     The UV800 is used to transmit the live images of Wentian Lab Module collected on site to the cloud receiving server, and then the live guide station will switch with the live linking machine through RTMP pulling stream for synchronous guide. After finishing the program production, it will be synchronized live by CCTV news, Xinhua News Agency and other central media.

    The event is based on i-Mux multi-link bonding technology, no additional network security is needed at the event site, the live launch screen is directly transmitted back to the cloud server through i-Mux live terminal, and then pushed to the central program production center, so that all major platforms can live broadcast the event at the same time, so that viewers who do not have the means to reach the launch site can also watch the spectacular scene of the launch of the Wentian.
