Real-time video quality monitoring for mobile devices

Due to the explosion of various video applications and services it is becoming increasingly important to accurately measure video quality in real-time. Since reference information is absent in many practical situations, video quality assessment with No-Reference (NR) measures is attracting increasing attention from both industry and academia. However, there are very few commercial quality assessment systems for mobile devices available in today’s market. After describing a set of applications, we briefly survey the state-of-the-art in NR video quality assessment. Finally, we present a real-time quality monitoring system for video transmitted to mobile devices and describe a proof-ofconcept implementation. In this system, the quality of video at different nodes and terminals in a transmission channel can be monitored and tracked through a remote software interface. These video quality measurements can also provide valuable information for network diagnosis and quality-scalable servic...
