Mobile terminal, display apparatus and control method thereof

A control method of a handheld device for performing a video communication, the control method comprising:

• controlling to perform a video communication with another handheld device through a cellular communication interface by sending video data toward the other handheld device and receiving video data originating from the other handheld device;
• controlling to send, toward the other handheld device, a selection of a content to be displayed in the other handheld device during the video communication to cause the selected content to be displayed in the other handheld device, wherein the content is stored in the other handheld device;
• controlling to provide video data in a first display area of the touch display and provide the selected content in a second display area of the touch display based on the selection during the video communication;
• controlling to receive first handwritten information originating from the other handheld device as data separate from the selected content, wherein the first handwritten information is associated with the selected content;
• controlling to provide the selected content and the received first handwritten information together in the second display area during the video communication based on association between the selected content and the received first handwritten information;
• and
• controlling to send, toward the other handheld device, second handwritten information inputted in the second display area in which the selected content and the received first handwritten information are provided together during the video communication as data separate from the selected content, wherein the second handwritten information is associated with the selected content,
• wherein video data, the first handwritten information, the second handwritten information, and the content are communicated through the same cellular communication interface.

A non-transitory computer readable recording medium storing instructions executable by a processor of a handheld device for performing a video communication to cause the processor to at least:

• control to perform a video communication with another handheld device through a cellular communication interface by sending video data toward the other handheld device and receiving video data originating from the other handheld device;
• control to send, toward the other handheld device, a selection of a content to be displayed in the other handheld device during the video communication to cause the selected content to be displayed in the other handheld device, wherein the content is stored in the other handheld device;
• control to provide video data in a first display area of the touch display and provide the selected content in a second display area of the touch display based on the selection during the video communication;
• control to receive first handwritten information originating from the other handheld device as data separate from the selected content, wherein the first handwritten information is associated with the selected content;
• control to provide the selected content and the received first handwritten information together in the second display area during the video communication based on association between the selected content and the received first handwritten information;
• and
• control to send, toward the other handheld device, second handwritten information inputted in the second display area in which the selected content and the received first handwritten information are provided together during the video communication as data separate from the selected content, wherein the second handwritten information is associated with the selected content,
• wherein video data, the first handwritten information, the second handwritten information, and the content are communicated through the same cellular communication interface.
