Bringing Internet Video to Prime Time
 

Ion Stoica

About the talk:
Video traffic already represents a significant fraction of today’s traffic and is projected to exceed 90% in the next 5 years. In parallel, user expectations for a high quality viewing experience (e.g., low startup delays, low buffering, and high bitrates) are continuously increasing. In this talk, I will share some of my experience gathered at Conviva, a startup that builds and operates a video optimization platform designed to address the challenges of large scale and high quality video delivery in the Internet. First, I will share some of the findings from our data analysis, which shows that a large portion of the audience experiences quality problems on a regular basis and that quality does impact viewer engagement. Second, I will argue that to achieve the best streaming quality it is essential to develop a real-time control plane decoupled from the data plane that has a view of the entire audience and can control the delivery at an individual viewer level.
