流媒体访问技术的探索与实践

The Exploration and Implementation of Streaming Media Access Technology

如今,网络资源尤其是视频在教学中已经广泛应用,但常常出现一些影响教学的因素。本文采用一种基于实时协议的多媒体数据流并发服务控制模型,介绍了数据并发传送的调度控制,由实时协议的反馈机制动态调整控制参数,达到平滑时延的目的。最后通过对时延参数的测试,说明这一数据流控制方式的合理性,同时该方法也适用于网络视频的多点实时传输、网络多点实时监控,有较高的应用价值。

Now,network resources and video in particular have been widely utilized in teaching, but some factors often appear influencing teaching in its progress,the article adopted a sort of multimedia dataflow concurrent service control models based on real-time protocol,introduced the scheduling control of concurrent data transmission,adjusting control parameters dynamically through the feedback system of real-time protocol,achieving the target of smooth delay.Eventually through the test to delay parameter, the rationality of such dataflow control method has been illustrated,meanwhile the method also adapts to multipoint real-time transmission of network video,multipoint real-time network monitoring,containing high application value.
