摘要
为解决传统的集中式SIP视频会议架构容易造成系统的负载过重问题,依据集中式会议架构,将Video Mixer模块化与分散化,提出分层式SIP网络视频会议系统,以分散视频数据处理负担,并提高视频会议通讯质量。以IXP465嵌入式系统平台实现系统原型,在有限硬件条件下,验证了系统的功能及可行性。实验结果表明,该系统易于实现随意会议,并可以有效地对Video Mixer资源进行动态分配。
To address the problem of overload in the traditional centralized architecture of SIP-based video conference the system, according to centralized architecture of video conference, the video mixer is changed into modules and dispersed, and a two-layer network video conference system based on SIP is proposed, and this system disperses the video data processing work, and improves the communication quality. The prototype system is implemented by IPX465 embedded system, so the feasibility and its function is validated in the limited hardware environment. Experiments show that the proposed method realize Ad-hoc conference easily and allocate video mixer dynamically effectively.
