Real-Time A/V Quality Monitoring with ClearView Video Analysis
RTM is an Automated, Quality-of-Experience (QoE) Monitor, which measures the quality between two points. It does this after the decoder (STB) has had a chance to hide (or fix) the problems, which is exactly what the customer sees. RTM measures the Video Quality, Audio Quality, Audio Delay, Video Delay, and VANC Data. If any of these drop below a preset threshold, then an alarm is triggered and the sequences are saved. RTM saves valuable man-hours by saving the sequences around errors for QA/QC review.RTM Solutions
