Mobile terminal that supports video playback on webpages and how to support video playback on webpages {METHOD AND MOBILE PHONE FOR SUPPORTING PLAY MOVING PICTURE IN WEBPAGE}

The present invention relates to a mobile communication terminal that supports video playback on a web page and a video playback support method on a web page. More specifically, since a dedicated application directly calls a video player, the video player can be controlled in various applications. It is possible to provide a dedicated video player for each dedicated application, or to provide a variety of video presentations to the user through options when the video player is running, enabling various application development of the dedicated application. Invention.

With the development of the communication environment, portable devices such as mobile communication terminals have been able to add new and various additional functions. As an example in which the additional function is added, a mobile communication terminal supporting a wireless Internet function may be exemplified according to a strong desire to use the Internet in the mobile communication terminal.

The use of the Internet using the wireless Internet function, that is, the viewing of a web page, has many limitations, such as the characteristics of a wireless communication section and the hardware performance of a mobile communication terminal, compared to the viewing of a web page using a wired internet.

Accordingly, various forms of browsing of web pages have been proposed to avoid the above limitations.

As an example, a web page viewing form has been proposed in which a wireless Internet service is provided to the mobile communication terminal by transmitting the web page as an image to a low performance mobile communication terminal that cannot use the wireless Internet freely. In the web page viewing form of the above example, by receiving a web page requested by the mobile communication terminal from the server at the conversion server, and constructing a screen obtained by parsing / rendering the received web page into an image file, transmitting the result to the mobile communication terminal, The web page of the image is implemented in the mobile communication terminal through a web viewer. In other words, in the web page viewing form of the above example, the conversion server performs parsing of markup tags included in the web page by the mobile communication terminal in consideration of the performance of the mobile communication terminal.

Although the web viewer may bypass the wireless Internet service by visualizing the web page of the received image, the web viewer may visualize only the Internet-related data of the image property, and may support natural resources such as web browsing. There is a limit.

In another form of web page viewing to solve this limitation, by converting the markup tag of the web page in the conversion server suitable for the mobile communication terminal, and reconstructed, parsing / rendering in the mini browser of the mobile communication terminal, Is displayed on the screen. The mini-browser of the mobile communication terminal processes the markup tag converted to be suitable for the mobile communication terminal to enable browsing in the mobile communication terminal.

However, in other forms of web page viewing, the web page may be distorted differently from the original due to the screen being broken while the web page is converted by the conversion server.

In order to improve this problem, another web page reading form has been proposed to have a full browser capable of processing all tags that can be included in a web page in a mobile communication terminal. The full browser may allow a web page expressed in a similar quality to a wired communication network to be implemented in a mobile communication terminal, and also support browsing freely in the mobile communication terminal.

However, it is not technically easy to implement all markup tags using a full browser in a mobile communication terminal having lower hardware specifications than a normal computer. To solve this problem, the hardware of the mobile communication terminal must be upgraded to a high performance specification, but this causes a price increase of the mobile communication terminal.

Recently, in order to solve the above problems, a technology for displaying a specific web page by developing a dedicated application corresponding to a specific web page and executing the dedicated application has been developed.

Dedicated application is designed to show only specific web pages, so unlike conventional browsers, it cannot provide various web pages according to user's input address, but it is faster and has lower hardware specification than ordinary computer. There is an advantage that can improve the service speed provided in a specific web page in the terminal. In order to parse / render a specific web page in a dedicated application, it can be performed by calling an existing browser core. Hereinafter, a process of playing a video included in a conventional web page will be described in FIG. 1, and through this, a method of implementing a video playback faster without changing hardware of a mobile communication terminal will be sought.

1 is a flowchart illustrating a process of playing a video in a mobile communication terminal according to the prior art.

Referring to FIG. 1, the full browser of the mobile communication terminal requests a web page to the server (101), and the server transmits the web page to the full browser according to the request (102). Here, the server may be a web server or a video server for providing the web page.

Thereafter, the full browser delivers 103 the web page to the browser core, and the browser core parses / renders the delivered web page. The full browser presents the web page parsed / rendered by the browser core on the screen (104).

At this time, when the user selects an arbitrary area in the web page, the full browser generates a click event for the selected area (105), and transmits the coordinates (x, y coordinates) where the event occurred to the browser core (106). ). The browser core determines whether the transmitted coordinates are related to the video tag (107). If the determination result is the video tag, the browser core extracts the URL corresponding to the video from the script of the web page (108), and delivers the extracted URL to the video player. (109). Here, the browser core may determine the video tag if the video tag has a video extension such as avi, wmv, asf, asx, mpg, mpeg, etc. in the video address portion of the <object src = "video address">.

