From 1983 to 2023, the Spring Festival Gala has gone through 41 years, and the presentation form of the program content has also undergone a leapfrog change from real scene to virtual and real integration, and skill symbiosis. With the theme of "A Thriving New Era China, a Better Life Changing with Each Passing Day", the 2023 CCTV Spring Festival Gala makes extensive use of new technologies such as 4K 8K, AI, and XR to continue to promote the integration and innovation of "thought + art + technology", and dedicates a "Chinese New Year's Eve Dinner" with excellent ideology, artistry, ornamentation and a sense of science and technology to Chinese people around the world.
2023 is the 11th year that Addip has served the Spring Festival Gala continuouslyThis year, Aidip continued to join hands with the main station for CCTVSpring Festival Gala offersOn-site 4K 8K ultra-high-definition rendering and intelligent broadcast control, "vertical screen to watch the Spring Festival Gala" ** packaging and other full technical and artistic servicesIn the interweaving of virtual and reality, the integration of technology and culture, it will bring the audience a wonderful cultural audio-visual feast.
Ultra-high-definition cluster rendering and intelligent broadcast control
Escort the safe broadcast of CCTV Spring Festival Gala
In terms of visual presentation, the 2023 CCTV Spring Festival Gala will continue to use large-area LED displays, multi-screen presentations to create an immersive Spring Festival Gala, and let the imagination come to fruition. The huge stage is made up of several giant LED screens of different shapes. In order to create a rich level and shape of the entire stage, all stage LED screens are of several different sizes and specifications, and these irregular large screens are the most important carrier of the visual feast of the Spring Festival Gala, and the background atmosphere and on-site visual effects of all programs are presented on these large screens.
At the same time, the frame rate of the material will be increased to 50 frames per second, effectively improving the clarity and smoothness of the picture. If you want to synchronize more than 20 channels of 4K 8K 50P signals to thousands of large LED screens, you need a high degree of cooperation between the screen and the broadcast control system to present the best visual experience.
In order to ensure that the ultra-large-scale screen can receive the same frame picture, the unification and synchronous broadcast control of ultra-high-resolution and high-frame-rate digital content can be realized, so that the screen display picture is more delicate, the color restoration is more realistic, and the visual level is richerRelying on the profound experience accumulated in serving important national projects for many years, ADDIP has upgraded its first-class encoding and decoding capabilities, ultra-high-definition cluster rendering capabilities, and synchronous broadcast control capabilities.
In terms of codecs,Improve the decoding speed by upgrading the algorithmEffectively handle the encoding and decoding challenges brought about by large amounts of ultra-high-definition, high-frame-rate footage. In terms of rendering,Realize multi-node distributed ultra-high-definition cluster synchronous renderingMultiple GPU rendering nodes work together to achieve complete synchronization of particle effects, physical effects, picture brightness, and high-quality images between each engine node, improving rendering speed.
In terms of synchronization, each rendering site is customized and developed, adding a professional first-class IO card, and each rendering node can support 8K 50P 10bit SDI signal output (4*12G), and support ITU-R BT2020, HDR HLG and other color gamut spaces, with the support of synchronization signals and other devices,Multiple engine nodes can do accurate signalingThe synchronous output, combined with the synchronization mechanism of the software, ensures the stable and synchronous broadcast of the system signal.
In addition to the deep technical accumulation of Aidip, the staff's dedication day and night is also the key to ensure the smooth broadcast of the party, from program discussion, resource coordination, technical upgrading, rehearsal joint commissioning, technical support to mobile emergency, the team uses excellence, rigorous and serious technical services to escort the safe broadcast of the Spring Festival Gala.

During the live broadcast, the program team set up a total of 8 dedicated vertical screen shooting positions, including 5 camera operation positions, 1 remote control camera, and 2 5G cameras, so that the picture capture is more accurate and the lens switching is more flexible.
This year, the cumulative scale of the Spring Festival Gala on the vertical screen reached 17.9 billion people, an increase of more than 50% compared with last year.
