Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

Hereinafter, the terms "URL" and "Uniform Resource Identifier (URI)" may be used interchangeably and may be interchanged with each other.

URL shortening refers to a service that makes common URLs short and simple. URL shortening can be widely used to link various media content, especially in social media and the like.

Most web browsers can cache content such as images or videos. For example, when a user watches certain media content on the Internet using a web browser, a file of the media content may be stored in a temporary file folder of the user's terminal.

The user can provide the content cached in his terminal to other users. Thus, the user can use the cached content as a new source of content sharing. According to the web application and web browser technology of the HTML5 standard, a web browser can operate as a web server without any special native application software.

That is, the modern web browser can provide various additional functions on the web browser without using a separate application through the form of a browser extension or a web app. These additional functions may include various functions such as e-mail checks or games.

This change allows a user to access content cached by another user's browser. In addition, friends on SNS can live near each other. In other words, friendship in SNS can mean geographic proximity in many cases, and can be used as a source of media content closer than the original SNS or media service server. The following embodiments can provide one form of distributed media content sharing on SNS.

Peer-to-Peer (P2P) technology is a technology that improves the transmission efficiency of a file through a distributed sharing method in which a file is received from nearby sources around the user instead of just one source. However, building a P2P overlay network that supports minimal latency, link / node stress, and look-up time is still an open challenge.

Moreover, with P2P, there are complaints about freeing up some of the resources of your computer for an unspecified number, and you may encounter free-riding problems that only receive downloads and do not participate in file sharing. have. In addition, as a new peer of P2P is added, a problem may arise in that a broker continuously manages a list of users participating in file sharing and configures a new overlay network. The above problems can be a big obstacle in practical applications and can be regarded as open problems where no optimal solution has yet been found. The following embodiments may disclose a method of sharing media content on an SNS using HTML5 web technology.

1 is a block diagram of a terminal according to an embodiment.

The user can watch certain media content on the Internet using a web browser of the terminal 100. In this case, the terminal 100 may cache media content (ie, a file of media content) that the user watches in the terminal. The media content may be stored as a file at a specific location in the file system of the terminal.

The user may share the media content viewed by the user through a social service or the like. To share media content, a user can create a link that points to the media content and insert the generated link into a page provided by a web server. Other users can access the media content through the link above.

In this case, the media content may be provided by 1) the server that initially provided the media content to the terminal 100, or 2) the terminal 100 that cached the media content. In other words, media content may be provided by two entities. In the following, the object that originally provided the media content can be named as the origin server. In addition, an entity (ie, the terminal 110) providing a cache after media content may be referred to as a cache server.

In order for media content to be provided from each of the plurality of servers, one link needs to contain information for receiving the media content from each of the plurality of servers. For example, other users can selectively access media content stored in the origin server or media content stored in the cache server using the link. The link may include 1) first information for specifying media content stored in a first server (eg, origin server) and 2) second information for specifying media content stored in a second server (eg, cache server). Can be.

Compared with the existing URL, the URL including the first information and the second information is named as a modified URL. Here, the first information may be converted to the first URL, and the second information may be converted to the second URL. That is, the modified URL may include information for receiving media content from each of a plurality of servers including an origin server and a cache server. An example of the format of a modulated URL is described in detail with reference to FIG. 2 below.

The terminal 100 includes a transceiver 110, a storage 120, a link generation detector 130, a modulated URL generator 140, a link provider 150, a media content request detector 160, The URL generating unit 170 and the URL selecting unit 180 may be included.

The components 110 to 180 may be part of a web browser, or may be an extension of the web browser.

The transceiver 110, the storage 120, the link generation detector 130, the modulated URL generator 140, and the link provider 150 may be regarded as components for generating a modulated URL. .

In the following, the first link may be a link to first media content that a user wants to share with another user.

The transceiver 110 may receive the first media content from the server.

The storage unit 120 may store the received first media content.

The link generation detector 130 may detect a request for generating a first link for the first media content.

The modulated URL generator 140 may generate a first modulated URL for the first media content for which the generation of the first link is requested.

The first modulated URL may include information for receiving first media content from the server and the terminal 100, respectively.

The link provider 150 may provide a first link including the first modulated URL.

The transceiver 110, the storage 120, the media content request detector 160, the URL generator 170, and the URL selector 180 are regarded as components that provide media content corresponding to the modulated URL. Can be.

In the following, the second link may be a link to second media content that the user wants to access.

The media content request detector 160 may detect a request for the second media content through the second link.

The URL generator 170 may determine whether the second link includes the second modulated URL.

The second modulated URL may include information for receiving second media content from a second server and a third server, respectively.

