Full‑confidence redundancy from two ASI sources
Ensure the best signal path is always the one being broadcast
Total autonomous operation for lights‑out facilities
The VB243 ASI Intelligent Redundancy Switch Kit leverages Sencore’s proven VideoBRIDGE stream monitoring capabilities into a full, dual-path redundancy switch with autonomous operation. It provides deep signal analysis on both signal paths for unprecedented switching decision making. Front panel controls with illuminated signal path visualization and buttons give local control and provide an at-a-glance overview of switching operations.
Local autonomous operation, remote control by NMS and/or triggers in addition to a SuperLocal mode for complete local override make the VB243 suitable for any real-life operational challenges. The VB243 has multiple layers of redundancy including a dual power supply chassis and magnetically latched broadcast-grade signal relays to protect from any contingency, even a complete power loss.
The VB243 has two ASI inputs, each with taps to feed the included VB242 ASI input module with signals from two different production chains for real-time analysis of both signals. If any problem in any parameter is detected, pre-set rules apply and the unit will check the opposite input for the same failure and switch if no failure is detected. To avoid switch toggling, rules for a minimum time to switch back or manual switchback also can be set. All the parameters in the comprehensive ETR290 engine can be utilized for switch triggering, including detailed CA system validation checks and all priority 1/2/3 parameters.
The VB243 system can be set up to be totally independent and make its own switching decisions, but can also be controlled from an NMS system with extensive Eii (External Integration Interface) parameters or SNMP triggers. All parameters can be controlled using the built-in web GUI which displays a visual overview of parameters used in switch decisions and system status.
