Description

Multimedia data distribution path tracking system and its method {SYSTEM AND METHOD FOR TRACING DISTRIBUTION ROUTE OF MULTIMEDIA DATA}

The present invention relates to a system for tracking a distribution path of multimedia data in a network, and more particularly, to a distributor identifier or a distribution path in multimedia data source access information when multimedia data stored in a platform system is distributed. The present invention relates to a system and a method for tracking a distribution path of multimedia data in a network by inserting the same and recording a distribution path when the multimedia data is exposed.

Hereinafter, the conventional technology will be described based on a moving picture data service system as one example of a multimedia data service.

In the conventional moving picture data service system, moving picture data is stored in a specific file server to distribute the access information of the moving picture data, thereby providing moving picture reproduction in a news site, a portal site or a blog, a personal homepage, and the like.

Recently, video data taken by general users under the name of User Created Content (UCC) or video data edited from existing video data has been used by many people for purposes such as delivering news information and distributing advertisements as well as personal promotions. We are evolving into contents that we can.

1 is a diagram schematically illustrating a service system of moving image data in the related art.

The video data service system shown in FIG. 1 includes a video recording apparatus 10 and 20 of a video provider, a video data editing apparatus 11, a video platform server 30, a video distribution server 40, and a video receiving client 50 and 51. , 52).

The video provider may directly transmit the captured video to the video platform server 30 by using the owning apparatuses 10 and 20. Alternatively, the captured video data is edited using the editing apparatus 11 and transmitted to the video platform server 30.

The video platform server 30 stores the transmitted video data and provides the video distribution server 40 with access information for accessing the video data. The video platform server 30 and the video distribution server 40 may be operated on separate systems or integrated systems.

The video distribution server 40 may be a portal or a news site, and recently, may be operated by a service site that distributes videos professionally. The video distribution server 40 provides access information of the video content along with text and image content, so that the clients 50, 51, and 52 view the video stored in the video platform server 30 through the video content access information. Do it.

The user can watch the video using a professional video viewing program installed in the client (50, 51, 52). In addition, recently, a technology for encoding and providing a video into a flash file having a “flv” extension so that a video can be viewed even without a specific video viewing program has been developed.

Unlike general video files, the Flash files provide various editing functions such as special effects and overlay functions, and can easily insert links or advertisements that move to other sites. Make it possible. For example, based on the number of times that video data inserting a specific advertisement is distributed and played or the number of clicks on an advertisement, commercial use such as sharing the income between the original creator and the middle distributor of the video and the advertisement is possible.

However, the conventional video data service system only suggests a technology for providing video distribution online, and does not provide a function for determining a distribution level of a distributor by tracking a distribution path of a distributed video.

However, as described above, in the video data service system, the commercial use through distribution and sharing of video data is important, so the role of the distributor is important. Therefore, in order to implement a business model that selects the best distributors for active distribution of video data and implements a certain benefit, a system and a method for tracking the distribution path are essential.

This problem of the prior art is applied not only to moving pictures but also to various multimedia data services such as images, charts and sound sources.

2 is a block diagram showing the overall configuration of the video distribution path tracking system by the distributor registration according to an embodiment of the present invention.

In an embodiment of the present invention, an address of a web program that does not include a distributor identifier that is an element identifying a distributor is called a first web program address, and an address of a web program including the distributor identifier is called a second web program address. It is called.

If there is a video to be distributed, the video distributor client 100 accesses the video platform system 200 and requests distributor registration. The video distributor client 100 receives video data source access information including the distributor identifier registered in the video platform system 200 from the video platform system 200 through the registration request, and distributes the video. Post to distribution server 300. The video distributor client 100 may be a personal computer, a notebook, a mobile communication terminal, a PDA, a web pad, or the like.

The video platform system 200 uploads captured video data or data edited from existing video data through a network, and encodes and stores the uploaded video in a specific format (for example, a “flv” file format). The stored video data may be reproduced by the user of the video receiving client 400 through a player in the form of a flash file (eg, a “swf” file) via the video distribution server 300.

If there is a distributor registration request from the video distributor client 100, the video platform system 200 generates a unique distributor identifier for the distributor who has requested distributor registration. When the video platform system 200 requests a video data source access information from the video distributor client 100, the video platform system 200 generates a second web program address corresponding to the distributor identifier, and includes the same in the video data source access information. Allow video distributor client 100 to copy.

