Abstract: In today’s digital landscape, video streaming has become a cornerstone of online content delivery, with applications spanning entertainment, education, teleconferencing, and live broadcasting. The importance of optimizing video streaming cannot be overstated, as Quality of Experience (QoE) directly impacts user engagement and satisfaction. However, the video streaming pipeline faces significant challenges, including maintaining high QoE, minimizing latency, and managing costs effectively. This talk addresses these critical issues by exploring holistic strategies that enhance the video streaming experience from source to destination. We will delve into the complexities of content provisioning, content delivery, and content consumption, emphasizing the necessity of an end-to-end approach. Additionally, by considering the entire streaming pipeline, we will discuss novel algorithms designed for optimizing end-to-end video streaming and demonstrate how these approaches can more effectively tackle the primary challenges of QoE, end-to-end latency, and video streaming costs.
