| 摘 要： | Linux操作系统下的X—Windows系统仅能实现终端机上的远程图形用户界面，而不能实现声音在终端机上的远程播放，直接限制了X终端的多媒体表达能力。利用虚拟设备机制和远程映射机制，让服务器端用户进程在运行过程中的音频数据映射到服务器端编制的虚拟音频设备上，虚拟音频设备软件截取相关数据后，透过网络发送到对应的X终端，X终端机再利用相关软件映射到本地音频设备进行媒体再现。该模式实现了音频设备的远程映射，使得多媒体播放更加流畅，X终端应用更加广泛。

| Abstract: | The X-windows system of the Linux can only realize remote graphics user interface,but can't realize audio playing,whichdirectly influenced the X terminal's multimedia expressing ability.A scheme of using the virtual device mechanism and mapping mecha-nism was presented,the user process which running on server maps the audio data into the virtual audio device,the virtual audio devicesoftware intercepts the data and send it to the X terminal through network.Finally multimedia to replay was realized by using some sof-tware mapping the native audio device.Remote audio device's map was realized,which can prompt the multimedia playing becomesmoother.X terminal is applied in large scope. |
