The Cobalt® 9940-4×1-CS 3G/HD/SD-SDI 4×1 Clean and Quiet Bypass Router with Relay-Protected Input and GPIO Monitoring / Control provides Clean & Quiet routing in a high-density card-based openGear® solution. The Clean & Quiet routing not only provides switching on the RP168-specified VANC switch line, but also provides audio cross-fade upon switches to provide video switches free of switching artifacts, and provides dead-quiet audio between switches.
Multiple SDI input ports allow manual selection of input, or failover to alternate inputs (Auto-Changeover) on loss of input conditions. Also included standard is closed captioning absence/presence detection for CEA 608/708 and line 21 SD closed captioning. Option +QC provides user-configurable Video Quality Event intelligent assessments such as black/frozen frame or audio silence. Video Quality or Closed-Captioning event status can independently be propagated for each event type as GPO, automated alert email, input routing changes, or card user presets you can configure to provide any number of special actions such as routing changes or burn-in text alert messages.
Two discrete character burn strings can be inserted on output video, with each string inserted as static text and/or insert only upon LOS. Any of several standard test patterns can be inserted as an input LOS marker. A moving-box insertion can serve as a dynamic raster confidence check even when the input video image is static. Timecode can be received and prioritized among any standard SMPTE embedded or audio LTC timecode, and in turn outputted and burned-in on the output video.
Preset save/load allows saving custom card settings while allowing one-button revert to factory settings. Layered presets allow invoking changes related only to a specific area of concern (audio routing, for example) while not changing any other processing settings or aspects. Full user DashBoard™ or Remote Control Panel remote control allows full status and control access locally or across a standard Ethernet network. GPIO allows direct input routing control and status monitoring.
The 9940-4×1-CS is also available in stand-alone form factor BBG-1040-4×1-CS.
Key Features
Clean & Quiet Routing ensures program video switches free from video artifacts and audio clicks or pops
Multi-input, with manual selection or intelligent Auto-Changeover failover
Closed-captioning absence detection
Auto-Changeover can be set to invoke failover for basic input loss. Quality Check option (+QC) provides alert actions on criteria such as black/frozen frame, audio silence, and closed-captioning absence. Threshold and hold-off are user configurable.
Moving-box/motion insertion enable serves as a dynamic raster confidence check even in cases where the input video image is static
Dual independent burn-in text string insertion allows condition-based insertion (such as basic ID text for valid input and different text message for failover conditions)
Input selection and status can be propagated via GPIO, serial, or IP interfaces
Video options include color correction
Low-power/high-density design – less than 18 Watts per card
Remote control/monitoring via Dashboard™ software or OGCP-9000 remote control panels
Hot-swappable
Five year warranty

Some Rear I/O Modules shown below may also be used for other Cobalt card models. This allows you to re-use rear modules from one card model to another. The Manufacturing Part Number (MPN) shown in the images below is the common code that is used to identify multi-use rear modules. Cross-compatibility can be checked using this number and About Cobalt Rear I/O Modules and Rear Module Cross-Reference at Reference and Help Documents.