Thereafter, the video data source access information including the second web program address is loaded in an arbitrary web page, and when the video is called through the web page, the video platform system 200 is included in the received second web program address. Retrieves the distributor identifier and logs the retrieved distributor. Also, through the environment variable sent by the web program, the URL information of the web page where the current video is exposed is searched and the URL information is recorded in the log. Through this, it is possible to grasp the URL information of the primary distributor of the distributed video and the currently exposed web page. The video platform system 200 transmits a video related file capable of playing a video to a client that opens the web page in the form of a flash plug-in mounted on the web page.

The video related file may include a player file, and the player file may be a flash file using a swf extension.

The video distribution server 300 provides a portal site, a news page, a blog, an email, and the like, and supports the video receiving client 400 to play the video through a web browser.

The video receiving client 400 connects to the video distribution server 300 and requests playback of a desired video. The video receiving client 400 may be a personal computer, a notebook, a mobile communication terminal, a PDA, a web pad, or the like.

Through the above-described configuration, the video platform system 200 may track the distribution path of the video by including the distributor identifier in the video data source access information and recording the distributor data in the log through the distributor identifier when there is a video call. .

3 is a block diagram showing a detailed configuration of a video platform system 200 according to an embodiment of the present invention.

The video platform system 200 includes a web server module 310, a distributor data processor 320, a web program driver 330, a media file server 340, an encoding server 350, and a DB server. Components of the video platform system 100 may be implemented as separate hardware, but may also be implemented as a program installed on one hardware.

The web server module 310 provides a web page for users to conduct web-based communication to the video platform system 200. Through a web page provided by the web server module 310, users may register a video or take call information regarding the registered video, that is, video data source access information (eg, an <object> tag). In addition, the web server module 310 communicates with the video distribution server 300 or the video distributor client 100 through an Internet communication protocol (eg, http protocol).

The distributor data processing unit 320 generates a distributor identifier, generates a second web program address, searches for a distributor identifier, and records a distributor log.

The distributor identifier is a unique identifier of the registered distributor. The distributor identifier may be generated using, for example, a member ID registered in a web page provided by the video platform system 100. The second web program address is generated by attaching the distributor identifier to the web program address included in the moving image data source access information as described above. As such, the distributor data processor 320 generates a unique distributor identifier for each registered distributor, and generates a second web program address by using the distributor data. The distributor data processor 320 transmits the distributor identifier and the second web program address to the DB server 360 and stores them.

If there is a video call request, the distributor data processor 320 searches for a distributor identifier in the web program address received with the call request, and records the retrieved identifier in a log. In addition, through the environment variables transmitted by the web program, the URL information of the web page to which the current video is exposed is searched and the URL information is recorded in the log. The distributor data processing unit 320 transmits data about the recorded log to the DB server 360 and stores the data.

The web program driver 330 drives a web program corresponding to the first web program address or the second web program address transmitted to the video platform system 200. The web program largely performs a video related file call function for playing a video and a web browser environment variable acquisition function for tracking a video exposure. Therefore, the web program driver 330 requests the media file server 340 for the called video file and stores the obtained browser environment variable information in the DB server 360.

The media file server 340 stores encoded video data to be provided through the video distribution server 300. Links or <object> tag information, i.e., video data source access information, including a web program that can access the stored encoded video data are posted to the web server module 310 of the video platform system 200, and the video platform system. Users who visit the web page of 200 can copy and so-called "embedding".

The encoding server 350 encodes a video registered by the video registrant in a specific manner (for example, a flash method). In addition, it performs a function of inserting advertisements, watermarking, link information, image information, and the like into a video, and inserts a program for acquiring environment variables into a video-related file. The encoding server 350 may encode an arbitrary video file in a “flv” file format using, for example, a codec developed by ON2 Technologies of the United States.

The DB server 360 may include a plurality of databases. For example, information about encoded media files, information about video registrants or advertisers, information about video related files for web programs, environment variable information for web browsers, exposure information for video players, distributor identifier information, and distributors. Log record information may be stored in a database.

4 is a block diagram showing a detailed configuration of the distributor data processing unit 320 according to an embodiment of the present invention.

The distributor data processor 320 includes a distributor identifier generator 321, a second web program address generator 322, a distributor identifier searcher 323, and a distributor log recorder 324. Components of the distributor data processing unit 320 may be implemented as separate hardware, but may be implemented as a program installed on one hardware.

The distributor identifier generator 321 and the second web program address generator 322 are driven when the distributor data is registered and the video data source access information for registered distributors is generated. The distributor identifier search unit 323 and the distributor log recorder are generated. 324 is driven when a video distributed by the video distribution server 300 is exposed and there is a video call from the video distribution server 300.

