基于细粒度调整的同步播放控制算法

针对网络时延和时延抖动引起缓存波动而造成的流媒体播放不连续,基于接收端播放速率调整,提出一种播放速率自适应调整的播放缓存控制算法。算法依据缓存区的占用水平,通过构造控制序列,动态、细粒度地调整媒体的播放速率。在校园网环境下的模拟结果表明,该算法能够有效地减少缓存上溢或下溢引起的播放跳跃或停顿,从而实现流媒体的平滑播放。

An Intra-Media Synchronization Control Algorithm Based on Fine Granularity Adjustment of Streaming Media Playback Rates

Focus on the discontinuity of streaming media play-out which caused by network delay and delay jitter,an improved play-out control algorithm is proposed in order to keep streaming media play-out smoothly,which based on the adjustment of receiver play-out speed.In the algorithm,a fine granularity adjustment of streaming media playback rates according to the occupied buffer level and the use of play-out speed control sequence is adopted to eliminate the intention of buffer underflow or overflow.Simulation res...
