For example, it means that it can be executed by a server which is an external device, but can not be executed by the mobile terminal 100. When a server serving as an external device is a server providing various applications and / or contents, a part of various contents stored in the server may not be executed in the mobile terminal 100. The mobile terminal 100 according to an embodiment of the present invention can selectively convert content that can not be executed in the mobile terminal 100. [

Converting may be a process of changing content from a first format to a second format. For example, it may be executable in the server in the first format, but may not be executable in the mobile terminal 100. In this case, the process of changing the content may be performed in a second format that can be executed by the mobile terminal 100, and the process may be converting.

In order for conversion to proceed, a certain amount of resources may be required. For example, a certain amount of memory or the like may be required to facilitate the conversion. The mobile terminal 100 according to an embodiment of the present invention can determine the location where the conversion is to be performed by taking into consideration the resources, the communication state, and the like in a comprehensive manner. For example, if a large amount of system resources are required for conversion, the server can perform conversion, and if the data capacity increases after conversion, the conversion can be performed in the mobile terminal 100.

The control unit 180 that has checked the terminal status can operate the mobile terminal 100 in the first mode S20 or the second mode S40.

If the first mode S20 is performed, step S30 of acquiring the converted content may be performed.

The content may be located in another terminal (200 of FIG. 5). For example, it may be located on an external server. The external server may be a content server including storage storing various contents.

Other terminals (200 in FIG. 5) including the server may be storing various contents. At least some of the contents stored in another terminal (200 of FIG. 5) may have a file format that is not supported by the mobile terminal 100. For example, it means that the moving image can not be reproduced by the mobile terminal 100 or the document can not be displayed because it is not supported by the mobile terminal 100.

The control unit 180 may cause the mobile terminal 100 to operate in the first mode according to the terminal status.

The first mode may be a mode in which conversion for the content is performed in another terminal (200 in Fig. 5). That is, in the mobile terminal 100, the content that can not be reproduced can be played, displayed, or executed in the mobile terminal 100, (200 in FIG. 5).

The control unit 180 can determine the progress of the first mode based on the terminal status. For example, if the transmission speed of the wireless communication through the wireless communication module 113 is low, the mobile terminal 100 can operate in the first mode. Alternatively, the mobile terminal 100 can operate in the first mode when the capacity of the content is large and the capacity can be reduced when converting. Alternatively, when the control unit 180 of the mobile terminal 100 is performing another task, the control unit 180 may operate in the first mode. Alternatively, the mobile terminal 100 may operate in the first mode when the memory 160 of the mobile terminal 100 is small. In addition, if it is effective to convert from another terminal (200 in FIG. 5) than to convert from the mobile terminal 100, it may enter the first mode.

The control unit 180 may cause the mobile terminal 100 to operate in the second mode (S40, S50, S60) according to the terminal status.

The second mode may be a mode for allowing the mobile terminal 100 to convert the content. That is, the step of acquiring contents from another terminal (200 of FIG. 5) (S50) may proceed first. Converting the acquired content after obtaining the content (S60) may proceed.

In the second mode, conversion for the content may be performed in the mobile terminal 100. That is, when the acquired content is content that can not be reproduced in the mobile terminal 100, it means that the control unit 180 can convert the content. For example, if the wireless environment in the area where the user is located is good and the transmission speed is higher than usual, the content can be quickly acquired and converted before the user gets out of the area. Alternatively, if the capacity of the content is expected to increase in the case where conversion for the content is made, the content may be converted after it is acquired.

A step S70 of reproducing the content in the mobile terminal 100 may be performed.

The content may be converted at another terminal (200 of FIG. 5) or at the mobile terminal (100). The converted content can be reproduced in the mobile terminal 100. [

5 is a view for explaining a conversion position of contents.

The control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can allow the content C to be converted at the other terminal 200 or converted at the mobile terminal 100 .

The content C may be stored in the other terminal 200. The other terminal 200 may be, for example, a server for storing a large amount of content C and serving content C stored in a plurality of mobile terminals 100. Alternatively, the other terminal 200 may be a mobile terminal used by another user. The content C stored in the server of the server and / or another user may be in a form that the mobile terminal 100 does not support. For example, it means that OS A is supported and executable content, but OS B does not.

It may be necessary to convert the content C in the case of the content C in a form that can not be reproduced by the mobile terminal 100. [ The control unit 180 of the mobile terminal 100 according to an embodiment of the present invention can determine a location to be converted based on the terminal status.

Once the converting position has been determined, conversion to content C can be done accordingly. For example, conversion may be sent to the mobile terminal 100 after it is performed in the converter 285 of another terminal. Alternatively, conversion may be performed at the converter 185 of the mobile terminal after the content is transmitted to the mobile terminal 100. The converted content C can be displayed through the display 151 of the mobile terminal 100 or the like.

