摘要
为满足多点控制单元(Multi-point Control Unit,MCU)资源池模式下视频会议的录播需求,针对MCU资源池会议电视系统的特点,研究了自动召开会议和并行召开会议2种模式,并据此提出了会议录播需求。通过分析虚拟录播机和资源池调度方式相互融合的可行性,设计了录播系统总体架构,提出了集中录播设备虚拟化、虚拟录播设备注册与工作方式、音视频资料存储和用户远程访问4项关键技术,形成了MCU资源池会议模式下音视频录播的完整策略,为降低设备采购、管理和运维成本以及提升服务质量提供了解决方案。
In order to meet the recording and playing requirement of video conference in MCU resource pool mode, this paper studies the modes of automatic conference and parallel conference based on the characteristics of MCU resource pool video conference system, and presents the recording and playing requirement of video conference. By analyzing the feasibility of the fusion of the virtual recorder and the resource pool scheduling mode, the overall structure of the recording and playing system is designed. Four key technologies are presented, such as centralized recording device virtualization, virtual recording equipment registration and working mode, audio and video data storage and user remote access. Finally a complete strategy of audio and video recording in the MCU resource pool conference mode is formed, which can provide a solution to reduce equipment procurement, management and operational costs, improve service quality.