When the second link includes the second modulated URL, the URL generator 170 may generate a first URL and a second URL for the second media content based on the second modulated URL.

The URL selector 180 may select a URL to be used for requesting the second media content among the first URL and the second URL.

The transceiver 110 may request and receive the second media content using the selected URL.

The storage unit 120 may store the received second media content.

2 illustrates a modulated URL according to an example.

The URL is a convention for telling where resources are on the network. If the generic URL is indicative of a location on a single network of particular resources, then the modulated URL 200 may represent locations on multiple networks of a particular resource (eg, media content).

The modulated URL 200 includes a protocol identification unit 210, a first delimiter 220, a first address unit 230, a second address unit 240, a second delimiter 250, and a third address unit 260. ) May be included.

The protocol identifier 210 may indicate a protocol (eg, Hyper Text Transfer Protocol (HTTP)) to which the modulated URL 200 is applied.

The first delimiter 220 may distinguish between the protocol identifier 210 and the rest of the modulated URL 200. The second delimiter 250 may distinguish between the second address unit 250 and the third address unit 260.

As described above, the modulated URL 200 may include information for receiving media content from each of the plurality of servers. The first information for receiving the media content from the first server may include a first address unit 230 and a second address unit 240. Alternatively, the first information may include a first address unit 230 and a second address unit 240. The second information for receiving the media content from the second server may include a third address unit 260, and may include a first address unit 230 and a third address unit 260. Alternatively, the second information may be composed of the third address unit 260 and may be composed of the first address unit 230 and the third address unit 260.

The first URL 270 indicating the media content in the first server may be converted into the first information, for example, by the modulated URL generator 140 or a URL shortening server to be described later. In addition, the first information may be converted into the first URL 270 by, for example, the URL generator 170 or a URL restoration server to be described later.

In addition, the first URL 280 indicating the media content in the second server may be converted into the second information, for example, by the modulated URL generating unit 140 or the URL shortening server to be described later. In addition, the second information may be converted into the second URL 280 by, for example, the URL generator 170 or a URL restoration server to be described later. Here, the second URL may include an IP address of the second server and may include a path of media content in the second server.

Here, the first information and the first URL (or the second information and the second URL) may be converted to each other by hashing. Therefore, the modulated URL may be generated based on the first information and the second information. That is, the first information may be a hashed first URL generated by applying hashing to the first URL 270. Also, the second information may be a hashed second URL generated by applying hashing to the second URL 280.

The modulated URL 200 may include information for receiving media content from each of the three or more servers. In order to include information for receiving media content from each of the three or more servers, the modulated URL 200 may include additional addressing portions. The k th additional address unit among the additional address units may include information for receiving the media content from the k + 2th server. Here, k is an integer of 1 or more and n- 2 or less. n is the number of servers.

3 is a flowchart of a link providing method of media content according to an exemplary embodiment.

The user may receive the media content by manipulating the terminal 100 to watch specific media content.

In operation 310, the transceiver 110 may receive media content.

In operation 320, the storage 120 may store the received media content.

The user may attempt to create a link to the received media content. The user may operate the terminal 100 to request the generation of a link to the media content.

In operation 330, the link generation detecting unit 110 may detect a request to create a link for media content.

In operation 340, the link generation detecting unit 110 may determine whether the media content is stored in the terminal 100. When media content is stored in the terminal 100, in order for the terminal 100 to provide the media content, a modulated URL needs to be generated. If media content is not stored in the terminal 100, the terminal 100 may not provide the media content. Thus, a generic URL for media content needs to be generated instead of a modulated URL.

If media content is stored in the terminal 100, step 370 may be performed. Otherwise, step 350 may be performed.

In operation 350, the modulated URL generator 140 may generate a URL for media content. The URL may be a URL for receiving media content from a server. In addition, the URL may be a shortened URL. An example of a method for generating a shortened URL is described in detail with reference to FIG. 4 below.

In operation 360, the link providing unit 150 may provide a link including the generated URL.

In operation 370, the modulated URL generator 140 may generate a modulated URL for media content. The modulated URL may include information for receiving media content from the server and the terminal 100, respectively.

The modulated URL may include first information and second information. The modulated URL generator 140 may generate first information by applying hashing to the first URL, and may generate second information by applying hashing to the second URL.

The first URL may point to media content in the server that provided the media content. That is, in step 310, the transceiver 110 may receive the media content using the first URL.

The second URL may point to the media content in the terminal 100. Therefore, another user may receive media content from the terminal 100 using the second URL. The terminal 100 (or a web browser of the terminal 100) may serve as a web server for providing media content.

