Abstract
In a video streaming system, the VCR operations such as fast forward, fast backward etc, need more network bandwidth than the normal playback due to the transmitting of redundant frames. In this paper, a novel scene-detection scheme was proposed, and introduced to the implement method of fast forward operation. The scheme allocates bandwidth according to each scene’s length, and select frames in each scene to be displayed dynamically. Experimental results show that the scheme can implement the fast forward operation at a bandwidth which was allocated for the normal playback situation, meanwhile keep the frame rate in the range of 22 to 27 and the mean average activity greater than 95 percent until the speed factor 24.
