摘要： A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.

摘要： A method for coding a motion vector using a 2-dimensional minimum bitrate predicting technique is disclosed. A mode information (MODE) commonly adopted to the factors ‘X’ and ‘Y’ are transmitted to thereby reduce its transmission burden by using the two-dimensional minimum bitrate predicting technique, so that a coding efficiency of a motion vector can be improved. In addition, the two-dimensional MVD information coding method is proposed for the low transfer rate mobile image which is very small and has very small motion, so that even if a distribution characteristic of the MVD information is changed according to the minimum bitrate prediction, a coding efficiency of a major motion vector can be improved.

摘要： A method for coding a motion vector in a moving picture reduces overall bit rates in a process of moving picture coding includes searching a motion vector prediction candidate for a first block among a plurality of blocks in a macroblock, searching a plurality of motion vector prediction candidates for each of additional blocks in the plurality of blocks in succession upon completion of the search for the plurality of motion vector prediction candidates for the first block. A motion vector median prediction value for the first block is compared to a motion vector bound. If the motion vector median prediction value is determined to lie within a motion vector bound, a predicted value for coding the first block is determined to be the motion vector median prediction value. If it is determined that the motion vector median prediction value does not lie within the motion vector bound, a vector value that lies within the bound of a motion vector prediction candidate among the plurality of motion vector prediction candidate or the motion vector median prediction value is determined to be the predicted value for coding the first block. The steps of comparing a motion vector median prediction value to the motion vector bound and determining a predicted value is repeated for each of the additional blocks in the plurality of blocks in the macroblock.
