Ultra-Low Latency Streaming. In Pursuit for the Perfect Video Delivery

During the talk, we will consider the problems of video transmission in conditions of ultra-low latency. We will talk a little about the architecture and principles of building real-time control applications using the example of cloud gaming.

We will consider what is meant by perfect video delivery, what prevents the implementation of such delivery, and what mechanisms and principles are used.

We will discuss in detail the metrics used in the VK Play Cloud project as well as analyze in detail two improvements in video transmission mechanisms tested in 2023. We will go through the obtained results and their impact on the vision of what perfect video delivery is in conditions of ultra low latency.
