基于小波压缩算法的境外实时视频传输系统

Oversea Real-Time Video Transmission System Based on Wavelet Compression Algorithm

为解决在网络带宽较低环境下的视频监控及传输问题,采用基于小波变换的高效率压缩方法,传输D1/720P/1080P高清晰监控画面,实现对赤道几内亚的吉林送变电国际公司工作环境的实时视频监控。该监控系统能按指定需求使用网络带宽,具有循环记忆存储功能,其小波编码技术具有自身独立编码解码规范和较高的安全性能和保密性,可在200 Kbit/s下传输D1 20FPS的图像,传输延时小于1 s,相比国际通用标准H.264技术,节约带宽小于60%。

We use wavelet compression method based on high efficiency at lower network bandwidth conditions for transmission D1/720P/1080P high-definition monitor screen, to achieve equatorial guinea Jilin Transmission and Distribution International working environment for real-time video monitoring. The system can monitor the use of network bandwidth according to the specified requirements, a circulating memory storage function. The wavelet coding techniques have their own independent encoding and decoding specification, with high security and confidentiality, can be transmitted D1 20FPS next image transmission 200 kbit/s delay is less than 1 s, compared to the international standard H. 264 technology can save bandwidth of less than 60%.
