基于UDP协议的视频图像可靠传输的研究和实现

Research and implementation of image reliable transmission based on UDP

由于基于IP的网络中提供的服务并不适合多媒体视频信息的传输;文章针对利用UDP协议进行视频图像传输的优点和不足进行了分析,并根据可靠视频图像传输的要求,在应用层添加了流量控制、确认技术和超时处理机制,从而保证了视频图像传输的有序性和正确性;最后给出了一种在嵌入式LINUX下实现视频图像可靠传输的具体方法和流程。

Since the service of the Internet based on IP is not suitable for the transmission of video information, this paper analyzes the advantage and disadvantage of image transmission based on UDP. According to the requirement of image transmission, flux control and confirm technology and the disposal of overtime are added to the application layer to insure the order and validity of image transmission. Finally, the paper offers a specific method and procedure of image reliable transmission based on embedded LINUX.
