The present invention relates to a method and a system for providing a video file by enabling a video file to be easily played using the video URL in a mobile internet browser.

BACKGROUND With the development of communication technology, mobile terminals such as mobile phones and personal digital assistants (PDAs) are widely used. Accordingly, through such a mobile terminal, a user can make a video call, operate an installed digital camera to capture an image, play a music file, watch satellite / terrestrial DMB broadcasting, Various functions such as playing an embedded game can be conveniently used.

In addition, as third-generation mobile communication services such as WiBro, WCDMA, and HSDPA are commercially available, more and more people use wireless Internet services through mobile terminals. In addition, more and more users are accessing the video UCC website through a mobile internet browser mounted on the mobile terminal and watching video files.

Meanwhile, most video UCC websites now use a player based on Flash. Unlike regular web browsers, mobile Internet browsers do not have a codec for playing Flash-based players, so mobile Internet browsers download Flash video players, or SWF (ShockWave Flash) files, The location of the video file, that is, the video URL, is extracted and sent to the video conversion server. The video conversion server downloads the video file from the web server, converts the video to fit the size and codec of the mobile terminal, and provides it to the mobile internet browser. The mobile internet browser loads a dedicated video player and converts the video to the video conversion server. The transferred video file can be displayed to the user.

In this way, the current problem is in extracting the video URL from the mobile internet browser. In the context of mobile Internet browsers, Flash now supports version 8 (ie ActionScript 2.0). As a result, mobile internet browsers cannot interpret Flash movie files (swfs) written in Flash 9 (i.e. ActionScript 3.0) and therefore cannot extract video URLs. There is a problem that can not watch the video posted on the site.

The present invention has been made to solve the above problems, and when the script language included in the first flash file requested by the mobile internet browser is not implemented in the mobile internet browser, the first flash file is executed on the server during web acceleration. By extracting the video URL and providing the extracted video URL to the mobile Internet browser, it is an object of the present invention to provide a video file providing method and system that can easily play the video file using the video URL in the mobile Internet browser.

In addition, when the first flash file written in the script language of the non-interpretable version of the script language is requested in the mobile internet browser, the present invention executes the first flash file on the server to extract the video URL and extracts the extracted video URL from the mobile internet browser. Providing a method and system for providing a video file by providing a second flash file written in a scriptable language of the interpretable version so that the mobile internet browser can play the video file regardless of the version of the script language in which the flash file was created. The purpose.

In addition, the present invention stores the video URL extracted from the first flash file, the extracted time and expiration time in the database corresponding to the first flash file, and then retrieves and retrieves the flash file requested by the mobile Internet browser from the database If so, it is an object of the present invention to provide a video file providing method and system that can easily extract a video URL stored corresponding to the flash file from a database without executing the flash file.

In order to achieve the above object of the present invention, a video file providing method according to an embodiment of the present invention comprises the steps of downloading a first flash file requested from a mobile Internet browser from a web server, and the downloaded first flash Identifying a script language associated with the file, determining if the identified script language is feasible in the mobile internet browser, and if determining that it is not feasible, extracting a video URL from the first flash file And providing the extracted video URL to the mobile internet browser.

In addition, the video file providing system according to an embodiment of the present invention, the downloading means for downloading the first flash file requested from the mobile Internet browser from the web server, and identify the script language associated with the downloaded first flash file, An address extracting means for extracting a video URL from the first flash file, and determining whether the identified script language is possible to implement in the mobile internet browser, and the extracted video URL. And data providing means for providing the mobile Internet browser.

According to the present invention, if the script language included in the first flash file requested by the mobile internet browser is not feasible in the mobile internet browser, the web flash server executes the first flash file to extract the video URL and then loads the video URL into the mobile internet browser. By providing the extracted video URL, it is possible to easily play the video file using the video URL in the mobile Internet browser.

According to the present invention, when a first flash file written in a script language of an uninterpretable version is requested in a mobile internet browser, a web URL is executed by a server during web acceleration to extract a video URL and extract the video URL into a mobile internet browser. By providing the second flash file written in the script language of the interpretable version of the scripted video URL, the mobile Internet browser can play the video file regardless of the version of the script language in which the flash file is created.

Further, according to the present invention, by storing the video URL extracted from the first flash file, the extracted time and expiration time in a database corresponding to the first flash file, thereafter, the flash file requested by the mobile Internet browser in the database When searching and searching, it is possible to simply extract the video URL stored corresponding to the flash file from the database without executing the flash file.

Hereinafter, a method and a system for providing a video file according to the present invention will be described in detail with reference to the accompanying drawings.

The Flash file is a multimedia software-based file developed by Adobe. It is mainly used for animation, advertisement, game, and video player.

