Design And Application Of The Embedded Video Communication And Monitor System That Used In Visual Talk-Back Of The Intelligent Building

With the development of the information times and the popularization of intelligent building, the visual talk-back system becomes an important symbol to modernized building.Make a comprehensive view of the domestic industry, the visual talk-back system almost adopts simulate video technology to transmit video signal, this traditional manner has a good many abuse. While using digital video technology ,embedded technology and network technology can work out the problems caused by the traditional manner. At the same time, add the monitor function to the visual talk-back system is one of the develop orientations .This paper realizes a digital embedded video communication and monitor system that used in visual talk-back. The whole system is realized on embedded software and hardware, the sender and receiving end use the exploit board which based on S3C2410 processor and combined with the embedded Linux operating system-armlinux to carry out.The main contents is as follows:Firstly, by analyzing the condition of the traditional visual talk-back system, pointing out its abuse and the current of the digitizing development, bring forward a scheme to combine visual talk-back with monitor, which use the monitor as a branch function module, and the monitor goes round independently.Secondly, expound the compose structure and exploitation process of the...
