摘要
数字视频监控产品具有巨大的潜在市场和可观的经济效益,目前我国有数百家公司及科研机构参与该产品的开发和销售。笔者研究的对象是多功能网络摄像系统,其特点是控制摄像头的视频接收端,摄像头上的微型电机带动摄像头的镜头前后移动,通过发送的控制信号控制电机运动,从而达到调整焦距的目的。它可以应用于远程监控及视频会议等。同时论述了视频图像网络传输以及其具体的网络传输过程。
Digital video surveillance products have a huge potential market and considerable economic benefits.Till now,hundreds of companies and research institutions have participated in the developing and marketing of such kind of products in our country.This study focused on the multi-functional network camera system.Its main feature function is realized by the receiving port of controlling camera.There is a micro electromotor on the camera to control the camera lens＇ movement.,and the movement of electromotor is controlled by sending signal,thus achieving the purpose of adjusting focal length.This system can be used for distant control,videoconferencing and so on.In this paper the network transmission of video image and the specific processes of network transmission are discussed.
