Real time, video quality monitoring application for digital television services

This paper presents a real-time video quality monitoring application that delivers 24/7 services to the satellite, terrestrial and cable digital television providers. The application monitors the Perceptual Video Quality (PVQ) score (on a scale between 1 to 5 like in the subjective tests), the viewers Quality of Experience score (not including the PVQ score) and the Quality of Service (QoS) parameters, so it can detect the cause of possible reduced image quality. Compared to other systems that can monitor the video quality only for one television program at a time, the proposed solution can simultaneously monitor the video quality on several television programs on different satellite transponders, terrestrial or cable television channels. The measurement test results are presented for satellite and terrestrial broadcasting services.
