摘　　要：研制了一种新颖的应用于网络遥操作机器人系统的网络视频流传输系统,该系统基于C/S模型并采用MPEG4视频编码器对图像进行编解码,实现了机器人现场视频的实时采集、编码、传输和播放。此外,对网络遥操作机器人系统的视频、音频和力信息的传输同步问题展开了研究。实验证明所研制的系统不仅能保证机器人现场图像传输的实时性,而且能较好地实现多信息的同步。A novel video stream delivery system applied to the telerobot system via network is developed. Based on C/S module, the MPEG-4 software CODEC is adopted in the system to compress and decompress the digital video data. It can realize the real-time capture, coding, transmission and play of the telerobot＇ s video. Furthermore,the problem of the transfer synchronization of video, audio and force information in the telerobot system is also investigated. Experimental results show that this system can not only guarantee the transmission with a very short delay but also realize the synchronization of multi-information preferably.
