System and method for sharing web-based services during conversations {SYSTEM AND METHOD OF SHARING WEB-BASED SERVICE DURING CONVERSATION}

The present invention relates to a system and method for sharing a web-based service during a conversation using terminal devices, and to a system and a method for easily using a service provided in a web manner during a conversation with a counterpart.

In the desktop computer, there were many functions to share the screen with other computers in the remote area, but at the same time, the voice call often used a separate ordinary phone, which caused inconvenience of connecting and sharing the screen.

Although technologies such as Voice over Internet Protocol (VoIP) can be used to provide screen sharing and voice calls by a computer, there is an inconvenience of using an existing phone number and a separate ID.

In addition, there are cases where voice / text chat is provided with a game counterpart within a specific application such as an online game on a desktop or a smartphone. However, in the case of a smartphone, there is a problem that information sharing or function interworking between applications is limited due to security problems. In other words, if one application starts a voice / text chat and then wants to use a different application with the other party, the voice / text chat must be terminated.

Recently, terminals capable of displaying a web page, such as a desktop computer or a smart phone, have a function of displaying the same web page by sharing a web browser with another terminal located at a remote location.

Since the web browser is very complicated software, the OS (iOS, Android, etc.) of the terminal device uses the web view component provided in the form of UI component (UIWebView for iOS, WebView class for Android. It is preferable. Since the application can intercept an attempt to open a new URL in the web view component, and the UI can be obtained by sending this URL to another terminal device to display the same page, but the information and functions provided by the web view component to the application are limited. Therefore, it is not easy to synchronize the browsers of the two terminal devices.

In particular, the application cannot access or change the UI history of the web view component, and it is difficult to distinguish between the URL opened by the user and the automatic redirection of one web page to another.

If the web page of the link clicked by the user is redirected, if the user wants to synchronize by simply sending a UAL that is opened to another terminal device, both terminal devices may have different history when the web page to be loaded is automatically redirected. Precise synchronization is not possible.

The first terminal device according to an embodiment of the present invention includes a chat service provider for providing a chat service with a second terminal device, and a first web page displayed using a first UAL while providing the chat service. And a web browser synchronization processing unit for controlling the second web page displayed on the web browser of the second terminal device to be synchronized, wherein the web browser synchronization processing unit is configured to determine whether the first UAL is redirected. It may be reflected in the synchronization of the first web page and the second web page.

A first terminal device according to an embodiment of the present invention is a chat service providing unit for providing a chat service with a second terminal device, a user receiving a control signal for playing first multimedia content while providing the chat service. The first terminal is extracted from the interface and the input control signal, which is the address where the first multimedia content is stored, and the first terminal is transmitted to the second terminal device so that the second terminal device transmits the second multimedia device. It may include a multimedia content synchronization processor for controlling to display the content.

In a method of operating a first terminal device according to an embodiment of the present invention, a method of providing a chat service with a second terminal device in a chat service provider and a web browser synchronization processor, during the provision of the chat service, include: And controlling the first web page displayed using the UAL and the second web page displayed in the web browser of the second terminal device to be synchronized, and wherein the web browser synchronization processing unit is configured to redirect the first UAL. It may be determined whether it is a UAL and reflected in the synchronization of the first web page and the second web page.

In a method of operating a first terminal device according to an embodiment of the present invention, in the chat service providing unit, providing a chat service with a second terminal device, in a user interface, during the providing of the chat service, the first multimedia content is provided. Receiving a control signal for playing the reproduction, and the multimedia content synchronization processing unit, from the input control signal, extracts a first UAL which is the address where the first multimedia content is stored, and the extracted first UEL Transmitting to the second terminal device to control the second terminal device to display the second multimedia content.

According to the present invention, a smartphone having both a voice call and a general computing function can use the same web service or enjoy a game, music, video, etc. while simultaneously having a voice call or a text chat form with another person.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The terminologies used herein are terms used to properly represent preferred embodiments of the present invention, which may vary depending on the user, the intent of the operator, or the practice of the field to which the present invention belongs. Therefore, the definitions of the terms should be made based on the contents throughout the specification. Like reference symbols in the drawings denote like elements.

