4 is a flowchart illustrating in detail a data transmission flow between a remote controller and a display device according to an embodiment of the present invention. Hereinafter, two embodiments of a data transmission protocol between a remote controller and a display device according to an embodiment of the present invention will be described with reference to FIG. 4.

Before describing FIG. 4, a first embodiment of a data transmission protocol between a remote controller and a display device according to an embodiment of the present invention will be described. First, a remote controller to which an external memory such as an SD card is connected is designed to transmit all of at least one or more contents itself stored in the external memory to a display device. In addition, the user has an advantage of immediately executing any one of the data of the memory downloaded to the display device using the remote controller.

However, according to the first embodiment, since contents stored in an external memory such as an SD card are transmitted to the display device at one time, it may take considerable time for all data transmission to be completed. Furthermore, there is a risk of transmitting data that the user does not want. A second embodiment for supplementing the disadvantages of the first embodiment will be described in detail later with reference to FIG. 4.

Assume that an SD card is connected through a slot, an interface, or the like of a remote controller (S401). At this time, the remote controller and the display device proceed with the setup process capable of wireless communication (S402). For example, the remote controller may transmit a communication connection request signal to the display device and receive a response signal. More specifically, for example, it may be assumed that Wifi Direct communication is connected.

The above-described remote controller does not transmit all the data stored in the SD card to the display device at once, but transmits a list for identifying each of the data stored in the memory such as the SD card to the display device (S403). The list may, for example, be designed to include only title information identifying each piece of content.

On the other hand, the display device is designed to output the received list on the screen (S404). Furthermore, the user who has confirmed the list output on the screen of the display device can select specific data using the remote controller (S405). In addition, in step S404, it is assumed that the list is output on the screen of the display device, but may be designed to be displayed on a remote controller having a display module as required by those skilled in the art. More specific embodiments related to this will be described later in detail with reference to FIGS. 5 to 10.

The above-described remote controller transmits only the specific data selected by the user to the display device (S406), and the display device downloads the specific data to the memory (S407). Then, the corresponding data is displayed from the time when the download is completed or when the A / V output is possible (S408).

That is, in the case of designing as shown in FIG. 4 described above, in the initial process, only the list is sent, and the data is transmitted only when the user selects specific content, thereby solving the problem of inefficiency of unnecessary data transmission and processing speed. There is a technical effect to improve the.

Meanwhile, the embodiment described in FIG. 4 will be described as follows.

A control method of a remote controller capable of communicating with a display device designed according to an embodiment of the present invention may include setting up wireless communication with the display device when at least one memory is connected through a reader, and at least one stored in the memory. Transmitting a list identifying each of the above data to the display device, if an ID identifying the specific data among the at least one or more data on the list is selected, loading the selected specific data from the memory, and the loading Transmitting the completed specific data to the display device.

According to another embodiment of the invention, the step of receiving at least one or more of the data stored in the display device via a wireless communication module, and transferring the received specific data to the memory connected to the reader And controlling the transfer of the specific data to be stored in the memory.

According to another embodiment of the present invention, the method further comprises the steps of: displaying a list identifying each of the at least one data stored in the memory, and transmitting the specific data having been loaded to the display device. And displaying the time required or the degree of completion. Further, the degree of completion means a relative value compared to the number of data packets that are currently being transmitted, for example, based on the total number of data packets to be transmitted. In this regard will be described later in detail with reference to FIG.

The reader described above includes, for example, an interface into which a secure digital (SD) card is inserted.

5 is a diagram illustrating the first-first step of controlling the display device by the remote controller according to an embodiment of the present invention. Hereinafter, a first process of outputting the list described above with reference to FIG. 5 on the screen of the display device will be described.

First, as shown in FIG. 5, the display device 550 according to an exemplary embodiment outputs a general broadcast screen 551. Of course, although the broadcast screen of channel 11 is illustrated in FIG. 5, the broadcast screen 551 may be replaced with a screen on which an application is executed or a screen on which a web page is executed.

At this time, it will be assumed that the external memory 501 is inserted into the remote controller 500 according to an embodiment of the present invention. As described above, the external memory 501 corresponds to an SD card, for example. Further, the remote controller 500 may be implemented by those skilled in the art with reference to FIG. 2 or FIG. 3 described above.

In addition, when the external memory 501 is connected to the remote controller 500, the wireless communication module of the remote controller 500 displays a list for identifying each of at least one or more data stored in the external memory 501. To).

Accordingly, the display device 550 displays a list 552 for identifying each of the data stored in the external memory 501 together with the current broadcast screen 551 on one screen. The user can minimize viewing disturbance on the current broadcast screen, and there is also an advantage of not having to directly connect the external memory to the display device 550.

On the other hand, after assuming FIG. 5, the embodiment of the present invention will be described with reference to Figure 6 below.

