Abstract
A method, for an use at an macroblock-based object oriented coding of image sequence having a stationary background comprising the steps of: dividing a background region and an object region from an inputted video; determining an coding techniques, for an individual macroblock belonging to each divided region, as a macro block-based object-oriented coding of image sequence having a stationary back ground or a discrete cosine transformation object-oriented coding of image sequence having a moving object region; coding the method information, by which each macroblock is coded, on condition that the total area of each region is identical to the area of the screen; and storing or transmitting the coded data.
