The control unit 280 transmits a signal corresponding to a predetermined key operation of the user input unit 230 or a signal corresponding to the movement of the spatial remote controller 201 sensed by the sensor unit 240 to the image display apparatus 100).

5 is a flowchart illustrating an operation method of an image display apparatus according to an embodiment of the present invention.

The control unit 150 or the video / audio processing unit 170 generates icons for multimedia data to be reproduced, and generates an icon list including a plurality of icons (S510). The icon list is generated by arranging a plurality of icons randomly in a three-dimensional graphic. Here, the three-dimensional figure includes a three-dimensional figure expressed on a two-dimensional plane as well as a three-dimensional figure represented by a three-dimensional image. The three-dimensional graphic may include a sphere, a cone, a cylinder, and a polygon. The three-dimensional graphic form is generated by the video / audio processing unit 170.

When the video / audio processing unit 170 generates an image displaying the icon list through the three-dimensional graphic, the display unit 180 displays the generated image (S520). The control unit 150 can control whether the image is generated or not. The above-mentioned icon list having the shape of the three-dimensional figure can be displayed as a three-dimensional image. In this case, the left eye image and the right eye image for displaying the icon list are generated by the video / audio processing unit 170, and then displayed on the display unit 180, thereby performing three-dimensional display.

Also, the three-dimensional figure displayed together with the icon list may be a moving image displayed in a state of rotating or vibrating, rather than a still image. The motion patterns of the three-dimensional graphics can be expressed in various ways, and the rotation is merely an example. In addition, the icons constituting the icon list in the rotating three-dimensional graphic can move irregularly. That is, animations such as random blending of icons within a three-dimensional graphic may be displayed. In this case, the controller 150 generates the three-dimensional graphic image as a moving image to be rotated. Accordingly, the user can visually recognize that the multimedia data is being reproduced according to the "random play" scheme in which the reproduction order is randomly determined.

The controller 150 reproduces the multimedia data in random order, and randomly selects an icon corresponding to the multimedia data to be reproduced or the multimedia data to be reproduced (S530). In the icon list, the icon corresponding to the multimedia data to be reproduced will be referred to as a playback icon hereinafter. The play icon is determined as one of the icon lists made up of the icons corresponding to the multimedia data that have not been played yet and the icon determined by the play icon can be displayed as moving out of the three-dimensional figure.

The control unit 150 may randomly select a play icon from the icon list and then play the corresponding multimedia data. Alternatively, if the controller 150 randomly selects multimedia data and then determines an icon corresponding to the selected multimedia data as a play icon, the video / audio processor 170 constructs an image so that the play icon is displayed outside the three-dimensional figure .

The control unit 150 reproduces the selected multimedia data (S540). The multimedia data may be stored in a storage unit of the image display apparatus or may be stored in an external storage medium detachably connected to the image display apparatus. The external storage medium may be, for example, an external hard disk, a usb memory, a compact disc (CD), a digital video disc (DVD), or the like connected to the image display device through various terminals of the external device input / When the control unit reads the multimedia data from the external storage medium and reproduces the multimedia data, the video and / or audio signals for the multimedia data can be received through the external device input / output unit 130.

The multimedia data may be still image data, moving image data, voice data, or the like. In the embodiment of the present invention, the multimedia data is voice data. When the multimedia data is audio data, the audio output unit 185 of the video display device outputs audio corresponding to the reproduction of the multimedia data.

Then, the control unit 150 generates a playback image corresponding to the playback of the multimedia data and displays the playback image on the display unit 180 (S550). When the reproduction image is displayed, when the reproduction icon moves out of the three-dimensional figure, the reproduction image may appear on the display unit 180 so that the reproduction icon that appears outside the three-dimensional figure appears to be deformed.

When one reproduction icon is selected and the reproduction of the multimedia data corresponding to the reproduction icon is completed, the controller 150 inputs a predetermined command signal for updating the icon list to the video / audio processing unit 170. Accordingly, the video / audio processing unit 170 may modify or reproduce an image that displays the three-dimensional graphic or icon list, so that the icon corresponding to the multimedia data that has been reproduced is deleted. The video / audio processing unit 170 can generate an image in which the deleted icons are displayed from the icon list in the three-dimensional graphic to be displayed in a region separate from the three-dimensional graphic. Accordingly, the display unit 180 displays the deleted icon in the icon list in the three-dimensional graphic on a part of the screen.

