The Research Of Stream Media Server For House Security System

With the development of the society, '3111 Project' was raised for building security city and it was more and more attached importance to by people. The main products for traditional home security system are lock against theft and burglar alarm. They are not real time products and limited in functions. Aiming at ameliorating the traditional security system, this paper focus on the research and implement of the low cost and high efficient stream media server, so that with it, the customers are able to momtor the affairs happening in home any time with internet.Above all, the paper not only investigated the requirement of the market and the foreground of the development of the security system but researched the feasibility of the study of stream media server for family as well. After carefully compared and analysed the blue prints offered by the different CMOS chip manufacturers, the best system that was suitable for the home customers were selected and the main chip of the system was lucubrated. Whereafter, the paper described the design of the system chart and the hardware chart. Besides those, the electromagnetic interference problems which should be avoided during the process of PCB board facture were studied and electromagnetic compatible scheme was quested.As to the innovation point, the paper brought forward the scheme to improve the whole system. The ZigBee wireless technology was used to take the place of RS232 interface in the scheme, which was provided by the manufacture, so that the reformative system will be much more suitable for the customer for the convenient consideration. Finally, the paper worked over the classical RFC3640 packing arithmetic of MPEG-4 stream and the particular steps and flow chart of the improved scheme was provided to improve the transmission efficiecy.
