[ We have made it possible to share information efficiently so that data (pictures, videos, documents, etc.) can be viewed together freely and collaborative work such as writing can be freely performed.

2 is a view for explaining an IPTV terminal 110 according to an embodiment of the present invention.

2, the IPTV terminal 110 according to an exemplary embodiment of the present invention includes a set-top box 112. The set-top box 112 includes a controller 210, a memory 211, a user interface 212, An IPTV module 220, a call module 230 and a sharing module 240. [ All of the components of the set-top box 112 may be hardware, software, or a combination thereof. The controller 210 controls the overall operation of all the components of the set-top box 112, May be implemented to include some functionality of the components.

The user interface 212 is used for setting necessary settings (channel, recording reservation, recording reservation, etc.) for proper operation of the components of the set top box 112 such as the memory 211, the IPTV module 220, the currency module 230, Screen brightness / color, and the like) through the display unit or the display unit 111. The set-top box 112 displays the menu or the like through its own display unit or display unit 111, Supports proper operation.

The IPTV module 220 supports the broadcasting program contents provided by the broadcasting server 115 connected via a network such as the Internet to be viewed through the display device 111. [ The IPTV module 220 is authenticated by the broadcast server 115 through a unique identifier such as a MAC (Media Access Control) address, and receives the broadcast program contents (news, movies, drama , Music, and the like) at any time and at any time.

In particular, a minimum program (Launcher) may be stored in the memory 211 to support the operation of the IPTV terminal 110 and to provide a SIP-based VoIP call function and an HTTP-based sharing function. The control unit 210 may start the operation of the set-top box 112 by executing the Launcher at the time of the initial installation, and may be added through the network such as the Internet so that the communication module 230 and the sharing module 240 can operate normally. You can download and install the full package program. A full package program is stored in the memory 211 and is executed by the control unit 210 to request an IPTV terminal identifier (e.g., a SIP telephone number), so that the terminal management server 120 on the network can request an IPTV terminal identifier The control unit 210 receives and stores an IPTV terminal identifier (e.g., a SIP telephone number) given to the set-top box 112, and uses the IPTV terminal identifier It can be used as an identifier (e.g., telephone number) for VoIP call function to control voice and video call support.

The call module 230 performs a call function through a network such as the Internet based on the SIP using the IPTV terminal identifier (for example, SIP phone number) granted as above, and the sharing module 240 interworks with the call module 230 And performs a sharing function through the network using HTTP.

The other external user terminals providing the IP-based VoIP communication function and the HTTP-based sharing function with the IPTV terminal 110 also include the communication module 230 and the sharing module 240 as described above, Can communicate with the IPTV terminal 110 via a network such as the Internet using a unique terminal identifier (e.g., telephone number) through a communication module of its own, and the own shared module and the communication module are linked And can perform a sharing function with the IPTV terminal 110 via the network using HTTP.

In FIG. 1, the application server 130 relays the IPTV terminal 110 to make a SIP-based VoIP video call with another external user terminal through the call module 230 on the network. The SIP protocol is one of the protocols for enabling VoIP calls, and enables callers and called terminals on the network to access the Internet to enable efficient VoIP calls.

When a shared event occurs during a video call between terminals via the above-described communication module, the sharing server 140 transmits a request to the user terminal (IPTV terminal, external terminal) Relay to enable data sharing (media sharing, document sharing, drafting, etc.). The shared server 140 and the user terminal (IPTV terminal, external terminal) can be connected to exchange signals required by the SOAP (Simple Object Access Protocol) connection technology in the internet protocol for enabling free connection between platforms, The method is based on HTTP.

Similarly, the sharing module of the user terminal (IPTV terminal, external terminal) and the sharing server 140 access the UCLOUD server 150 in the HTTP-based transmission technology and the SOAP connection method and transmit the digital multimedia data stored in the UCLOUD server 150 Or upload data to the UCLOUD server 150. [ The user terminal (IPTV terminal, external terminal) can communicate internally between the shared server 140 and the application server 130 using the HTTP-based transmission technology and the SOAP access method. Application Programming Interface) communication can be performed. The API makes it possible to easily control the corresponding response or the corresponding command according to a limited range of data request or control command among the modules by using a predetermined function. That is, the search result and the user interface (UI) are unilaterally provided unilaterally, and data can be requested to each module through an API opened between the modules, and the necessary user interface can be controlled through the control command.

