0029Certain exemplary embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings.

0030In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the invention. Thus, it is apparent that the exemplary embodiments of the present invention can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the invention with unnecessary detail.

0031<figref idref="f0001">FIG. 1</figref> is a view illustrating a system to which a display apparatus according to an exemplary embodiment of the present invention is applied.

0032Referring to <figref idref="f0001">FIG. 1</figref>, a system comprises an external network 100 and a display apparatus 200. The external network 100 communicates with the display apparatus 200 in a wired or wireless manner and provides various items which can be installed in the display apparatus 200. The item includes a widget, an application, a service, and contents.

0033If the external network 100 provides a widget to the display apparatus 200, the external network 100 comprises a communication network 110, a hub site 120, and a plurality of contents providers (CP) 130, 140 (CP1, CP2). The number of CPs is not limited to two.

0034The hub site 120 is a server which is managed by the manufacturer of the display apparatus 200 to provide various data to users who purchased the products of the manufacturer. The CPs 130, 140 provides a widget to the hub site 120. Accordingly, the hub site 120 receives the widget from the CPs 130, 140 and transmits it to the display apparatus 200.

0035The display apparatus 200 provides a function of communicating with the external network 100 and may be an internet protocol television (IPTV) providing an interactive service, for example. Accordingly, the display apparatus 200 can provide an additional function such as a web-surfing and a widget besides the general TV function.

0036The user downloads an item from the external network 100 and installs it in the display apparatus 200, and stores and registers the installed item. Also, the user can add an item as he/she wishes to install and delete an item which is already installed.

0037As shown in <figref idref="f0002">FIG. 2</figref>, the display apparatus 200 comprises a receiver 205, an interface 210, an audio/video (AV) processor 220, a speaker 230, a user interface (UI) generator 240, a display unit 250, a storage unit 260, a user input unit 270, a remote control receiver 280, and a controller 290.

0038The receiver 205 receives a broadcast signal from a broadcasting station or satellite in a wire or wireless manner and tunes to the broadcast signal. The broadcast signal may include data including news information, weather information and stock information.

0039The interface 210 provides a wire or wireless communication interface with the external network 100 and may use a network interface card. If the user requests a widget to be downloaded, the interface 210 receives the widget through the CP1 130, the hub site 120, and the communication network 110. The external network 100 may be the internet.

0040The AV processor 220 performs signal-processing, such as video decoding, video scaling, and audio decoding, with respect to an AV signal input from the receiver 205 or a moving picture received through the interface 210. Also, the AV processor 220 outputs the video signal to the UI generator 240 and outputs the audio signal to the speaker 230.

0041If the received AV signal is stored to the storage unit 260, the AV processor 220 outputs the AV signal in the compressed format to the storage unit 260.

0042The UI generator 240 generates various UIs to provide them to the user. The UI generator 240 adds the generated UI to the video signal input from the AV processor 220 and outputs the UI to the display unit 250. The UI generated by the UI generator 240 may include a UI showing items which are already installed and items which can be installed, and a UI showing a process of installing a selected item, as shown in <figref idref="f0003 f0004 f0005 f0006">FIGS. 3A to 3D</figref>.

0043<figref idref="f0003 f0004 f0005 f0006">FIGS. 3A to 3D</figref> are views illustrating an example showing a path along which an item is installed in the display apparatus.

0044If a user requests an item to be installed by manipulating the user input unit 270, the interface 210 receives a list of installable items from the external network 100. The UI generator 240 generates a UI showing the received list of installable items and a list of items which are already installed as shown in <figref idref="f0003">FIG. 3A</figref>.

0045Referring to <figref idref="f0003">FIG. 3A</figref>, the UI includes a first area 10 to display items which are already installed or registered in the display apparatus 200 and a second area 20 to display installable items received from the external network 100. That is, the first area 10 is a destination to which a selected item is added and the second area 20 is a source from which installable items are provided.

