Explore a cutting-edge conference talk on improving real-time communications for high-quality video streaming applications. Dive into the challenges faced by ultra-high-definition (UHD) videos with high frame rates in edge computing environments. Learn about the innovative Adaptive Frame Rate (AFR) controller designed to achieve ultra-low latency by coordinating frame rates with network fluctuations and decoder capacity. Discover how this solution addresses key challenges in queue measurements and decoder queue management. Examine the impressive results from trace-driven simulations and large-scale deployments, showcasing significant reductions in tail queuing delay and stuttering events. Gain insights into the practical implementation of AFR in a cloud gaming service, demonstrating its real-world effectiveness over a one-year deployment period.