As shown in FIG. 3, images of the respective users photographed using the cameras of the respective terminals (IPTV terminal, external terminal) during the video call can be displayed on the divided screens of the terminals, respectively. At this time, A sharing event is generated in the case of a selection of a view button (or a sharing button) or a connection of a video call of a new participant and the sharing event is generated in FIG. 4 (document sharing) Game sharing), and according to each function selection on the screen, among the shared services as shown in FIGS. 4 to 7, the image of each user photographed using the camera of each terminal, A sharing screen for media sharing, document sharing, game sharing, and pen sharing can be displayed on divided screens of each terminal.

8 to 13, a communication module and a sharing module of a user terminal (IPTV terminal, external terminal) according to an embodiment of the present invention are connected to a shared server 140, an application server 130, A service method for sharing digital multimedia data between terminals will be described in more detail.

8 is a flow chart illustrating a shared session connection according to an embodiment of the present invention.

First, a user can make a video call with the other party (s) by selecting the other party's phone number and SIP call button through the terminal (IPTV terminal / external terminal), and the call module of each terminal is connected to the application server 130 (SIP) -based (VoIP) video call (or voice call, the same applies to the following) (S11). At this time, as shown in FIG. 3, images of respective users photographed using cameras of respective terminals (IPTV terminal / external terminal) in a video call can be displayed on divided screens of the terminals, respectively. At this time, In the case of the selection of the view button (or the sharing button), the screen can be switched to the shared screen (S12).

For example, when a view button (or a share button) is selected in a terminal (a sharing subject or a sharing requestor) in a video call and a sharing request is generated, the application server 130 transmits an identifier The shared server 140 may transmit the conference room unique key value (e.g., conference room unique key value) to the shared server 140 (S13) (IP address, port number, OTP (One Time Password), etc.) to the application server 130 (S14).

Accordingly, the application server 130 transmits the server connection information to the call module of each terminal (terminals in video communication or terminals to be shared), and each terminal transmits server connection information (IP address, Port number, OTP, etc.) to the sharing module via the API (S15). Thereafter, the shared module of each terminal transmits the server connection information (IP address, port number, OTP, etc.) to the shared server 140 based on HTTP, and can access the shared server 140 (S16) The other party terminal may be disabled such that the view button (or the share button) can not be selected together on the screen by the operation of the sharing module.

When the terminal is connected to the sharing server 140, the sharing module of the terminal, which is the subject of sharing, requests the sharing main screen as the communication module (S17), and the corresponding command is executed by the operation of the communication module (S18) A shared main screen can be activated on the screen, and if the digital multimedia data to be shared such as an image, a moving picture, or a document is selected in the shared main screen, the shared main body and the partner terminal (plural) It is possible to share media among the users. For example, if digital multimedia data is selected in the terminal of the sharing subject, the sharing event can be transmitted to the sharing server 140 (S19). If the other terminal receives the sharing event via the sharing server 140, The shared main screen (or the shared screen) can be activated on the screen by executing the corresponding command by the operation of the communication module (S18) (refer to FIGS. 4 to 7) Accordingly, the shared digital multimedia data selected from the terminal of the sharing subject such as image, moving picture, document, etc. can be synchronized with the terminal of the sharing subject through simultaneous viewing on both sides through the shared screen.

Thereafter, the sharing subject and the other terminal (s) can select one from the shared main screen and the digital multimedia data list provided by the shared server 140, and all the sharing terminals simultaneously share the same image, , Documents and the like can be shared and can be viewed through a video call while sharing, and if necessary, a book or an edit to be input by each user to an image, a moving picture, a document displayed on a shared screen, The server 140 can relay such modified and changed data to be displayed and stored in the same synchronized manner in each shared terminal.

