Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a system for providing a screen display service using two-dimensional code according to an embodiment of the present invention.

A system for providing a screen display service using two-dimensional code according to an embodiment of the present invention includes a service providing server 110, a first user terminal 120, and a second user terminal 130.

In describing each component, the service providing server 110 may transmit a web page including the 2D code to the second user terminal 130 according to a request of the second user terminal 130.

In this case, the service providing server 110 may transmit not only the web page including the 2D code but also content such as a video or an image including the 2D code to the second user terminal 130.

Here, the 2D code may include at least one of a barcode and a QR code, and the 2D code may include identification information of the service providing server 110 and identification information of the second user terminal 130.

In addition, the 2D code may be included in a web page displayed on the screen of the second user terminal 130 or displayed in a content such as a video or an image.

In addition, the service providing server 110 may identify identification information of the first user terminal 120 and the second user terminal from the first user terminal 120 that recognizes the two-dimensional code displayed on the screen of the second user terminal 130. An authentication request including the identification information of 130 may be received.

Here, the first user terminal 120 may transmit an authentication request to the service providing server 110 by using the identification information of the service providing server 110 included in the 2D code.

In addition, the service providing server 110 may perform authentication to match the first user terminal 120 and the second user terminal 130 according to the received authentication request.

At this time, the service providing server 110 uses the identification information of the first user terminal 120 and the identification information of the second user terminal 130 included in the authentication request, the first user terminal 120 and the second user terminal. Authentication may be performed to match 130, and a result message for the authentication request may be transmitted to at least one of the first user terminal 120 and the second user terminal 130.

In addition, when authentication is performed, the service providing server 110 may receive screen information of the first user terminal 120 from the first user terminal 120 and transmit the screen information to the second user terminal 130.

In addition, if authentication is not performed, the service providing server 110 may transmit an authentication error message to at least one of the first user terminal 120 and the second user terminal 130.

In addition, when the screen information of the first user terminal 120 is changed, the service providing server 110 receives the changed screen information of the first user terminal 120 from the first user terminal 120 and the second user terminal ( 130).

Therefore, the first user terminal 120 and the second user terminal 130 may display the same screen information on the screen even if the screen information of the first user terminal 120 is changed.

In addition, when the service providing server 110 receives an authentication release request from the first user terminal 120, the service providing server 110 releases the connection between the matched first user terminal 120 and the second user terminal 130. The authentication release message may be transmitted to at least one of the terminal 120 and the second user terminal 130.

In this case, the service providing server 110 may receive an authentication release request from the second user terminal 130. In this case, the service providing server 110 may process the same as when receiving the authentication release request from the first user terminal 120. have.

As a result, the service providing server 110 may be included in a web page displayed on the screen of the second user terminal 130 or may be displayed in a content such as a video or an image. Various contents displayed (played) on the screen of 120 may be displayed (played) on the screen of the second user terminal 130.

On the other hand, the first user terminal 120 recognizes the two-dimensional code displayed on the screen of the second user terminal 130, the identification information and the service providing server 110 of the second user terminal 130 from the recognized two-dimensional code Identification information can be extracted.

Here, the recognition of the 2D code may be performed by photographing the 2D code through a photographing apparatus (for example, a camera) included in the first user terminal 120, and the identification information may include an IP address. .

Also, the first user terminal 120 uses the extracted identification information of the service providing server 110 to the service providing server 110 to identify the identification information of the first user terminal 120 and the second user terminal 130. The authentication request including the identification information may be transmitted.

Thereafter, when authentication is performed in response to the authentication request in the service providing server 110, the first user terminal 120 may transmit screen information of the first user terminal 120 to the service providing server 110.

In addition, when the screen information of the first user terminal 120 is changed, the first user terminal 120 may transmit the screen information of the first user terminal 120 changed to the service providing server 110.

Thereafter, the first user terminal 120 may transmit an authentication release request to the service providing server 110, and when authentication is released in response to the authentication release request, the first user terminal 120 receives an authentication release message from the service providing server 110 and displays a screen. Can be marked on.

Meanwhile, the second user terminal 130 may receive content such as a web page including a 2D code or an image or a video including the 2D code from the service providing server 110 and display the content on the screen.

In this case, the second user terminal 130 may display a web page on a portion of a specific area of the screen.

In addition, the second user terminal 130 may receive the screen information of the first user terminal 120 from the service providing server 110, and display the screen information of the first user terminal 120 on the screen.

In this case, the second user terminal 130 may display the screen information of the first user terminal 120 on a portion of a specific area of the screen.

For reference, the first user terminal 120 and the second user terminal 130 may be connected to the service providing server 110 through a network such as a mobile phone, a smart phone, a personal digital assistant (PDA), a portable multimedia player (PMP), or the like. It can include all kinds of handheld-based wireless communication device that can be, in addition to the service providing server 110 through the network, such as IPTV including desktop PC, tablet PC, laptop PC, set-top box It may also include a communication device that can be connected with.
