The controller 50 executes the screen saver using the selected image (step 720).

That is, when any one specific image is selected, the controller 50 executes the screen saver by changing the size or display position of the selected image. In addition, when a plurality of images is selected, the controller 50 sequentially displays the selected plurality of images and executes a screen saver.

15 is a flowchart for explaining a screen saver execution method step by step according to a sixth embodiment of the present invention.

Referring to FIG. 15, the controller 50 allows the first content selected by the user to be received, and accordingly controls the reproduction of the received first content (step 800).

The controller 50 determines whether the first content being played satisfies a screen saver operation condition (step 810).

In this case, since the process of playing the first content or the process of determining whether the screen saver operation condition is satisfied has been described above, a description thereof will be omitted.

If the first content satisfies the screen saver operation condition, the controller 50 cuts off the power supplied to the display unit 44 to change the screen to the off state (step 820). In this case, the controller 50 turns off only the screen so that the audio signal included in the first content is normally output.

When the reproduction of the first content being played is terminated, the controller 50 causes the second content to be played next to the first content to be received, and accordingly, controls the second content to be played (step 840).

In this case, the controller 50 determines whether the second content also satisfies the screen saver operation condition as in the first content (step 850).

If the second content also satisfies the screen saver operation condition, the controller 50 continuously cuts power supplied to the display unit 44 to maintain the off state of the screen (step 860).

In addition, if the second content is not satisfied with the screen saver operation condition, the controller 50 supplies power to the display unit 44 to change the screen to an on state, and accordingly, the second content is transmitted through the screen. In operation 870, the video signal corresponding to the control is displayed.

According to an embodiment of the present invention, when a music content or a still image content having no image is played, a screen saver is provided in association with the provided content, thereby providing an adaptively changing screen saver to improve user satisfaction. And, by selectively turning off the screen, unnecessary power consumption can be reduced.

Although the display device for providing the screen saver providing apparatus and method according to an embodiment of the present invention has been described above, the system for providing a method for providing a screen saver including the essential contents of the present invention, and a program including the system are provided. The present invention can also be applied to a computer-readable recording medium executed in the present invention.

In addition, although embodiments of the present invention have been described, the scope of the present invention is not limited by these embodiments, and the scope of the present invention is defined by the interpretation of the claims. Various modifications are possible to the above-described embodiments, and these modifications are all included in the scope of the present invention.
