UDP协议在视频图像传输中的扩展与应用

Expansion＆Application of UDP Protocol in Video Image ransmission

根据UDP协议的特点，结合视频网络传输的要求对其进行扩展，给UDP数据包定义了一个8个字节的包头结构，用来加载数据包的序列号、时戳等信息。在发送端对传榆进行平滑处理，控制数据包大小和时戳间隔，减小了图像抖动的发生。应用给出了一种在Delphi下实现的视频数据打包流程，能够满足多种网络平台上的视频传输的要求。

Under the UDP protocol characteristics,the combination of video network transmission requiiements be extended to define a UDP packet 8 bytes of header structure,used to load the packet sequence number, timestamp and other information.In the transmitter to smooth the transmission,control,packet size and timestamp interval,reducing the occurrence of image jitter.We give a Delphi application to achieve the video data packing process,to meet a variety of network platforms for video transmission.
