As an indispensable part of every year's Spring Festival celebrations, the annual CCTV Spring Festival Gala has long become a must-have "reunion dinner" for households across China. In 2019, the CCTV Spring Festival Gala marked a groundbreaking milestone by delivering a live broadcast in 4K ultra-high definition for the first time—simultaneously enabling 5G content transmission. This cutting-edge technology allowed viewers to experience the transformative power of innovation right from their screens, presenting them with a high-tech "feast" that was nothing short of spectacular.
 

This year's Spring Festival Gala featured a main venue in Beijing, along with satellite venues in cities like Shenzhen and Changchun. The event creatively integrated 5G+4K and 5G+VR signal transmission technologies, successfully enabling end-to-end production and broadcasting of 4K ultra-high-definition content throughout the entire process. Compared to traditional HD signals, 4K TV displays offer significantly higher resolution and more accurate color reproduction. These cutting-edge technologies and innovative staging not only boost the efficiency of 4K content creation but also open up new possibilities for multi-screen and multi-angle viewing experiences in live broadcasts. Additionally, this year’s gala saw the production team placing special emphasis on enhancing the transparency and visual clarity of lighting and stage design, ensuring that the cityscapes captured in 4K ultra-high definition come alive with breathtaking depth and realism—delivering an unprecedentedly immersive audiovisual experience to audiences.
