基于CM-IMS的视频会议终端研究与应用

Research and application of video conference terminal based on CM-IMS

为满足政企客户信息化、低成本、高效率的沟通需求,中国移动云视讯基于CM-IMS面向全网用户提供视频会议业务,推出多款自研低成本会议终端。为解决网络链路传输质量对视频传输的影响,提出媒体质量优化方案提升自研终端的抗分组丢失性能,在总延时不超过200ms、网络分组丢失率20%以内情况下保障视频会议清晰流畅。并深度融合教育、医疗行业需求,推出行业定制化终端解决方案。

In order to meet the demand of communication with informatization,low cost and high efficiency for government and enterprises,we launched China Mobile Cloud VAAS self-research low-cost conference terminal.In order to solve the impact of network link transmission quality on video transmission,the media quality optimization scheme is proposed to improve the anti-packet loss performance of selfresearch terminal.When the total delay is no more than 200 ms and the network packet loss rate is within 20%,we guarantee clear and smooth of the video conference,and enhance the user experience of the Cloud VAAS.And according to the special needs of the education and the medical industry,we released the customized solutions.