An example of a specific method for generating the first information and the second information based on the first URL and the second URL, respectively, is described in detail with reference to FIG. 4 below.

In operation 380, the link provider 150 may provide a link including the generated modulated URL.

Here, the link may be a modified URL. If the link is a string, all or part of the string may be a modified URL.

4 is a flowchart of a method of providing a hashed URL according to an example.

In operation 410, the terminal 100 may transmit a URL to the URL shortening server 400.

The URL shortening server 400 may be a server that provides a shortening service for a URL.

In operation 420, the URL shortening server 400 may generate a hashed URL by applying hashing to the transmitted URL. By the above hashing, the length of the transmitted URL can be shortened. Thus, the hashed URL can also be called a shorten URL. In addition, the shortened URL may not include special characters such as "/" and may be composed of numbers. Also, the length of the shortened URL may be equal to or less than the length of the URL.

The URL shortening server 400 may use a hash table for hashing, and may use all or part of the transmitted URL as a hash code for the hash table. Here, a part of the transmitted URL may be a part of specifying a path in a specific server among the transmitted URLs. In addition, a part of the transmitted URL may be a part of specifying a specific server and a path within the specific server among the transmitted URLs.

In operation 430, the terminal 100 may receive the hashed URL from the URL shortening server 400.

Here, step 370 described above may include steps 410 to 430. In step 370, steps 410 through 430 may be performed twice. The first iteration is for the first URL of step 370 and the second iteration is for the second URL of step 370.

That is, the URL of step 410 may represent the first URL or the second URL of step 370. In addition, the hashed URL of step 430 may represent the first information or the second information of step 370. Accordingly, the URL shortening server 400 may generate first information by applying hashing to the first URL, and generate second information by applying hashing to the second URL. The link returned in step 360 or step 380 may include a shortened URL or a modulated URL.

The functions of the URL shortening server 400 described above in steps 410 to 430 may also be performed by the modulated URL generating unit 140.

5 is a flowchart of a method of providing, by a terminal, media content using a modulated URL according to an embodiment.

The user can request specific media content, for example by clicking on a link displayed in the browser.

In operation 510, the media content request detector 160 may detect a request for media content through a link.

In operation 520, the URL generator 170 may determine whether the link includes a modified URL. If the link does not include a modulated URL, step 530 may be performed. If the link includes a modulated URL, step 540 may be performed.

In step 530, the link may comprise a generic URL or a hashed URL (ie, a shortened URL).

In operation 530, the transceiver 110 may request and receive media content using a URL included in the link. The URL may include information for receiving media content from the server.

When the URL included in the link is a hashed URL, the hashed URL needs to be restored to the original URL before the transceiver 110 requests and receives the media content using the URL included in the link. An example of a method for recovering a hashed URL is described in detail with reference to FIG. 6 below.

In operation 540, the URL generator 170 may generate a first URL and a second URL for the media content based on the modulated URL included in the link.

The first URL may point to media content within the first server. Here, the first server may be a server that provides media content to another user's terminal. The second URL may point to media content within the second server. Here, the second server may be a terminal of another user who receives the media content from the first server, caches the received media content, and generates a link to the media content. That is, the link may be generated by the second server. In addition, the link generated by another user's terminal may be the link of step 510.

The URL generator 170 may extract the hashed first URL and the hashed second URL from the modulated URL. The URL generator 170 may generate the first URL by applying hashing to the first information of the modulated URL, and generate the second URL by applying hashing to the second information of the modulated URL.

Also, the first URL and the second URL may be generated by the URL restoration server. An example of a method of generating the first URL and the second URL using the restoration server is described in detail with reference to FIG. 6 below.

Also, the first URL and the second URL in step 540 may be hashed URLs (or abbreviated URLs). In this case, the redirecting server may be used at step 560 and the like, which will be described later.

In operation 550, the URL selector 180 may select a URL to be used to request media content from among the first URL and the second URL.

In order to select a URL to use to request media content, the following methods may be used.

In a first method, the URL selector 180 may select a server that responds faster to a ping request among servers indicated by each of the first URL and the second URL. This is because a server that responds faster to a ping request may be considered to be able to send media content to the terminal 100 in a shorter time.

In other words, step 550, 1) the URL selector 180 transmits a ping request to the first server indicated by the first URL and the second server indicated by the second URL, and 2) URL selection. The unit 180 receiving a response to the ping request from the first server and the second server, respectively, and 3) a server to which the URL selecting unit 180 responds to the ping request faster than the first server and the second server. Selecting a URL corresponding to the may include.

If one of the first server and the second server is not available, the unavailable server does not respond to the ping request. Accordingly, the URL selector 180 may select a URL indicating a server responding to the ping request.

