Abstract
A method and apparatus for generating a bounding rectangle of a VOP for interlaced scan type video signals, which are capable of accurately generating a bounding rectangle, thereby preventing a color bleeding from occurring in the field-based chrominance shape subsampling. The method includes bounding rectangle formation step of forming a bounding rectangle of a video object plane in such a fashion that the bounding rectangle contains an object therein, based on input luminance shape information, optimum setting determination step of determining whether or not a spatial reference point of the bounding rectangle is positioned on an x-y coordinate of coordinate value (2m, 4n) (m and n=0, 1, 2, 3, 4, . . . ), and bounding rectangle adjustment step of varying the bounding rectangle, when it is determined at the optimum setting determination step that the spatial reference point of the bounding rectangle is not positioned on the x-y coordinate of coordinate value (2m, 4n), in such a fashion that the spatial reference point of the bounding rectangle is positioned on an x-y coordinate of coordinate value (2m, 4n).
