Information 92 and 94 for guiding the execution of content transmission may include an icon 91 for performing content transmission and information 93 for guiding a user input method for performing content transmission.

9 (a), the control unit 180 displays an icon 97 indicating all contents transmission cancellation in the second area of the chat room displayed on the display unit 151, An icon 98 indicating the icon can be displayed.

Referring to FIG. 7 again, the control unit 180 shares the pending content with other devices connected to the same wireless communication according to user selection (S505).

Referring to FIG. 8A, the controller 180 may display a first content preview screen C1 displayed in a second area of the display unit 151, The transmission of the first content can be canceled according to the step S1. At this time, the controller 180 can perform the second content transmission according to a predetermined time without inputting the user's touch to tap the second content preview screen C2 displayed in the second area.

8 (b), the control unit 180 displays the second content preview screen C2 displayed on the second area of the display unit 151 according to the user touch input The second content can be transmitted. At this time, the controller 180 can cancel the first content transmission after a predetermined time has elapsed without inputting the user's touch to tap the first content preview screen C1 displayed in the second area.

9 (a), the control unit 180 displays a user touch input for selecting an icon 98 indicating all content transmission performed in the second area of the display unit 151 The first content and the second content can be transmitted.

9B, after the transmission of the first and second contents is completed, the control unit 180 displays a first content preview screen C1 and a second content preview screen C1 in the second area of the display unit 151, 2 content preview screen C2 and can display the time information 77 and 79 on which the first content and the second content are transmitted, respectively. At this time, the first content preview screen (C1) and the second content preview screen (C2) displayed in the chat room second area are displayed on the display unit of the other device as well as the terminal (100) Content sharing is possible.

When the user uploads the shared content to the social networking service (SNS), information about the content creation date and time, the user of the device on which the content is generated, and the content creation location can be automatically uploaded. That is, when content is uploaded, the content metadata generated together with the content can also be uploaded.

10 and 11, an operation method of the terminal in the eigenmode release according to the embodiment of the present invention will be described.

FIG. 10 is a flowchart illustrating an operation method according to an embodiment of the present invention in accordance with the release of a shared mode of a terminal.

Referring to FIG. 10, after the wireless communication connection provided in the specific space, the controller 180 cancels the wireless communication connection provided in the specific space (S701).

When the wireless communication connection provided in the specific space is released, for example, when the terminal 100 is located in a space other than the specific space where the wireless communication is provided, when the wireless communication connection is released according to the user's selection, A case where a predetermined period of time has elapsed without transmitting a message or contents using a message, and the like, but the present invention is not limited thereto. Next, the notification of the release of the sharing mode of the terminal 100 when the wireless communication connection is released will be described with reference to FIG.

11 is a diagram illustrating a terminal screen displayed with a notification of a release of a shared mode according to an embodiment of the present invention.

Referring to FIG. 11A, when the wireless communication connection is released, the control unit 180 displays information 201 indicating that the sharing mode is released, a user selection icon 203, popup form.

The information 201 indicating that the sharing mode is released may mean information informing that the chatting room connection is canceled.

When the user selection icon 203 is selected, the control unit 180 can stop displaying the information 201, the user selection icon 203, etc., indicating that the pop-up sharing mode is released on the display unit 151.