The other terminal 200 may be a server or another mobile terminal as described above. Alternatively, the other terminal 200 may be a terminal coupled to the mobile terminal 100 via a local area communication method such as Bluetooth or coupled to a USB port of the mobile terminal 100.

Figure 6 is an illustration of the content embodied at the converting position of the content of Figure 5;

As shown in the figure, the first terminal 200 may store the first image content C1. The first image content C1 stored in the other terminal 200 may not be able to be reproduced by the mobile terminal 100. [ For example, the mobile terminal 100 can not reproduce the image file in the format having the pic extension.

The control unit 180 determines whether the conversion from the converter 285 of the other terminal 200 or the converter 185 of the mobile terminal 100 is performed when the first image content C1 can not be reproduced from the mobile terminal 100 It is possible to proceed.

When the conversion is performed, the first image content C1 can be converted into the second image content C2. For example, it means that an image file with the extension pic can be converted to an image file with the extension bmp format. The converted second image content C2 can be displayed on the display image (DC) through the display 151 of the mobile terminal 100. [

FIG. 7 is a diagram illustrating a terminal status of the mobile terminal of FIG.

As shown in the figure, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention can determine a location where conversion will be performed according to the terminal status.

The terminal status includes at least one of a load status of the controller 180, a status of the memory 160, a status of communication with the server, a size of the content, a size of the content, Whether or not it has been converted, and the time required for conversion.

The load state of the control unit 180 may indicate a state of a task performed by the control unit 180 of the mobile terminal 100. [ For example, if the control unit 180 is currently performing a specific task, the control unit 180 may not be able to perform the conversion smoothly. On the other hand, if the load is low because the controller 180 is not currently performing a special task, the conversion can be smoothly performed through the controller 180 as well. Accordingly, the control unit 180 can determine the position at which the conversion is to be performed according to the load state of the control unit 180. [

The state of the memory 160 may indicate whether the memory 160 of the mobile terminal 100 is occupied by another application. For example, if another application is executed and there is no room in the memory 160, the conversion in the mobile terminal 100 may not be smooth.

The communication state with the server may mean the communication speed between the mobile terminal 100 and a server that is one of the other terminals 200. [ For example, suppose that a speed of 1 occurs in a normal radio environment, and if a speed of 1.5 now comes out, it may be desirable to receive the content at the present time quickly. On the other hand, if the current speed is 0.5, the server can perform the conversion and receive the converted content when the normal transmission speed comes out later.

The size of the content may mean the size of the content to be transmitted. For example, if the size is larger than a certain standard, it means that the terminal 200 is converted at the other terminal 200, and if it is smaller than that, it is converted at the mobile terminal 100.

The size change of the content may mean a change in the content size before and after the conversion. For example, if the size of the content increases by converting, it may be preferable to convert the content from the mobile terminal 100 after acquiring the content first.

The type of the content may mean the format of the content. For example, in the case of a moving image capable of being displayed in a streaming manner, it may be possible to perform conversion at the other terminal 200 and display the same at the mobile terminal 100. On the other hand, in the case of a still image that can be displayed only after the conversion for the entire specific content is completed, the converted content can be transmitted and converted in the mobile terminal 100.

The location where conversion is to be performed may be determined depending on whether the mobile terminal 100 has a converter. That is, if there is no converter capable of converting the content into the mobile terminal 100, it means that conversion can be performed in the other terminal 200. [ For example, if the mobile terminal 100 does not have a converter capable of changing a file having an extension pic to a bmp file that can be displayed on the mobile terminal 100, (Not shown).

The conversion required time may mean a time required for an operation of converting the content. For example, when the conversion time is expected to be short, conversion is performed in the mobile terminal 100, and conversions can be performed in the other terminals 200 when the conversion time is expected to be long.

8 and 9 are signal flow diagrams illustrating the operation of the mobile terminal of FIG.

As shown in FIG. 8, the mobile terminal 100 may check the terminal status (S10) and request the content converted to the other terminal 200 (S2). For example, when the current radio wave condition is below the reference value, the control unit 180 is under load, the memory 160 is allocated to another application, the state where the size of the content is expected to decrease when converted, It means that the control unit 1800 can request conversion to the other terminal 200 when there is at least one of a state in which the corresponding converter is not present in the terminal 100 and a state in which conversion is expected to take a long time.

The other terminal 200 that has requested the conversion of the content may convert the content (S25) and transmit the converted content to the mobile terminal 100 (S30). The mobile terminal 100 can reproduce the converted content (S70).

