Abstract: 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.

Abstract: A video data coding/decoding apparatus includes: an encoder dividing a partition partitioned by a data partitioning technique into certain blocks, channel-coding the divided block data and transmitting a bit stream; and a decoder channel-decoding the bit stream received from the encoder so as to restore a video data. An error occurrence probability can be reduced by channel decoding the source-coded video data for each partition. In addition, by removing the marker emulation generated in the channel coding, a mobile image data of a better picture quality can be provided.
