Abstract

A method for improving a quality of MPEG-4, or similar, scalable video enchancement layers transmitted over an error-prone network. The method includes the steps of inserting one or more re-synchronisation marker (660, 760, 860) into one or more enchancement layers of a scalable video sequence. When one or more errors (630, 730, 830) is detected in said one or more enhancement layers of said scalable video sequence, data is concealed (640, 740, 840) in the video sequence from a video bit position at which said one or more errors is detected, to a video bit position of a subsequent error free re-synchronisation marker. In this manner, a reduction in the amount of error-free data that has to be discarded can be achieved. This, in turn, reduces the amount of visual degradation in the video transmission.