The distributor identifier generation unit 321 generates a unique distributor identifier for each distributor registration request. As described above, the distributor identifier may be generated by using a member ID registered in a web page provided by the video platform system 100 or by using a method for identifying each other distributor. Can be. Through this distributor identifier, the video platform system 200 may collect and store data on the distribution path by tracking the distribution path, that is, the first distributor, and recording the same in a log.

When there is a request for access to moving picture data source information by the registered distributor, the second web program address generator 322 uses the distributor identifier generated by the distributor identifier generator 321 to obtain the second web program address. Create The second web program address includes the address and distributor identifier of the first web program as described above. In this case, the distributor identifier included in the second web program address does not affect the running of the web program, and is used only for tracking the distribution path.

The distributor identifier search unit 323 retrieves the distributor identifier from the address of the web program received by the video call. The distributor identifier search unit 323 determines whether the address of the web program received when the video call is the first web program address or the second web program address, and if the address of the received web program is the second web program address, Retrieve the distributor identifier from the second web program address.

The distributor log recorder 324 records data about a distributor corresponding to the distributor identifier in the log when the distributor identifier is searched by the distributor identifier search unit 323. The data on the distributor is preferably data related to moving picture distribution.

5 is a flowchart illustrating a method of tracking a distribution path of a video according to an embodiment of the present invention.

In step S100, if there is a distributor registration request, a distributor identifier is generated. Each Distributor who has requested Distributor Registration has its own Distributor Identifier, which may be generated using a Member ID as described above or using numbers and letters, and may also identify each Distributor. Can be generated using other methods.

In step S105, when there is a request for generating moving picture data source access information from a registered distributor, a second web program address is generated. The second web program address is generated using the distributor identifier generated in step S100. As described above, the second web program address is an address of a web program, that is, an address including a first web program address and a distributor identifier.

For example, the video data source access information including only the address of the web program, that is, the first web program address is as follows.

<object ....> ....

<embed src = ”http://play.tagstory.com/player/TS00@V000032024”> </ embed>

.... </ object>

At this time, the second web program address including the first web program address and the distributor identifier is as follows. In this case, the distributor identifier is generated using the member ID as an example.

<object ....> ....

<embed src = ”http://play.tagstory.com/player/TS00@V000032024@UserID”…. … > </ embed> .... </ object>

In this case, the second web program address is generated by attaching the distributor identifier “@UserID” to the first web program address.

Of course, it is also possible to generate the second web program address by combining the distributor identifier and the first web program address in a manner different from the above example.

In step S110, a video call is received from the video distribution server. This video call is made in the case of video exposure, and receives a first web program address or a second web program address simultaneously with the video call.

In step S115, it is determined whether the web program address received in step S110 is the second web program address. This determination is made based on the presence or absence of the distributor identifier by searching for the distributor identifier in the received web program address. That is, when the distributor identifier is searched for in the web program address received in step S110, it is determined as the second web program address, and when the distributor identifier is not searched, it is determined as the first web program address. That is, the video data source access information including the second web program address may be determined to be distributed from the registered distributor.

In step S120, when it is determined that the web program address received in step S115 is the second web program address, data about the distributor is recorded in a log based on the distributor identifier retrieved in step S115. In this case, the data on the distributor is preferably data related to video distribution, as described above.

Further, in step S120, the URL information of the web page to which the current video is exposed is searched through the environment variable transmitted by the web program, and the retrieved URL information is recorded in the log. Through this, it is possible to determine through which URL the distributed video is exposed.

In step S125, when the web program address received in step S115 is determined to be the first web program address or when data on the distributor is recorded in the log in step S120, a web program corresponding to the web program address is generated. Drive and thereby play the video. As described above, since the second web program address is the same as the normal first web program address after the distributor identifier is removed, after the distributor log is recorded, the second web program address is removed and then the web program corresponding to the first program address is driven. can do.

6 is a block diagram showing the overall configuration of a video distribution path tracking system according to another embodiment of the present invention.

In another embodiment of the present invention, the URL information obtained by the video data source access information received from the video distribution server 700 is called first URL information, and is received from the video distribution server 700 by a web program. URL information extracted from one web browser environment variable is called second URL information.

