Q-Master Video System

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.

Q-Master Voice System

QoE Systems' Q-Master System measurers the speech quality aspects of communication devices or channels. Q-Master uses perceptual analysis capabilities as defined by ITU-T P.862. The result of the measurement is a MOS (Mean Opinion Score); to interpret end-to-end quality of speech.

Developers and operators can assess the correct functioning of networks (both telephony and LAN/WAN) and/or devices such as codecs, echo-cancellers, transcoders, gateways, telephones, voice activity detectors, etc., using the Q-Master System.

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 POTS (FXO and FSX), Analog Line, PSTN (T1 and E1), Phone Handset, Mobile Handset and Ethernet VoIP channels.

In addition to an overall MOS score, the Q-Master can measure within such parameters as; MOS speech only; MOS background only; time delay, MOS vs. Time and many additional measurements. The Q-Master GUI graphically represents all of these measurements.

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.