1 is a diagram illustrating a system 100 for sharing a web-based service during a conversation between terminal devices according to an embodiment of the present invention.

The terminal devices 130 and 140 described in the present specification may be interpreted as a device having a communication function, a screen input / output function, and a web browser, such as a smartphone and a tablet.

In addition, the components included in the terminal devices 130 and 140 may be downloaded and installed as independent applications or may be included in the manufacturing step.

The terminal devices 130 and 140 upload and register the phone number list of the phone book together with the phone number of the terminal device to the call server 110. The call server 110 returns a list of numbers corresponding to a registered user among the list of phone numbers uploaded by each terminal device 130 or 140 to each terminal device 130 or 140. As a result, the user of each terminal can check which number of his or her telephone number list can use the service provided by the present invention together.

When the user selects one number, the terminal devices 130 and 140 call the terminal device of the selected number. In this case, the telephone may be a conventional public switched telephone network (PSTN) type general telephone or a packet type telephone (VoIP) provided by the call server or a third server.

The two terminal devices 130 and 140 that are in conversation with each other request a web page, music, and video from a content server while having a voice call or text chat, and browse the web pages together, listen to music together, or watch a video together. Can be.

Hereinafter, the present invention will be described through an embodiment in which two terminal devices 130 and 140 perform a voice call type conversation.

As a specific example, the first terminal device 130 includes a screen 131 for displaying a web page, a web browser synchronization processor 132, and a chat service provider 133 to synchronize the displayed web page. can do.

The conversation service provider 133 may provide a voice call and a text chat service, and may include at least one of a media player, a phone book, and a call module.

Similarly, the second terminal device 140 may include a screen 141 for displaying a web page, a web browser synchronization processor 142, and a chat service provider 143 to synchronize the displayed web page. have.

The web browser synchronization processing unit 132 or 142 may synchronize web pages displayed on the first terminal device 130 and the second terminal device 140.

After the two terminal devices 130 and 140 are connected to communicate with each other, the web browser synchronization processing unit 132 and the web browser synchronization processing unit 142 are configured in web page units for the web browsers of the two terminal devices 130 and 140. You can synchronize with each other.

That is, when a user enters a new UAL in a web browser of the first terminal device 130, clicks a link to another website, or presses a back button, information about this behavior is displayed in the web browser of the second terminal device. In this case, the web browsers of the two terminal devices 130 and 140 may display the same web page.

This feature is provided in both directions. In other words, both users of both terminal devices 130 and 140 can open a new page and this can be reflected in other terminal devices.

In other words, during the provision of the chat service through the chat service provider 133, the web browser synchronization processor 132 may display the first web page displayed on the first terminal device 130 using the first UAL and the second. The second web page displayed in the web browser of the terminal device 140 may be controlled to be synchronized.

In this case, the web browser synchronization processing unit 132 may determine whether the first UAL is a redirected UAL and reflect the synchronization of the first web page and the second web page.

More specifically, the web browser synchronization processing unit 132 transmits the first UAL used for loading the first web page to the second terminal device 140, so that the web browser of the second terminal device 140 is Control to load a second web page identified as the first UEL.

At this time, the web browser synchronization processing unit 132 checks whether the first UAL is a redirected UAL, and if the redirected UAL does not transmit to the second terminal device 140, the second terminal only if the redirected UAL is not. It may be transmitted to the terminal device 140.

In other words, the web browser synchronization processing unit 132 generates the first UAL only when the first UAL is generated by the user's control, for example, when an event such as a UAL input, a link click, or a back click occurs. May be transmitted to the second terminal device 140.

For example, the web browser synchronization processor 132 may use the user input variable value to determine whether the first UAL is a UAL generated by a user's control or a UAL generated by a redirect.

The web browser synchronization processor 132 may check an input signal generated from a user interface, and set a user input variable value to a true value when the first UAL is generated by the input signal.

Accordingly, the web browser synchronization processing unit 132 may check the user input variable value and determine that the user input variable is a UAL generated by the user's control when it is set to a true value, and transmit the first UAL to the second terminal device. have.

On the contrary, the web browser synchronization processing unit 132 checks the value of the user input variable and determines that the UEL is generated by the user's control when the value of the user input variable is not set to a true value. 1 Do not send UAL.

