MOVING IMAGE DECODING APPARATUS AND PROCESSING METHOD THEREOF

A moving image decoding apparatus for decoding moving image data, where the apparatus includes a receiving unit for receiving moving image data, a decoding processing unit for decoding and controlling a display of decoded data, and an output control unit for outputting image data. The decoding processing unit includes an intra-block line determination unit for selecting a macroblock line in a frame of the moving image data as an intra-macroblock line; a refresh control unit for identifying an area refreshed during one circulation of an intra-macroblock line, wherein the intra-macroblock line is made to periodically circulate in units of a macroblock line for each frame; an error detection unit for detecting a decoding error; an error judgment unit for judging whether the error is within the refreshed area; and a restore point determination unit for determining a restore point to update an image.
