摘要
介绍了利用网络传输和网络电视实现视频通话的技术方案。该方案基于C/S结构搭建了系统的硬件平台,包括SIP服务器、STUN/TURN服务器以及BOSS服务器;软件平台采用了高效的编解码技术以最大限度减少带宽占用,设计了可依据传输数据时网络带宽变化自动调整的编码参数技术,采用了声音优先的策略以适应带宽的剧烈变化,从而保障了通话质量。
The technology solution of video calls based on the network transmission and Web TV is introduced.The technology solution takes the C/S framework as the system＇s hardware platform,including the SIP server,STUN/TURN server and BOSS server.In the software platform,efficient coding technology is used to minimize the use of network bandwidth.The adaptive adjusting coding parameter method is designed according to the network bandwidth.The voice-priority strategy is used to adapt dramatic changes of the network bandwidth.