In a second method, the URL selector 180 may select one of the first URL and the second URL based on the first geographical position indicated by the first URL and the second geographical position indicated by the second URL.

In other words, step 550 may include: 1) determining, by the URL selector 180, a geographic location estimated to be closer to the terminal among the first geographic location indicated by the first URL and the second geographic location indicated by the second URL. And 2) selecting a URL corresponding to the determined geographical location among the first URL and the second URL.

For example, when the terminal 100 is in a specific country, the URL selector 180 may display an Internet Protocol (IP) address corresponding to a country where the terminal 100 is located among the first URL and the second URL. Can be selected. Alternatively, the URL selector 180 may select a URL corresponding to the same subnetwork as the subnetwork including the terminal among the first URL and the first URL.

Alternatively, the URL selector 180 may select an IP more similar to the IP of the terminal among the first IP corresponding to the first URL and the second IP corresponding to the second URL, and select a URL corresponding to the selected more similar IP. You can choose. Here, the URL selector 180 may determine a similar degree between the two IPs based on the length of the prefix common between the two IPs.

In operation 560, the transceiver 110 may request and receive media content using the selected URL. When the selected URL is a hashed URL (or abbreviated URL), the transceiver 110 may request media content from a redirect server, which will be described later with reference to FIG. 7, using the selected URL. The returned URL can be used to request and receive media content.

In operation 570, the storage unit 120 may store the received media content.

6 is a flowchart illustrating restoration of a hashed URL according to an example.

In operation 610, the URL generator 170 may extract the hashed first URL and the hashed second URL by dividing the modulated URL. The modulated URL may include the first information and the second information described above with reference to FIG. 2. The first information may correspond to the hashed first URL. The second information may correspond to the hashed second URL.

In operation 620, the URL generator 170 may transmit the hashed first URL to the URL restoration server 600.

The URL restoration server 600 may provide a restoration service for the hashed first URL. Here, the restoration may mean returning the shortened URL to the original URL. The URL shortening server 400 and the URL restoration server 600 may be physically the same server.

In step 630, the URL recovery server 600 may calculate the original first URL by applying hashing to the hashed first URL. That is, the first URL may be generated by applying hashing to the hashed first URL.

The URL recovery server 600 may use a hash table for hashing, and may use all or part of the hashed first URL as a hash code for the hash table. Here, a part of the hashed first URL may be a part that specifies a path in a specific server among the hashed first URLs. In addition, the portion of the hashed first URL may be a portion of the hashed first URL that specifies a specific server and a path within the specific server.

In operation 640, the URL generator 170 may receive the first URL from the URL restoration server 600.

In operation 650, the URL generator 170 may transmit the hashed second URL to the URL restoration server 600.

In step 660, the URL recovery server 600 may calculate the original second URL by applying hashing to the hashed second URL. That is, the second URL can be generated by applying hashing to the hashed second URL.

In operation 670, the URL generator 170 may receive a second URL from the URL restoration server 600.

Step 540 described above with reference to FIG. 5 may include steps 610 through 670. The first information of step 540 may correspond to the hashed first URL of step 610. The second information of step 540 may correspond to the hashed second URL of step 610.

7 is a flowchart illustrating an operation of a redirect server according to an example.

The redirect server can receive the hashed URL from the terminal and send the original URL for the hashed URL to the terminal. Here, the terminal may be a terminal that cannot handle the modulated URL. Thus, the hashed URL may be a modulated URL that has not been processed by the terminal.

In step 710, the redirect server may receive the hashed URL from the terminal.

In step 720, the redirect server may determine whether the received hashed URL is a modulated URL. If the hashed URL is a modulated URL, step 730 may be performed. If the hashed URL is not a modulated URL, step 740 may be performed.

In step 730, the redirect server may remove the portion of the hashed URL. Here, the removed portion may be the second separator 250 and the third address unit 260 described above with reference to FIG. 2. Alternatively, the portion to be removed may be a part after the second separator 250 and the second separator 250.

The terminal transmitting the hashed URL may be a terminal that cannot process or identify the modified URL. The terminal that cannot handle the modulated URL may transmit the entire modulated URL to the redirect server to request media content.

In step 740, the redirect server may generate the original URL based on the hashed URL. The redirect server can generate the original URL by applying hashing to the hashed URL. Here, the hashed URL may be a shortened URL, and the original URL may be a URL before it is shortened.

In operation 750, the redirect server may return (or transmit) the generated URL to the terminal.

By the steps 710 or 750 described above, the link including the modulated URL may be used by the terminal that does not recognize the modulated URL.
