Live broadcasting has become one of the most important pillars for many professionals in the industry, including streamers and content creators who want to shape experiences that bring them closer to their viewers. For improve these experiences NVIDIA has strengthened its ecosystem with various optimizations that revolve around the RTX platform and managed to mark an important turning point.

One of the most important innovations is undoubtedly the support of the HEVC standard with Twitch Enhanced Broadcasting NVIDIA NVENC. Until now, every streamer faced a difficult decision, having to choose between offering video with higher image quality or reducing image quality to achieve faster and more stable streaming.

Obviously, streaming with higher video quality does more attractive and creates an excellent experience but may eventually cause problems to those users who have low bandwidth internet connections or who are using relatively old devices and equipment that are not ready for this level of streaming.

What would be the ideal solution in these cases, reducing quality to democratize streaming at the cost of harming other users who have the means to enjoy higher quality? It’s an option, but definitely not the best.

NVIDIA and Twitch bet on multiple streaming

This is truly the perfect solution. Thanks to the development of Twitch Enhanced Broadcasting and NVIDIA’s NVENC support, broadcasting is possible different streams simultaneously with different resolution levels and frames per second from a computer configured with a GeForce RTX graphics card.

This way we could generate, for example, five streams clearly differentiated that our followers can use depending on the device they are connecting from and the resources and bandwidth they have:

• 480p and 30 FPS for mobile devices.
• 720p and 30 FPS for tablets.
• 1080p and 60 FPS for laptops.
• 1440p and 60 FPS for PC.
• 4K and 60 FPS for TVs.

It is also important to note that we will also be able to improve image quality and efficiency by 25% compared to the H.264 standard. This means that the video will play with 25% higher bitrate, and therefore it will offer a sharper and cleaner image and without transmission delay.

All workloads are performed via specialized hardware acceleration offered by NVIDIA GeForce RTX graphics cards, which means that both GPU and CPU are completely free to optimally move our favorite games.

GeForce RTX also offers other very interesting features for the world of streaming, as they allow us to take full advantage of the NVIDIA Broadcast platform, which allows us to turn our room into a studio and access to advanced features noise and echo reduction, use virtual backgrounds and auto-focus functions, as well as activate image denoising and eye contact technologies.
