Abstract: A digital device and a control method thereof are disclosed in the present specification. The digital device and the control method thereof according to the present invention may comprise the steps of receiving an image signal; separating the received image signal by a plurality of frequency bands; adjusting a gain for the image signal of each of the separated frequency bands; displaying an enhanced image on a screen by synthesizing the image signals of the respective frequency bands in which the gain has been adjusted; separating the screen, on which the enhanced image is displayed, into a plurality of areas; checking whether the maximum pixel value of the enhanced image displayed on the separated screen area, if the maximum pixel value of the enhanced image is larger than the reference value.

Abstract: In a method for processing a video signal, according to the present invention, a first video decoder can extract motion information for inter prediction on a current half frame from a bitstream, a second video decoder can perform the inter prediction on the current half frame by using the extracted motion information, and the first video decoder can restore the inter-predicted current half frame. Accordingly, the coding time of a video sequence can be reduced.