More specifically, when the user clicks on the 'http://www.company.com' link shown by the web view component in the first terminal device 130, the web browser synchronization processing unit of the first terminal device 130 is provided. 132 intercepts the 'www.company.com' address and sends it directly to the second terminal device, and the web view component of the first terminal device 130 continues to load the 'www.company.com' page.

At this time, the 'www.company.com' web page opened by the web view component of the first terminal device 130 may be automatically redirected to the 'company.com/index.jsp' page.

Therefore, the first terminal device 130 loads the 'company.com/index.jsp' page by automatic redirection. In addition, the web browser synchronization processing unit 132 of the first terminal device 130 loads the new web page of 'company.com/index.jsp' as the second terminal device ( 140 may determine whether to transmit.

The web browser synchronization processor 132 confirms that the web page of 'company.com/index.jsp' is a page loaded by a redirection rather than a user's control, and does not transmit it to the second terminal device 140.

As a result, the first terminal device 130 and the second terminal device 140 may open the web page of 'www.company.com' in the same way and may be redirected to the 'company.com/index.jsp' page again. have.

To implement this, the web browser synchronization processing unit 132 designates a user input variable value as a true value when the user touches the screen of the web view component or the user inputs a new UAL, and the web view component opens a new UAL. In this case, if the user input variable value is true, the UAL can be transmitted to the counterpart and the user input variable value can be set as a pulse again.

That is, if the page is redirected when the page of the new URL is loaded, the web browser synchronization processor 132 executes loading of the new page without transmitting the URL to the counterpart so that the opposite web view component loads the same page twice. You can solve the problem.

In addition, the first terminal device according to an embodiment of the present invention is a loading indicator display unit (not shown) for displaying the loading status of the first web page is currently loading, and the second web page is being loaded in the second terminal device 140 ) May be further included.

The loading indicator display unit may separately display a case in which both the first web page and the second web page are being loaded, only the second web page is being loaded, and only the first web page is being loaded.

Since the web browser usually takes a few seconds or more to load a web page, the first terminal device 130 may display a "progress bar", an animated icon, or the like through the loading indicator display. The same "loading indicator" can be displayed.

In the present invention, although the two terminal devices 130 and 140 respectively load the same web page, the time required for the web page to be loaded may vary according to the network speed of the region where the terminal is located. In order for a user to talk about the contents of the same web page with the other party in conversation, it is convenient to easily know that the web pages of both terminals 130 and 140 are loaded.

To this end, each of the two terminal devices 130 and 140 may implement a loading indicator by using two bits that can know the loading state of the browser of the self and the counterpart in the following manner.

The loading indicator of the present invention

00: Normal: Invisible or frozen

11: Both browsers are loading

01: Your browser has finished loading but the other browser is loading

10: The opponent's browser has finished loading but his browser is loading

It can be displayed in four states such as to provide the loading state of a web page.

The web browser synchronization processor 132 of the first terminal device 130 according to an embodiment of the present invention enables user discrimination and game event exchange for web game sharing during a conversation.

To this end, the web browser synchronization processing unit 132 according to an embodiment of the present invention sets JavaScript to be executed in the web view component of the second terminal device 140 as an argument of an event delivery API (Application Programming Interface) and delivers the event. The API may be executed to control execution of the game event by transmitting the game event to the second terminal device.

In this case, the web server providing the web game service uses a call session ID and a terminal identification ID stored in a cookie by the first terminal 130 and the second terminal 140 using the chat service. To determine the identity in the game.

More specifically, unlike a web page, a game service cannot be shared simply by viewing the same content, but it is necessary to show some or completely different screens to two people playing a game, or to transmit each user's input or manipulation to the other party. .

In order to implement such a function, a web server or a web page implementing a web game recognizes two users connected by a conversation through a web browser synchronization processing unit 132 according to an embodiment of the present invention, and is connected to each other during the game. Must be able to exchange their inputs or manipulations, ie game events. In the present invention, the following method is used to share a web game with a conversation.

The call server (web server) assigns a call session ID for identifying an individual conversation and a conversation participant and transmits it to the terminal devices 130 and 140. The call session ID is the same value for the two terminal devices 130 and 140 talking to each other.

