| Summary: | 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.
