A method for improving a quality of a scalable video sequence communicated over an error-prone network (500). The video sequence includes at least one base layer and at least one enhancement layer comprising a number of inter-coded macroblocks. The method includes the step of replacing (560) at least one inter-coded macroblock with an intra-coded macroblock in one or more enhancement layers of the video sequence. The macroblocks may be replaced periodically or when a PSNR metric exceeds a threshold value. |
