Q-Master System. The best Video test solution.

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 related audio quality and video/audio synchronization is also analyzed. Audio quality assessment provides a standard MOS score, while the important lip synchronization correlates timing identical as in human perception.

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. This allows developers and operators to assess the correct functioning of networks and/or devices such as codecs, transcoders, gateways, etc.

The Q-Master System includes dedicated hardware with a variety of available network and device interfaces. It facilitates the sending and receiving of signals over Ethernet VoIP channels, Analog Line, S-Video, or with a camera adaptor.

The Q-Master GUI operates in a Windows environment, where the user interface provides a simple yet full featured test process environment that allows quick and comprehensive quality assessment measurements. The measurement results can be stored, reviewed, printed and exported.

The Q-Master can be deployed both locally as well as remotely connecting with Ethernet/LAN for control.
