The second terminal device 200 may request streaming for an application installed in the first terminal device 100 and receive and display image data provided from the first terminal device 100.

The second terminal device 200 may receive an installation file of an application corresponding to the image data currently displayed from the first terminal device 100. In addition, upon receiving the installation authentication of the corresponding application through the server 300, the second terminal device 200 may perform the application installation using the received installation file.

The server 300 is a device for authenticating whether or not the terminal device of the application is installed. In detail, when the authentication request information is received from the second terminal device 200, the server 300 may perform an authentication process based on whether an application is approved. The server 300 may be a file server that stores installation files of applications. Meanwhile, in implementation, the server 300 may be implemented as a plurality of servers.

As described above, the network system 1000 according to the present embodiment may provide an environment in which the corresponding application can be experienced using the first terminal device 100 even when the application is not installed in the second terminal device 200. have. In addition, the second terminal device 200 acquires the installation file of the corresponding application from the first terminal device while displaying the image data of the application, and the user can easily install the installation file even if the server does not perform a separate search and download. Can be obtained. In addition, since the server 300 does not participate in the transmission of the installation file, the server load can be reduced.

In FIG. 1, although the first terminal device 100 and the second terminal device 200 have been described in different configurations, the first terminal device 100 is merely a difference between which application is already installed. May operate as the second terminal device 200, and the second terminal device 200 may also operate as the first terminal device 100. For example, when the corresponding application is installed in the second terminal device 200 by the above-described process, the second terminal device 200 may provide image data of the application to another terminal device in a streaming manner.

1, the first terminal device 100 is described as being connected to one second terminal device 200.

The image displayed at 200 may be different. Such an example will be described later with reference to FIGS. 4 to 6.

2 is a sequence diagram illustrating an application execution method and an application installation method of the present invention.

First, the second terminal device 200 requests the first terminal device 100 to stream the application installed in the first terminal device 100 (S201).

Upon receiving the request, the first terminal device 100 may request the server 300 to provide streaming to the second terminal device 200 (S202), and receive a response to the request ( S203).

When receiving a response from the server 300 that the streaming may be provided, the first terminal device 100 drives the application requested by the second terminal device 200, generates image data according to the driving, and generates the generated image data. It may be streamed to the second terminal device 200 (S204). In this case, the streaming may be performed in a P2P manner by using a communication method such as Wi-Fi Direct, NFC, Bluetooth, or the like. In this case, the P2P method is to transmit data without relaying the server 300. If the method does not cause traffic to the server, other communication methods other than the Wi-Fi Direct, NFC, and Bluetooth methods described above may be used. .

The first terminal device 100 may provide a server link address for the corresponding application to the second terminal device 200 (S205). This may be performed during the above-described streaming providing process or may be provided at the beginning of the streaming providing.

In addition, during the above-described streaming process, the first terminal device 100 may transmit to the second terminal device 200 an installation file related to an application that is a source of video data currently being streamed. At this time, the delivery of the installation file may be performed by a P2P method using a communication method such as Wi-Fi Direct, NFC, Bluetooth, and the like. The P2P scheme here also transmits data without relaying the server 300, and if the scheme does not cause traffic to the server, other communication schemes besides the Wi-Fi Direct, NFC, and Bluetooth schemes described above may be used. Meanwhile, in the implementation, the same communication method may be used for streaming the image data and the installation file described above, and different communication methods may be used. For example, if each of the first terminal device 100 and the second terminal device 200 supports Wi-Fi Direct and Bluetooth, the above-described streaming of the image data is transmitted by the Wi-Fi Direct method, and the installation file is transmitted by the Bluetooth method. Can be.

Therefore, after the user of the second terminal device 200 experiences the experience of the application installed in the first terminal device 100 in a streaming manner, the user accesses the server 300 and authenticates without searching and downloading the corresponding application. Just install the application. However, when the selection of the icon for the user's authentication operation is input before the installation file is completed, the second terminal device 200 receives the remaining installation file through the server 300, or receives the entire installation file from the server ( 300).

On the other hand, the above has been described that the streaming of the video data is made in one direction, the streaming of the video data as described above may be made in both directions. That is, when the user inputs an operation (for example, inputting a specific key, adjusting playback time, or an operation command corresponding to the corresponding application) on the image data displayed on the second terminal device 200, the operation is performed on the first terminal. The first terminal device 100 is transmitted to the device 100 and the first terminal device 100 may generate and stream image data corresponding to the delivered operation command.

For example, if the application installed in the first terminal device 100 is a game application, the first terminal device 100 may generate image data for the game application and stream it to the second terminal device 200. After receiving the user's operation command from the second terminal device 200, the first terminal device 100 may generate image data reflecting the operation command and stream the image data to the second terminal device 200.

In the above, only the game application has been described as an example of the application installed in the first terminal device 100. However, in the implementation, various applications such as an application related to video playback, an application related to music playback, an application for office work, and the like are provided in the aforementioned streaming method. An environment in which a user of the second terminal device 200 may experience an application installed in the first terminal device 100 may be provided.

Meanwhile, in the description of FIG. 2, only when the application is authenticated through the server 300, the application is described as being installed. However, if the current streaming application is an application that can be freely distributed. The above authentication process may be omitted. In this case, steps S202 and S203 described above may also be implemented in a omitted form.
