Cobalt Digital 9940-ACO 3G/HD/SD-SDI Multi-Input Intelligent Auto-Changeover Switch
The Cobalt 9940-ACO 3G/HD/SD-SDI Multi-Input IntelligentAuto-Changeover Switch with Optional Trouble Slate Inserter allows manualselection of input, or failover to alternate inputs (Auto-Changeover) on lossof input conditions as well as user-configurable Video Quality Eventintelligent assessments such as black/frozen frame or audio silence. Alsoincluded standard is closed captioning absence/presence detection for CEA608/708 and line 21 SD closed captioning. Video Quality or Closed-Captioningevent status can independently be propagated for each event type as GPO,automated alert email, input routing changes, or card user presets you canconfigure to provide any number of special actions such as routing changes orburn-in text alert messages. A user trouble slate graphic file can be uploadedto the card, which in turn can be automatically inserted in active video if anyVideo Quality Event triggered errors occur.
Two discrete character burn strings can be inserted onoutput video, with each string inserted as static text and/or insert only uponLOS. Any of several standard test patterns can be inserted as an input LOSmarker. A moving-box insertion can serve as a dynamic raster confidence checkeven when the input video image is static. Timecode can be received andprioritized among any standard SMPTE embedded or audio LTC timecode, and inturn outputted and burned-in on the output video.
Preset save/load allows saving custom card settings whileallowing one-button revert to factory settings. Layered presets allow invokingchanges related only to a specific area of concern (audio routing, for example)while not changing any other processing settings or aspects. Full userDashBoardT or Remote-Control Panel remote control allows full status andcontrol access locally or across a standard Ethernet network. GPIO allowsdirect input routing control and status monitoring.
Key Features
- Multi-input, with manual selection or IntelligentAuto-Changeover failover. Latching relay bypass retains manual or failoverinput-to-output routing even in the event of power failure.
- Intelligent Auto-Changeover can be set to invoke failover oralerts for basic input loss as well as intelligent failover/alert based onblack/frozen frame or audio silence. Threshold and hold-off are userconfigurable.
- Video Quality and Closed-Captioning Absence detection andflagging with GPO, automated alert email, input auto-changeover, or engagecustom user preset actions
- Moving-box/motion insertion enable serves as a dynamicraster confidence check even in cases where the input video image is static
- Optional user trouble slate graphic import allows troubleslate to be displayed upon user-selectable input error conditions (such as CCor audio loss, or frozen frame)
- Dual independent burn-in text string insertion allowscondition-based insertion (such as basic ID text for valid input and differenttext message for failover conditions)
- Timecode processing can prioritize, filter for, and convertbetween specific SMPTE embedded-video or audio LTC, with output/burn-intimecode using selected format
- Frame sync with full H/V offset and manual/LOS video patterngenerator. Frame sync can also convert raster format between 29.97/59.94 and30/60 formats.
- Full audio crosspoint with delay control available for allaudio outputs
- Remote control/monitoring via Dashboard software orOGCP-9000 remote control panels
- Hot-swappable
- Five-year warranty

Input Select/Auto-Changeover Failover
Manual selection (forced) of any input.
Failover to alternate input on loss of target input.Failover invoked upon LOS or user configurable parametric criteria such asblack/frozen frame or audio silence.
Black frame trigger configurable for black intensitythreshold and persistence time.
Frozen frame trigger configurable for frozen percentagedifference and persistence time.
