Video Quality Monitor

Based on an elaborate human vision model and on display devices models, Video Quality Monitor quickly provides accurate and repeatable measurements.

It also measures the video bitrate and automatically produces "perceived quality vs bitrate" curves (instant bitrate and average bitrate). More, Video Quality Monitor automatically generates measurement reports.

Video Quality Monitor supports several video source types : video files, streaming video, video capture device.

Therefore Video Quality Monitor is a unique tool to measure and monitor the perceptual impact of distortions (due to encoding, transport or decoding) and control the functioning of broadcasting chains.

Video Quality Monitor integrates several perceived video quality metrics:

• No Reference metric for MPEG-2 video: measurement of blockiness visibility and blur perception.
• No Reference metric for H.264 video: measurement of objects sharpness and blur perception.
• Hybrid metric for MPEG-2 video: measurement of blockiness visibility, blur perception and detection of error blocks (badly reconstructed).
• Hybrid metric for H.264 video: measurement of objects sharpness, blur perception and detection of error blocks (badly reconstructed).

For any metric:

• Jerkiness, signal dynamic (min-max), temporal activity are also measured.
• MOS (Mean Opinion Scores) values are predicted.

More, Video Quality Monitor detects video presence (or absence) or audio presence (or absence).

These measurements are essential for any broadcaster or content provider who wants to easily measure sets of video files or to monitor the visual quality of a video source.
