The Science Behind The Video AI Platform

You can think of Conviva as an OTT professor — a teacher of the highest academic rank when it comes to knowing how to deliver the highest quality video possible. Conviva has written the papers that define the OTT industry and have academic intelligence and curiosity at the core. Conviva’s technology is exact, the data is exceptional, and the innovation is proven. Conviva is full of tenured experts with a focus on precision and academic integrity. Understanding how to leverage the internet as a mass-scale video transport medium has positioned Conviva to be the architects of experience.

Video AI Architecture

Our most recent academic research has been centered around artificial intelligence – specially, artificial intelligence models for better understanding video on the Internet.

Viewer Experience Optimization

Conviva’s award-winning team of engineers and scientists have discovered and validated the need for a preemptive viewer experience optimization tool and quantifies and validates video quality impact on viewer engagement.

Scalable Management and Delivery Systems

Dr. Zhang’s End System Multicast (ESM) research group at Carnegie Mellon pioneered the overlay multicast architecture and techniques to support scalable Internet video streaming. The award-winning Ph.D. dissertation of Dr. Ion Stoica, co-founder and chief technical officer, pioneered the first scalable architecture to manage QoS states in a distributed networking environment.

Big Data and Cloud Computing

Dr. Stoica’s research group at the University of California, Berkeley has done pioneering research on building large scale, real-time cluster computing frameworks, and on enabling multiple frameworks, such as Hadoop and Hypertable, to seamlessly share the same cluster.

Software-Defined Networks and Intelligent Network Control

Dr. Zhang and Dr. Stoica have worked on new network architectures which enable direct control for routing data traffic, supporting network-level objectives, and providing network-wide visibility.
