(: Aiming at the security and real-time problems in the remote management construction of video and access control in the telecom room, this paper puts forward a method to realize the secure and transparent transmission between socket and RS485 bus by using SSL and to realize the video multicast of device and client based on Linux platform by using jrtplib library. The results show that the former can make the whole system not limited by the region, and the latter can meet the real-time transmission of video and facilitate the remote operation and control of users.)
