Abstract
In order to stop the error propagation and the quick of degradation of the reconstructed video quality, the traditional method is intra-frame refresh. This paper proposes a novel error-resilient method which names predictive picture refresh based on scene-context reference picture. And it also proposes a novel shot cut detection to achieve the scene-context reference picture, instead of the traditional video segmentations, such as pixel or histogram difference methods. And our shot cut detection needs less computation and is easily embedded in the H.264/AVC. When the unreliable wireless network requires high intra-frame-refresh rates, compared with the intra-frame-refresh method, our method can achieve apparent saving effect in frame bits while maintaining the similar quality