The terminal devices 130 and 140 in the conversation store the call session ID and the terminal identification ID of themselves and the other party as cookie values of the web view component so that they can be read by the web page or the web server. The terminal identification ID is an identifier for identifying an individual terminal device and may use a user ID assigned by a system or a device ID uniquely assigned by a terminal manufacturer. The terminal identification ID of the other party is obtained by exchanging the terminal identification ID in the call connection process.

The web page or web server reads the call session ID stored in the cookie of the web view component and the terminal identification ID values of itself and the other party, and knows that two talkers are playing the game together. identity) and the identity of the other party participating in the game can be determined through the other party's terminal identification ID.

In the present invention, the object of delivering a game event is to execute arbitrary JavaScript on the web view component of the counterpart, which can be implemented through a JavaScript API for delivering an event.

For example, when two players play a concave game and use a white stone to place a stone at a specific location, the internal process is as follows.

The event propagation API is executed in the webview component of the participant who placed the stone, and the JavaScript function name and coordinate values to be executed in the opposing webview component as game events are arguments of the event propagation API. (For example, "open (remote: // put_stone (10,10));"

In the web view component, a game event to be delivered to the web browser component is transmitted to the web browser synchronization processor 132 according to an embodiment of the present invention, and the game event is transmitted from the web browser synchronization processor 132 to the web browser synchronization processor 142 of the counterpart. Is transmitted, and the web browser synchronization processor 142 of the other party executes the JavaScript delivered as the game event delivered to the web view component. The JavaScript is part of a pre-written program, and it can handle the display of stones placed on the screen by using the transmitted coordinate values, for example, the concave.

Therefore, according to the present invention, a smartphone having both a voice call and a general-purpose computing function can simultaneously use the same web service or enjoy games, music, videos, etc. while having a voice call or a text chat form with another person. have.

According to the present invention, a phone number entered in a phone book of a smartphone can be used to communicate with a counterpart, and a general mobile web page can be browsed together or a web-based application can be used together.

2 is a diagram illustrating a web browser synchronization processing unit 200 according to an embodiment of the present invention.

The web browser synchronization processing unit 200 according to an embodiment of the present invention uses the feature information extraction unit 210, the feature information transmission / reception unit 220, and the equality determination unit 230 to more accurately synchronize a web page. Can be.

Even if the web browsers of the first terminal device and the second terminal device open the same UAL, different web pages may be loaded according to the cookie value of the web browser, or contents may be randomly generated to load different web pages.

For example, a web page that requires a login can display different web pages depending on the logged in user. In this case, the web browser informs the user that the web pages that are shared are not identical to each other, and maintains the web page identity by returning to the same web page before.

To this end, the feature information extractor 210 may extract first feature information of the loaded first web page. That is, when the loading of the newly opened web page is completed, the feature information extracting unit 210 extracts feature information of the loaded web page.

In addition, the feature information transceiver 220 may transmit the first feature information to the second terminal device, or receive second feature information about the second web page from the second terminal device.

At this time, the feature information transceiver 220 may store the extracted feature information in its own memory, and when the feature information is not transmitted from the other party, may wait until the feature information is delivered.

Next, the equality determination unit 230 may determine whether the first web page and the second web page are the same by comparing the extracted first feature information with the received second feature information. .

In this case, the first feature information includes at least one of the size or screen size of the HTML file constituting the first web page, the second feature information is the size of the HTML file constituting the second web page Or information of the same type as the first feature information in the screen size.

When the two web pages are not the same, the web browser synchronization processing unit 200 according to an embodiment of the present invention may inform the user of this as a UI and automatically return to the same web page again before.

In detail, the sameness determination unit 230 may determine whether the two web pages are the same, and if it is not the same, display a popup that says "It is a web page that cannot be shared" to indicate that they are not the same. .

As a result of the determination, when the first web page and the second web page are not the same, the web browser synchronization processing unit 200 according to an embodiment of the present invention uses the first web page and the second web page. Finally, you can synchronize using the URLs of web pages that were determined to be the same.