The video player may determine whether a video corresponding to the transmitted URL is stored in the mobile communication terminal, and if it is not stored, request the video to the server 110 to receive and play the requested video from the server (111). (112).

As described above, in order to play a video existing in a web page, a browser core that parses and renders a web page is called and handled by a video player.

In this case, when providing a video from a web page displayed through a dedicated application, there is a technical problem such as a collision between applications to apply a conventional browser core that unilaterally calls a video player. Want to do it was a difficult problem to apply.

Since one embodiment of the present invention can call a video player directly for playing a video provided through a specific webpage in a dedicated application. An object of the present invention is to provide a mobile communication terminal that supports video playback on a web page and a video playback support method on a web page that solve technical problems caused by conflicts between applications.

In one embodiment of the present invention, since the dedicated application directly calls the video player, the video player can be controlled in various ways for each dedicated application, and the video player can be provided exclusively for each dedicated application, or an option when the video player is executed. It is possible to provide various ways of providing video to the user, and to provide video playback on mobile communication terminal and web page that support video playback on web page that enables various application development of dedicated application. There is a purpose.

One embodiment of the present invention is to determine whether the means for implementing a web page in the browser core is a dedicated application, to deliver only the network address associated with the video, or to directly call the video player, the conventional general browser and dedicated applications In the mobile terminal mounted at the same time, it is not necessary to provide a separate browser core according to a dedicated application, so that the mobile terminal and the web page that supports video playback on the web page that saves the memory resources of the mobile terminal The purpose is to provide a video playback support method.

In order to achieve the above object, the mobile communication terminal holds a network address of a specific web page in advance, receives a specific web page according to the network address when executed, and executes a key event according to a click input of the display area of the specific web page. And a video player which is called by the dedicated application to generate a video file, and which receives a video file from a server identified by the network address extracted in association with the key event.

In addition, as a technical method for achieving the above object, the video playback support method generates a key event in response to a click input to the display area of the web page received according to a specific web page network address previously held by the dedicated application. Calling a video player, and receiving and playing a video file from a server identified by a network address extracted in association with the key event in the called video player.

According to one embodiment of the present invention, since a dedicated application can directly call a video player for playing a video provided through a specific webpage. Solve technical problems caused by conflicts between applications.

According to an embodiment of the present invention, since the dedicated application directly calls the video player, it is possible to control the video player in various ways for each dedicated application, so that the dedicated video player may be provided for each dedicated application or the video player may be executed. It can provide a variety of videos provided to the user through the city option, etc., enabling a variety of application development of the dedicated application.

According to an embodiment of the present invention, by confirming whether the means for implementing a web page in the browser core is a dedicated application, by passing only the network address associated with the video, or by calling the video player directly, In a mobile communication terminal in which a dedicated application is mounted at the same time, it is not necessary to provide a separate browser core according to the dedicated application, thereby saving the memory resources of the mobile communication terminal.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings and accompanying drawings, but the present invention is not limited to or limited by the embodiments.

As used herein, a mobile communication terminal is a generic term for all portable devices. For example, a computer, a notebook computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a cellular phone ), A PCS (Personal Communication Service) phone, satellite / terrestrial DMB (Digital Multimedia Broadcasting) phone and the like.

2 is a flowchart illustrating a procedure of a video reproducing support method in a web page according to an embodiment of the present invention.

2, the dedicated application of the mobile communication terminal is downloaded and installed through a separate dedicated application providing server (not shown) or is pre-installed in the mobile communication terminal. Dedicated applications have a network address of a specific web page in advance in order to provide a user with a specific service provided by the web page. Dedicated application is a kind of virtual machine (VM) application, but the conventional application simply receives data from the server and displays it, while the dedicated application corresponds to a specific website to receive the website and parse and render the browser core. Interpret and show through.

To do this, the network address of a specific web page is reserved in advance in a dedicated application to show only a specific web page. This is a difference from the conventional browser which can display various web pages by selecting the network address from the conventional user. In addition, the display area or usage logic that is not changed other than the dynamic web page display area can be provided in data included in a dedicated application or in a native language (such as C ++) and implemented as compiled logic, so that it can be provided faster than a general browser.

