The EXPO 2010 was held in Shanghai, China from May 1 to October 31, 2010. This was the first time China held the World Expo, creating a record of the largest scale in the history of the World Expo. The number of visitors reached 73.08 million, setting a record high.
After one month of preparation, China Satcom set up an emergency jump station in Kashgar, Xinjiang, which officially opened at the end of April. The Kashgar-Europe jump station can receive or retransmit live broadcast signals of the EXPO 2010 through multiple satellites at the same time, making this event possible to spread to the world through satellites.
The video transmission system is mainly classified as a broadcast SD transmission system and a broadcast HD transmission system by transmission effects, and is mainly composed of satellite antenna, satellite uplink transmission equipment, and satellite downlink transmission equipment.
