Abstract: PURPOSE: A method for predictive intra coding/decoding for video and an apparatus for same are provided to improve estimation performance by performing intra estimation by sub-unit for the intra-estimation of a coding unit. CONSTITUTION: An intra-prediction video coding apparatus includes an intra predictor(110), a subtractor(120), a storage(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 for a coding unit to the intra predictor. The intra predictor individually predicts a plurality of sub-units included in the coding unit in the IPM. Specifically, the intra predictor sequentially predicts the sub-units of a coding unit, referring to stored intra-prediction coded pixels in the intra-prediction order. The intra predictor also generates a predicted sub-unit 10 by applying the IPM to each sub-unit. In the process of intra-prediction, a recovered sub-unit(30) is created from residual data between a predicted sub-unit(10) and an original sub-unit(20) at the same position as the predicted sub-unit and the intra predictor uses the pixels of the recovered sub-unit as a reference for intra-prediction of a next sub-unit. Upon completion of intra-prediction for every sub-unit of the coding unit, the intra predictor calculates the cost of the IPM for the coding unit.

Abstract: A block mode determining method for video encoding, and an apparatus therefor are provided to determine various macro block modes in an early stage according to a degree of block size activity by using the history characteristic of block size for a prior macroblock, thereby reducing the amount of motion estimation and rate-distortion operation required to a macroblock mode selection process significantly to reduce the entire complexity of an encoding system greatly. A macroblock mode determiner(210) comprises a block determiner(220), a substitute mode estimator(230), and a block mode selector(240). The block determiner compares a predetermined LBHM(Large Block History Map) value with a predetermined threshold value to determine a degree of the block size activity of an inputted macroblock. The substitute mode estimator selects only a part of block modes which the macroblock can have according to the degree of the block size activity. The block mode selector calculates motion estimation and rate-distortion values for available substitute modes selected from the substitute mode estimator to determine the optimal macroblock mode.
