Exploring the next generation codecs, our first steps go towards testing LCEVC. The emphasis is on identifying where this standard can significantly impact, considering the unique video requirements for DaaS.
The low latency ensures real-time interactions, which is crucial for a seamless DaaS experience. The extraordinary text quality is vital for readability and effective communication. By aligning these features with the specific use cases in DaaS, the project aims to unearth the potential of the LCEVC standard in enhancing the DaaS user experience and expanding its usability.
This project compared and fine-tuned different codecs optimized for screen content streaming in the cloud. Using various metrics and tools, we measured the codecs' bandwidth, quality, CPU usage, and CO2 emissions. Our results show that screen content codecs can reduce the bandwidth and improve the content's quality while lowering the cloud servers' CPU usage and CO2 emissions. Our project demonstrates the potential of these technologies in modernizing thin client solutions and contributing to a greener world.
Video quality needed to remain constant or even increase during tests to match our customers' needs. All our current results follow that premise. With the improved bitrate reduction of our codecs, we can also propose quality improvements on text content, a traditional pain point on virtual desktops UX, using a higher chroma subsampling without impacting bitrate or latency. Different testing protocols and content types have achieved a BD-Rate reduction of -22.6 dB.
