摘　　要：流媒体技术应用越来越广泛,但数据传输中的延迟、抖动,影响了媒体流播放质量。如何提供保证性能的流媒体服务成为推广流媒体技术的关键。提出了最小延迟算法,可以提供高的信道利用率及高的目的端缓冲区数据吞吐量,提高媒体流播放质量。还提出了最小聚类延迟算法作为改进,进一步优化媒体流整体播放性能。上述两种算法在流媒体技术中有一定的应用推广价值。Although streaming media technology is widely used, its multimedia stream playback quality is low because of data transmission delay and jitter. High quality of streaming media service is the key to extend the range of streaming media application. In this paper, an algorithm, minimal delay algorithm is presented. This algorithm can provide high channel utility rate, high destination buffer throughput and high playback quality of multimedia stream. Minimal cluster delay algorithm is described as an improvement to optimize the integrated system performance. These two algorithms can be used in streaming media technology.
