The mobile device 300 can perform a separate operation while the streaming service is in progress, and the playback video and the streaming service of the corresponding video 200 are linked and reproduced through the Internet URL.

In order to solve the problem of internet speed, buffering is performed in a memory having a constant capacity built in the dongle 100. [

3 to 5 illustrate various function screens implemented through an application of a smartphone according to an embodiment of the smart presentation system according to the present invention.

FIG. 3 (a) is a screen showing a mouse function implemented through a smartphone, (b) shows a main home screen function, (c) shows a file list function, Function.

4A is a screen showing a music play function, FIG. 4B is a screen showing a video play function, FIG. 4C is a screen showing a document presentation function, and FIG. 4D is a screen showing an image presentation function .

FIG. 5A is a screen showing a web browser function, FIG. 5B is a screen showing a document work function, FIG. 5C is a screen showing a mobile device connection function, Screen.

That is, it is possible to easily control the fish 200 (music reproduction, movie reproduction, document editing, web surfing, etc.) through the application of the smart phone, and to present the presentation.

In addition, the mobile device 300 can be used as the PC 200 by adding a mouse and a keyboard input function.

In addition, in the mobile application, a mouse icon is clicked to control the mouse of the fish 200, and various operations such as left / right click, double click, and dragging can be performed.

In addition, when the document icon is clicked in the mobile application, the documents stored in the file 200 can be listed and confirmed.

You can also use the keyboard function for simple editing of the currently running document.

In addition, among the document files of the fish 200, many functions necessary for presentation can be configured by adding a presentation function and moving forward and backward.

Also, by clicking the movie icon in the mobile application, the video stored in the PC 200 can be played back. In addition to controlling the basic operations such as forward / backward, stop and stop, and the like, And so on.

In addition, music files stored in the PC 200 can be listed by clicking music icons in the mobile application, and playback, stop and volume of the music files can be controlled.

In addition, a function for determining whether or not a plurality of users access through an access point (AP) through a Wi-Fi is added to a mobile application, a single user acts as a gateway through Wi-Fi, You can enable this mobile presenter.

Also, by clicking a photo icon in the mobile application, the photo files stored in the file 200 can be listed and displayed.

You can also launch a web browser by clicking on the Internet icon in the mobile app, remotely surf the web, and download and upload files on the web remotely.

On the other hand, you can add 'Alt + Tab' function of keyboard to easily move between several programs running at the same time.

In addition, since it can be controlled by a mobile device 300 such as a smart phone rather than a general presenter pointer, a variety of flexible GUIs (Graphic User Interface) can be provided.
