Abstract: By reviewing the development course of Yunnan earthquake emergency video conference system, from the perspective of system composition and construction, this paper expounds the impetus of video interconnection technology in the process of earthquake emergency command and the actual combat effect in typical destructive earthquake emergency response work. Theresults show that distributed, virtual and multi-network interconnection technology conforms to the application requirements of future earthquake emergency video conference system, the development of cloud video technology can help improve the earthquake emergency technology support ability.
