Abstract

A mobile terminal for providing a video sharing function in a multi-party call state and its video sharing method are disclosed. When a video sharing menu is selected while a user is performing individual call communication or multi-party call communication, one or a plurality of video share keys in relation to a user selected for video sharing are displayed, so that the user can select a desired one of the displayed video share keys to share video with the selected user. In addition, a video share authority change key is disposed on the screen of a terminal set as a video share authority (chief authority) change target, so that a corresponding terminal can select the video share authority change key during individual or multi-party video sharing to acquire the authority of video sharing (chief authority) from a terminal currently having the authority of video sharing, thus perform bi-directional video sharing in real time.

performing, by the mobile terminal, the video sharing with at least one of the plurality of users using the video share key,

wherein the video share key includes one or more individual video share keys or a single multi-video share key, and

wherein the one or more individual video share keys are automatically integrated into the single multi-video share key when a number of users who are available to share the video exceeds a certain number.

2. The method of claim 1, further comprising:

when a video sharing menu is selected during the multi-party call communication, displaying a menu for setting a target for the video sharing and user information.

3. The method of claim 1, wherein a number of the one or more individual video share keys is consistent with the number of users who are available to share the video.

4. The method of claim 1, wherein the one or more individual video share keys are added or deleted.

5. The method of claim 4, wherein the one or more individual video share keys are deleted when the one or more individual video share keys are moved by a certain distance to the left or right through touch-and-dragging or flicking.

6. The method of claim 4, wherein the one or more individual video share keys are added in one of an upward or downward direction of the displayed video share key through a menu selection.

7. The method of claim 1, wherein the one or more individual video share keys are set to be automatically deleted when the video sharing is terminated.

8. The method of claim 1, wherein the one or more individual video share keys are integrated into the single multi-video share key through user'"'"'s touch-and-dragging or flicking.

9. A mobile terminal, comprising:

a memory configured to store information in relation to a video sharing of a video;

a display unit configured to display information in relation to the video sharing and a video shared state; and

a controller configured to

display a video share key in relation to a plurality of users when the video sharing is performed during a multi-party call communication, and

perform the video sharing with at least one of the plurality of users using the video share key,

wherein the video share key includes one or more individual video share keys or a single multi-video share key, and

wherein the one or more individual video share keys are automatically integrated into the single multi-video share key when a number of users who are available to share the video exceeds a certain number.

10. The mobile terminal of claim 9, wherein when the video sharing is selected during the multi-party call communication, the controller displays items for selecting a user for transmitting video and user information on the display unit, and displays information corresponding to the user selected from the items and the video share key on the display unit.

11. The mobile terminal of claim 9, wherein a number of the one or more individual video share keys is consistent with the number of users who are available to share video, and the one or more individual video keys can be added or deleted.

12. The mobile terminal of claim 11, wherein the one or more individual video share keys are deleted when the one or more individual video share keys are moved by a certain distance to the left or right through touch-and-dragging or flicking.

13. The mobile terminal of claim 11, wherein the one or more individual video share keys are added in one of upward and downward directions of the displayed video share key through a menu selection.

14. The mobile terminal of claim 9, wherein the one or more individual video share keys are set to be automatically deleted when the video sharing is terminated.

15. The mobile terminal of claim 9, wherein the one or more individual video share keys are integrated into a single multi-video share key through a user'"'"'s touch-and dragging or flicking.

16. A video sharing method of a mobile terminal, the method comprising:

performing, by the mobile terminal, a multi-party call communication with a plurality of terminals;

displaying, by the mobile terminal, a video share key in relation to the plurality of terminals on the mobile terminal when a video sharing of a first video is selected during the multi-party call communication;

performing, by the mobile terminal, the video sharing of the first video with at least one of the plurality of terminals using the video share key;

registering, by the mobile terminal, one of the plurality of terminals as a video share target by the mobile terminal so that a video sharing authority change key is displayed only on a screen of the one of the plurality of terminals;
