Quality
Matrix (QuMax2000) (Single/Double Stimulus Video
Monitoring)
This
is a combo-type monitoring equipment that automatically
monitors video quality and audio errors in real
time.
The QuMax extracts video essences ("Video
DNA") from the source and tested videos and
compares the values at remote locations. Errors
such as video blackouts, freezes, slices, macro
blocks and audio mutes are detected automatically
in real time. The QuMax is used mainly at digital
broadcast systems for master video monitoring.
Applications
- Monitoring at broadcast system master transmission
facilities
- Remote quality monitoring in video networks
- Dubbing quality monitoring
- Quality inspections for videos to be written
to video servers
Characteristics
- Broad range of video formats, including SDTV,
HDTV, and analog systems in both NTSC and PAL
- Maximum of 12 channels of inputs for multi-channel
quality monitoring
- Variety of setting parameters to meet various
objectives
- Easy-to-operate GUI
- Customized alarms incorporated into the monitoring
menu
- Customized control menus to accommodate specific
monitoring needs
