Abstract
Provided are methods and apparatuses for coding a motion vector by a multimedia image codec. The method including: calculating and storing difference vectors which represent differences between adjacent motion vectors of image data; selecting a central axis of the stored difference vectors based on trend information of the difference vectors; transforming the difference vectors based on the central axis of the difference vectors; and performing bit coding using the axis-transformed difference vectors.
