Abstract

A video display device provides multispeed video search, and a control method thereof. The device includes a video display unit to display a video, and a sensor unit to detect user input and transmit an input signal based on the detected user input to a processor that provides a video search interface. The video search interface includes an image display interface, a thumbnail search interface displaying thumbnails of a video, and a thumbnail control interface controlling the image display interface and/or the thumbnail search interface. The thumbnail control interface includes a circular controller, and controls display of an image on the image display interface based on rotation of the circular controller.

9. The video display device according to claim 8, wherein the image of the thumbnail includes at least one frame image of a plurality of frame images corresponding to the thumbnail.

10. The video display device according to claim 1, wherein the processor is configured to rotate the circular controller in response to the first input signal, and display, on the image display interface, an image of the thumbnail of the plurality of thumbnails displayed on the thumbnail search interface corresponding to the position of the rotated circular controller in response to rotation of the circular controller.

11. The video display device according to claim 1, wherein the processor is configured to rotate the circular controller in response to the first input signal, and move at least one of the plurality of thumbnails displayed on the thumbnail search interface and the thumbnail control interface in response to rotation of the circular controller.

12. The video display device according to claim 1, wherein the processor is further configured to control an image displayed on the image display interface based on the position of the circular controller.

13. The video display device according to claim 1, wherein the processor is configured to control a positional relationship between the thumbnail search interface and the thumbnail control interface in response to a second input signal.

14. The video display device according to claim 1, wherein the thumbnail control interface displays a plurality of thumbnails with respect to a plurality of frames corresponding to a time interval between a thumbnail of the plurality of thumbnails displayed on the thumbnail search interface corresponding to a position of the thumbnail control interface and a next thumbnail.

15. The video display device according to claim 14, wherein the processor is configured to display, on the image display interface, an image of one thumbnail of the plurality of thumbnails displayed on the thumbnail control interface in response to a third input signal.
