The Academic Papers
Time-State Analytics
Our recent academic paper, presented at CIDR 2023, posits that while our Timeline method of measuring streaming video has been incredibly successful the Timeline abstraction method is generally applicable across many more domains and enables new opportunities for further research.
Raising the Level of Abstraction for Time-State Analytics
Video AI Architecture
Our most recent academic research has been centered around artificial intelligence–specifically, artificial intelligence models for better understanding video on the Internet.