That is, the URL information included in the portion of the video data source access information is the first URL information, and the URL information of the web page where the current video exposure has occurred is the second URL information. In other words, the first URL information is URL information of the web page added to the video data source access information when copying (so-called, embedding) the video data source access information from the video player exposed to the web page. For example, if the user clicks on the "embed" button provided in the video player to copy the video data source access information from the video player exposed on the web page, the URL information of the web page where the video player is exposed is displayed. It is copied in addition to the source access information. Therefore, when the video data source access information is distributed through various web pages through this process, URL information of web pages before the web page to which the current video player is exposed is included in the first URL information.

Meanwhile, the second URL information is URL information obtained by reading environment variable information of a web page on which a current video is exposed. If embedding is performed in the web page where the video is exposed, the second URL information may be included in the video data source access information as the first URL information.

The video receiving client 500 accesses the video distribution server 700 and requests to play a desired video. The video receiving client 500 may be a personal computer, a notebook, a mobile communication terminal, a PDA, a web pad, or the like.

As in FIG. 2, the video platform system 600 uploads captured video data or data edited from existing video data through a network, and uploads the uploaded video in a specific format (eg, “flv” file format). Encode and save. The stored video data may be reproduced by a user of the video receiving client 500 through a player in the form of a flash file (eg, a “swf” file) via the video distribution server 700.

When the video platform system 600 receives a video call from the video distribution server 700, the video platform system 600 retrieves encrypted first URL information from the video data source access information received from the video distribution server 700, and encrypts the encrypted first URL information. If there is 1 URL information, the first URL information is obtained by decoding it. Then, URL information is extracted from a web browser environment variable received from the video distribution server 700 by a web program to obtain second URL information. The video platform system 600 records the first URL information and the second URL information in a log to track the video distribution path.

The web program included in the video data source access information receives a video play request and requests a video call to the video platform system 600. In addition, the web program transmits the web browser environment variable of the video receiving client to the video platform system 600 to cause the video platform system 600 to obtain a second URL address. In addition, a video related file is received from the video platform system 500 to provide a video to a video receiving client.

The video distribution server 700 provides a portal site, a news page, a blog, an email, and the like, and supports a video receiving client to play the video through a web browser.

Through the above-described configuration, the video platform system 600 may track the distribution path of the video by obtaining the first URL information and the second URL information and recording them in a log. In other words, it is possible to determine which web page has been previously embedded through the first URL information, and which web page is currently exposed or played on which web page through the second URL information.

7 is a block diagram showing a detailed configuration of a video platform system 600 according to another embodiment of the present invention. The video platform system 600 includes a web server module 610, a URL information data processor 620, a web program driver 630, a media file server 640, an encoding server 650, and a DB server 660. . Components of the video platform system 600 may be implemented by separate hardware, but may be implemented by a program installed on one hardware.

The web server module 610 provides a web page for users to make web-based communication to the video platform system 600. Through a web page provided by the web server module 600, users may register a video or take call information regarding the registered video, that is, video data source access information (eg, an <object> tag). In addition, the web server module 610 communicates with a video distribution server or a video distributor client through an Internet communication protocol (eg, http protocol).

The URL information data processor 620 retrieves URL information corresponding to the video distribution path and records the retrieved URL information in a log. When the user requests to play the video through the web page provided by the web server module 610, the URL information data processing unit 620 receives the video data source access information and the web browser environment variable together with the request, and receives the video. The first URL information and the second URL information are obtained by searching the data source access information and the web browser environment variable. When the URL information included in the video data source access information is encrypted, the URL information data processing unit 620 may decrypt the information to obtain the first URL information. The URL information data processor 620 records the obtained first URL information and the second URL information in a log, and stores the log record in the DB server 660 to database the video distribution path.

The web program driver 630 drives a web program corresponding to the address of the web program transmitted to the video platform system 600. The web program largely performs a function of calling a video related file for playing a video and obtaining a web browser environment variable for tracking a video exposure. Therefore, the web program driver 630 requests the media file server 640 for the called video file and stores the obtained web browser environment variable information in the DB server 660.

The media file server 640 stores encoded video data to be provided through the video distribution server 700. The link or <object> tag information including a web program that can access the stored encoded video data is posted to the web server module 610 of the video platform system 600 to display a web page of the video platform system 600. It allows visitors to copy and so-called "embedding".

The encoding server 650 encodes the video registered by the video registrant in a specific manner (for example, a flash method). In addition, it performs a function of inserting advertisements, watermarking, link information, image information, and the like into a video, and inserts a program for acquiring environment variables into a video-related file. The encoding server 350 may encode an arbitrary video file in a “flv” file format using, for example, a codec developed by ON2 Technologies of the United States.