ActionScript is a scripting language that can be interpreted in Adobe Flash Player, and Flash 9 is released with ActionScript 3.0 as of 2008.

The video file providing system 100 according to an embodiment of the present invention may include a web accelerator server 110 and a video conversion server 120.

The web accelerator server 110 downloads the first flash file requested by the mobile internet browser 130 from the web server 140 to identify a script language associated with the first flash file, and the identified script language is the mobile internet. You can determine if it can be implemented in a browser.

For example, when the written version of the identified script language is 2.0, the web accelerator server 110 may determine that the mobile internet browser 130 may be implemented, and when the written version of the identified script language is 3.0. In this case, it may be determined that the mobile internet browser 130 is not implemented.

If it is determined that it is impossible to implement, the web accelerator server 110 may extract the location of the video file, that is, the video URL, to be actually played from the first flash file, and provide the extracted video URL to the mobile internet browser 130. have. For example, the web accelerator server 110 may execute a first flash file to capture a video URL of an actual video file requested by the first flash file, and store a valid video URL corresponding to the first flash file in a database. If so, the video URL may be extracted from the database.

In addition, the web accelerator server 110 checks the version of the script language supported by the mobile Internet browser 130 from a version list prepared in advance, and writes the extracted video URL in the script language of the checked version to generate a second flash. A file may be generated and the generated second flash file may be provided to the mobile internet browser 130. Accordingly, the video file can be easily played using the video URL in the mobile Internet browser.

That is, the mobile Internet browser 130 transmits the video URL to the video conversion server 120 according to the playback command for the provided second flash file, and the video file identified by the video URL in the video conversion server 120. The mobile terminal user by receiving from the web server 140, converting to match the playback environment in the mobile Internet browser 130, and providing the converted video file to the mobile Internet browser 130 in response to the playback command, Will be able to watch the video file posted on the video UCC website as a stream.

2 is a diagram illustrating a configuration of a video file providing system according to an exemplary embodiment of the present invention.

The video file providing system according to an embodiment of the present invention may be configured to include a download means 210, an address extraction means 220, a database 230, a data providing means 240 and a video conversion server 250. have.

The download means 210 functions to download the first flash file requested from the mobile internet browser from the web server.

The first flash file may include an address in which a video file to be actually played is located in a script language. For example, the first flash file may be a swf (shockwave flash) file format, and the swf file may include an URL of an flv file, which is a video file to be actually reproduced, in ActionScript.

In this case, when a connection to the website including the SWF file is requested, the downloading means 210 may determine that the first flash file is requested from the mobile internet browser, and the web server may store the requested first flash file. You can download it from

That is, the video file providing system according to an embodiment of the present invention may record the URL of the video UCC website of 'Pandora TV, M & Cast, M-Gun, etc.' in a table in advance, and the download means 210 may use the mobile Internet. When the identification information of the website requested to be accessed from the browser is recorded in the table, the mobile internet browser may determine that the first flash file is requested, and download the requested first flash file from the web server.

The address extracting means 220 identifies the script language associated with the downloaded first flash file, determines whether the identified script language is possible to implement in the mobile Internet browser, and determines that the implementation is impossible. It extracts a video URL from the first flash file.

In one example, the address extracting means 220 confirms the written version of the script language, and if the checked written version is not retrieved from the version list regarding the version of the script language supported by the mobile Internet browser, it is impossible to implement. You can judge. That is, the version list includes a version of the script language supported by the mobile internet browser 'ActionScript 1.0, ActionScript 2.0', and if the written version of the script language associated with the first Flash file is determined to be 'ActionScript 3.0', the address extracting means 220 may determine that the implementation is impossible and extract a video URL from the first flash file.

The database 230 may store the video URL extracted from the flash file requested by the mobile internet browser and the flash file so as to correlate with the time at which the video URL is extracted.

That is, the database 230 stores the video file position 'video URL' of the actual video file extracted from the flash file, the time at which the video URL is extracted, and the expiration time at which the video URL is valid from the extracted time, in association with the flash file. Can be. For example, the database 230 may include a video URL 'http://flvorg.pandora.tv/8xf.flv' extracted from a flash file, a time '2008.8.18 9:00' and an expiration time ' 2008.8.19 9:00 'can be stored in correspondence with the address' http://imgcdn.pandora.tv//EGplayer.swf' of the flash file (see FIG. 3).

For example, the address extracting unit 220 may determine whether the video URL corresponding to the first flash file is searched in the database 230, and if the search result is found, extract the video URL from the database 230. Can be. That is, the address extracting unit 220 searches the database 230 for the address of the first flash file, and if a flash file matching the address of the first flash file is found, the address extracting unit 220 corresponds to the flash file. The video URL 'http://flvorg.pandora.tv/8xf.flv' can be extracted from the database 230.

