摘　　要：针对当前不同地区的异构农业视频服务系统无法互联互通因而服务范围受限问题,在深入分析和研究当前不同视频服务系统原理、特点和协议的基础上,提出并实现了自定义控制协议解决异构视频系统互联互通问题的方案。通过自定义协议完成同构及异构视频系统的实体信息和控制信令的转发、标准视频会议音视频流和流媒体音视频流的转换,从而解决异构视频系统的互联互通问题。实验结果表明,采用自定义控制协议完成异构视频服务系统的互联互通问题具有保持原系统自治性、简单方便、可扩展等优点。To solve the problems of the services range limitation caused by the disabled interconnection among the heterogeneous agricultural video services systems distributed in different areas. An interconnection program based on user-defined protocol is raised and realized after deeply research on different video systems. By transponding the entity message and control command under the same user-defined protocol between different video systems and transforming the audio streams and video streams between standard video conference systems and streaming video systems, the heterogeneous video systems can interconnect with each other and work together. Experimental results show that the interconnection program based on user-defined protocol can keep the autonomy of original video systems, easily to realize and has a good scalability.