As shown in FIG. 9, the mobile terminal 100 which has checked the terminal status (S10) can request the content to the other terminal 200 (S42) and transmit the unconverted content (S50). The mobile terminal 100 can convert the acquired content (S60) and reproduce it (S70).

10 is a diagram illustrating an operation of the mobile terminal of FIG.

As shown, the other terminal 200 performs conversion for the content irrespective of the communication state, and the mobile terminal 100 can acquire the converted content when the communication state is good. For example, even when the connection with the other terminal 200 is disconnected and then resumed, the continuously converted content can be obtained.

Conversion may be initiated at t1 and up to t2 at the other terminal 200. [

The mobile terminal 100 can receive the converted content in real time and reproduce it from t3. For example, it means that the converted video from the server can be transmitted and displayed in a streaming form.

The mobile terminal 100 receiving the streaming data in real time can be disconnected from other terminals 200 at time t4. For example, this may mean that the propagation environment may deteriorate.

Disconnection of the transmission can be made up to t5. Even if the transmission is disconnected from t4 to t5, the other terminal 200 can continue to perform the conversion. Therefore, at time t5 when the transmission is resumed, the mobile terminal 100 receives the converting image at time t4, while the other terminal 200 may be converting at time t5. According to an embodiment of the present invention, even when the connection between the mobile terminal 100 and another terminal 200 is interrupted, the mobile terminal 100 can be more conveniently used because the conversion can be performed stably .

FIG. 11 is a diagram illustrating a process of converting an e-mail attachment in the mobile terminal of FIG.

As shown, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention can perform the process of converting the content when the content is not executable in the mobile terminal 100. [

As shown in Fig. 11 (a), e-mail can be received from another user. A particular attachment may be attached to an email. For example, an image file may be attached. The attached image file may not be executable on the mobile terminal 100. That is, the mobile terminal 100 may be attached with a file of a format that can not be executed.

As shown in FIG. 11 (b), if the attached file can not be executed, the control unit 180 determines whether or not the file can be converted. If the file can be converted, the control unit 180 may display a message have. The user can proceed with the conversion if desired. Although the figure shows the case where the e-mail application is executed for the sake of understanding, the above-described procedure can be performed in the SMS message, the SNS message, and the like.

[ The server S may store various contents. At least some of the various contents stored in the server S may be used in the mobile terminal 100. [ At least a part of the contents stored in the server S may not be directly used in the mobile terminal 100. [ That is, the format of the content may not be supported by the mobile terminal 100. For example, although the specific content may be stored in the A format in the server S, the mobile terminal 100 may not be able to display and / or execute the A format. In such a case, the mobile terminal 100 according to the embodiment of the present invention may be configured so that the server S or the mobile terminal 100 can display the content of the A format on the mobile terminal 100 and / Format.

As shown in FIG. 13, the mobile terminal 100 can be connected to various devices.

The mobile terminal 100 may be connected to at least one of the USB 200, the personal computer 300, and other mobile terminals 400 as shown in FIG. For example, the USB 200 may be connected to the mobile terminal 100 in the form of being inserted into a port of the mobile terminal 100. The personal computer 300 may be connected to the mobile terminal 100 using a cable. The other mobile terminal 400 may be connected to the mobile terminal 100 wirelessly. That is, the mobile terminal 100 can be connected to various external devices through various means.

FIGS. 14 and 15 are diagrams illustrating a conversion selection process for a specific content.

As shown in these drawings, the control unit 180 of the mobile terminal 100 according to an embodiment of the present invention selects a specific content by a user selection and / or a control operation of the control unit 180 Can proceed.

That is, the mobile terminal 100 can acquire and display the information of the content before acquiring the data of the content itself. The information of the content may include at least one of a format of the content, a kind of the content, a name of the content, and a size of the content. The control unit of the mobile terminal 100 can acquire the information of the content and display it on the display 151. [ At the time when the content information is displayed on the display 151, the data of the content itself may not be transmitted to the mobile terminal 100 yet.

As shown in FIG. 14B, the user can perform an operation of selecting a specific content with the finger F or the like.

As shown in FIG. 15A, when the user selects a specific content, the control unit 180 can determine whether or not conversion of the selected specific content is necessary. The selected specific content may be a usable format in the server but an unusable format in the mobile terminal 100. The control unit 180 may determine whether the selected content is available in the mobile terminal 100 and may display the converting area CA if the format is not available in the mobile terminal 100. [

As shown in FIG. 15 (b), the user can drag the selected content and drop it onto the conversion area CA displayed at a specific point on the display 151. [ When the content is dragged and dropped, the control unit 180 can perform an operation of converting the corresponding content.