To this end, the web browser synchronization processing unit 200 according to an embodiment of the present invention may record the UAL of the web page determined to be the same.

The first terminal device according to an embodiment of the present invention enables media sharing by synchronizing playback of music and video during a conversation. This will be described in detail with reference to FIG. 3.

3 is a block diagram illustrating an internal configuration of a first terminal device 300 according to an embodiment of the present invention.

The first terminal device 300 according to an embodiment of the present invention may include a chat service providing unit 310, a user interface 320, and a multimedia content synchronization processing unit 330.

First, the chat service provider 310 may provide a chat service with the second terminal device.

The user interface 320 may receive a control signal for playing the first multimedia content while providing the chat service.

The multimedia content synchronization processing unit 330 extracts a first UAL, which is an address where the first multimedia content is stored, from the input control signal, and transmits the extracted first UEL to the second terminal device. The device may be controlled to display the second multimedia content.

In addition to browsing web pages, two terminal devices in conversation may request music or video, and use the following method for synchronizing music or video played in a media player.

When the user clicks the play button of the media player component in the first terminal device through the user interface 320, the multimedia content synchronization processor 330 of the first terminal device may select an address of a music or video to be played by the media player component. The first terminal device may transmit a loading completion message to the other party when the music or video is loaded and loaded through the multimedia content synchronization processor 330.

The multimedia content synchronization processor of the second terminal device transmits the address of the music or video to the media player component, and when the loading of the music or video is completed, a loading completion message may be delivered to the other party.

The multimedia content synchronization processing units of the first terminal device and the second terminal device may start playing the media when their media loading is completed and the loading completion message is received from the other party.

The multimedia content synchronization processing units of the first terminal device and the second terminal device transmit a playback stop message to the other party when the media content is paused due to the network speed or is paused or stopped by a user's operation. You can stop playback.

The multimedia content synchronization processing units of the first terminal device and the second terminal device may change from the play state to the pause state or the stop state when receiving the reproduction stop message from each other.

When the multimedia content synchronization processing units of the first terminal device and the second terminal device become paused due to their network speed, the multimedia content synchronization processing units may send a playback start message to the other party and start playback.

The multimedia content synchronization processing units of the first terminal device and the second terminal device may start playback when they receive a playback start message from the other party when the network device is paused due to a network speed of the other terminal device.

The first terminal device according to an embodiment of the present invention may further include a loading indicator display unit (not shown) for displaying a loading and buffering state of music and video when sharing media during a conversation.

The first terminal device according to an embodiment of the present invention may display a loading state of the first multimedia content being loaded and the second multimedia content being loaded by the second terminal device through a loading indicator display unit (not shown). .

Specifically, since the media player needs to load media data of several seconds or more into the playback buffer in order to play music or video media, and it takes several seconds or more for this, the first terminal device according to an embodiment of the present invention may be a user. Can display a "loading indicator" such as a "progress bar" or an animated icon.

In addition, if the network speed temporarily slows down during media playback, media data to be played in the playback buffer may not yet arrive, and playback must be paused while the playback buffer is filled. In the present invention, although the two terminal devices each load the same media, there may be a large difference in the time taken for the media to be loaded depending on the network speed of the region where each terminal is located.

A media player of two terminal devices starts playing at about the same time so that a user can talk while watching the same media with the other party. There are two methods for implementing a loading indicator for knowing the loading and buffering states of the media players of two terminal devices. The first method is to display the loading indicators without distinguishing the media players of the two terminal devices.

The loading indicator display portion of the present invention

0: Normal: Invisible or frozen

1: You or your opponent is loading or buffering

The loading status can be indicated by using two different bit values such as.

The second method of implementing a loading indicator when playing media during a conversation is to display the media player loading or buffering status of the two terminal devices in a manner of determining whether the network speed is slow when playback stops frequently due to network speed. This is a method of giving a hint to change the network of a slow counterpart's terminal device or to attempt a conversation with another counterpart.

The media loading indicator of the present invention

00: Normal: Invisible or frozen

11: Both media players are loading or buffering

01: Your media player has finished loading or buffering but the other media player is loading or buffering

10: The other media player has finished loading or buffering but its media player is loading or buffering

The loading status can be indicated by using four different bit values such as.

