Mobile wireless video delivery is still challenging due to its limited bandwidth and dynamic channel status. In this paper, a novel approach named dubbing video slides (DVS) is proposed to cope with the bandwidth limitation problem. Based on a statistical video content importance analysis, DVS method can dynamically select and transmit representative video frames which are relatively more important, and discard others according to current network status feedback. To save bandwidth, we can use these representative frames as substitutes for those adjacent video intervals and synchronize with the original audio track during playback. The visual simulation shows DVS works well for video summary in mobile network delivery.
