Abstract

A method (800) for improving a quality of MPEG-4, or similar, object-based scalable video coding in a video communication system (700) employing one or more enhancement layers and one or more base layers. The method includes the steps of decoding the one or more enhancement layers and one or more base layers of a received scalable video sequence into a plurality of image blocks having one or more predetermined boundaries and identifying at least one object of the decoded enhancement layer as a forward and/or backward shape. The method further includes the step of padding (810) the forward and/or backward shape of the object to one block boundary of the enhancement layer frame.
