The General Frame Of The Real-time Long-distance Video Supervisory System Based On H.264

H.264 is the new standard of video codes formulated by the international electricityassociation ITU-DT's video codes expert group (VCEG) and the InternationalStandardization Organization ISO/IEC's moving picture expert group (MPEG).Its goal isfor obtaining the better image compression effect and adapting the different networkenvironment well.This article introduced the new technical of the video codes -H.264, and emphaticallydiscussed the new technology used in H.264.Then,the article key introduced the projectapplication example based on H.264-the general frame of the public information station'sreal-time long-distance video supervisory system based on H.264. Depending on theanalysis of the networking trend and the real-time demand of video monitoring system,DSP TMS320C6416 and ARM micro-controller are used to implement an embedded videoencoder with IP network. This paper presents the principle of system structure andhardware design, while finishes DSP encoding algorithm and NAL interface forRTP/UDP/IP. Simultaneously the paper studies the key transmission technology of how tobuild the real-time tong-distance video capture(monitor) system. The problem has beensolved on sequence and lost package of video stream data in non-broad bandenvironment. The test shows that the platform can support transmitting video flows in ahigh quality via Ethernet networks.This system has realized the digitization and network supervisory system ofinformation station. The system can protect and centralized manage the information station.Simultaneously this system has built the solid foundation for Suzhou's digitizedconstruction.
