Sprite coding

(57) The candidate for summary sprite regulation is completely specified as one "sprite" according to one or more "orbits" through video arrangement at the time of these first appearances. The above-mentioned sprite is an implication about all the picture features of the object which lets the above-mentioned video arrangement pass. One or more orbits bend or change the above-mentioned sprite, and express the above-mentioned object in each frame of the above-mentioned video arrangement. The one or more above-mentioned candidates for sprite regulation are the subsets for in the above-mentioned common video arrangement general, and when these appear first in video arrangement, they have the information in which many use is possible for general. The simplified compression method (1100) enables it to use the information on the addition which can be used about the above-mentioned candidate for sprite regulation more efficiently than the above-mentioned additional information by the coding and decoding processing (64 and 700) about a general object. As a result, the processing for by this simplification processing (1100) / of the above-mentioned common video arrangement / one or more sprite regulation improves further the bit rate conditions and efficiency about storing and transmission of the above-mentioned general video information.
