| With the trend of vigorously popularizing the integration of Internet of Things and Three Networks, video surveillance area will surely welcome a broader development space. Development of AVS in video monitoring area is mainly restricted by AVS lacking embedded encoder and coding chips of high performance and its still lacking mature AVS surveillance solution. Obviously, it is of great significance and commercial value to design and implement AVS embedded encoder and AVS video monitoring system.In this project, AVS coding algorithm is further researched and AVS key coding algorithms are optimized, successfully achieving AVS real-time encoder of Dl resolution of DSP platform. For the core to embedded coder,this paper puts forward a general framework of AVS video monitoring system,arranges its overall architecture and divides its function module and system partition. Then introductions of package process in the AVS codec XDM standard and communication process under the framework of Davinci ARM and DSP are detailed made in this paper. Further more,it specifies the realization of its system signal controlling,the way of network transmission method and the storage mechanism in AVS video streaming.AVS video surveillance system achieves AVS embedded real-time coding of Dl resolution based on TMS20DM6446Davinci Platform and AVS embedded real-time decoding of Dl resolution based on OMAP3530platform. Additionally, it attains such functions as signaling control, flow accounting and the rest using SIP protocol stack, carries out network transmission of AVS video stream with RTP/RTCP transmission protocol and accomplishes the multi-platform support of client to Windows, Linux and embedded. Through the components mentioned above, network AVS video monitoring system comes into being with complete functions such as AVS real-time coding, WAN transmission, real-time video and real-time decoding playing, real-time monitoring and so on. Meanwhile, the system enjoys the features of low cost, high coding efficiency, strong real-time and so forth, further improving the commercial value of this system. AVS video surveillance system enriches AVS product chain, benefiting the popularization of AVS standard and the promotion of AVS industrialization. |