0046The user selects an item to install by manipulating a direction key on the user input unit 270 and moving the cursor C on the second area 20. In <figref idref="f0003">FIG. 3A</figref>, the cursor C is placed on a 'weather' widget. If the user selects the 'weather' widget to add it, the UI generator 240 generates a UI showing a process of moving the selected 'weather' widget to the first area 10 as shown in <figref idref="f0004 f0005 f0006">FIGS. 3B to 3D</figref>. That is, the UI generator 240 generates a motion graphic showing that the selected item, i.e., the 'weather' widget, is being moved to the first area 10 along a pre-set path to display the process. It may be an image of the 'weather' widget that is moved to the first area 10.

0047The path along which the selected item is moved is programmed to be pre-set and a plurality of paths may be set.

0048Also, the user may set a moving path until a selected item is installed in the display apparatus 200 and is shown in the first area 10. Setting the moving path will be described in detail hereinafter. The interface 210 receives information of items which can be installed in the display apparatus 200, for example, images or names of the items, from the external network 100 such an internet, and the UI generator 240 generates a UI including an area to display installable items and an area to display items which are already installed in the display apparatus 200.

0049The controller 290 determines a position of the area where the installed items are displayed to install and display a selected item, sets a moving path of the selected item from a position where the item is selected to a position where the selected item is installed and displayed, and moves the selected item along the set moving path and displays the item on the determined position.

0050Also, if the user requests a moving path setting screen to be displayed, the UI generator 240 generates a moving path setting screen showing various moving paths. The option for the moving path includes vertical movement, vertical movement after horizontal movement, oblique movement or curved movement.

0051The moving speed of the selected item, that is, the moving speed of the motion graphic may be set to correspond to the time necessary to add and install the selected item to the first area 10. For example, the UI generator 240 is controlled by the controller 290 to generate a UI in which the speed at which the item selected from the second area 20 is moved and added to the first area 10 is in proportion to the time necessary to install the selected item in the display apparatus 200.

0052If it takes a long time to install the selected item in the first area 10, the controller 290 may control the UI generator 240 to generate a motion graphic having a longer path. That is, the controller 290 may automatically select a moving path as well as the moving speed of the selected item by taking into consideration the time necessary to install the item.

0053The controller 290 may control the UI generator 240 to select a longer path and generate a motion graphic moving along the selected path.

0054The selected item may be displayed by the UI generator 240 in a manner that it is moved to the first area 10 as if it accelerates and drops down to the bottom by the gravity, and may be displayed as a semitransparent or transparent motion graphic. The transparency of the selected item may be controlled by the user through a menu.

0055The selected item is added to the headmost portion of the first area 10, which is a default value, as shown in <figref idref="f0006">FIG. 3D</figref>. The user may change the default value by manipulating the direction key of the user input unit 270, and may change the position of the item added to the first area 10. <figref idref="f0007">FIG. 4</figref> illustrates an example in which the position of the added item is changed. Referring to <figref idref="f0007">FIG. 4</figref>, the added item of <figref idref="f0006">FIG. 3D</figref> is positioned next to the 'restaurant' widget.

0056Also, the user may change and set a default position on the first area in which the selected item is installed using the user input unit 270.

0057The display unit 250 displays the UI input from the UI generator 240, for example, the UI shown in <figref idref="f0003 f0004 f0005 f0006">FIGS. 3A to 3D</figref> and <figref idref="f0007">FIG. 4</figref>, or an image. The display unit 250 may be realized as various display elements such as a liquid crystal display (LCD) panel and a plasma display panel (PDP).

0058The storage unit 260 stores AV signals, moving pictures, installed items, and identification information of the installed items, which are received through the receiver 205 or the interface 210. The identification information of the installed items includes a category and an image of an item. The image of the item may be a thumbnail or an icon.

0059The storage unit 260 stores a program for executing the stored item. For example, if the item is a widget, the storage unit 260 stores a widget application. The UI generator 240 generates a corresponding widget using the widget application. The storage unit 260 may be realized as a hard disk or a non-volatile memory.

0060The user input unit 270, which serves as an interface to receive a command from the user and transmit it to the controller 290, may include a touch panel or various buttons, such as a plurality of number keys, a direction key, and a function key. The user selects an item to install in the display apparatus 200 by manipulating the user input unit 270 and controls a position in which to display the installed item.

0061The remote control receiver 280 receives user manipulation from a remote controller 280a and transmits the user manipulation to the controller 290. The remote controller 280a is operated in a way similar to the user input unit 270.

