千兆以太网络摄像机的设计与实现

Design and Realization of Gigabit Ethernet Camera

提出了一种千兆以太网络摄像机的设计,摄像机前端采用SONY CCD ICX285及时序发生器CXD1607和视频ADC AD9945,数字图像处理及千兆以太网接口技术的实现采用TIDSP DM648。时序发生器CXD1607产生时序驱动脉冲,ICX285输出原始的模拟视频信号,模拟视频信号经过视频ADC AD9945处理后,将数字视频信号输出到TI DSP DM648,DM648将接收到的数字视频信号经过处理后通过千兆以太网接口传输给上位机。传输协议采用TCP/IP协议,同时在摄像机上集成了HTTP服务和TELNET服务。

A Gigabit Ethernet camera design is proposed, with the front-end of which applies SONY CCD ICX285, timing generator CXD1607 and video ADC AD9945; and the realization of digital image processing and Gigabit Ethernet interface is achieved by using TI DSP DM648. Timing generator generates timing-driven pulse, and the ICX285 outputs the original analog video signals which will be processed by ADC AD9945. Then the processed digital video signals are output to DM648 for processing and then will be transmitted to the host computer by Gigabit Ethernet interface. Transport protocol applies TCP/IP protocol, while both HTTP and TELNET services are integrated on the camera.
