For example, suppose that five display devices (TV1 to TV5) are installed in physically separated spaces in a bookstore. At this time, the mobile communication device can obtain position information of each display device by using the GPS function. Here, the positional information may be acquired when each display device is installed or moved, or may be acquired after the display device is installed. That is, the user moves the mobile communication device to a place where each display device is installed and communicates with the display device to acquire device information (e.g., serial number, display device name, manufacturer name, etc.) To obtain the current location information of the mobile communication device. At this time, the obtained current location information of the mobile communication device is the location information of the display device. This process is performed on one or more display devices to obtain device information and location information of one or more display devices. Then, the network map is constructed using the obtained information. At this time, the network map may be configured directly from the obtained information, or may be configured based on the acquired information, and then the network map may be configured based on the table information. Figure 8 shows an embodiment of a network map. The network map thus configured is stored in the mobile communication device. The network map may also be transmitted to the content editor 200 and further stored in the content editor 200.

In the mobile communication device or the content editor, content can be individually transmitted to each display device based on the network map.

9 is a flowchart showing an embodiment of a method of configuring a network map of a display device using a GPS function (i.e., a GPS module) of a mobile communication device according to the present invention.

That is, the mobile communication device 300 communicates with the display device 100 at a place where the display device 100 is installed, and requests device information including the serial number, name, and the like of the display device 100 (S901) . That is, the device information includes one or more pieces of information that can identify the display device 100.

The display device 100 transmits device information including a serial number and name to the mobile communication device 300 at the request of the mobile communication device 300 (S902). Also, the mobile communication device 300 confirms the current location using the internal GPS module and sets the confirmed current location as the location information of the display device 100 (S903). This process is performed in a place where one or more display devices are installed.

Then, the device information and location information acquired from each display device are stored in a table form (S904). At this time, the device information and the location information may be acquired from the first display device to form a table, and then, the device information and the location information may be updated by another display device. Alternatively, a table may be configured after obtaining device information and position information from all display devices. This will not be described in detail in the present invention due to implementation problems. In response to the user's request, the mobile communication device 300 constructs a network map of the display device based on the table information and displays the network map graphically (S905).

Meanwhile, the table created in the mobile communication device 300 is transmitted to the content editor 200 and stored in the content editor 200 as an embodiment. At this time, the transmission of the table may be transmitted from the mobile communication device 300 to the content editor 200 when the content editor 200 requests it, or when a table is created or updated in the mobile communication device 300 To the content editor 200 automatically. Also, in the content editor 200, a network map of display devices is configured and displayed graphically on the basis of the table information if requested by a user.

10 is a diagram illustrating an example of transmitting a specific content to a specific display device by referring to a network map in a mobile communication device according to the present invention. The transmission process of FIG. 10 may be performed in the content editor 200. FIG. On the screen of the mobile communication device of Fig. 10, an example of a network map including five display devices is shown on the left, and an example of a content list is shown on the right. That is, in order to facilitate identification of each display device, a display device corresponding to TV1 to TV5 in FIG. 10 is displayed with a specific name given by the user. The content list also includes content stored in at least one of a content editor, a network storage such as a NAS, and a mobile storage device such as a USB. The mobile communication device may be provided with a content list in a content editor.

For example, suppose that the display device named "best seller " transmits content related to the best seller among the contents in the content list. In this case, when the user selects a display device named " best seller "in the right network map and selects a content corresponding to the best seller from the left contents list and requests transmission, the selected contents are transmitted only to the display device named" best seller " And reproduced. Conversely, content may be selected first in the content list, then a display device may be selected in the network map, and transmission may be requested. Here, the display device or the content may be selected as an overlapping one embodiment.

At this time, the selected content is directly transmitted from the content editor to the display device. To this end, the mobile communication device transmits information of the selected display device through the network map and information of the selected content through the content list to the content editor and the display device. That is, in the mobile communication device, only the user interface (UI) for displaying the network map and the content list and allowing the user to select the content and the display device is provided, and the actual transmission is performed by the content editor and the display Device.

As described above, the user who is the content producer can quickly and easily perform the editing of the content being played back on the display device by editing the content while sharing the editing screen with the display device in the mobile communication device, Since it can be confirmed in real time, the satisfaction of editing can be increased. Also, the location information of the display devices can be acquired using the GPS function of the mobile communication device, and the network map can be configured based on the location information, thereby facilitating the content transmission and management of each display device.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, .
