本文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，实验证明该系统不仅图像传输质量高，而且能保证机器人现场图像传输的实时性。关键词：C/S 模型；MPEG-4；视频传输；遥操作机器人Abstract：This paper develops a novel video stream delivery system which is applied in thetelerobot system via network. This system is based on C/S module and adopts MPEG-4 software CODEC to compress and decompress digital video data. It implements the telerobot’s video real-time capture, coding, transmission and play. Experimental results show that this delivery system not only obtains good perceptual picture but also guarantees the transmission has a very short delay.Key words：C/S Module；MPEG-4；video transmission；robot teleoperation
