Video Quality Monitoring & Audio Quality Monitoring Products

QuMax-2000
MULTI-CHANNEL BASEBAND VIDEO/AUDIO

 

The QuMax-2000 is a video and audio quality monitoring device for High Definition and Standard Definition that automatically detects video and audio errors in real time.

 

With the capability to monitor up to 12 channels in one box, it’s easy to automate the monitoring of live video services from the control room; and now, use the QuMax-2000 to check Lip Sync along the broadcast chain at the same time! The QuMax-2000 extracts the essence of video and audio signals (“VideoDNA”), detects errors and compares quality. Errors such as video blackouts, freezes, audio mutes are detected automatically, in real time. Quality degradation such as compression strain and audio noise (including 2msec accuracy Lip Sync measurements) are detected by a double stimulus process which compares two signals to each other and alarms if there are differences. No special test signals or potentially harmful markers are needed or used; just any typical audio and video signal with scene changes and audio level changes is adequate. With the small size of the VideoDNA data, remote monitoring can easily be accomplished without the need for large bandwidth networks. Triggered alarms can also be sent via SNMP traps with different “threat” levels so that integration into user’s current systems is painless and allows for different correctional actions to take place based on the “threat” level. The QuMax-2000’s ability to monitor multiple points in a process and/or transmission chain makes it easy to identify exactly which piece of the user’s equipment is inducing the audio or video errors when they occur. QuMax-2000 is covered by Japanese and U.S. patents, issued and pending.

Descriptions and Specifications

 

Chassis -

The QuMax-2000 hardware comes in 3 different rack unit sizes. All functionality is the same; the only difference is the number of probes each chassis can support. Each chassis includes 1 COMM board for network communication.

 

4RU QuMax-2000 –

supports up to 12 probe cards, single or dual power supplies

2RU QuMax-2000 –

supports up to 5 probe cards, single or dual power supplies

1RU QuMax-2000 –

supports only 1 probe card, single power supply only

 

Probe Cards -

Used to convert baseband audio and video into “VideoDNA”.

 

Probe 200 (HD-SDI / SD-SDI Probe Card)

 
 

Video –

1080p/23.98Hz, 1080i/59.94Hz, 1080i/50Hz, 720p/59.94Hz, 720p/50Hz, 480i/59.94Hz, 576i/50Hz

 

Audio –

up to 6 channels embedded audio

 

Probe 210 (Component Probe Card)

 
 

Video –

1080p/23.98Hz, 1080i/59.94Hz, 1080i/50Hz, 720p/59.94Hz, 720p/50Hz, 480i/59.94Hz, 576i/50Hz

 

Audio –

Analog stereo audio

 

Composite Probe Card

 
 

Video –

480i/59.94Hz, 576i/50Hz

 

Audio –

Analog stereo audio

 

Software -

depending on the type and scale of the system, there are different types of software used. All software runs on Windows based OS (Windows XP, Windows Server 2003, and Windows Server 2008)

 

Small Local System

 
 

Stand Alone Software –

for very small systems where all signals can be inputted into 1 QuMax-2000 chassis.

 

Large and/or Remote Systems

 
 

Configuration Console Software –

Setup all network information for multiple QuMax-2000 chassis, DBLS software, and logging software. Set channel naming, comparing, alarm parameters, thresholds, and threat levels. Starting and stopping monitoring. Alarm if any equipment or software “heartbeat” stops.

 

DBLS Software –

each DBLS software can compare up to 30 sets of signals. Sends SNMP trap for each alarm triggered. View in real time the measured values for video delay, audio level difference, luminance difference, and Lip Sync for each set of signals. Can view real time waveform data of signals and records waveform data for each alarm.

 

Logging Software –

receives SNMP traps from DBLS software and stores all alarming information in a database format. Filtering and sorting can be done to easily find desired information. Generates alarming reports over customizable periods of time and for different types of alarms.
