Enhancing Broadcast Workflows to Deliver High Quality Live Content with NVIDIA RTX
Story Highlights
Ideapool is dedicated to commercializing, researching, and developing computer graphics and image technologies. As a member of the NVIDIA Inception program, Ideapool implements innovative applications of digital content such as virtual reality, augmented reality, virtual simulation, digital twin, and 3D visualization.
Ideapool has expanded its business to cover pan-media, education, healthcare, industrial internet, and smart city.
Using NVIDIA RTX A6000, NVIDIA G-SYNC, and NVIDIA Mosaic technologies, Ideapool supported the Spring Festival Gala and Lantern Festival Gala, bringing digital content to life for audiences around the world.
With cutting-edge performance and features, the RTX A6000 is a powerful visual computing GPU for desktop workstations. The NVIDIA G-SYNC, an advanced display technology, allowed Ideapool to significantly minimize display stuttering and input lag. And with NVIDIA Mosaic, the team could easily span any application across multiple high-resolution displays or projectors from a single system. This feature enabled Ideapool to treat multiple displays as a single desktop, all without causing application software changes or visual artifacts
Bringing Digital Content to Big Screens
For the first time in history, the 2022 CCTV Spring Festival Gala used LED screens to create a 720-degree dome space—a setup similar to the one used by the Lantern Festival Gala in the same year. During the gala, each
LED screen would broadcast various assorted video content in line with the event theme. The LED screens covered a total area of 4,306 square meters, equivalent to 10 standard basketball courts. This setup shattered the record of all previous Spring Festival Galas in terms of the area and the number of LED screens.
Additionally, the 2022 Spring Festival Gala would be broadcast live in 8K, which required higher picture clarity and color fidelity. Ideapool needed to find a way to synchronize real-time rendering and broadcasting of a massive amount of UHD signals, as well as the ultra-high-speed real-time encoding and decoding of dual 8K video.
The Ideapool team faced the following challenges:
- Encoding and decoding efficiency: The 2022 Spring Festival Gala would
last almost five hours, during which technologies like extended reality (XR),
holographic scanning, and 8K 3D rendering technology would be applied
to heighten the visual effect. The show presented significant challenges in
video encoding and decoding efficiency, and a vast amount of UHD video
data was involved. - Render quality and speed: To guarantee the image quality and color
rendering of the 8K live broadcast of the Spring Festival Gala, Ideapool
formulated a dual 8K output solution, which required extremely high-quality
renders and speed. - Synchronization: For the first time, synchronous broadcasting control
was implemented via the 4,306-square-meter LED screen, during which
every screen must have the same refresh rate and achieve perfect
frame synchronization.
self-developed real-time 3D graphics and image engine, large-screen intelligent broadcasting control system, and UHD cluster rendering technology to allow for 8K UHD rendering and intelligent broadcasting control. This solution was also used for the Lantern Festival Gala, where NVIDIA GPU and display technology significantly improved the rendering and broadcasting control capabilities.
in hardware bottlenecks. But with joint decoding, some results processed by CPU and GPU can be directly output to the broadcast channel, significantly reducing the load on the CPU. The RTX A6000 notably improves the
connection between the GPU and other computer components to speed up encoding and decoding processes.
