Abstract: A motion search apparatus and a motion search method are provided to decrease the number of cycles for predicting all motion vectors and improve the accuracy in prediction of the motion vectors. A search line-setting unit(310) determines the position of a macro block if one block is inputted, and then sets the length of a horizontal search line according to surrounding motion vectors and a predetermined parameter. A motion-predicting unit(320) calculates a predictive motion vector by a midpoint of the surrounding motion vectors to select a start point of the horizontal search line. A searching unit(330) sets a vertical direction value of the predictive motion vector as an initial search line, and calculates SAD(Sum of Absolute Differences) by searching at least one horizontal search line sequentially. A motion-selecting unit(340) determines a position of the minimum SAD on the horizontal search line to select the determined position as a final motion vector.

Abstract: PURPOSE: A method for coding/decoding an intra prediction mode of video and an apparatus for the same are provided to encode/decode IPM information based on a relationship between a current block and neighboring blocks, to thereby effectively increase compression rate. CONSTITUTION: An intra-prediction video coding apparatus includes an intra predictor(110), a subtractor(125), a memory(130), a residual data encoder(140), a residual data decoder(150), an adder(155), an entropy encoder(160), a controller(180), and a MUX(Multiplexer)(190). The controller indicates an IPM to the intra predictor. The intra predictor predicts a CS according to the IPM, referring to previously predicted pixels stored in the memory, for example, neighboring pixels above or to the left of the CS and calculates the cost of the IPM for the CS. In this manner, the intra predictor performs intra prediction on the CS in the IPMs and calculates the costs of the respective IPMs. Then the intra predictor selects an IPM with a minimum cost for the CS. While the controller notifies the intra predictor of IPMs one by one in an embodiment of the present invention, to which the present invention is not limited, it can be further contemplated that upon receipt of a command indicating intra-prediction for a sub-unit from the controller, the intra predictor predicts the sub-unit sequentially in the IPMs.
