Mobile system measures video quality for diverse app types
Automated Mobile Video Objective Testing System

Summary
Measuring how good videos look on phones is tricky because apps like on-demand video, video calls, and cloud games all behave differently. The authors developed AMVOTS, a system that can check video quality across many kinds of apps and network setups. This helps mobile providers understand and improve user video experiences. The system can also be part of a feedback loop that adjusts network resources based on video quality measurements.
What this means in practice
- •For mobile network operators: Monitor and optimize video quality across different app types to improve user satisfaction under varied network conditions.
- •For cloud gaming service providers: Use video quality measurements from mobile conditions to fine-tune streaming performance and resource allocation for better gameplay experiences.

Abstract
Applying QoE analysis to optimize usage of cellular spectrum is of high interest to mobile network operators. A key challenge is to be able to perform QoE measurement across very different types of apps, from DASH VoD to interactive applications such as Video Conferencing and Cloud Gaming. This paper presents AMVOTS, a QoE measurement system developed by AT&T, which is flexible enough to support a large range of application types and network conditions. We also discuss using AMVOTS as part of a closed loop to prototype QoE-aware radio resource allocation.
