The second joint rehearsal of the 2021 Spring Festival Gala was held on Wednesday in Beijing and showed several new technologies.

The 2021 gala features the innovative use of the super high definition cloud communication technology to coordinate the stage performance. 

Some actors, who are not in the Chinese mainland, may not be able to perform live this year due to COVID-19 pandemic prevention and control measures. But the cloud technology allows actors who can't be physically present during the live performances to participate via prerecorded videos while also remotely interacting with the audience.

According to China Media Group (CMG), this method is not a simple inter-cut, but close interaction with live actors which is an integral part of the program.

The stage of this year's Spring Festival Gala has installed a huge ring of the new media screen wall. A total of 154 ultra-high definition large screens are distributed above the rear area of the auditorium, and can synchronously access 154 channels.

Relying on the strength of 5G bandwidth, the cloud communication technology will achieve cross-time interactive performance on the same stage. Upgrades in technology and stage will give the world a "panoramic feast" of the 2021 Chinese Spring Festival Gala.