In addition, all the sharing terminals may upload digital multimedia data stored in its own memory or digital multimedia data downloaded from the UCLOUD server 150 to the sharing server 140, and the sharing server 140 may share all the sharing terminals And provide the list including the digital multimedia data stored and maintained in the UCLOUD server 150 when providing the digital multimedia data list to the UCLOUD server 150. [

Figure 9 is a flow chart illustrating sharing participant addition according to an embodiment of the present invention.

Here, as shown in FIG. 8, when a new participant's video call is connected after a sharing is performed between terminals, a sharing event occurs and a new participant's terminal participates in sharing.

8, when a new participant terminal is connected with a SIP-based (VoIP) video call with a terminal (shared subject) that originated the sharing request in FIG. 8 (S21) , A new participant terminal can additionally participate in the corresponding share as follows.

For example, when a new participant terminal is connected with a SIP-based (VoIP) video call with a terminal (shared subject) that originated the sharing request in FIG. 8 (S21), the application server 130 transmits an identifier The shared server 140 may transmit the participant information including the new participant (the number of participants, the participant phone number, etc.) and the conference room unique key value (e.g., Conf ID) to the shared server 140 (S22) (IP address, port number, OTP (One Time Password), etc.) along with the conference room unique key value (e.g., Conf ID) to the application server 130 (S23).

Accordingly, the application server 130 additionally transmits the server connection information to the communication module of the new participant terminal. In the new participant terminal, the server connection information (IP address, port number, OTP, etc.) To the shared module (S24). Thereafter, the shared module of the new participant terminal can access the shared server 140 by transmitting server connection information (IP address, port number, OTP, etc.) to the shared server 140 based on HTTP (S25). At this time, since the new participant terminal is not the subject of sharing, it can be disabled such that the view button (or the share button) can not be selected together on the screen by the operation of the shared module.

When a new participant terminal is connected to the sharing server 140 and a sharing event is received through the sharing server 140 at step S26, the sharing module requests a shared main screen as a communication module at step S27, The corresponding command is executed by the operation of the module (S28), and the shared main screen (or the shared screen) can be activated on the screen. Accordingly, the new participant terminal can additionally display the existing shared terminals The digital multimedia data such as images, moving images, and documents provided by the shared server 140 can be supported by the sharing server 140, such as media sharing, document sharing, and desk sharing.

FIG. 10 is a flowchart illustrating a sharer deletion at the end of a call of a share participant according to an embodiment of the present invention.

Here, as shown in FIG. 8 or 9, after the terminal is shared, a terminal other than the shared terminal, that is, the terminal (the shared entity in FIG. 8) Describe the process.

For example, after sharing is performed between terminals (S31) as shown in FIG. 8 or FIG. 9, a call end button is displayed in a terminal other than a shared terminal, that is, If it is selected, the corresponding termination request is transmitted to the application server 130 through the communication module (S32), and the video call is terminated accordingly. At this time, the calling module of the corresponding terminal whose call termination is selected can call the sharing module through the API to instruct the sharing module to stop its operation. Accordingly, the shared main screen (or the shared screen) and the video call screen disappear, (S33).

Meanwhile, the application server 130 deletes the corresponding terminal selected in the managed conference room from the participant in response to the termination request, and transmits the deletion request to the shared server 140 (S34) The server 140 deletes the corresponding terminal, which is selected in the conference room, from the shared participant, and responds to the application server 130 (S35). Then, the information of the corresponding participant in the corresponding conference room managed by the application server 130 and the shared server 140 is deleted, and only the information on the current valid participants is managed.

FIG. 11 is a flowchart illustrating a method for deleting a conference room at the end of a call by a shared subject according to an exemplary embodiment of the present invention. Referring to FIG.

Here, a process of deleting the corresponding conference room by terminating a video call by a shared terminal, that is, a terminal (the shared subject of FIG. 8) that has issued a sharing request after the sharing between terminals is performed as shown in FIG. 8 or 9 .

8 or FIG. 9 (S41), if a call termination button is selected in the terminal (the share subject in FIG. 8) that generated the sharing request, the corresponding termination request is transmitted to the application Is transmitted to the server 130 (S42), and the video call and sharing are all terminated accordingly. At this time, the call module of the corresponding share subject terminal whose call termination is selected can call the sharing module through the API to instruct the sharing module to stop its operation, whereby the shared main screen (or the shared screen) and the video call screen disappear And can be returned to the desktop (S44).

