Conviva and Sky partnered to develop an innovative way of delivering the highest over-the-top (OTT) video quality possible for Sky viewers while minimizing content delivery network (CDN) costs. Conviva’s quality of experience (QoE) analytics helped Sky discover a direct correlation between viewer engagement and buffering. Sky realized that viewer engagement dropped significantly when the buffering ratio hit or exceeded 0.4%. Sky then integrated Conviva’s Precision – a resource optimization intelligence feed – to inform their proprietary technology stack to make real-time CDN switching decisions based on thresholds and costs.
