Q-Master Video Software

QoE Systems' Q-Master System (Video version) measurers the video and audio quality aspects of video streaming and video telephony communication devices or channels. Q-Master uses perceptual analysis capabilities as defined by ITU-T. The result of the measurement is a VMOS (Video Mean Opinion Score); to interpret end-to-end quality of video. The output includes information such as block distortion, blurring, edge busyness, jerkiness, PSNR and noise.

The Q-Master Software Suite is a file based solution that requires the user to facilitate the sending and receiving of the video streams. QoE Systems provides example video reference files that can be used from any streaming server on the network.

The Q-Master's graphical view includes the capability to see side-by side and frame-by-frame the original and resulting video. The measurement results for each individual frame can be selected in the display window.

The Q-Master Software Suite operates in a Windows environment, using file-based analysis capabilities. It allows report printing and graph exporting to standard PC programs.

Measure quality with perceptual algorithm

Quality assessment of video streaming and video telephony is done with QoE Systems' VMOS algorithm. The output is a Video Mean Opinion Score value combined with information such as block distortion, blurring, edge busyness, jerkiness, PSNR and noise. Available audio quality assessment provides a standard MOS score and lip synchronization analysis identical as in human perception.

 
Easy-to-use, Windows-based user interface

A Windows based user interface provides a simple yet full-featured test environment allowing fast and comprehensive quality assessment measurements.

 
Graphical presentation of all measurements

The graphical view includes the capability to see side-by side and frame-by-frame the original and resulting video. The measurement results for each individual frame can be selected in the display window.

 
Internal video server available

The Q-Master system facilitates the sending and receiving of video streams either from its internal Darwin Server, or any streaming server on the network.

 
Unique camera interface

QoE Systems provides a unique camera interface with the Q-Master system. This allows the user to capture the actual display as show to the end user.
