Apparatus and method for controlling screen layout in digital broadcast receiver for receiving moving picture content

1. An apparatus for controlling a screen layout in a digital broadcast receiver, the apparatus comprising:

a data reception conversion unit for receiving head-end side data including configuration data of lattice-type moving picture contents sent via a broadcasting network and then converting the received head-end side data into content picture configuration data; and

a content picture configuration unit for arranging multiple moving picture contents through a curved-type circular selection picture on a display means of a user terminal by using the content picture configuration data, for editing the multiple moving picture contents so as to display a focus moving picture content selected by a user in an enlarged size larger than other moving picture contents, and for arranging the moving picture contents along a curve of the curved-type circular selection picture in such a manner that partial regions of the multiple moving picture contents overlap each other, wherein the focus moving picture content has a largest size, and the farther each moving picture content from the focus moving picture content is, the smaller each moving picture content becomes,

wherein the content picture configuration unit comprises a search picture setting unit for generating a screen layout control signal from the content picture configuration data and user's content selection data input to a key input reception unit, and then providing the generated screen layout control signal to an output video editing unit, and

wherein the graphic editing unit edits a picture graphic by using the screen layout control signal, so as to display a graphic display picture other than multiple moving picture contents to be displayed on the display means of the user terminal and additional information about the focus moving picture contents selected by the user in a region excluding the multiple moving picture contents.

2. The apparatus as claimed in claim 1 , wherein the content picture configuration unit further comprises a video/graphic merging unit for merging a picture graphic output from the graphic editing unit with multiple moving picture contents output from the output video editing unit, thereby generating a picture to be displayed.

3. The apparatus as claimed in claim 1 , which further comprises an audio configuration unit for receiving audio configuration data from the data reception conversion unit, and then outputting audio data matching with a moving picture content selected by a user among the received audio configuration data.

4. The apparatus as claimed in claim 1 , wherein the head-end side data comprises a media source delivered to the content picture configuration unit so as to define a display type of the display means of the user terminal.

5. The apparatus as claimed in claim 1 , wherein a display switching of the focus content is performed in any display switching mode selected from among normal, fade-in, fade-out, cross-fade, wipe, page-effect, split, and zoom modes.

6. A method for controlling a screen layout in a digital broadcast receiver, the method comprising the steps of:

receiving head-end side data including configuration data of lattice-type moving picture contents sent via a broadcasting network, and converting the received head-end side data into content picture configuration data;

editing the content picture configuration data and configuring a curved-type circular selection picture so as to display the edited content picture configuration data through the curved-type circular selection picture on a display means of a user terminal, the editing of the content picture configuration data and the configuring of the circular selection picture including:

generating a screen layout control signal from the content picture configuration data and user's content selection data input to a key input reception unit, and

providing the generated screen layout control signal to an output video editing unit and a graphic editing unit;

editing a picture graphic by using the screen layout control signal so that a graphic display picture other than multiple moving picture contents to be displayed on the display means of the user terminal and additional information about the focus content is displayed in a region other than a region displaying the multiple moving picture contents;

displaying the configured curved-type circular selection picture containing the moving picture contents on the display means of the user terminal;

arranging multiple moving picture contents through a circular selection picture on the display means of the user terminal by using the screen layout control signal; and

editing the moving picture contents so that a focus content selected by a user can be displayed in an enlarged size larger than other moving picture contents,

wherein the moving picture contents are arranged in such a manner that the focus content has a largest size, and the farther each moving picture content from the focus content is, the smaller each moving picture content becomes,

wherein the moving picture contents are arranged along a curve of the curved-type circular selection picture in such a manner that partial regions of the multiple moving picture contents overlap each other.

7. The method as claimed in claim 6 , further comprising a step of merging a picture graphic output in the step of editing a picture graphic by using screen layout control signal with multiple moving picture contents output in the step of arranging multiple moving picture contents, thereby generating a picture to be displayed on the display means of the user terminal.

8. The method as claimed in claim 6 , further comprising the steps of:

receiving audio configuration data together with the head-end side data; and

outputting audio data matching with a moving picture content selected by a user among the received audio configuration data.

9. The method as claimed in claim 6 , wherein the head-end side data comprises a media source for defining a display type of the display means of the user terminal.

10. The method as claimed in claim 6 , wherein a display switching of the focus content is performed in any display switching mode selected from among normal, fade-in, fade-out, cross-fade, wipe, page-effect, split, and zoom modes.
