Meanwhile, the image display apparatus 200 transmits the first support information only when the mobile terminal 100 requests the first display information from the image display apparatus 200. However, the mobile terminal 100 moves without requesting the first support information. While the terminal 100 and the image display apparatus 200 are connected by the mirroring function, the mobile terminal 100 may receive first assistance information from the image display apparatus 200.

In addition, the mobile terminal 100 may generate the common support information by comparing the received first support information with the second support information of the mobile terminal 100 (S320).

Here, the second support information is information for determining a supportable application of the mobile terminal 100 and may be information regarding specifications of the mobile terminal 100. Similar to the first support information, the second support information may include user interface information, network information, display information, operating system information, and the like.

The common support information is information for determining an application that can be commonly applied to the mobile terminal 100 and the image display apparatus 200. The common support information includes specifications of the image display apparatus 200 and specifications of the mobile terminal 100. All can be determined in consideration. The common assistance information may be used to determine an application that can support the case where the image display apparatus 200 and the mobile terminal 100 are connected to each other by a mirroring function.

When the application download event occurs (S330: YES), the mobile terminal 100 may determine whether to download based on the common support information (S340). In detail, by requesting the external server to download the application information, the external server 300 may transmit the application information to the mobile terminal according to the request. The mobile terminal 100 may check compatibility with an application to be downloaded based on the common support information, and determine whether to download the application based on the inspection result. For example, the controller 180 may check the compatibility by comparing the common support information generated by the mobile terminal 100 with the received application information.

Here, the application download event may mean a program event generated according to a user's input for downloading an application from an external server. For example, the application download event may be an event generated by a user's input of purchasing or downloading a specific application from an application store.

The external server may mean a server storing an application or relaying an application download. For example, the external server may be a play store server in the case of an Android platform and an App store server in the case of an IOS platform.

On the other hand, the application information received by the mobile terminal 100 may include specification request information of the device executable application. When the mobile terminal 100 receives application information and performs a compatibility check, the mobile terminal 100 checks whether both the mobile terminal 100 and the image display device 200 have the specifications required by the specification request information. It can be determined to be compatible.

For example, when a touch input is requested as the specification request information, whether the mobile terminal 100 and the image display apparatus 200 have a touch screen or a touch pad may be checked with reference to common support information.

If it is determined that the download is possible (S350: YES), the mobile terminal 100 can download the application from the external server (S360).

On the other hand, if it is determined that the download is not possible (S360: NO), the mobile terminal 100 may display a notification of incompatibility (S370).

On the other hand, the process after the step of determining whether to download the application (S340 ~ S370) may not be performed when the application to download does not support the mirroring function. This is because it is not necessary to determine whether to download using common support information for an application that does not support the mirroring function.

In addition, the process after step S340 may not be performed even if the application to download is free. That is, only a paid application may determine whether to download based on common support information.

4 is a diagram illustrating a data transmission method between an image display device, a mobile terminal, and an external server according to an embodiment of the present invention. Before describing the data transmission method of FIG. 4, it is assumed that the first image display apparatus 200 and the mobile terminal 100 are connected to each other by a mirroring function.

Referring to FIG. 3, when the mobile terminal 100 requests the first display information from the image display apparatus 200 (S400), the mobile terminal 100 receives the first support information from the image display apparatus 200. It may be (S410).

Meanwhile, the mobile terminal 100 receives the first support information only when the mobile terminal 100 requests the first display information from the image display apparatus 200. However, the mobile terminal 100 and the mobile terminal 100 display the image without the request for the first support information. At the same time that the device 200 is connected by the mirroring function, the mobile terminal 100 may receive first assistance information from the image display device 200.

In addition, the mobile terminal 100 may generate common support information by comparing the received first support information with the second support information of the mobile terminal 100 (S420).

When an application download event occurs (S430), the mobile terminal 100 may request the external server 300 for application information to be downloaded (S440). The mobile terminal 100 may receive application information from the external server 300 (S450).

In this case, the external server 300 refers to a server storing an application or relaying an application download. For example, the external server 300 may be a play store server for the Android platform and an App store server for the IOS platform.

In addition, the mobile terminal 100 may check compatibility with an application to be downloaded based on common support information, and determine whether to download the application based on the inspection result (S460). Specifically, the compatibility may be checked by comparing the common support information generated by the mobile terminal 100 with the received application information.

Here, if it is compatible, the mobile terminal 100 may determine that it is downloadable and may request a download from the external server 300 (S470). Accordingly, the mobile terminal 100 downloads an application from the external server 300. It becomes possible to receive (S480).

On the other hand, if it is not compatible, the mobile terminal 100 may display a notification of incompatibility.

The mobile terminal according to an embodiment of the present invention described above has an effect of improving user convenience.

In detail, in consideration of whether the image display apparatus connected to the application is supported by the mirroring function, purchase of an application not executed in the image display apparatus may be prevented in advance.

In addition, a user can download an application that can be executed by the mirroring function without changing the current application distribution processor.

According to an embodiment of the present invention, the above-described method (operation flowchart) can be implemented as code that can be read by a processor in a medium in which a program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The mobile terminal 100 described above is not limited to the configuration and method of the above-described embodiments, the embodiments may be a combination of all or part of each embodiment selectively so that various modifications can be made It may be configured.
