Design And Development Of Non-linear Retrieval Of Digital Hard Disk Recording System

As for the monitoring system,digital hard disk video is a major component.In this essay,a digital hard disk video system with the function of non-linear retrieval is designed and implemented basically with a view to the requirement of expressway monitoring and the general application.First of all,non-linear retrieval technique is introduced to put forward the system function model,in the light of characteristics of expressway monitoring .moreover ,the proper index file structure is designed to make it more suitable for computer to deal with .Finally ,the net protocol is defined to realized the non-linear retrueval of remote video files.Good reults have been obtained during the process of testing .
