    摘要: Provided is a method for partitioning a block in inter prediction including selecting one standard reference frame from at least one reference frame which is a comparison target in inter prediction, searching whether or not a higher-level macroblock of a current frame is partitioned based on the selected standard reference frame, determining a partition size of the higher-level macroblock of the current frame, searching whether or not the higher-level macroblock in which the partition size is determined is partitioned by comparing with any certain reference frame other than the standard reference frame, and stopping a block size search on the higher-level macroblock of the current frame if a partition size of the higher-level macroblock of the current frame determined by comparing with the standard reference frame and a partition size of the higher-level macroblock of the current frame determined by comparing with the certain reference frame are different from each other.

    摘要: An apparatus and a method for performing mixed motion estimation based on a hierarchical search are provided. In the method, motion vectors of previous image data are received. The median value of the motion vectors is obtained. Current image data is received. Motion of the current image data is compensated for based on the median value of the motion vectors. SAD values of the previous image data are received and the maximum value of the SAD values is obtained. The motion compensation result is compared with the maximum value of the SAD values. Motion estimation of the current image data is skipped and the motion compensation result is output if the motion compensation result is smaller than the maximum value of the SAD values. Motion estimation for the current image data is performed if the motion compensation result is greater than or equal to the maximum value of the SAD values, and the motion estimation result is output.

    摘要: The present invention relates to a distributed arithmetic module employing a zero input detection circuit that reduces electric power consumption by avoiding unnecessary calculation. An apparatus for performing a discrete cosine transform (DCT) on a video signal, including; input unit for receiving the video signal in a block by block basis; discrete cosine transform (DCT) unit for receiving each image data block from the input unit and conducting a discrete cosine transform/inverse discrete cosine transform (DCT/IDCT) operation on the received image data block to generate a transformed image data block containing N×M pixel value; zero input detect unit for determining whether pixel values of a current image data block are all “0” and generating a detection signal in order to bypass the DCT/IDCT performing on the current image block; and output unit for outputting the transformed image data block as a transformed video signal.

    摘要: Provided is an apparatus for controlling multiple powers which is capable of turning on and off the multiple powers in their priorities for systems or components to be supplied with the multiple powers such as a liquid crystal display (LCD) module. In the apparatus for controlling multiple powers, an on-signal of high level is applied to an input terminal, and an output of a control signal generating unit is sequentially changed to a high level whenever a clock is applied to a clock signal input terminal by one period, so that outputs of the multiple powers are sequentially output. In addition, an off signal of low level is applied to the input terminal, and an output of the control signal generating unit is changed to a low level in a reversal order whenever a clock is applied to the clock signal input terminal by one period, so that outputs of the multiple powers are interrupted in the reversal order.