In this case, the address extracting unit 220 determines the validity of the video URL searched from the database 230 in response to the first flash file, and if the validity is verified as a result of the determination, the video URL from the database 230. Can be extracted. That is, the address extraction unit 220 checks the expiration time '2008.8.19 9:00' for the extracted video URL 'http://flvorg.pandora.tv/8xf.flv' in the database 230, If the current time has not passed the expiration time, it may be determined that the validity of the extracted video URL is authenticated.

Alternatively, the address extracting means 220 executes the first flash file by executing the first flash file when the video URL is not searched in the database 230 or when the validity of the searched video URL is not authenticated. You can extract the video URL from. That is, the address extracting unit 220 may execute the first flash file on the web accelerator server to capture the location of the video file, that is, the video URL, requested by the executed first flash file to the web server.

The address extracting unit 220 may store the extracted video URL and the first flash file in the database 230 so as to correlate with the time at which the video URL is extracted. For example, the address extracting unit 220 may update the extracted video URL, the extracted time, and the expiration time when a valid video URL is previously stored corresponding to the first flash file, or the first flash may be updated. In the case of extracting the video URL by executing the file, the address extracting unit 220 matches the extracted video URL, the extracted time, and the expiration time with the address of the first flash file in the database 230. Can be added to

The data providing means 240 functions to provide the extracted video URL to the mobile internet browser.

That is, the data providing means 240 confirms the version of the script language supported by the mobile Internet browser from the version list, and writes the extracted video URL in the script language of the checked version to generate a second flash file. The generated second flash file may be provided to the mobile internet browser. For example, the data providing unit 240 writes the extracted video URL in the script language of the version checked in the version list 'Action 1.0, ActionScript 2.0' regarding the version of the script language supported by the mobile Internet browser, and the second flash file. And generate the generated second flash file to the mobile internet browser.

As another example, when it is determined that the first flash file is impossible to be implemented in the mobile internet browser, the data providing means 240 provides an upgrade program along with the first flash file to the mobile internet browser to upgrade the upgrade. You can have the program installed.

Here, the upgrade program may be a program for version-up so that the mobile Flash browser interprets and executes the first flash file written in a higher version script language. Accordingly, the mobile internet browser installed with the upgrade program may extract the video URL of the video file by executing the first flash file.

The video conversion server 250 receives the video file identified by the video URL from the web server as the play command for the video URL is generated in the mobile internet browser, and receives the received video file from the mobile internet browser. It converts to the playback environment in the and serves to provide to the mobile Internet browser in response to the playback command.

In response to the execution request for the second flash file received from the web accelerator server, the mobile internet browser interprets a script language of the second flash file to extract a video URL, and then extracts the extracted video URL from the video conversion server 250. By transmitting to, it is possible to generate a playback command for the video URL.

That is, the video conversion server 250 receives the video file to be actually played from the web server by using the video URL transmitted from the mobile internet browser according to the playback command, and the video conversion server 250 is connected to the mobile internet. The video file may be converted as received from a web server and provided to the mobile internet browser in real time so as to suit a playback environment (for example, a size or codec of a mobile terminal) in a browser.

In addition, the mobile internet browser may play the converted video file received from the video conversion server 250 in real time using a dedicated video player (RTS Player).

Therefore, according to the present invention, if the script language included in the first flash file requested from the mobile internet browser is not feasible in the mobile internet browser, the server executes the first flash file to extract the video URL and extracts the video URL from the mobile internet browser. By providing the extracted video URL to the browser, it is possible to easily play the video file using the video URL in the mobile Internet browser.

According to the present invention, when a first flash file written in a script language of an uninterpretable version is requested in a mobile internet browser, a web URL is executed by a server during web acceleration to extract a video URL and extract the video URL into a mobile internet browser. By providing the second flash file written in the script language of the interpretable version of the scripted video URL, the mobile Internet browser can play the video file regardless of the version of the script language in which the flash file is created.

Further, according to the present invention, by storing the video URL extracted from the first flash file, the extracted time and expiration time in a database corresponding to the first flash file, thereafter, the flash file requested by the mobile Internet browser in the database When searching and searching, it is possible to simply extract the video URL stored corresponding to the flash file from the database without executing the flash file.

In the mobile internet browser, the web accelerator is configured to display the first flash file of the flash area included in the website according to the input of the URL 'http://channel.pandora.tv/channel/video.ptv' of the 'Video UCC website'. You can ask the server.

