Abstract: The key of applying streaming media is the management of resources. Among many dynamic management methods for streaming media, Selective PeriodPatching method has distinct advantages and certain shortcomings at the same time. Based on Selective PeriodPatching method, the dynamic self-adapting incorporative method for streaming media was brought forward, which would improve the efficiency of the resource utility and the serving capacity of the system.

Key words: streaming media, multicast stream, self-adapting incorporative method

摘要： 流式媒体应用的核心问题是资源调度,在诸多媒体流的动态调度算法中,SelectivePeriodPatching算法有显著优点,但仍有不足。文章在SelectivePeriodPatching算法基础上,提出媒体流动态自适应合并策略,可有效利用系统资源,提高系统服务性能。
