Two Channel Real Time MPEG-2 DVB ASI Failover Switch with Real Time and Sophisticated Transport Stream Monitoring. Complete remote management, setup, and error reporting via web based interface. Created for satellite, cable, and other content where N+1 redundancy in signal paths is crucial. Based on Dell 1950 server with redundant PS and optional RAID drives.

A Broadcast Grade Dual DVB ASI Input Transport Stream "Retimer" and SFN Adapter for Synchronizing 2 ATSC transport streams arriving via different signal paths. (IP and SAT) Designed to provide seamless switching between 2 inputs. Optionally accommodates GPS Input. Suitable for use with ATSC, DVB-T, and other technologies where Transport Streams are the underlying payload.

Two Channel Real Time MPEG-2 DVB ASI Failover Switch with Frame Accurate Real Time Switchover with Sophisticated Transport Stream Monitoring. Complete remote management, setup, and error reporting via web based interface. Created for SFN networks, satellite, cable, and other environments where N+1 redundancy is crucial. Supports 2 ASI inputs and provides both ASI and IP outputs.

• Configurable option to playout a file from a backup source

• Configurable watchdog timer

• 1 RU rackmount Dell 1950 server with redundant PS. Optional RAID configuration.

• Logging history indicates switch state with date and time stamp

• Green and Red Status indicators to indicate active and inactive inputs

• RoHS compliant server with redundant power supply
  

Failover Mechanism:

1. What conditions will trigger the failover?

DVB Guardian will monitor carrier detect and the presence of sync bytes in the stream.



2. Are the conditions user-programmable?

The user can program the length of time that both carrier detect and presence of sync combined is monitored before a failover. This is programmable from 0 to 20 seconds.

Applications:

• Transport stream failover protection in cable head ends
• Transport stream protection in Teleports
• Transport stream protection for On Air video servers

• Unique seamless switch-over between sources
• User programmable switching parameters
• Flexible switching conditions
• Passive and advanced passthru mechanism
• Mirrored outputs
• Full SNMP v2 compliance
• Easy-to-use web-based Graphical User Interface
• Robust, forced cooling, 1RU half 19'' rack mountable
• Ultra compact: up to 4 multiplex in 1RU 19''
• Low power consumption (<20W)
