260.

However, in step S260, if the mobile terminal 10 is set to not receive the activation state indicating the on state of the IPTV, the SMS I / F server 130 does not send an SMS text message for notifying the IPTV activation. Transmit (step S280).

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

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

First, in step S300, a user of a mobile terminal that wants to watch and watch an IPTV in a home, inputs user information ID and PW. The WAP I / F server 120 or the SMS I / F server 130 which has received the input information converts the method call into a method call corresponding to the input information, and executes it through an instruction corresponding to the converted method call. Save the method to the DB server 160. Thereafter, the control server 140 calls a method corresponding to the command from the DB server 160, while the control server 140 inquires the user information DB in which user information is accumulated (S310).

If, as a result of inquiring the user information DB by the control server 140, if the mobile terminal 10 is not registered, any one of each I / F server (120, 130) connected to the mobile terminal 10 Notify the non-subscription to the mobile terminal 10 through.

Thereafter, when the control server 140 inquires the user information DB in step S310, if the subscription state is confirmed, the process proceeds to step S320 and the control server 140 returns to the headend system 180 again. Ask to see user registration information once.

If, as a result of inquiring user information from the HDS (Home Digital Server) of the headend system 180, if the mobile terminal 10 is in the unsubscribed state, the non-subscribed user information is stored in the DB (step S330). When the user terminates the IPTV service, the process of requesting confirmation of user subscription of the headend system 180 may be reduced. In operation S340, the mobile terminal 10 is notified of the non-subscription through any one of the respective I / F servers 120 and 130 connected to the mobile terminal 10.

Then, when the headend system 180 inquires the user information in step S320, if the subscription state is confirmed, the control server 140 checks the legacy user registration result provided by the headend system 180 in the legacy I / A. It receives through the F server 150, and notifies the mobile terminal 10 of the received user subscription confirmation result to the mobile terminal 10 through any one of the I / F server (120, 130).

However, the present invention is not limited to the above scheme, and it is also possible to execute the inquiry directly through the headend system 180 without inquiring the user information DB in the control server 140.

In an embodiment of the present invention, it is not limited to the use of a mobile terminal to provide a remote viewing control service for an IPTV, but it is also possible to use a portable terminal such as a PC or a PDA.

When the subscription to the IPTV remote control service is confirmed according to the embodiment shown in FIG. Is converted to a single type of method call on the SMS I / F server or WAP I / F server and forwarded to the remote control server.

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

One embodiment of the present invention can also be implemented in the form of a recording medium containing instructions executable by a computer, such as a program module executed by the 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, computer readable media 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.
