The invention discloses a high-definition video conference 
system adopting a Zhongtong 
satellite network. The high-definition video conference 
system comprises a 
satellite ground station, a movable Zhongtong emergency 
satellite communication vehicle and a static Zhongtong emergency satellite communication vehicle, the satellite 
ground station comprises a satellite communication 
system, an Ethernetswitch, a video module, a voice module and a data module, a movable Zhongtong satellite antenna module, a 
satellite MODEM, the 
Ethernet switch, a VOIP voice gateway, a 
teleconference terminal, a vehicle-mounted phone, a vehicle-mounted indoor / outdoor camera, a display screen, a 
wireless single pawn 
video transmission system and a camera are installed in the movable Zhongtong emergency satellite communication vehicle. When the high-definition video conference system is in use, fast two-way 
broadband satellite link access can be achieved, an SCPC 
satellite channel is established, and dynamic image, voice and 
data transmission are achieved; and dynamic and 
static image, voice and 
data transmission are achieved, multiple communication 
modes coexist, multi-channel dynamic communication is provided for emergency command, and the system bandwidth resources are saved.
