Abstract
A method for processing saturated video intervals in a video sequence. The method either removes or retains the saturated interval. If the interval is removed, the sequence is altered to accommodate the removal. The accommodation is either complete elimination, substitution of a derived interval, or substitution by repeating adjacent intervals. If the interval is retained, information is extracted while limiting the effects of the saturation. The interval can either be encoded with lower data rates, with increased data rates being applied to subsequent intervals, the temporal prediction encoding can be forced to a B interval, an I interval can be inserted, or the sequence restarted, or a coupled encoder decoder system can be set up that uses the same transform and clipping steps to limit the effects of saturation.
