Abstract:
1. A method of encoding an image, the method comprising: determining a storage status of a buffer storing encoded data, for every data unit equal to or less than one macroblock; performing, if a data accumulation rate of the buffer exceeds a predetermined first threshold value based on the determined storage status of the buffer, a reduction mode for reducing data stored in the buffer by rearranging information about a macroblock having a predetermined encoding operation order so that encoded data of the macroblock is reduced; and stopping, if the data accumulation rate of the buffer decreases to a predetermined second threshold value due to the rearranging the information about the macroblock having the predetermined encoding operation order, the reduction mode and performing a predetermined encoding operation by using actual information of the macroblock under the predetermined encoding operation; and storing, in the buffer, data encoded by using data of the image, and the rearranged information about the macroblock.
