中文摘要：

提出了一种调节视频分块在时间轴上分布集中的视频块调度算法,满足了用户能快速接收时间轴上随机分布、内容上连续且数量较多的视频段的需求,从而使用户在短时间内了解初始视频的有效内容.该算法可有效引导视频块的传输,大大降低递交延时.实验结果表明,视频分块调度算法有效可行.

英文摘要：

An algorithm of randomly intensive dissemination of video fragments in opportunistic network was proposed to satisfy the requirement of more number of video segments distributed randomly in time axis and sequenced in content so that users can acquire effective information of the original video. The proposed algorithm can guide transportation of video blocks while delivery delay is reduced sharply. Simulations show that random-sequential content spreading（ RSCS） significantly outperforms these approaches in terms of random-sequential index. Moreover,RSCS also achieves better performance levels in ratio of delivery and latency than sequential solution.
