1. A computing device which communicates with a playback device according to user input, the computing device comprising:
a display; an input device which receives the user input; a memory which stores a program; a communication interface which communicates with the playback device and a separate server via network; and a processor which executes the stored program to generate control information for controlling the playback device, wherein the program comprises: a first instruction executed by the processor to control the communication interface to receive first device configuration information from the playback device and to receive second device configuration information from the separate server, the first device configuration information being necessary for controlling a hardware included in the playback device, the second device configuration information being necessary for controlling an application being executed in the playback device, each of the received first and second device configuration information comprising interface information used to generate a screen and the control information for controlling functions of the playback device, the interface information comprising a Graphical User Interface (GUI) information which configures a GUI of the screen, the GUI information comprising at least one icon and at least one scrollbar; a second instruction executed by the processor to display the screen on the display according to the interface information; a third instruction executed by the processor to receive the user input received from the input device to select one of the functions according to the displayed screen; a fourth instruction executed by the processor to use the received user input to generate the control information for the selected function for controlling the playback device, the fourth instruction comprising a sub-instruction for generating screen mapping information for mapping the screen to a display device connected to the playback device; and a fifth instruction executed by the processor to control the communication interface to transmit the generated control information to the playback device, wherein the interface information further comprises a key-map information including information on each icon displayed in the GUI, each icon corresponding to one of the functions of the control information, wherein the first and second device configuration information includes the GUI information and the key-map information necessary for controlling a JAVA application being executed in the playback device, wherein the key-map information corresponds to a PLAY icon, a STOP icon, a FF icon and a REW icon, which are provided to play video/audio data stored in a blu-ray disk inserted in the playback device, wherein when the PLAY icon displayed on the display of the computing device is clicked by the user input, the processor of the computing device generates the control information by extracting a key input information corresponding to the PLAY icon from the key-map information, wherein when the at least one scrollbar displayed on the display of the computing device is clicked by the user input, the processor of the computing device generates the control information including the key input information corresponding to the at least one scrollbar extracted from the key-map information and a screen mapping information for mapping a scroll of the screen according to the clicking of the at least one scrollbar to a display device connected to the playback device, wherein the first device configuration information is also received from the separate server, and when the first and second device configuration information are received from the separate server via the network, the processor of the computing device does not execute the first instruction. |
