CCTV's "2022 Spring Festival Gala" brought the CCTV Spring Festival Gala into its 40th year. In 1983, CCTV's "Spring Festival Gala" opened the first Chinese television "Spring Festival Gala", this "Spring Festival Gala" did not have a gorgeous stage, no dazzling lights, basically no "technical content". However, since the second year, the stage setting of the "Spring Festival Gala" has developed from a stage to a mechanical and dreamlike scene.
Today, after nearly 40 years of development and accumulation, the "Spring Festival Gala" has become a comprehensive platform to show the development of science and technology and the ability to apply science and technology, and will bring a new aesthetic experience to the national audience every year.
Since 2005, led large screens have been used in the ground and side screens of the "Spring Festival Gala" scene. This means that the "Spring Festival Gala" stage has moved from the mechanical stage to the electronic stage.
In 2012, the ground, canopy, stage front and both sides of the CCTV "Spring Festival Gala" in the Year of the Dragon all adopted holographic LED screens, that is, 3D three-dimensional effects. Especially when Yang Liping performed the dance work "The Love of the Sparrow", the peacock opening screen picture presented on the big screen behind the stage and the dance on the stage were natural, forming a highlight of the Chinese TV screen that year.
The 2017 CCTV "Spring Festival Gala" stage highlighted the role of technology, and the liftable screen reached a record 173 pieces, of which 132 pieces on the ground and 41 pieces in the sky, presenting the audience with a beautiful scene of heaven and earth. The main stage of 132 LED high-definition large screens can be lifted and lowered up to 4.5 meters, how to control the shaking amplitude of each LED screen, is a world-class engineering problem, because once the screen fights, the stage will appear stuck, and even cut off the transmission line, resulting in the chaos of the entire performance. In order to ensure the safety of the performance, leaving the gap between each screen too large will affect the TV effect. At present, the distance of 1.5 cm between each screen is the most ideal distance obtained after trial and error.
In 2019, CCTV's "Spring Festival Gala" realized all-media communication for the first time, and carried out technological innovation in 4K, 5G, VR, AR, AI and other aspects. For example, for the first time, the Spring Festival Gala was broadcast live on a 4K ultra-high-definition channel, and 5.1 surround sound was used throughout the whole process to achieve 5G content transmission.
The stage design of the 2020 CCTV "Spring Festival Gala" for the first time created a three-tier three-dimensional dance effect, using flying screen technology to create a 360-degree surround landscape, so that the audience can have a new interactive experience of "naked eye 3D" in front of the screen, showing the charm, vitality and innovation of the "Spring Festival Gala" in the new era.
In 2021, the Spring Festival Gala will continue to innovate the use of technology and greatly integrate cutting-edge scientific and technological means, from the impressive, virtual and real combination of stage art, the ubiquitous interactive experience of the audience on the big and small screens, to the first application of high-tech cast members such as machine cows and AI+VR naked-eye 3D, all of which bring huge audiovisual shock to the audience.