FIG. 6 is a diagram illustrating steps 1-2 in which a remote controller controls a display device according to an embodiment of the present invention. Hereinafter, a second process of outputting the list described above with reference to FIG. 6 on the screen of the display device will be described.

First, as shown in FIG. 6, the display device 650 according to an embodiment of the present invention outputs the current broadcast screen 651 as it is and simultaneously stores data stored in the external memory 601 (for example, an SD card). Display a list 652 identifying each.

In this case, the user may select specific data or content desired by the user using the remote controller 600 according to an embodiment of the present invention. For example, a push button of the remote controller 600 shown in FIG. 6 may be used, or as described in FIG. 3, a method of changing the position of the remote controller 600 may be adopted.

That is, the position of the indicator 653 is designed to be changed according to the push button or the motion of the remote controller 600 described above. In FIG. 6, it is assumed that the first content on the list 652 is selected by selecting the push button indicating the left arrow direction of the remote controller 600.

Meanwhile, after assuming FIG. 6, an embodiment of the present invention developed thereafter will be described with reference to FIG. 7.

FIG. 7 illustrates steps 1-3 of a remote controller controlling a display device according to an embodiment of the present invention. Hereinafter, a third process of outputting the list described above with reference to FIG. 7 on the screen of the display device will be described.

Unlike FIG. 5 and FIG. 6 described above, the display device 750 shown in FIG. 7 stops outputting a broadcast screen and executes a first content among data stored in an external memory 701 connected to the remote controller 700. The displayed screen 755 is output. Of course, in FIG. 7, it is assumed that the list disappears completely. However, in order to increase the user's convenience, the list identifying each of the contents stored in the external memory may be continuously displayed.

In FIG. 5 to FIG. 7, it is assumed that a list for identifying data stored in an external memory (for example, an SD card) is output on a display device. Designed to be output is also within the scope of the present invention. This will be described later in detail with reference to FIGS. 8 to 10.

FIG. 8 is a diagram illustrating steps 2-1 in which a remote controller controls a display device according to another embodiment of the present invention. Hereinafter, the first process of displaying the list described above with reference to FIG. 8 on the remote controller itself will be described.

As shown in FIG. 8, even when the external memory 801 is connected to the remote controller 800 according to another embodiment of the present invention, the broadcast screen 851 of the display device 850 is maintained as it is. In FIG. 5, the list and the broadcast screen partially overlap.

On the other hand, since the remote controller 800 shown in FIG. 8 has a display module, a list 802 for identifying each of the data retrieved from the external memory 801 is immediately displayed.

Since the list does not need to be transmitted to an external device (for example, the display device 850), it is advantageous in terms of data processing speed and has an advantage in that the broadcast screen is maintained as it is. Of course, FIG. 5 is advantageous in that the user can select specific content by checking only the screen of the display device.

On the other hand, after the assumption of Figure 8, the embodiment of the present invention will be described with reference to Figure 9 below.

9 is a diagram illustrating steps 2-2 in which a remote controller controls a display device according to another embodiment of the present invention. Hereinafter, a second process of displaying the list described above with reference to FIG. 9 on the remote controller itself will be described.

First, as shown in FIG. 9, the display device 950 is designed to continuously output the current broadcast screen 951 until a specific content is selected. Of course, the case of outputting other video data instead of the broadcast screen 951 is also within the scope of the present invention.

At this time, the user who has confirmed the list 902 output on the display of the remote controller 900 connected to the external memory 901 can select the specific content (for example, the third content) by touching it. Of course, the use of the push button instead of the touch pad is also within the scope of the present invention.

Accordingly, the remote controller 900 transmits only the specific content (third content) selected by the user among at least one or more data stored in the external memory 901 to the display device 950.

Meanwhile, after assuming FIG. 9, an embodiment of the present invention that will be developed thereafter will be described with reference to FIG. 10.

FIG. 10 is a diagram illustrating steps 2-3 in which a remote controller controls a display device according to another embodiment of the present invention. Hereinafter, a third process of displaying the list described above with reference to FIG. 10 on the remote controller itself will be described.

8 and 9, the display device 1050 shown in FIG. 10 stops outputting a broadcast screen and executes third content among data stored in the external memory 1001 connected to the remote controller 1000. The displayed screen 1055.

Furthermore, the remote controller 1000 according to another embodiment of the present invention provides a graphic 1002 for monitoring a data transmission process on a display. For example, based on the total number of data packets to be transmitted, the relative value of the number of data packets being transmitted is displayed.

More specifically, for example, it is designed to include at least one of the first indicator 1003 indicating the degree of completion of the transmission or the second indicator 1004 indicating the time remaining until the transmission is completed. Therefore, the user can check the transmission state of the data stored in the external memory only by checking the display of the remote controller.

In this specification, although FIGS. 1 to 10 are described for convenience of description, it is obvious that other embodiments are implemented by combining some of the features of each drawing to belong to the scope of the present invention.
