| 摘 要： | 针对应用层组播系统采用网络硬盘录像机存储模式存在流媒体转发服务器负载较重、传输效率低的问题,提出了基于连续式录像机存储的应用层组播系统设计方案。对于不需要预览的视频通道,利用存储服务器直接从前端编码源获取视频数据,在保证编码源和接收端是单份视频数据的前提下,有效地缓解了流媒体转发服务器的负载,从而保证了矿区视频监控系统的正常运行。现场实际应用验证了该系统的有效性。

| Abstract: | For problem of heavy load and low transmission efficiency of stream media server existed in application layer multicast system by use of storage mode of network video recorder,the paper proposed a design scheme of application layer multicast system based on storage mode of continuous video recorder.The system uses storage server to acquire video data which do not need to preview from front encoding source,effectively eases the load of stream media server on the premise that encoded source and the receiver both has single video data,thus ensures normal operation of mine video monitoring system.The actual applications verify effectiveness of the system. |
