摘　　要：提出了利用.NETFramework2.0环境中ADO.NET对象的DataSet处理网络音视频实时播放中的数据缓存,具有操作简单、效率较高的优点。对播放过程中DataSet结构的设计、接收线程和播放线程的设计、音视频数据的同步播放以及线程间数据同步等关键问题做了较为深入地讨论,并给出了具体的实现流程。实际测试结果表明,运行稳定,效果良好。A method is proposed, which utilizes the DataSet of the object of ADO.NET in the environment of .NET Framework 2.0 to deal with the cache of the network audio and video frequencgy data. The mothed has many virtues, such as it can simplify operation, improve efficiency. The design of the DataSet＇ s structure, incept thread and play thread, audio and video data synchronization play, synchronous control methods of thread data in play is discussed, and also the specific process is given. The result of actual test illuminate ran steady and achieved good effect.