In response to the termination request, the application server 130 deletes information related to the corresponding conference room to be managed (e.g., identifier of the sharing requestor, participant information, conference room unique key value server access information, etc.) The call termination request for all calls to the video call and the sharing is transmitted (S43). Accordingly, the calling module of the sharing terminals can call the sharing module through the API in response to the received termination request to instruct the sharing module to stop the operation. Thus, the shared main screen (or the shared screen) Disappear and return to the desktop (S44).

On the other hand, in response to the termination request, the application server 130 deletes information related to the conference room as described above, and then transmits a sharing termination request to the sharing server 140 (S45) The application server 130 replies that the sharing is terminated (S46) and deletes the corresponding conference room (S47). Alternatively, the sharing server 140 may delete the corresponding conference room and then reply to the application server 130 that the sharing is terminated.

FIG. 12 is a flowchart illustrating a sharing function termination when a shared subject moves to a shared home according to an exemplary embodiment of the present invention.

Here, as shown in FIG. 8 or 9, when a shared terminal, that is, a terminal that has issued a sharing request (shared principal of FIG. 8) is moved from the screen to the shared home after the sharing is performed, .

For example, after the sharing is performed between terminals (S51) as shown in FIG. 8 or FIG. 9, a button for moving to a shared home through a screen during digital multimedia data sharing in a terminal Upon selection (S52), the screen can be returned to the shared main screen (or home page screen) (S55). The home page screen may include various menus for viewing the multimedia data list provided by the sharing server 140. [

If the button for moving to the shared home is selected as described above, the sharing module of the terminal requests the sharing server 140 to terminate the sharing function (S53), and the sharing server 140 transmits the sharing function All the other party terminals that have been sharing are also held on the sharing module through the sharing module (S54). At this time, the video call state of all the terminals that were serving the sharing function before the sharing function is held may be maintained (refer to FIG. 3). Accordingly, after the sharing is terminated, when a sharing request is made by a terminal in a video call, the terminal becomes a share subject, and sharing between the terminals before the above termination can be performed again.

FIG. 13 is a flowchart illustrating the deletion of a conference room at the end of sharing of a shared subject according to an embodiment of the present invention.

Here, a process of deleting the corresponding conference room by terminating sharing by a shared terminal, that is, a terminal (a shared subject of FIG. 8) that has issued a sharing request after sharing is performed as shown in FIG. 4 or 5 will be described.

For example, after sharing is performed between terminals (S61) as shown in FIG. 4 or 5, if a sharing end button is selected in a terminal (sharing subject in FIG. 4) And then transmitted to the sharing server 140 (S52). Accordingly, only the corresponding video call is maintained and sharing is ended, and information related to the corresponding conference room for sharing is deleted.

The sharing server 140 delivers the corresponding sharing termination request to the application server 130 according to the sharing termination request as described above and transmits the corresponding conference room where the application server 130 is managed (for example, the identifier of the sharing requester, The inherent key value server connection information, etc.) (S65), and the shared server 140 itself also controls the deletion of information related to the corresponding conference room (e.g., identifier of the sharing requestor, participant information, Information is deleted (S69).

Meanwhile, the sharing server 140 transmits a termination request for all calls to the sharing to all other sharing terminals (S64). In response to the termination request, the sharing module of the sharing terminals calls the calling module through the API to switch to the video call screen so that the video call screen is displayed on the screen (S68).

Upon receiving a response to the selection of the sharing end button from the sharing server 140 (S66), the terminal that has transmitted the sharing termination request through the sharing module (the sharing subject who has issued the sharing request) The call module is called through the API to switch to the video call screen so that the video call screen is displayed on the screen (S68).

Herein, since the information related to the conference room (for example, the identifier of the sharing requestor, the participant information, the meeting room unique key value server access information, etc.) is deleted, the sharing function can be activated again through a sharing request by a terminal in video communication 8).

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