The DB server 660 may include a plurality of databases. For example, information about an encoded media file, information about a video registrant or advertiser, information about a video-related file corresponding to a web program, environment variable information on a web browser, exposure information on a video player, URL information on a distribution server. And log record information of URL information of the distribution server may be stored in a database.

8 is a block diagram showing a detailed configuration of the URL information data processing unit 620 according to another embodiment of the present invention.

The URL information data processing unit 620 includes a URL information obtaining unit 621 and a URL information log recording unit 622. Components of the above URL information data processing unit 620 may be implemented by separate hardware, but may also be implemented by a program installed on one hardware.

The URL information obtaining unit 621 obtains the first URL information and the second URL information. The URL information acquisition unit 621 retrieves URL information in the video data source access information received from the video distribution server 700 to obtain first URL information. When URL information in the video data source access information is encrypted, the URL information acquisition unit 621 may decrypt the information and obtain the first URL information. As described above, the URL information acquisition unit 621 receives the web browser environment variable of the video distribution server 700 to obtain second URL information therefrom.

The URL information log recording unit 622 records the first URL information and the second URL information acquired by the URL information acquisition unit 621 in the log. The first URL information and the second URL information recorded in the log may be transmitted and stored in the DB server 660 to be a database for tracking the distribution path. For example, the second URL information is information about a web page to which the current video is exposed, and the first URL information is information about a previous web page on which the current video data source access information has been embedded.

The video related file includes a video player file f10, a video skin file f20, a video content file f30, a distribution server tracking program f40, and other additional service files f50.

The video player file f10 includes player data f11 and web browser environment variable request data f12. Here, the video player data f11 is data for operating the reproduction of the video data source access information. The video player data f11 has an interface for a client user to perform video playback, playback interruption, etc., and transmits event information generated in the operation of the interface to the video platform system to stop playback and playback of video. Can be done.

The web browser environment variable request data f12 is data for requesting an environment variable of a web browser in which a video exposure occurs when a player is executed. The web browser environment variable request data f12 serves to obtain web browser environment variable information when the web program in the <object> tag fails to obtain environment variable information. In the flash file, the environment variable information of the web browser can be obtained through the ExternalInterface call method of JavaScript. The Flash ActionScript syntax can be used with ExternalInterface.call (“eval”, “window.location.href”).

The movie skin file f20 includes data related to one of the various skins that adorn the movie player. The video skin is applied to the player to provide various visual effects.

The video content file f30 is a video data source access information file to be played, and may be downloaded as a flv file by encoding a video registered by another user. The flv file may be downloaded to the client according to a play and stop play event of the video player.

The distribution server tracker f40 encrypts the current distribution path, i.e., the URL information of the web page of the current video distribution server, if a copy of the video data source access information is made (e.g. embedded) on the exposed player, The encrypted URL information is included in the moving image data source access information. For information about the current URL, use the syntax of Request.ServerVariables [“HTTP_REFERER”] in a portion of the web program to obtain the URL information in the browser environment variables if the web program uses the .NET language. Can be. In addition, when the encrypted URL information is included in the video data source access information, only a predetermined number of URL information may be controlled to be included in the video data source access information. For example, if you want to track up to the fifth distribution path, the distribution server tracker (f40) encrypts the URL information of the current video distribution server only if the URL information included in the video data source access information is less than five. Include in access information. This is to prevent the unnecessary increase in the size of the video data source access information due to the inclusion of excessive URL information.

The other additional service file f50 includes information about various services added to video playback. The other additional service file f40 may include a summary image of a video, an annotation, an advertisement, a copyright holder identifier, link information, and the like.

The web browser environment variable request data f12 described above is included in the video player file f10 and may be driven together when the video player is exposed. The web browser environment variable request data f12 may be used to preliminarily obtain environment variable information when the web program included in the <object> tag fails to obtain environment variable information.

In another embodiment of the present invention, the web browser environment variable request data f12 is illustrated as operating as part of the video player file f10, but the protection of the present invention is performed even if the same operation is included in any of the above-described video-related files. It does not go out of scope.

10 is a flowchart illustrating a method of tracking a distribution path of a video according to another embodiment of the present invention.

In step S200, the video data source access information is posted in the video distribution server. The video data source access information may be registered by being copied from a web page provided by the video platform system or a web page of another video distribution server. The registration may be performed by creating a post using a <object> tag or the like on a web page.