When a dedicated application is executed by a user's selection among dedicated applications installed in the mobile communication terminal, a specific web page is requested by accessing a network address of a specific web page previously owned by the dedicated application (201). The network address of a specific web page may be composed of a Uniform Resource Lacator (URL) and a web page markup document name of the specific web page.

The server transfers the requested specific web page to the dedicated application of the mobile communication terminal (202). Here, the server may be a web server or a video server that provides the requested specific web page.

Normally, several submenus are included to provide various services to users accessing the homepage of a portal web site. There are URLs for each submenu. For example, if the submenu is composed of 'Search', 'Bulletin', 'Game', 'Blog', 'Photo Album', etc., a dedicated application is preferably developed to correspond to a specific website corresponding to the submenu. Will include the URL corresponding to the submenu as the network address of the particular website.

The dedicated application delivers the web page delivered from the server to the browser core (203).

The browser core parses and renders the delivered web data (204). The browser core parses the web data based on a markup language included in the web data, for example, an HTML tag, and matches the meaning of each HTML tag based on the parsed content. This includes rendering operations that perform screen display. To this end, the browser core of the mobile communication terminal may be provided with a module for performing parsing independently, and a module for rendering.

In general, a web page includes various components in the form of a file. An example of the components includes a CSS file defining a presentation style of a web page, a JavaScript file running at a client end, and an image tag. An image file, a video file included by a video tag, and the like can be exemplified. The web browser reading the web page parses the data of the web page and requests and loads the necessary files (CSS file, XaviScript file, image file, video file, etc.) accordingly. The web data mentioned is a concept that includes all of these web page configuration files. Therefore, the parsing operation includes interpreting a CSS file and a JavaScript file, and the rendering operation includes displaying an image file on the screen. In other words, parsing and rendering in the present embodiment are not used in the sense of being limited only to the processing of the HTML tag itself.

Thereafter, the user can click any display area in the web page, and the dedicated application generates a key event according to the clicked input (205), and generates the generated key event along with the x and y coordinates of the browser. Deliver to core (206).

In this case, the browser core determines whether the tag corresponding to the web page display area corresponding to the transmitted x and y coordinates is related to the video tag (207). If the determination result is related, the URL as a network address associated with the video file is determined. Is extracted (208). That is, the browser core may determine whether the video tag is by analyzing the DOM structure of the web page.

If determined to be a video tag, the browser core may extract a network address associated with the video file. The video tag has a 'video extension' such as avi, wmv, asf, asx, mpg, mpeg, etc., in the video address portion of <object src = "video address">. If this is determined as a video tag, the video address may be extracted as a network address associated with the video file.

The browser core delivers the extracted network address to the dedicated application (209), so that the dedicated application sends the delivered network address to the video player, thereby calling the video player (210). That is, according to the embodiment of the present invention, the browser core and the dedicated application share the network address, so that the dedicated application, not the browser core, may call the video player.

In this case, the dedicated application may call a video player by designating display properties or options for each specific webpage display area where the key event occurs, or may call a video player specific to the dedicated application (in this case, a dedicated application). As such, a separate video player must be installed), so that a user can provide a unique video playback service for each dedicated application more variously than calling the video player unilaterally from the browser core.

The video player receives the transmitted network address, determines whether a video file corresponding to the network address is already stored in the mobile communication terminal, and if it is not stored, the video player provides the video file to the server. The video file is requested (211).

The server identifies the requested video file and delivers the identified video file directly to the video player (212). Accordingly, the video player receives and plays the transferred video file (213).

3 is a flowchart illustrating a procedure of a video reproducing support method in a webpage according to another exemplary embodiment of the present invention.

Prior to the description of FIG. 3, the description from step 301 to step 308 is replaced with the description from step 201 to step 208 of FIG. 2 described above, and is omitted here.

The browser core determines whether to deliver the extracted network address related to the video to the dedicated application or the video player (309). For example, the browser core may determine a subject (dedicated application, or video player) to which the network address is delivered by determining whether the means for generating a key event is the browser-only application.

Since the browser core of the present invention has a logic different from that of a conventional general browser, there is a disadvantage in that a separate browser core must be mounted according to a dedicated application.

In order to solve this disadvantage, according to an embodiment of the present invention, both a general browser and a dedicated application can be applied to one browser core. If the browser core checks the means for generating the key event, and if the means for generating the key event is a conventional general browser, the means for directly invoking the video player and generating the key event is a dedicated application of the present invention. In this case, by passing the network address to the dedicated application, the dedicated application may call the video player.

