The rapid advancement of AV-over-IP technology has transformed traditional AV infrastructures in our surroundings — the campus environment is one of them. Q-NEX solution for campus-wide AV distribution is based on the AV-over-IP technology to realize not only audio and video broadcast, but also live streaming to all of the classrooms as well as spaces outside classrooms such as cafeteria, library, teacher’s offices, corridor and reception hall. Through the deployment of Q-NEX Media Server, Networked Media Processor(NMP) and Media Box(MBX), this solution is capable of distributing audio, video and control signals over the Internet with the campus existing network.
