IP Over AOS的软件设计实现

摘要

The AOS is a standard, which is widely used in space cooperation development and space resources. The application of AOS technology in air--to-ground transmission of video data is imperative. Aiming at the research on air--to-ground transmission of IP video data, this paper uses AOS encapsulation protocol to recover IP data on ground receiver, and transfers the data by Ethernet. Based on the characteristics of video data, this paper describes the requirements of transmission format in detail, proposes a software realization method which is different from the traditional method realized by FPGA hardware circuit. The simulation and test of data processing are performed and the efficiency of software processing is given. The results prove the feasibility of this method in practical application.%AOS是一种空间合作开发、空间资源广泛采用的标准，采用AOS技术，对视频数据进行空地传输是势在必行的。针对IP视频数据的空地传输进行研究，采用AOS协议封装，并在地面接收端再将IP数据恢复出来，通过以太网进行传输。根据视频数据的特点，详细描述了传输格式的要求，提出了不同于传统采用FPGA硬件电路实现的软件实现方法，对数据处理过程进行了仿真测试，给出了软件处理的效率，证明了在实际应用中的可行性。
