The Research And Application Of Multi-image Processor Based On TW2834

As china's rapid economic development, electricity network size, traffic transportation, banking operation, finance services, etc. have been rapid development. These businesses in face of the matter of improve efficency, enhance security and other series of problems. Video surveillance system responsible for video surveillance, video record, alarm and other functions. Traffic transportation, finance services and other services demand the higher quality of video surveillance system, such as digital video surveillance, intelligence, networking. In video surveillance system, overlay characters, motion detect, video display is inevitable technical problems.This article discusses the related technology of video surveillance system based on TW2834 video controller, discusses the charateristics of TW2834 controller and analysises the different implement methods of characters overlay, motion detection and multi-picture display. Complete the hardware design and software design of characters overlay, motion detetion and multi-picture display based on TW2834. On the foundation of these works, summarizes the key technologies of TW2834 controller used in video surveillance system. The research work of this article can be used for reference to future development of video surveillance system.
