1st Example

A first embodiment of a remote system control method according to the present invention will be described with reference to FIG. 3 is a view showing the display trend of the remote system and the mobile terminal in the remote system control method according to the first embodiment of the present invention.

In the state where the remote system 100 is in the desktop state and the remote system 100 and the mobile terminal 300 are connected to each other through remote control software, the remote system 100 as the mobile terminal 300. Suppose you want to control a remote).

The remote system 100 transmits various types of information (eg, various menus) on the background screen to the mobile terminal 300 in the form of text as shown in (3-1a) of FIG. 3.

Then, the mobile terminal 300 displays the display information of the remote system such as (3-1b) of FIG. 3 in text form. In this case, assume that the terminal user selects "start" from the display information of the mobile terminal 300 through the terminal input unit 360.

Then, the mobile terminal 300 transmits the information that the terminal user has selected the "start" to the remote system 100. Accordingly, the remote system 100 displays the screen conversion according to the "start" menu selection as shown in (3-2a) of FIG. The remote system 100 transmits the information according to (3-2a) of FIG. 3 to the mobile terminal 300 in text form.

Then, the mobile terminal 300 displays the display information of the remote system such as (3-2b) of FIG. 3 in text form. In this case, assume that the terminal user selects "all programs" from the display information of the mobile terminal 300 through the terminal input unit 360.

Then, the mobile terminal 300 transmits to the remote system 100 that the terminal user has selected the "all programs". Accordingly, the remote system 100 displays the screen conversion according to the "program" menu selection as shown in (3-3a) of FIG.

Therefore, there is an advantage that can be much faster in controlling the remote system with a mobile terminal.

Second Example

A second embodiment of a remote system control method according to the present invention will be described with reference to FIG. 4 is a view showing the display trend of the remote system and the mobile terminal in the remote system control method according to a second embodiment of the present invention.

In the second embodiment, while the remote system 100 and the mobile terminal 300 are interconnected through the remote control software, another program (hereinafter referred to as "A program") is executed while the remote system is running. Suppose you want to add a program (hereinafter referred to as "B program") to run it.

In this case, the remote system 100 first opens a window for executing the A program (hereinafter referred to as "WIN A"), as shown in (4-1a) of FIG. 4, wherein the WIN A is the A program. Display the relevant content A1. In addition, the remote system 100 transmits the content A1 of the WIN A to the mobile terminal 300, the content A1 of the WIN A in the terminal display unit 310 is shown in (4-1b) of FIG. Display as shown. The above contents A1 will gradually change to A2, A3, A4, ..., etc. as time passes.

On the other hand, if a terminal user instructs the user to further execute the B program through the proper operation of the terminal input unit 310, the command is transmitted from the mobile terminal 300 to the remote system 100, the remote system As shown in (4-2a) of FIG. 4, the operation 100 opens a window for executing the B program (hereinafter referred to as "WIN B") while executing the B program. The WIN B displays contents B2 related to the B program. This means that the WIN B is activated while the WIN A is deactivated.

The remote system 100 transmits only the contents of the activated window, that is, the contents B2 of the WIN B to the mobile terminal 300. That is, even when the content of the WIN A is changed from A1 to A2 when the WIN B is activated, the remote system 100 does not transmit the content A2 to the mobile terminal 300. Accordingly, the mobile terminal displays the content B2 of the WIN B as shown in (4-2b) of FIG. 4, but does not display the content A2 of the WIN A.

This is the same also in (4-3a) and (4-3b) of FIG. As shown in (4-3a) of FIG. 4, even if the contents of WIN A and WIN B are changed from A2 to A3 and B2 to B3 in the remote system 100, the WIN B is in the remote system 100. Since it is activated, the remote system 100 transmits only the content B3 of the WIN B to the mobile terminal. Accordingly, the mobile terminal displays the content B3 of the WIN B as shown in (4-3b) of FIG. 4, but does not display the content A3 of the WIN A.

Then, as shown in (4-4a) of Figure 4, the remote system 100 receives the command to activate the WIN A from the mobile terminal 300 to activate the WIN A and at the same time the WIN B Deactivate. And even if the contents of WIN A and WIN B are changed from A3 to A4 and B3 to B4 in the remote system 100, the remote system 100 is activated because the WIN A is activated. 100 transmits only the content A4 of the WIN A to the mobile terminal. Accordingly, the mobile terminal displays the content A4 of the WIN A as shown in (4-4b) of FIG. 4, but does not display the content B4 of the WIN B.

As described above, according to the second embodiment, only the contents of the activated window of the remote system are transmitted to the mobile terminal, and the contents of the inactive window are not transmitted to the mobile terminal. Therefore, the amount of data transmitted between the remote system and the mobile terminal can be reduced, and therefore, there is an advantage that it can be much faster in controlling the remote system with the mobile terminal.

Third Example

A second embodiment of a remote system control method according to the present invention will be described with reference to FIG. 5 is a flowchart illustrating a remote system control method according to a third embodiment of the present invention.

The remote system and the mobile terminal are interconnected for remote control [S51]. The mobile terminal then starts to remotely control the remote system [S52].

Then, the mobile terminal measures the signal transmission rate from the remote system at any time or when the reception environment (for example, handover) is changed [S53]. The signal transmission rate may be measured in various ways, but the signal transmission rate may be determined by measuring the electric field reception strength of the mobile terminal.

Next, the mobile terminal determines whether the reception strength is greater than or equal to a predetermined lower limit threshold [S54]. If the reception strength is lower than the lower limit threshold, the mobile terminal requests to transmit low quality data to the remote system [S55]. In other words, if the data is video data, for example, and is being transmitted in 16-bit color, it is required to reduce the quality of the color from 16 bits to 8 bits.

In addition, the mobile terminal determines whether the reception strength is greater than or equal to a predetermined upper limit threshold [S56]. If the reception strength is greater than or equal to the upper limit threshold, the mobile terminal requests to transmit high quality data to the remote system [S57]. That is, if the data is video data, for example, and is being transmitted in 16-bit color, it is required to increase the quality of the color from 16 bits to 8 bits.

Thus, the remote system and the mobile terminal adjust the quality of the data transmitted between them according to the signal transmission rate therebetween. Therefore, when the signal transmission rate is bad, the data quality is lowered to speed up the signal transmission, and when the signal transmission rate is good, there is an advantage that high quality data can be transmitted.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. For example, the above embodiments may be applied separately, but one or more of them may be used in combination with each other. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.

Referring to the remote system control method according to the present invention described above and the effects of the terminal for it are as follows.

Conventionally, there are many limitations in terms of speed and the like for remotely controlling a remote system with a mobile terminal. However, according to the present invention, it is possible to considerably improve the problems of the conventional speed by transmitting display information as text, transmitting only information of a currently active window, or adjusting data quality according to a signal transmission rate as necessary. There is this.