In step S205, the above video is exposed in the video distribution server. As described above, the "video exposure" is a concept that includes both the exposure of a player including a still image before playback and the exposure of content by playback.

In step S210, the web program mounted in the video data source access information registered in the video distribution server receives a copy request for the video data source access information. For example, the video player provides a video embed button, and clicking the embed button copies the video data source access information.

In step S215, the web program searches for the number of encrypted first URL information included in the moving image data source access information and determines whether the number is less than a threshold. This threshold may be determined by a video producer, a video provider, or other video distribution person in accordance with the purpose of tracking distribution paths. In addition, the threshold value can be changed through the web program change by the video platform system even after the video distribution is performed several times. The determination of the threshold of the number of encrypted first URL information is to prevent the size of the moving image data source access information from being unnecessarily increased due to the excessive URL information as described above.

In step S220, when the number of URL information encrypted in step S215 is less than the threshold value, the web program loaded in the video data source access information in the video distribution server obtains the URL information from the environment variable information of the video distribution server. do. This URL information is for creating or adding first URL information.

In step S225, the URL information obtained in step S220 is encrypted to obtain encrypted URL information of the video distribution server. The encryption of the URL information is done by a web program loaded with moving image data source access information. By encrypting the URL information, the URL address included in the video data source access information or the like may be modified or added to prevent manipulation of the distribution path in an illegal manner.

In step S230, the URL information encrypted in step S225 is inserted into the moving image data source access information to update the moving image data source access information. The following is an example of a tag for encrypted URL information included in the video data source access information.

<PARAM NAME = FlashVars Value = ”dist1 = http: //www.distsite1.com”>

<EMBED FlashVars = ”dist1 = http: //www.distsite1.com”> </ EMBED>

The above tag is added to the tag of the existing video data source access information, so that the video data source access information is updated with the addition of the URL information. Where dist1 represents the URL of the primary video distribution server and www.distsite1.com represents the URL of the primary video distribution server. In the above example, the URL is represented as www.distsite1.com, which is not encrypted. However, this is for convenience of the example. As described above, the URL information of the video distribution server is encrypted and included in the tag of access information of the video data source. .

In step S235, the moving image data source access information updated in step S240 corresponding to the request in step S210 is copied. Therefore, the video data source access information copied according to the request for copying the video data source access information becomes the video data source access information including the URL information of the video distribution server that receives the request for copying the video data source access information. Therefore, when the video data source access information copied in step S235 is distributed to the web site of another video distribution server, the video data source access information may include the distributed path.

In step S240, if it is determined in step S215 that the number of encrypted URL information included in the moving image data source access information is greater than or equal to the threshold value, the encrypted URL information is copied. Therefore, the video data source access information copied according to the request for copying the video data source access information becomes the video data source access information including the URL information of a predetermined number of distribution paths.

In step S300, if there is a video exposure in the video distribution server in step S205, the video platform system may determine the video data source access information included in the video distribution server and the web browser environment variables of the web site of the video distribution server. Receive. The video data source access information and web browser environment variables received by the video platform system are transmitted from the video distribution server to the video platform system by a web program loaded with the video data source access information in the video distribution server.

In step S305, the encrypted URL information in the moving image data source access information received in step S300 is retrieved and decrypted, and the first URL information is obtained using the decrypted URL information. For example, if the current video distribution server is the third distribution path, the primary video distribution path is www.dist1site.com, and the second video distribution path is www.dist2site.com, the first URL information is primary Include the video distribution paths www.dist1site.com and www.dist2site.com.

In step S310, the URL information of the video distribution server is retrieved from the web browser environment variable received in step S300 to obtain second URL information. For example, if the URL of the current video distribution server is www.dist3site.com, the second URL information includes www.dist3site.com, which is the URL of the current video distribution server.

In step S315, the first URL information obtained in step S305 and the second URL information obtained in step 310 are recorded in a log. Therefore, in this case, all information about the distribution path of the video up to the current video distribution server is recorded in the log. If the recorded log information is reviewed, it may be confirmed that a video having been embedded in the web page corresponding to the first URL information is exposed in the web page corresponding to the second URL information.

As described above, it will be understood that the moving image data source in the embodiment of the present invention can achieve the object of the present invention even if it is replaced with any source of multimedia data.

In addition, the player of the multimedia data will be easily understood to mean a program or tool for exposing, playing, or launching any multimedia data.

In addition, it will be appreciated that the "flash", which is the slow-acting software, may be replaced by any low-acting software or multimedia delivery solution such as Microsoft's "silver light".