The playback image is an image for indicating the playback state or playback state of the multimedia file. Information on one or more of the file name, the total reproduction time, and the current reproduction time of the multimedia data currently being reproduced can be displayed on the reproduction image.

6 to 9 are views showing an example of a screen displayed according to an embodiment of the present invention.

FIG. 6 illustrates a full screen 600 displaying an icon list and a playback image according to an embodiment of the present invention. Referring to FIG. 6, a three-dimensional graphic 700, a reproduced image 800, and a deletion icon list 900 are displayed on the full screen 600 during reproduction of multimedia data.

In the three-dimensional graphic 600, an image is displayed as if the icon list is included as described above, and one of the icons in the icon list is selected as a playback icon. Then, the icon selected by the play icon moves out of the three-dimensional graphic 600 and is displayed as if it is changed to the playback image 800. [ That is, the playback icon is deleted while moving out of the three-dimensional graphic 600, and the playback image 800 is generated and displayed in the same place. Accordingly, the user can intuitively know that the playback image 800 is related to the multimedia data corresponding to the playback icon or the playback icon.

When the reproduction of the multimedia data is completed, the reproduced image 800 disappears and the icon for the corresponding multimedia data is displayed again. The re-displayed icon moves to the delete icon list.

A deletion icon list 900 in which icons deleted from the icon list before reproduction are displayed is displayed. Since the delete icon list 900 is displayed in a region separate from the place where the three-dimensional graphic is displayed, it is displayed to be distinguished from the icon list of the data that has not yet been reproduced. Therefore, in the random play method according to the embodiment of the present invention, once reproduced multimedia data is not selected again, overlapping reproduction can be prevented. Then, the user can grasp what the already-reproduced multimedia data is.

7 is a diagram illustrating an example of an icon list displayed according to an embodiment of the present invention. The icon list is displayed in a three-dimensional graphic. In addition, a three-dimensional figure including an icon list can be displayed as a stereoscopic image. As described above, the three-dimensional graphic may be a rotating stereoscopic video, and the icons in the three-dimensional graphic may be displayed as being irregularly moving. In the icon list according to the embodiment of the present invention, the icons may be irregularly arranged rather than being arranged or stopped constantly, or the random play may be visually highlighted by irregular movement. In addition, the name of the multimedia data corresponding to the corresponding icon or the type of the file may be displayed in each icon.

In FIG. 7, although the three-dimensional figure is illustrated as being cylindrical, the three-dimensional figure may have various shapes as long as it is a shape that can be expressed in three dimensions such as a sphere, a cone, and a polygon.

FIG. 8 shows an example of a reproduced image 800 displayed according to an embodiment of the present invention. For example, the file name 810 of the multimedia data, the current playback time 820 indicating the amount of playback of the multimedia data, the total number of multimedia files And a total reproduction time 830 indicating the amount of reproduction may be displayed. And a figure 840 that visually shows the ratio of the current playback time to the total playback time. In addition, a thumbnail image generated for the multimedia data may be displayed together with the playback image 800.

Also, a button-shaped image such as a playback button, a stop button, a pause button, or a repeated playback button may be further displayed in the playback image. In this case, when a user signal is input from the remote control device 200 such as a space remote controller at a position where the buttons are displayed, the remote control device interface 140 transmits a user signal to the controller 150 ).

When the reproduction of the multimedia data is completed, the reproduced image 800 is deleted. In addition, an icon may be displayed again at a position where the playback image 800 is deleted. In this case, the displayed icon is a delete icon 910 to be described with reference to FIG. 9 is a diagram illustrating deleted icons displayed according to an embodiment of the present invention. In Fig. 9, a deletion icon 910 and a deletion icon list 900 are displayed. The deletion icon 910 may be displayed as moving into the delete icon list 900 at the position where the playback image was located. The deletion icon 900 may further display the file name of the corresponding multimedia data. Accordingly, the user can easily recognize which multimedia data has been reproduced through the delete icon list 900. [
