Video & Audio Quality of Experience

No longer an option, multichannel service providers must provide exceptional video and audio quality to subscribers. Competition is at an all-time high giving subscribers in every market the option to choose their television provider. Service providers cannot afford to introduce poor quality channels or other service offerings to subscribers for fear of costly churn.

Mixed Signals offers best-in-class monitoring solutions to provide you with the confidence and service assurance you need to ensure you are providing the best possible video and audio quality to your subscribers, while keeping your operational costs low.

Video and Audio QoE Scoring System

The Video and Audio Quality of Experience (QoE) scores serve as an indication of the satisfaction level of the TV viewer.
The scores are based on human perceptual analysis of hundreds of audio and video PIDs (in monitored programs) simultaneously in real time. Should issues such as temporarily frozen video, tiling/macro‐blocking, audio disruptions, etc., affect the quality of the viewers’ TV viewing experience, the score is reduced.

The magnitude and duration of the score reduction is based on an analysis that includes the position of the error on a viewer’s screen, the duration of any reduction in quality and the frequency that quality issues occur on a program. The system models these results based on the average TV viewer’s reaction into an easy to understand, continuously graphed Audio/Video QoE score chart.

All QoE scores less than 100 on a program indicate that video and audio problems are degrading the actual viewing experience for the viewer. The worse the subscriber experience is, the lower the score becomes.
