The controller 280 transmits a signal corresponding to a predetermined key manipulation 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 through the wireless communication unit 220. 100).

5 is a flowchart illustrating a method of operating an image display apparatus according to an exemplary embodiment.

The controller 150 or the video / audio processor 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 in a form in which a plurality of icons are randomly arranged in a 3D figure. Here, the three-dimensional figure includes a three-dimensional figure represented by a three-dimensional image as well as a three-dimensional figure represented on a two-dimensional plane. Three-dimensional figures may include spheres, cones, cylinders, polygons, and the like. The 3D graphic is generated by the image / audio processor 170.

When the image / audio processor 170 generates an image on which an icon list is displayed through the 3D graphic, the display 180 displays the generated image (S520). The controller 150 may control whether to generate or display an image. The above-described icon list having a shape of a 3D graphic may be displayed as a 3D image. In this case, the left eye image and the right eye image for displaying the icon list are generated by the image / audio processor 170, and then displayed on the display unit 180 to perform 3D display.

Also, the 3D figure displayed together with the icon list may be a moving image displayed in a rotating or vibrating state, not a still image. The motion method of the three-dimensional figure may be expressed in various ways, and the rotation is only one example. In addition, icons constituting the icon list may move irregularly in the rotating three-dimensional figure. That is, an animation may be displayed such that icons are randomly mixed in the 3D figure. In this case, the controller 150 generates the 3D figure as a moving picture. Therefore, the user can visually recognize that 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 a 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, an icon corresponding to the multimedia data to be played is referred to as a play icon hereinafter. The play icon is determined as one of an icon list consisting of icons corresponding to multimedia data not yet played, and the icon determined as the play icon may be displayed as moving out of the 3D figure.

The controller 150 may randomly select a play icon from the icon list and play the multimedia data corresponding thereto. Alternatively, when the controller 150 randomly selects the multimedia data and then determines an icon corresponding to the selected multimedia data as the play icon, the image / audio processor 170 may compose the image so that the play icon is displayed out of the 3D figure. Can be.

The controller 150 plays the selected multimedia data (S540). The multimedia data may be stored in a storage unit of the image display apparatus or 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, a digital video disc, or the like connected to an image display device through various terminals of the external device input / output unit 130. When the controller reads the multimedia data from the external storage medium and plays the multimedia data, the video signal and / or audio signal for the multimedia data may be transmitted through the external device input / output unit 130.

The multimedia data may be still image data, video data, audio data, or the like. In the embodiment of the present invention, a case where the multimedia data is voice data will be described. When the multimedia data is audio data, the sound output unit 185 of the image display device outputs sound according to reproduction of the multimedia data.

The controller 150 generates a reproduced image according to the reproduction of the multimedia data and displays it on the display unit 180 (S550). Here, when the playback image is displayed, when the playback icon moves out of the 3D figure, the playback image may appear on the display unit 180 so that the playback icon out of the 3D figure appears to be deformed.

When one play icon is selected and playback of multimedia data corresponding to the play icon is completed, the controller 150 inputs a predetermined command signal for updating the icon list to the video / audio processor 170. Accordingly, the image / audio processor 170 may modify or reproduce the image displaying the 3D figure or the icon list so that the icon corresponding to the multimedia data that has been played back may be deleted. The image / audio processor 170 may generate an image in which the deleted icons are displayed from the icon list in the 3D figure to be displayed in a region separate from the 3D figure. Accordingly, the display unit 180 displays an icon deleted from the icon list in the 3D figure in a partial area of the screen.

The playback video is a video for showing the playback status or playback status of the multimedia file. The playback image may display one or more information of a file name, a total playback time, and a current playback time of multimedia data currently being played.

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

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

In the three-dimensional figure 600, an image is displayed as if the icon list is included as described above. One of the icons in the icon list is selected as the playback icon. Then, the icon selected as the playback icon is displayed as if it is moved out of the three-dimensional figure 600 and replaced with the playback image 800. That is, the playback icon is deleted while moving out of the 3D graphic 600, and the playback image 800 is generated and displayed at the same position. Accordingly, the user may intuitively know that the corresponding playback image 800 is for a playback icon or multimedia data corresponding to the playback icon.

When playback of the multimedia data is completed, the playback image 800 disappears and an icon for the corresponding multimedia data is displayed again. The displayed icon is then moved to the delete icon list.

A delete icon list 900 is displayed in which icons deleted from the icon list before playback are collected. Since the delete icon list 900 is displayed in a separate area from where the 3D figure is displayed, the delete icon list 900 is displayed separately from the icon list of data which has not been reproduced yet. Therefore, in the random play method according to the embodiment of the present invention, since the multimedia data reproduced once is not selected again, redundant reproduction can be prevented. And the user can grasp what multimedia data is already played.

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 within the three-dimensional figure. In addition, the three-dimensional figure including the icon list may be displayed as a stereoscopic image.

The total reproduction time 830 and the like indicating the quantity may be displayed. The figure 840 visually showing the ratio of the current playback time to the total playback time may be displayed together. In addition, a thumbnail image generated with respect to the multimedia data may be included and displayed together with the playback image 800.

In addition, a button-shaped image such as a play button, a stop button, a pause button, a repeat play button, and the like may be further included and displayed in the play image. In this case, when a user signal is input from the remote controller 200 such as a spatial remote controller at the position where the above-described button is displayed, the remote controller interface unit 140 controls the user signal to perform an operation corresponding to the corresponding button. ).

When playback of the multimedia data is completed, the playback image 800 is deleted. The icon may be displayed again at the position where the reproduced image 800 is deleted. In this case, the displayed icon is a delete icon 910 to be described with reference to FIG. 9. 9 illustrates deleted icons displayed according to an embodiment of the present invention. 9, a delete icon 910 and a delete icon list 900 are displayed.