In this case, the web accelerator server according to an embodiment of the present invention may download the requested first flash file from the web server, and determine whether the script language of the first flash file can be implemented in a mobile internet browser. If the written version of the scripting language is 3.0 and cannot be implemented in a mobile Internet browser, the web accelerator server executes a first flash file to extract a video URL of an actual video file requested by the first flash file, and extract the The generated video URL in a script language supported by the mobile internet browser to generate a second flash file 410, and provide the generated second flash file 410 to the mobile internet browser as shown in FIG. 4. have.

5 is a flowchart illustrating a procedure of a video file providing method according to an embodiment of the present invention.

The video file providing method may be implemented by the video file providing system of the present invention. In addition, in the following description of FIG. 5, FIG. 5 will be described with reference to FIG. 2.

In step S510, the web accelerator server downloads the first flash file requested from the mobile internet browser from the web server.

The first flash file may include an address in which a video file to be actually played is located in a script language. For example, the first flash file may be a swf (shockwave flash) file format, and the swf file may include an URL of an flv file, which is a video file to be actually reproduced, in ActionScript.

In this case, when a connection to the website including the SWF file is requested, the downloading means 210 may determine that the first flash file is requested from the mobile internet browser, and the web server may store the requested first flash file. You can download it from

That is, the video file providing system according to an embodiment of the present invention may record the URL of the video UCC website of 'Pandora TV, M & Cast, M-Gun, etc.' in a table in advance, and the download means 210 may use the mobile Internet. When the identification information of the website requested to be accessed from the browser is recorded in the table, the mobile internet browser may determine that the first flash file is requested, and download the requested first flash file from the web server.

In operation S520, the web accelerator server identifies a script language associated with the downloaded first flash file, and in operation S530, the video file providing system determines whether the identified script language can be implemented in the mobile Internet browser. If it is determined that it is impossible, a video URL is extracted from the first flash file.

For example, the version list includes a version of the ActionScript language supported by the mobile Internet browser 'ActionScript 1.0, ActionScript 2.0', and if the written version of the script language associated with the first Flash file is identified as 'ActionScript 3.0', the address extracting means 220 may determine that the implementation is impossible and extract a video URL from the first flash file.

In addition, the address extracting unit 220 may store the extracted video URL and the first flash file in the database 230 so as to correlate with the time at which the video URL is extracted.

In step S540, the web accelerator server provides the mobile internet browser with a second flash file generated by creating the extracted video URL in a version of a script language supported by the mobile internet browser.

For example, the data providing unit 240 writes the extracted video URL in the script language of the version checked in the version list 'Action 1.0, ActionScript 2.0' regarding the version of the script language supported by the mobile Internet browser, and the second flash file. And generate the generated second flash file to the mobile internet browser.

As another example, when it is determined that the first flash file is impossible to be implemented in the mobile internet browser, the data providing means 240 provides an upgrade program along with the first flash file to the mobile internet browser to upgrade the upgrade. You can have the program installed.

Here, the upgrade program may be a program for version-up so that the mobile Flash browser interprets and executes the first flash file written in a higher version script language. Accordingly, the mobile Internet browser in which the upgrade program is installed may execute the first flash file to extract the video URL of the video file.

In step S550, the video conversion server receives a video URL extracted from the mobile internet browser according to the execution request for the second flash file in the mobile internet browser, and in step S560, the video conversion server is identified by the video URL. A video file to be received from the web server.

In operation S570, the video conversion server converts the received video file according to the environment of the mobile terminal and provides the same to the mobile internet browser.

In response to the execution request for the second flash file received from the web accelerator server, the mobile internet browser interprets a script language of the second flash file to extract a video URL, and then extracts the extracted video URL from the video conversion server 250. By transmitting to, it is possible to generate a playback command for the video URL.

That is, the video conversion server 250 receives the video file to be actually played from the web server by using the video URL transmitted from the mobile internet browser according to the playback command, and the video conversion server 250 is connected to the mobile internet. The video file may be converted as received from a web server and provided to the mobile internet browser in real time so as to suit a playback environment (for example, a size or codec of a mobile terminal) in a browser.

In addition, the mobile internet browser may play the converted video file received from the video conversion server 250 in real time using a dedicated video player (RTS Player).

Therefore, according to the present invention, if the script language included in the first flash file requested from the mobile internet browser is not feasible in the mobile internet browser, the server executes the first flash file to extract the video URL and extracts the video URL from the mobile internet browser. By providing the extracted video URL to the browser, it is possible to easily play the video file using the video URL in the mobile Internet browser.

According to the present invention, when a first flash file written in a script language of an uninterpretable version is requested in a mobile internet browser, a web URL is executed by a server during web acceleration to extract a video URL and extract the video URL into a mobile internet browser. By providing the second flash file written in the script language of the interpretable version of the scripted video URL, the mobile Internet browser can play the video file regardless of the version of the script language in which the flash file is created.
