Display apparatus and control method thereof

A control method of a display apparatus, the control method comprising:

• communicating with a plurality of devices comprising a first device that stores content data and a second device that stores an application to process the content data, the first device and the second device being devices external to the display apparatus;
• displaying a first user interface (UI) image corresponding to the first device and a second UI image corresponding to the second device;
• receiving a command to process the content data by the application through the first UI image and the second UI image;
• and
• controlling a processing operation of the application with respect to the content data based on the command,
• wherein the first UI image displays a list of content files stored in the first device,
• the second UI image displays an execution view of the application for editing the content files, and
• the controlling the processing operation comprises:
• in response to receiving a first user input selecting at least one of the content files through the first UI image, controlling the first device to transmit the selected content file to the second device,
• in response to receiving a second user input to manipulate the processing operation of the application through the second UI image, controlling to transmit a first control signal to the second device such that the application edits the selected content file based on the first control signal, and
• in response to receiving a third user input designating at least one of the plurality of devices, controlling to transmit a second control signal to the second device such that the second device transmits the edited content file to a designated device.

An apparatus comprising:

• a communication interface configured to communicate with a plurality of devices comprising a first external device and a second external device;
• a hardware processor being configured to obtain data for generating a first user interface (UI) image including a list of content files stored in the first external device and a second UI image including an execution view of an application for editing the content files, the application being stored and executed in the second external device;
• and
• a display device which is configured to display the first UI image and the second UI image,
• wherein the hardware processor is further configured:
• in response to receiving a first user input selecting at least one of the content files through the first UI image, to control the first external device to transmit the selected content file to the second external device,
• in response to receiving a second user input to manipulate a processing operation of the application through the second UI image, to control the communication interface to transmit a first control signal to the second external device such that the application edits the selected content file based on the first control signal, and
• in response to receiving a third user input designating at least one of the plurality of devices, to control the communication interface to transmit a second control signal to the second external device such that the second external device transmits the edited content file to a designated device.