After the URL is extracted as the network address in step 308, if the means for generating the key event is the dedicated application, the browser core delivers the extracted network address (URL) to the dedicated application (310). In this case, the dedicated application calls the video player while transmitting the delivered network address to the video player (311).

In contrast, when the means for generating the key event is a conventional general browser, the extracted network address is directly transmitted to the video player, and the browser core calls the video player (312).

The video player receives the transmitted network address, determines whether a video file corresponding to the network address is already stored in the mobile communication terminal, and if it is not stored, the video player provides the video file to the server. The video file is requested (313). The server identifies the requested video file and delivers the identified video file directly to the video player (314). Accordingly, the video player receives and plays the delivered video file (315). 4 is a block diagram illustrating a configuration of a mobile communication terminal that supports video playback in a web page according to an embodiment of the present invention.

Referring to FIG. 4, the mobile communication terminal 400 supporting video playback in a web page according to an embodiment of the present invention includes a browser core 410, a parser 411, a determination module 412, and a dedicated application. 420, and a video player 430.

Dedicated application 420 is an application that holds a network address of a specific web page in advance in order to provide a user with a specific service provided by the corresponding specific web page, it is downloaded through a separate dedicated application providing server (not shown) It can be installed in the mobile communication terminal. For example, when the user selects and executes one of the dedicated applications installed in the mobile communication terminal, the web page may be requested to the server 440 of the network address of the specific web page included in the dedicated application.

The server 440 may deliver the web data for composing the web page to the dedicated application 420. In the drawing, the server 440 is designated as one, but according to an embodiment, the server 440 may be any one of a plurality of servers providing a web page requested by the user. In addition, the web data may include a video tag associated with the video.

The dedicated application 420 delivers the web page delivered from the server 440 to the browser core 410, where the delivered web page refers to web data constituting the web page.

The parser 411 of the browser core 410 parses and parses the web data based on the HTML tag included in the transmitted web data, and the renderer (not shown) parses the parsed content. Based on this, the rendering operation that performs the display corresponding to the meaning of each HTML tag is performed.

The parser 411 analyzes a CSS file and a JavaScript file that define a presentation style of a web page, and the renderer performs a task of displaying an image file on the screen.

Then, when the user clicks on the display area of the displayed web page, the dedicated application 420 generates a key event according to the clicked input, and the x and y coordinates, which are coordinate values that generate the generated key event, are generated. Along with the browser core 410.

In this case, the determination module 412 of the browser core 410 determines whether the tag corresponding to the display area of the web page corresponding to the transmitted x and y coordinates is related to the video tag. Extract the relevant URL. That is, the parsing unit 411 interprets the DOM structure of the web page, and the determination module 412 determines whether the video tag is linked with the occurrence of the key event. The core can extract the network address associated with the video file. In this case, the determination module 412 is a video player, especially if there is a 'video extension' such as avi, wmv, asf, asx, mpg, mpeg in the video address portion of the <object src = "video address">. If there is a video extension that can be played in, it may be determined as a video tag, and the video address may be extracted as a network address associated with the video file.

The browser core 410 determines whether the means for generating the key event is the dedicated application 420, and determines whether to deliver the extracted network address to the dedicated application 420 or the video player 430. Can be. That is, when the means for generating the key event is a conventional general browser, the browser core 410 may transfer the extracted network address to the video player 430 and directly call the video player 430.

However, when the means for generating the key event is the dedicated application 420 of the present invention, the browser core 410 transfers the extracted network address to the dedicated application 420, whereby the dedicated application 420 is delivered. The network address is transmitted to the video player 430 so that the video player 430 can be called. That is, according to the embodiment of the present invention, the browser core 410 and the dedicated application 420 share the network address, so that the dedicated application 420, rather than the browser core 410, controls the video player 430. To be called.

That is, in FIG. 4, the video player 430 is represented as one, but the video player 430 may be multiple according to a dedicated application or a video file.

Accordingly, the video player 430 receives the forwarded network address, determines whether a video file corresponding to the network address is already stored in the mobile communication terminal 400, and if the result is not stored, The server 440, which provides a video file, requests the video file. The server 440 identifies the requested video file and delivers it directly to the video player 430.

The video player 430 receives and plays the delivered video file.

Further, embodiments of the present invention include a computer readable medium having program instructions for performing various computer implemented operations. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination. Program instructions recorded on 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 those having skill in the computer software arts.