The first terminal device according to an embodiment of the present invention can drive a synchronized media player when playing music or video from a web page for media sharing during a conversation.

The multimedia content synchronization processor according to an embodiment of the present invention extracts and transmits the information of the first multimedia content played by the first terminal device using the player, and the second terminal device uses the player. Control to play the second multimedia content.

To this end, the multimedia content synchronization processor according to an embodiment of the present invention defines a unique UL scheme for the player that plays the first multimedia content, and when the control signal is input, confirms the defined UL scheme The first multimedia content may be played through the player.

When playing music or video from a web page, the synchronized media player according to the present invention may not be driven, but a default media player designated by the OS of the terminal device may be driven, and the users in conversation may use the synchronized media playback function. It becomes impossible.

Specifically, the multimedia content synchronization processor according to an embodiment of the present invention defines a unique URL scheme for playing media using a media player synchronized from a web view component and newly opens a web view component in an application. If the UAL is intercepted and the UAL scheme corresponds to the UAL scheme, instead of sending the UAL request, the synchronized media player is driven to play the media.

When the loading of the web page in the web view component is completed, the contents of the web page are inspected, and when the media URL is found, the media view is changed to the unique URL. If the user selects media playback, a request for the unique UAL is generated instead of the original media UAL, so that synchronized media playback can be started.

Whether the media URL is included or not is determined by reading the Document Object Model (DOM) of the web page loaded in the web view component in the application. The change of the media URL is injected by injecting JavaScript that modifies the DOM of the loaded web page. Can be.

In the present invention, synchronized media playback from a web page may be performed in the following order.

When the web page request is initiated by the user's operation, the multimedia content synchronization processor according to an embodiment of the present invention intercepts the corresponding URLs and compares the media contents to the original media playback, and proceeds to play the media when the media playback is the original URL. If it is not a unique media playback UAL, proceed to load the web page.

The multimedia content synchronization processor drives the synchronized media player and delivers a unique UAL.

In addition, the multimedia content synchronization processor loads a new web page in the web view component and, upon completion of the loading, examines the contents of the web page, and if a media URL is found, the multimedia content synchronization processor replaces the media URL with a unique URL.

4 is a flowchart illustrating an operation method for sharing a web-based service in a first terminal device according to an embodiment of the present invention.

In a method of operating a first terminal device according to an embodiment of the present invention, the chat service provider may provide a chat service with the second terminal device (step 401).

In addition, the operating method of the first terminal device according to an embodiment of the present invention, the web browser synchronization processing unit of the first web page and the second terminal device displayed using the first UAL during the provision of the chat service; The second web page displayed in the web browser may be controlled to be synchronized.

In this case, the web browser synchronization processor may determine whether the first URL is a redirected URL and may reflect the synchronization of the first web page and the second web page.

Specifically, the method of operating the first terminal device according to an embodiment of the present invention to check the input signal generated in the user interface, through the web browser synchronization processing unit, in order to control to be synchronized, by the input signal When the first UAL occurs, set the user input variable value to a true value, check the user input variable value, and set the first UEL to the second terminal device when the user input variable value is set to a true value. Can transmit

According to an embodiment of the present invention, a method of operating a first terminal device may include loading the second web page, loading both the first web page and the second web page through a loading indicator display unit, and The loading status may be displayed by distinguishing the case where only the first web page is being loaded.

In addition, the operating method of the first terminal device according to an embodiment of the present invention may use two bits that can know the loading state of the browser of the self and the other party in the same manner as in FIG.

Referring to FIG. 5, when loading of a web page is started by a user's manipulation (step 501), the first terminal device according to an embodiment of the present invention transmits a web page address to the second terminal device (step 502). The state value of the loading indicator is set to 11 (step 503).

If, on the other hand, that is, the web page loading is started by the message from the second terminal device (step 504), the first terminal device according to an embodiment of the present invention does not transmit the web page address to the second terminal device. Immediately set the status value of the loading indicator to 11 (step 503).

Accordingly, the first terminal device according to an embodiment of the present invention determines whether the loading of the web page is completed (step 505), and the other party, that is, the second terminal device determines whether the loading of the web page is completed (step 505).