0062The controller 290 controls entire operation of the display apparatus 200 based on the user command transmitted from the user input unit 270 or the remote controller 280a. Various programs necessary for the control of the display apparatus 200 are stored to the storage unit 260. Also, the controller 290 displays an image according to the user command on the display unit 250. The image according to the user command includes the image described above with reference to <figref idref="f0003 f0004 f0005 f0006">FIGS. 3A to 3D</figref> and <figref idref="f0007">FIG. 4</figref>.

0063If a request to install an item is input from the user input unit 270, the controller 290 controls the UI generator 240 and the display unit 250 to generate and display the UI shown in <figref idref="f0003">FIG. 3A</figref>. If one of installable items displayed on the second area 20 of the UI is selected through the user input unit 270, the controller 290 controls the UI generator 240 to show the process of moving the selected item to the first area 10 with a motion graphic.

0064The controller 290 controls the speed at which the selected item is moved to the first area 10 to correspond to the time necessary to download and install the selected item in the display apparatus 200. Accordingly, the motion graphic of the selected item shows the progress status of the selected item being moved to the first area 10.

0065<figref idref="f0008">FIG. 5</figref> is a flowchart illustrating a displaying method of a display apparatus according to an exemplary embodiment of the present invention.

0066Referring to <figref idref="f0008">FIG. 5</figref>, if a command to install an item is input from the user input unit 270 (S500), the controller 290 controls the interface 210 to receive items which are installable in the display apparatus 200 from the external network 100 (S510).

0067The controller 290 controls the UI generator 240 and the display unit 250 to generate a UI shown in <figref idref="f0003">FIG. 3A</figref> using the installable items received in operation S510 and items stored in the storage unit 260 (S520) and display the UI.

0068If the user selects at least one item from the items on the second area 20 by manipulating the use input unit 270 (S530), the controller 290 downloads a program of the selected item from the external network 100 through the interface 210 and installs the program in the display apparatus (S540).

0069The controller 290 controls the UI generator 240 and the display unit 250 to display the process of moving the selected item from the second area 20 to the first area 10 on the UI (S550). Accordingly, the UI generator 240 generates a motion graphic showing that the selected item is being moved to the first area 10 along a pre-set path as shown in <figref idref="f0004 f0005 f0006">FIGS. 3B to 3D</figref>.

0070The item selected in operation S530 may move to the first area 10 as if it accelerates and drops down to the bottom by the gravity, and also, the moving speed of the selected item may be controlled to correspond to the time necessary to install the selected item in the display apparatus 200.

0071If downloading and installing the item is completed (S560), the UI generator 240 generates a UI in which the selected item is added to a default position of the first area 10 as shown in <figref idref="f0006">FIG. 3D</figref> (S570). The selected item is added to the first area 10 at the same time of completing installation of the item or two operations may be performed with a minute time difference.

0072If the user adjusts the position to display the added item by manipulating the user input unit 270 (S580) and presses an OK button (not shown) of the user input unit 270, the item selected in operation S530 is registered (S590).

0073In the above embodiment, the items are installed and added in the display apparatus 200. However, items may be installed in a web-hard or a web-server. That is, the web-hard or the web-server stores and maintains the items selected by the user. The web-hard or the web-server is provided in another server of the hub-site 120 or the external network 100.

0074If the user requests an item to be additionally installed, the controller 290 controls the interface 210 to receive a list of items already installed in the web-hard or the web-server and a list of installable items through the external network 100. Also, the controller 290 generates a UI as shown in <figref idref="f0003 f0004 f0005 f0006">FIGS. 3A to 3D</figref> using the received lists and shows the process and the moving path in which a selected item is added using a motion graphic as described above.

0075According to the exemplary embodiment of the present invention described above, if an item is selected through a menu, a process and a progress in which the selected item is installed in the display apparatus 200 are shown using the motion graphic of the item. That is, a visual feedback for the movement of the item is reinforced so that a process of adding the item can be intuitively shown to the user. Particularly, the selected item moves along a moving path set on the menu and also moves taking into consideration an installing time, so that the user can easily understand the installing progress of the item.

0076The foregoing exemplary embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the exemplary embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
